Answer: 186
Step-by-step explanation:
Jazz Rock or Pop
7-12: 200 - 142 = 58 142
13-18: 72 - 58 = 14 200 - 14 = 186
It is given that 142 out of 200 students in age group 7-12 like Rock or Pop.
Therefore, 200-142 = 58 in that age group like Jazz.
Total Jazz in both age groups is 72, so 72 - 58 (7-12: Jazz) = 14 students in age group 13-18 like Jazz.
There are 400 students total and 200 are in age group 7-12, which leaves 400-200 students in age group 13-18. 200 - 14 (13-18: Jazz) = 186 students in age group 13-18 like Rock or Pop.

The claim that the mean amount of sleep for adults is less than 7 hours. Choose the correct statement about null and alternative hypothesis.
a) H0: µ > 7 hours (null hypothesis)
H1: µ < 7 hours (alternative hypothesis and original claim)
b) H0: µ = 7 hours (null hypothesis)
H1: µ < 7 hours (alternative hypothesis and original claim)
H2: µ > 7 hours (second alternative hypothesis and original claim)
c) H0: µ = 7 hours (null hypothesis)
H1: µ < 7 hours (alternative hypothesis and original claim)
d) H0: µ < 7 hours (null hypothesis)
H1: µ ≥≥ 7 hours (alternative hypothesis and original claim)
Answer:
c) H0: µ = 7 hours (null hypothesis)
H1: µ < 7 hours (alternative hypothesis and original claim)
Step-by-step explanation:
The hypothesis test is performed in order to see if a sample outcome gives evidence to reject a null hypothesis and support the researchers claim.
In this case, the claim is that the mean amount of sleep for adults is less than 7 hours.
For this claim, the alternative hypothesis will state the researcher's claim: the mean amount of sleep for adults is significantly less than 7 hours.
The null hypothesis will state the opposite: the mean amount of sleep for adults is not significantly less than 7 hours. In this case, it is the same to claim that the mean amount is 7 hours.
Then, the null and alternative hypothesis are:
[tex]H_0: \mu=7\\\\H_a:\mu< 7[/tex]
p is a rectangle with lengths 60cm and width x cm q is a rectangle with width y cm. the length of q is 20% more than the length of p the area of p is 15% less than the area of q work out the ratio x:y
Answer:
The ratio of x to y is
1.02/1 = x/y
1.02:1= x:y
Step-by-step explanation:
Rectangle p
Length = 60 cm
Width = x cm
Area = length* breadth
Area = 60 *x
Rectangle q
Length = 20% more than length of rectangle p
Length = (60*0.2) + 60
Length = 12 +60
Length = 72cm
Width = y cm
Area = 72*y
(72*y)-(72*y *0.15)= 60*x
72y - 10.8y = 60x
61.2y = 60x
61.2/60 = x/y
15.3/15= x/y
5.1/5 = x/y
1.02/1 = x/y
According to a polling organization, 22% of adults in a large region consider themselves to be liberal. A survey asked 200 respondents to disclose their political philosophy: Conservative,Liberal, And Moderate. Treat the results of the survey as a random sample of adults in this region. Do the survey results suggest the proportion is higher than that reported by the pollingorganization? Use an alpha =0.05 level of significance.
75- Liberal
65- Moderate
61- Conservative
Answer:
Step-by-step explanation:
Using the proportion test
Null hypothesis: p <= 0.22
Alternative hypothesis: p > 0.22
Using the formula
z score = p - P /√ (P(1-P)/n)
Where p is 74/200= 0.37, P = 0.22, n = 200.
0.37-0.22 / √(0.22(1-0.22)/200)
0.15 / √(0.22(0.78)/200)
0.15 / √(0.1716/200)
0.15/ √0.000858
0.15 / 0.02929
= 5.1212
To help arrive at a conclusion, we have to find the p value, using a p value calculator at the 0.05 level of significant, the p value is less than 0.00001... Thus we would reject the null as there is sufficient statistical evidence to prove that the proportion is higher than that reported by the polling organization.
Find the most general antiderivative of the function. (Check your answer by differentiation. Use C for the constant of the antiderivative.) f(x) = 8x3/5 + 3x−4/5
Answer:
[tex]\dfrac{8x^{4}}{20}+\dfrac{3x^{2}}{2}-\dfrac{4}{5}x+C[/tex]
Step-by-step explanation:
Given the function: [tex]f(x)=\dfrac{8x^3}{5}+3x-\dfrac{4}{5}[/tex]
To take the antiderivative (or integral) of a function, we follow the format below.
[tex]f(x)=x^n\\$Then its antiderivative\\Antiderivative of f(x)$=\dfrac{x^{n+1}}{n+1}[/tex]
Therefore, the antiderivative of f(x) is:
[tex]=\dfrac{8x^{3+1}}{5(3+1)}+\dfrac{3x^{1+1}}{2}-\dfrac{4}{5}x+C\\=\dfrac{8x^{4}}{20}+\dfrac{3x^{2}}{2}-\dfrac{4}{5}x+C[/tex]
We want to check our result by differentiation.
[tex]\dfrac{d}{dx}\left(\dfrac{8x^{4}}{20}+\dfrac{3x^{2}}{2}-\dfrac{4}{5}x+C\right)\\=\dfrac{d}{dx}\left(\dfrac{8x^{4}}{20}\right)+\dfrac{d}{dx}\left(\dfrac{3x^{2}}{2}\right)-\dfrac{d}{dx}\left(\dfrac{4}{5}x\right)+\dfrac{d}{dx}\left(C\right)\\\\=\dfrac{32x^{3}}{20}+\dfrac{6x}{2}-\dfrac{4}{5}+0\\\\=\dfrac{8x^{3}}{5}+3x-\dfrac{4}{5}[/tex]

