Hey there! :)
Answer:
x > 9/5.
Step-by-step explanation:
Given:
2/3x - 1/5 > 1
Start by adding 1/5 to both sides:
2/3x > 1 + 1/5
2/3x > 6/5
Divide 2/3 from both sides by multiplying by the reciprocal:
2/3x × 3/2 > 6/5 × 3/2
x > 18/10
Simplify:
x > 9/5.
Based upon market research, the Hawthorne Company has determined that consumers are willing to purchase 135 units of their portable media player each week when the price is set at $26.10 per unit. At a unit price of $9.10, consumers are willing to buy 305 units per week.
Required:
a. Determine the weekly demand equation for this product, assuming price, p, and quantity, x, are linearly related.
b. Determine the weekly revenue function.
c. Determine the number of units consumers will demand weekly when the price is $93.00 per portable media player.
d. Determine the number of units consumers will demand weekly when the revenue is maximized.
e. Determine the price of each unit when the revenue is maximized
Answer:
a. P= -0.1x + 39.6
b. R(x) = -0.1x^2 + 39.6x
c. x = -534 units
d. Number of units demand weekly when the revenue is maximized is 198 units
e. Price p = 15.8 units
Step-by-step explanation:
So for the demand equation let price =p
x= number of units sold
m = per unit price
b = initial fix amount
a. p = mx + b
When p = 26.10 $, x = 135 units so equation
26.10 = m(135) + b .......................(1)
When p = 9.10, x = 305 units so equation
9.10 = m(305) + b .......................(2)
subtracting equation (2) from equation (1)
26.10 - 9.10 =135x +b - 305x - b
17.00 = -170m
m= 17/-170
m= -0.1
Lets plug the value of m in the first equation
26.10 = m(135) + b
26.10 = (-0.1)(135) + b
26.10 = -13.5 + b
b= 26.10 + 13.5
b= 39.6
So the equation would be P= -0.1x + 39.6
b. Revenue = price * quantity
R(x) = p * x
R(x) = x (-0.1x + 39.6)
R(x) = -0.1x^2 + 39.6x
c. Here we have p = $ 93.00
P= -0.1x + 39.6
93 = -0.1x + 39.6
93 - 39.6 = -0.1x
-0.1x = 53.4
x = 53.4 / -0.1
x = -534 units
d. R(x) = -0.1x^2 + 39.6x
On differentiating it with respect to x.
R'(x) = -0.1(2)x^2-1 + 39.6x^1-1
R'(x) = -0.2x + 39.6
So for the maximum revenue differentiation of revenue function must be 0.
0 = -0.2x + 39.6
0.2x = 39.6
x = 39.6 / 0.2
x = 198 units
Number of units demand weekly when the revenue is maximized is 198 units
e. Price p = -0.1x + 39.6
on plugging the value x =238
Price p = -0.1(238) + 39.6
Price p = -23.8 + 39.6
Price p = 15.8 units
A lady buys bananas at 3 Rs 5 and sells them at 2 Rs for Rs 5; find her gain percent.
Answer:
50%
Step-by-step explanation:
Cost of 3 bananas= Rs. 5 ⇒ cost of 1 banana= Rs. 5/3
Selling price of 2 bananas= Rs. 5 ⇒ selling price of 1 banana= Rs. 5/2
Gain= Rs. (5/2- 5/3)= Rs. (15/6- 10/6)= Rs. 5/6
Gain %= 5/6÷5/3 × 100%= 50%

Make x the subject of the formula a x + 2 c = b x + 3 d
Answer:
x = (3d - 2c)/(a - b)
Step-by-step explanation:
ax + 2c = bx + 3d
ax - bx = 3d - 2c
x(a - b) = 3d - 2c
x = (3d - 2c)/(a - b)
Answer:
[tex]\boxed{x = \frac{3d-2c}{a-b}}[/tex]
Step-by-step explanation:
=> [tex]ax+2c = bx+3d[/tex]
Subtracting bx to both sides
=> [tex]ax-bx+2c= 3d[/tex]
Subtracting 2c to both sides
=> [tex]ax-bx = 3d-2c[/tex]
Taking x common
=> [tex]x(a-b) = 3d-2c[/tex]
Dividing both sides by (a-b)
=> [tex]x = \frac{3d-2c}{a-b}[/tex]

