a.The time it takes to fly from City Upper A to City Upper B is a continuous random variable.
Step-by-step explanation:
When the value of the variable is found by counting the variables, it is termed as a discrete variable.When the value of the variable is found by measuring the variables, it is termed as a continuous variable.In (c) and (d), the values of the variables can be found by counting. The number of fish and the number of textbook authors can be counted. Hence, they are discrete random variable.
In (a), (b) and (e) the values can be found by measuring. The time taken to fly, the time taken for light to travel and the distance to travel are the variable that are measured. Hence, they are continuous random variable.

A retail store sells two types of shoes, sneakers and sandals. The store owner pays $8 for the sneakers and $14 for the sandals. The sneakers can be sold for $10 and the sandals can be sold for $17. The owner of the store estimates that she won't sell more than 200 shoes each month, and doesn't plan to invest more that $2,000 on inventory of the shoes. Let x= the number of sneakers in stock, and y=the number of sandals in stock. Write an equation to show the profit she will make on sneakers and sandals. P = [answer0]
Answer:
The equation that shows the profit: P = 2x + 3y
Step-by-step explanation:
The number of sneaker = x
The number of sandals = y
Cost of sneaker = 8 dollars.
Cost of sandals = 14 dollars.
Selling price of sneaker = $10
Selling price of sandals = $17
Total revenue = $10x + $17y
Total cost = $8x + $14y
Profit (P) = Total revenue - Total cost.
Profit = ($10x + $17y) – ($8x + $14y)
P = 10x +17y – 8x – 14y
P = 2x + 3y

Given that the sum of the first n terms of the provided series is 6560 determine the value of n (2,6,18,54....)
Answer:
n = 8
Step-by-step explanation:
The given sequence, 2, 6, 18, 54. . ., is a geometric sequence.
It has a common ratio of 3 => [tex] \frac{6}{2} = \frac{18}{6} = \frac{54}{18} = 3 [/tex]
Thus, the sum of the first n terms of a geometric sequence is given as [tex]S_n = \frac{a_1(1 - r^n)}{1 - r}[/tex]
Where,
[tex] a_1 [/tex] = first term of the series = 2
r = common ratio = 3
[tex] S_n [/tex] = sum of the first n terms = 6,560
Plug in the above values into the formula
[tex]6,560 = \frac{2(1 - 3^n)}{1 - 3}[/tex]
[tex] 6,560 = \frac{2(1 - 3^n)}{-2} [/tex]
[tex] 6,560 = \frac{1 - 3^n}{-1} [/tex]
Multiply both sides by -1
[tex] -6,560 = 1 - 3^n [/tex]
Subtract 1 from both sides
[tex] -6,560 - 1 = - 3^n [/tex]
[tex] -6,561 = - 3^n [/tex]
[tex] 6,561 = 3^n [/tex]
Evaluate
[tex] 3^8 = 3^n [/tex]
3 cancels 3
[tex] 8 = n [/tex]
The value of n = 8

Answer:
6 ft
Step-by-step explanation:
The building height of 100 ft is 4 times the shadow length of 25 ft. At the same ratio, the person's height is 4 times the 1.5 ft shadow length, so is ...

Less than 51% of workers got their job through networking. Express the null and alternative hypotheses in symbolic form for this claim (enter as a percentage). H0 : p H1 : p
Use the following codes to enter the following symbols:
≥≥ enter >=
≤≤ enter <=
≠≠ enter !=
Answer:
Null Hypothesis, [tex]H_0[/tex] : p [tex]\geq[/tex] 51%
Alternate Hypothesis, [tex]H_A[/tex] : p < 51%
Step-by-step explanation:
We are given that less than 51% of workers got their job through networking. We have to express the null and alternative hypotheses in symbolic form for this claim.
Let p = population proportion of workers who got their job through networking
So, Null Hypothesis, [tex]H_0[/tex] : p [tex]\geq[/tex] 51%
Alternate Hypothesis, [tex]H_A[/tex] : p < 51%
Here, the null hypothesis states that greater than or equal to 51% of workers got their job through networking.
On the other hand, the alternate hypothesis states that less than 51% of workers got their job through networking.
Hence, this is the appropriate hypothesis that can be used.
The productivity of workers at a shoe factory (in pairs of shoes per hour) can be modeled using the function p(h) = -2/7h + 5, where h is the number of hours. If a worker must create at least 3 pairs of shoes per hour for the company to be profitable, how long should the worker's shift be?
Answer:
no more than 7 hours
Step-by-step explanation:
You want p(h) ≥ 3, so ...
p(h) ≥ 3
-2/7h +5 ≥ 3
2 ≥ 2/7h . . . . . . add 2/7h -3
7 ≥ h . . . . . . . . . multiply by 7/2
The worker's shift should be 7 hours or less.