Which graph shows the system StartLayout Enlarged left-brace 1st row x squared + y = 2 2nd row x squared + y squared = 9 EndLayout?
Answer: Hope this helps <3
Step-by-step explanation:
Graphs can be used to represent functions.
See attachment for the graphs of [tex]\mathbf{x^2 + y = 2}[/tex] and [tex]\mathbf{x^2 + y^2 = 9}[/tex]
The functions are given as:
[tex]\mathbf{x^2 + y = 2}[/tex]
[tex]\mathbf{x^2 + y^2 = 9}[/tex]
Rewrite [tex]\mathbf{x^2 + y^2 = 9}[/tex] as:
[tex]\mathbf{x^2 + y^2 = 3^2}[/tex]
The above equation represents a circle of radius 3, and that has its center as the origin.
Similarly, we have:
[tex]\mathbf{x^2 + y = 2}[/tex]
Make y the subject
[tex]\mathbf{y = 2 -x^2}[/tex]
Rewrite as:
[tex]\mathbf{y = -x^2 + 2 }[/tex]
The above is a square function, that is reflected over the y-axis, and then shifted up by 2 units.

A model for consumers' response to advertising is given by the equation N(a)=2600 + 470ln (a) Where N(a) is the number of units sold, a is the amount spent on advertising, in thousands of dollars, & a≥1.
Required:
a. How many units were sold after spending $1,000 on advertising?
b. Find N′(a).
c. Find the maximum value, if it exists.
d. Find lim a→[infinity] N′(a).
Answer:
a. [tex]N(1)=2600[/tex]
b. [tex]N'(a) = 470/a[/tex]
c. N(a) has no maximum value, max N'(a) = 470 (when a = 1)
d. lim a→[infinity] N′(a) = 0
Step-by-step explanation:
a.
the variable 'a' is the amount spent in thousands of dollars, so $1,000 is equivalent to a = 1. Then, we have that:
[tex]N(1)=2600 + 470ln(1)[/tex]
[tex]N(1)=2600 + 470*0[/tex]
[tex]N(1)=2600[/tex]
b.
To find the derivative of N(a), we need to know that the derivative of ln(x) is equal (1/x), and the derivative of a constant is zero. Then, we have:
[tex]N'(a) = 2600' + (470ln(a))'[/tex]
[tex]N'(a) = 0 + 470*(1/a)[/tex]
[tex]N'(a) = 470/a[/tex]
c.
The value of 'ln(a)' increases as the value of 'a' increases from 1 to infinity, so there isn't a maximum value for N(a).
The maximum value of N'(a) is when the value of a is the lower possible, because 'a' is in the denominator, so the maximum value of N'(a) is 470, when a = 1.
d.
When the value of 'a' increases, the fraction '470/a' decreases towards zero, so the limit of N'(a) when 'a' tends to infinity is zero.