Adelphi Company purchased a machine on January 1, 2017, for $60,000. The machine was estimated to have a service life of ten years with an estimated residual value of $5,000. Adelphi sold the machine on January 1, 2021 for $21,000. Adelphi uses the double declining method for depreciation. Using this information, how much is the gain or (loss) for the equipment sale entry made on January 1, 2021. Enter a loss as a negative number.
Answer:
-$3576
Step-by-step explanation:
Depreciation using double declining method=100%/useful life*2
Depreciation using double declining method=100%/10*2=20%
2017 depreciation=$60,000*20%=$12000
2018 depreciation=($60,000-$12000)*20%=$9600
2019 depreciation=($60,000-$12000-$9600 )*20%=$7680
2020 depreciation=($60,000-$12000-$9600-$7680 )*20%=$6144
carrying value in 2021=$60000-$12000-$9600 -$7680-$6144 =$24576
Loss on disposal of machine=$21,000-$24576 =-$3576
excel A car insurance company has determined that 8% of all drivers were involved in a car accident last year. If 15 drivers are randomly selected, what is the probability of getting 3 or more who were involved in a car accident last year
Answer:
[tex] P(X \geq 3)= 1- P(X<3)= 1-P(X \leq 2)= 1- [P(X=0) +P(X=1) +P(X=2)][/tex]
And we can find the individual probabilites using the probability mass function and we got:
[tex] P(X=0) = (15C0) (0.08)^{0} (1-0.08)^{15-0}=0.286 [/tex]
[tex] P(X=1) = (15C1) (0.08)^{1} (1-0.08)^{15-1}=0.373 [/tex]
[tex] P(X=2) = (15C2) (0.08)^{2} (1-0.08)^{15-2}=0.227 [/tex]
And replacing we got:
[tex] P(X\geq 3) = 1-[0.286+0.373+0.227 ]= 0.114[/tex]
Step-by-step explanation:
For this case we can assume that the variable of interest is "drivers were involved in a car accident last year" and for this case we can model this variable with this distribution:
[tex] X \sim Bin (n =15, p =0.08)[/tex]
And for this case we want to find this probability;
[tex] P(X \geq 3)[/tex]
and we can use the complement rule and we got:
[tex] P(X \geq 3)= 1- P(X<3)= 1-P(X \leq 2)= 1- [P(X=0) +P(X=1) +P(X=2)][/tex]
And we can find the individual probabilites using the probability mass function and we got:
[tex] P(X=0) = (15C0) (0.08)^{0} (1-0.08)^{15-0}=0.286 [/tex]
[tex] P(X=1) = (15C1) (0.08)^{1} (1-0.08)^{15-1}=0.373 [/tex]
[tex] P(X=2) = (15C2) (0.08)^{2} (1-0.08)^{15-2}=0.227 [/tex]
And replacing we got:
[tex] P(X\geq 3) = 1-[0.286+0.373+0.227 ]= 0.114[/tex]
The total area under the standard normal curve to the left of zequalsnegative 1 or to the right of zequals1 is
Answer:
0.3174
Step-by-step explanation:
Z-score:
The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the area under the normal curve to the left of Z. Subtracting 1 by the pvalue, we find the area under the normal curve to the right of Z.
Left of z = -1
z = -1 has a pvalue of 0.1587
So the area under the standard normal curve to the left of z = -1 is 0.1587
Right of z = 1
z = 1 has a pvalue of 0.8413
1 - 0.8413 = 0.1587
So the area under the standard normal curve to the right of z = 1 is 0.1587
Left of z = -1 or right of z = 1
0.1587 + 0.1587 = 0.3174
The area is 0.3174

Researchers wanted to know whether it is better to give the diphtheria, tetanus and pertussis (DTaP) vaccine in the thigh or the arm. They collect data on severe reactions to this vaccine in children aged 3 to 6 years old. What would be the best statistical test for them to utilize?
A. One-sample chi-square
B. Linear regression
C. T-test
D. Two-sample chi-square
Answer:
D. Two-sample chi-square
Step-by-step explanation:
A chi-square test is a test used to compare the data that is observed, from the data that is expected.
In a two-sample chi-square test the observed data should be similar to the expected data if the two data samples are from the same distribution.
The hypotheses of the two-sample chi-square test is given as:
H0: The two samples come from a common distribution.
Ha: The two samples do not come from a common distribution
Therefore, in this case, the best statistical test to utilize is the two-sample chi-square test.

Do you think that it is possible to obtain a good indication of the precise degree of protection accorded by a country to its import-substitute industries? Why or why not? (Remember that, in addition to tariffs, protection is also provided by various non-tariff barriers.)
Answer:
The answer is below
Step-by-step explanation:
First we have that free trade refers to the movement of goods, services, capital and knowledge from one place to another. But in reality, free trade does not exist since there are many tariffs and non-tariff barriers.
However,
- Tariff barriers are taxes imposed on imports into a country according to quantity or quantity. Tariff barriers increase the price of imports in the country, which affects the demand for goods and services. Countries agree to lower these tariff barriers, which make trade reasonable for countries that sign agreements.
- Non-tariff barriers are barriers that do not directly affect import prices. It does not impose a tax directly on imports. It tries to reduce imports by using barriers other than taxes.
Therefore countries try to protect their domestic industries using various tariff and non-tariff barriers. The amount of the barriers cannot be precisely decided, since the barriers are not only to protect national industries, but some barriers are imposed to avoid the economic and political monopoly of a foreign country in the national country.
Government actions:
The government applies various health and safety regulations to domestic and foreign products, since consumers in the country must be protected against any impurities. Still, these restrictions are also more than required, leading to protectionism.
The government uses various tariff and non-tariff barriers not only to protect national industries but also for various social, economic, and political reasons.
Therefore, it is difficult to establish tariff and non-tariff barriers in a country accurately.
How do you determine whether the sign of a trigonometric function (sine, cosine, tangent) is positive or negative when dealing with half angles? Explain your reasoning and cite examples. Why do you think the half-angle identities include positive and negative options but the other identities don't seem to have this option built in?
Answer:
This question is about:
sin(A/2) and cos(A/2)
First, how we know when we need to use the positive or negative signs?
Ok, this part is kinda intuitive:
First, you need to know the negative/positve regions for the sine and cosine function.
Cos(x) is positive between 270 and 90, and negative between 90 and 270.
sin(x) is positive between 0 and 180, and negative between 180 and 360.
Then we need to see at the half-angle and see in which region it lies.
If the half-angle is larger than 360°, then you subtract 360° enough times such that the angle lies in the range between (0° and 360°)
and: Tan(A/2) = Sin(A/2)/Cos(A/2)
So using that you can infer the sign of the Tan(A/2)
Now, why these relationships use the two signs?
Well... this is because of the square root in the construction of the relationships.
This happens because:
(-√x)*(-√x) = (-1)*(-1)*(√x*√x) = (√x*√x)
For any value of x.
so both -√x and √x are possible solutions of these type of equations, but for the periodic nature of the sine and cosine functions, we can only select one of them.
So we should include the two possible signs, and we select the correct one based on the reasoning above.
if my medical expenses are $40,000 per year for 35 years with an increase of 6% a year what is the total amount?
Answer:
$4,457,391.19
Step-by-step explanation:
The sum of n terms of a geometric sequence with common ratio r and initial value "a" is ...
S = a(r^n -1)/(r -1)
Here, your growth factor is r = 1 +6% = 1.06. So, the sum of expenses over 35 years will be ...
S = $40,000(1.06^35 -1)/(1.06 -1) = $4,457,391.19

what is 1% of 62 like i dont understand this
Answer:
0.62
Step-by-step explanation:
1. We assume, that the number 62 is 100% - because it's the output value of the task.
2. We assume, that x is the value we are looking for.
3. If 62 is 100%, so we can write it down as 62=100%.
4. We know, that x is 1% of the output value, so we can write it down as x=1%.
5. Now we have two simple equations:
1) 62=100%
2) x=1%
where left sides of both of them have the same units, and both right sides have the same units, so we can do something like that:
62/x=100%/1%
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.
7. Solution for what is 1% of 62
62/x=100/1
(62/x)*x=(100/1)*x - we multiply both sides of the equation by x
62=100*x - we divide both sides of the equation by (100) to get x
62/100=x
0.62=x
x=0.62
now we have:
1% of 62=0.62

Suppose that the scores of bowlers in particular league follow a normal distribution such that the standard deviation of the population is 6. Find the 95% confidence interval of the mean score for all bowlers in this league, using the accompanying data set of 10 random scores. Round your answers to two decimal places and use ascending order. Score 86 86 93 88 98 107 93 75 89
Answer:
A 95% confidence interval for the population mean score for all bowlers in this league is [86.64, 94.48].
Step-by-step explanation:
Since in the question only 9 random scores are given, so I am performing the calculation using 9 random scores.
We are given that the scores of bowlers in particular league follow a normal distribution such that the standard deviation of the population is 6.
The accompanying data set of 9 random scores in ascending order is given as; 75, 86, 86, 88, 89, 93, 93, 98, 107
Firstly, the pivotal quantity for finding the confidence interval for the population mean is given by;
P.Q. = [tex]\frac{\bar X-\mu}{\frac{\sigma}{\sqrt{n} } }[/tex] ~ N(0,1)
where, [tex]\bar X[/tex] = sample mean score = [tex]\frac{\sum X}{n}[/tex] = [tex]\frac{815}{9}[/tex] = 90.56
[tex]\sigma[/tex] = population standard deviation = 6
n = sample of random scores = 9
[tex]\mu[/tex] = population mean score for all bowlers
Here for constructing a 95% confidence interval we have used a One-sample z-test statistics because we know about population standard deviation.
So, 95% confidence interval for the population mean, [tex]\mu[/tex] is ;
P(-1.96 < N(0,1) < 1.96) = 0.95 {As the critical value of z at 2.5% level
of significance are -1.96 & 1.96}
P(-1.96 < [tex]\frac{\bar X-\mu}{\frac{\sigma}{\sqrt{n} } }[/tex] < 1.96) = 0.95
P( [tex]-1.96 \times {\frac{\sigma}{\sqrt{n} } }[/tex] < [tex]\bar X-\mu}[/tex] < [tex]1.96 \times {\frac{\sigma}{\sqrt{n} } }[/tex] ) = 0.95
P( [tex]\bar X-1.96 \times {\frac{\sigma}{\sqrt{n} } }[/tex] < [tex]\mu[/tex] < [tex]\bar X+1.96 \times {\frac{\sigma}{\sqrt{n} } }[/tex] ) = 0.95
95% confidence interval for [tex]\mu[/tex] = [ [tex]\bar X-1.96 \times {\frac{\sigma}{\sqrt{n} } }[/tex] , [tex]\bar X+1.96 \times {\frac{\sigma}{\sqrt{n} } }[/tex] ]
= [ [tex]90.56-1.96 \times {\frac{6}{\sqrt{9} } }[/tex] , [tex]90.56+1.96 \times {\frac{6}{\sqrt{9} } }[/tex] ]
= [86.64 , 94.48]
Therefore, a 95% confidence interval for the population mean score for all bowlers in this league is [86.64, 94.48].