Find the missing length to the nearest tenth.
Right Triangle
6 m
C
16 m
Answer:
17.1 meters
Step-by-step explanation:
Since this is a right triangle, we can use the Pythagorean Theorem.
[tex]a^2+b^2=c^2[/tex]
where a and b are the legs and c is the hypotenuse.
6 and 16 are the legs, because they form the right angle. c is the hypotenuse because it is opposite the right angle.
[tex]6^2+16^2=c^2[/tex]
Evaluate the exponents.
6^2= 6*6= 36
16^2= 16*16= 256
[tex]36+256=c^2[/tex]
Add 36 and 256.
[tex]292=c^2[/tex]
Since c is being squared, take the square root of both sides of the equation. The exponent and square root will cancel and leave c by itself
[tex]\sqrt{292} =\sqrt{c^2}[/tex]
[tex]\sqrt{292}=c[/tex]
[tex]17.0880075=c[/tex]
Round to the nearest tenth. The 8 in the hundredeth place tells us to roung the 0 in the tenth place up to a 1.
[tex]17.1=c[/tex]
c= 17.1 m
The missing length, or the hyptenuse is 17.1 meters.

Determine whether the sequence converges or diverges. If it converges, find the limit. an = 9 + 14n2 n + 15n2 Step 1 To find lim n → [infinity] 9 + 14n2 n + 15n2 , divide the numerator and denominator by the highest power of n that occurs in the fraction. This is n .
Answer:
The sequence ConvergesStep-by-step explanation:
Given the sequence [tex]a_n = \frac{9+14n^{2} }{n+15n^{2} }[/tex]
To find the limit of the sequence, we will first divide the numerator and the denominator through by the highest power of n which is n² as shown;
[tex]\lim_{n \to \infty} \frac{9/n^{2} +14n^{2}/n^{2} }{n/n^{2} +15n^{2}/n^{2} }\\ \lim_{n \to \infty} \frac{9/n^{2} +14 }{1/n +15n^{2}/n^{2 }}\\[/tex]
As [tex]n[/tex] tends to [tex]\infty[/tex], [tex]\frac{a}{n}[/tex] tends to zero where n is any constant, The limit of tyhe sequence as n tends to infinity becomes;
[tex]= \frac{9/\infty+14 }{1/\infty+15 }\\= \frac{0+14}{0+15} \\= 14/15\\[/tex]
Therefore [tex]\lim_{n \to \infty} \frac{9+14n^{2} }{n+15n^{2} } = 14/15[/tex]
Since the limit of the sequence gave a finite number , the sequence converges.
Note that the only case when the sequence diverges id when the limit of the sequence is infinite
Consider a data set containing the following values:
70 65 71 78 89 68 50 75
The mean of the preceding values is:
70.75.
The deviations for the mean have been calculated as follows:
-0.75, -5.75, 0.25,7.25,18.25,-2.75,-20.75, and 4.25
a. If this is the sample data, the sample variance is _____ and the sample standard deviation is ___
b. If this is a population data, the population variance is_____ and the population standard deviation is_____
Answer:
a. 125.0714; 11.1835.
b. 109.4375; 10.4612.
Step-by-step explanation:
Given the following data;
70, 65, 71, 78, 89, 68, 50, 75.
Mean = 70.75
The deviation for the mean of the data is -0.75, -5.75, 0.25,7.25,18.25,-2.75,-20.75, and 4.25.
We would then find the square of this deviation;
[tex]=(-0.75)^2+(-5.75)^2+( 0.25)^2+(7.25)^2 +(18.25)^2+(-2.75)^2+(-20.75)^2 +(4.25)^2[/tex]
[tex]=0.5625+33.0625+0.0625+52.5625+333.0625+7.5625+430.5625+18.0625[/tex]
= 875.5
Next is to find the population variance;
[tex]V = \frac{875.5}{8}[/tex]
Variance, V = 109.4375
The population standard deviation is the square root of the population variance;
[tex]Sd = \sqrt{109.4375}[/tex]
Standard deviation, Sd = 10.4612
To find the sample variance;
[tex]V = \frac{875.5}{8-1}[/tex]
[tex]V = \frac{875.5}{7}[/tex]
Variance, V = 125.0714
The sample variance is;
[tex]Sd = \sqrt{125.0714}[/tex]
Standard deviation, Sd = 11.1835
Therefore,
a. The sample variance is 125.0714 and the sample standard deviation is 11.1835.
b. If this is a population data, the population variance is 109.4375 and the population standard deviation is 10.4612.