ASK YOUR TEACHER Does the function satisfy the hypotheses of the Mean Value Theorem on the given interval? f(x) = x3 + x − 9, [0, 2]
Answer:
Yes
Step-by-step explanation:
The Mean Value Theorem states that if f(x) is defined and continuous on the interval [a,b] and differentiable on (a,b), then there is at least one number c in the interval (a,b) (that is a < c < b) such that
[tex]f'(c)=\dfrac{f(b)-f(a)}{b-a}[/tex]
Given [tex]f(x)=x^3+x-9$ in [0,2][/tex]
f(x) is defined, continuous and differentiable.
[tex]f(2)=2^3+2-9=1\\f(0)=0^3+0-9=-9[/tex]
[tex]f'(c)=\dfrac{f(2)-f(0)}{2-0}=\dfrac{1-(-9)}{2}=5[/tex]
[tex]f'(x)=3x^2+1[/tex]
Therefore:
[tex]f'(c)=3c^2+1=5\\3c^2=5-1\\3c^2=4\\c^2=\frac{4}{3} \\c=\sqrt{\frac{4}{3}} =1.15 \in [0,2][/tex]
Since c is in the given interval, the function satisfy the hypotheses of the Mean Value Theorem on the given interval.

Find the surface area of this composite solid. I Need answer ASAP Will give brainliest
Answer:
B. 120 m²
Step-by-step explanation:
To find the surface area of the composite solid, we would need to calculate the area of each solid (square pyramid and square prism), then subtract the areas of the sides that are not included as surface area. The sides not included as surface area is the side the pyramid and the prism is joint together.
Step 1: find the surface area of the pyramid:
Surface area of pyramid with equal base sides = Base Area (B) + ½ × Perimeter (P) × Slant height (l)
Base area = 4² = 16 m
Perimeter = 4(4) = 16 m
Slant height = 3 m
Total surface area of pyramid = 16 + ½ × 16 × 3
= 16 + 8 × 3 = 16 + 24
= 40 m²
Step 2: find the area of the prism
Area = 2(wl + hl + hw)
Area = 2[(4*4) + (5*4) + (5*4)]
Area = 2[16 + 20 + 20]
Area of prism = 2[56] = 112 m²
Step 3: Find the area of the sides not included
Area of the sides not included = 2 × area of the square base where both solids are joint
Area = 2 × (4²)
Area excluded = 2(16) = 32 m²
Step 4: find the surface area of the composite shape
Surface area of the composite shape = (area of pyramid + area of prism) - excluded areas
= (40m²+112m²) - 32m²
= 152 - 32
Surface area of composite solid = 120 m²
Please check my answer! The faculty at a particular school have attended up to an average 4 years of college with a standard deviation of 2 years. Faculty members who are in the lower 10% of the distribution will be offered the opportunity to obtain additional training. A faculty member must have attended less than ___________ years of school to qualify for the training. Round your answer to the year. My answer: 1 – 0.10 = 0.90 0.9 - 0.5 = 0.40 z-score = 1.28 (corresponds with 0.3997) x = (1.28)(2) + 4 = 7 years (rounded)
Answer:
1 year
Step-by-step explanation:
1. Convert 10% into a z-score, using a calculator or whateva
2. Z = -1.281551 ( you can find this by doing the following equation: (x - mean) / (standard deviation)
3. Hence -1.281551 = (x - 4) / 2 or, x = 1.436898, ( rounded to the nearest year ) = 1 year