= {1,3,6,9,12,15,18,24}
In a family, the probability that a child is female is 0.6. if there are thee children in the family, what is the probability that 1. Exactly 2 are girls 2. At least 1 is a boy
Answer:1.P(exactly 2 kids are girls)=3/8
2. P(at least 1 is boy)=7/8
Step-by-step explanation:
1.P(exactly 2 kids are girls)=N(outcomes with 2 girls) /Total number of outcomes.
All possible outcomes are ggb,gbg, bgg, gbb, bgb, bbg, ggg, bbb - total 8
Outcomes where are exactly 2 girls are:
ggb,gbg, bgg - total 3 outcomes
So P(exactly 2 are girls)=3/8
2. P(at least 1 is boy)=Number of outcomes , where are at least 1 boy (1,2 or all 3 kids are boys)/ Total number of outcomes
All possible outcomes are ggb,gbg, bgg, gbb, bgb, bbg, ggg, bbb - total 8
Outcomes, where at least 1 kid is boy: ggb,gbg, bgg, gbb, bgb, bbg, bbb - total 7
P(at least 1 is boy)=7/8

Makya was conducting a physics experiment. He rolled a ball down a ramp and calculated the distance covered by the ball at different times. The ball rolled a distance of 1 foot during the first second, 3 feet during the next second, and so on. If the distances the ball rolled down the ramp each second form an arithmetic sequence, determine the distance the ball rolled down during the fifteenth second. (Show work)
Hey there! :)
Answer:
f(15) = 29 ft.
Step-by-step explanation:
We can write an arithmatic equation for this pattern:
Where:
[tex]n_{1}[/tex] = 1, [tex]n_{2}[/tex] = 3
Find the rate of change. This is constant because this is an arithmatic sequence.
3 - 1 = 2.
We can begin to write an explicit function for this situation:
f(n) = [tex]n_{1}[/tex] + d(n-1) where d is the rate of change:
f(n) = 1 + 2(n-1)
Substitute 15 for n to solve for the distance traveled after 15 seconds:
f(15) = 1 + 2(15-1)
f(15) = 1 + 2(14)
f(15) = 1 + 28
f(15) = 29 ft.
Therefore, the distance traveled after 15 seconds is 29 ft.
g Determine the area of the region between the two curves by integrating over the x-axis. y = x2 − 24 and y = 1
Answer:
A = 166.66
Step-by-step explanation:
You have the following functions:
[tex]y_1=x^2-24\\\\y_2=1[/tex]
In order to calculate the area of the given region, you first calculate the points at which the function y = x^2-24 intersects the line y=1:
[tex]1=x^2-24\\\\0=x^2-25\\\\x=\sqrt{25}=\pm 5[/tex]
Next, you take into account that the area between the two function is given by:
Where you have used the fact that y2 is above the y1 function.
Next, you calculate the following integral:
[tex]A=\int_{-5}^{5}(1-(x^2-24))dx=\int_{-5}^{5}(25-x^2)dx\\\\A=(25x-\frac{1}{3}x^3)|_{-5}^{5}\\\\A=(25(5)-\frac{1}{3}(125))-(25(-5)-\frac{1}{3}(-125))\\\\A=166.66[/tex]
Then, the area of the bounded region is 166.66

Step-by-step explanation:
Given the equality y > -½, it means the values of y is greater than -½.
The values of y would range from 0 upwards. I.e. 0, ½, 1, 1½, 2. . .
Thus, when graphed on a number line, the circle that appears like "o" would start from -½, and the "o" would not be full or shaded to indicate that -½ is not included in the values of y, which are greater than -½. Since the values of y are greater than -½ the direction of the arrow that indicates values of y would point towards our far right, to indicate the values included as y.
Therefore, the graph that indicates the inequality y > ½ is A

LK / sin J = LJ / sin K
LK = 9
J = 89°
K = 23°
So now LJ is
9 / sin 89° = LJ / sin 23°
Make LJ the subject
That's
LJ = 9 sin 23° / sin 89°
LJ = 3.51
The final answer is
LJ = 3.5Hope this helps you.

To increase and increase an amount by 70%
what single multiplier would you use?
Answer:
Increase: 1.7
Decrease: 0.3
Step-by-step explanation:
Increase:
100% + 70% = 117%
117/ 100 = 1.7 (multiplier)
Decrease:
100% - 70%= 30%
30/ 100 = 0.3 (multiplier)