Answer:
f(x)=2x-2 with =( -1, 4)
f(x)=2(x^2) -2 with (-1,0)
f(x)=2√(x-2) with (2,0)
Step-by-step explanation:
f(x)=2x-2
(2,0)
0=2(2)-2=2 0=2
(-1,-4)
4=2(-1)-2=-4 -4 = -4 f(x)=2(x^2) -2
(2,0)
0=2(2^2)-2=6 0=6
(-1,0)
0=2(-1^2)-2=0 0=0 f(x)=2√(x-2) (2,0)
0=2√(2-2)=0 0=0
The function f ´( x ), which would be read `` f -prime of x '', means the derivative of f ( x ) with respect to x .
What is f(x) ?A function called f is defined by the notation y=f(x). This should be understood as "y is a function of x." The input value, or independent variable, is represented by the letter x. The output value, also known as the dependent variable, is denoted by the letter y, or f(x).
f(x)=2x-2\s(2,0)
0=2(2)
-2=2 0=2
(-1,-4)
4=2(-1)-2=-4 -4 = -4 f(x)=2(x^2) -2\s(2,0) (2,0)
0=2(2^2)
-2=6 0=6\s(-1,0)
0=2(-1^2)
-2=0 0=0 f(x)=2 √(x-2) (2,0) (2,0)
0=2√(2-2)=0 0=0
The phrase "f (x)" denotes a formula with x serving as its input variable. Not "multiply f and x," though! Never try to "multiply" the function name with its parenthesized input and avoid embarrassing yourself by pronouncing (or thinking of) "f (x)" as being "f times x".
For the functions f(x)=−9x^2+9 and g(x)=8x^2+9x, find (f+g)(x) and (f+g)(−1)
Answer:
f(x) = - 9x² + 9
g(x) = 8x² + 9x
To find (f+g)(x) add g(x) to f(x)
That's
(f+g)(x) = -9x² + 9 + 8x² + 9x
Group like terms
(f+g)(x) = - 9x² + 8x² + 9x + 9
(f+g)(x) = - x² + 9x + 9To find (f + g)(- 1) substitute - 1 into (f+g)(x)
That's
(f + g)(- 1) = -(-1)² + 9(-1) + 9
= - 1 - 9 + 9
= - 1Hope this helps you
let g(x) = 2x and h(x) = x^2 +4. evaluate (g• h) (3)
Answer:
(g• h) (3) = 26Step-by-step explanation:
g(x) = 2x
h(x) = x² + 4
To find (g• h) (3) first find ( g • h)(x)
To find ( g • h)(x) substitute h(x) into every x in g(x)
That's
( g • h)(x) = 2( x² + 4)
( g • h)(x) = 2x² + 8
Now substitute 3 into ( g • h)(x)
(g• h) (3) = 2(3)² + 8
= 2(9) + 8
= 18 + 8
(g• h) (3) = 26Hope this helps you
A cylindrical package to be sent by a postal service can have a maximum combined length and girth (perimeter of a cross section) of 141 inches. Find the dimensions of the package of maximum volume that can be sent. (The cross section is circular.)
Answer:
Length = 47 in
Radius = 47/π in
Step-by-step explanation:
Let 'h' be the length of the package, and 'r' be the radius of the cross section.
The length and girth combined are:
[tex]L+G=141=h+2\pi r\\h=141-2\pi r[/tex]
The volume of the cylindrical package is:
[tex]V=A_b*h\\V=\pi r^2*h[/tex]
Rewriting the volume as a function of 'r':
[tex]V=\pi r^2*h\\V=\pi r^2*(141-2\pi r)\\V=141\pi r^2-2\pi^2 r^3[/tex]
The value of 'r' for which the derivate of the volume function is zero yields the maximum volume:
[tex]V=141\pi r^2-2\pi^2 r^3\\\frac{dV}{dr}=282\pi r-6\pi^2r^2=0\\ 6\pi r=282\\r=\frac{47}{\pi} \ in[/tex]
The length is:
[tex]h=141-2\pi r=141-2\pi*\frac{47}{\pi}\\h=47\ in[/tex]
The dimensions that yield the maximum volume are:
Length = 47 in
Radius = 47/π in

What is transformation on the graphs?Graph transformation is the process by which an existing graph, or graphed equation, is modified to produce a variation of the proceeding graph. It's a common type of problem in algebra, specifically the modification of algebraic equations.
here, we have,
Let the functions f(x) and g(x) be two real functions.
And g (x) = f (x) + k, where k is real numbers.
The function can be sketched by shifting f (x), k units vertically.
The value of k can find the direction of shift:
if k > 0, the base graph shifts k units up, and
if k < 0, the base graph shifts k units down.
Given that ,
the parent function is g(x) = x².
To find the transformed function F(x):
The function's diagram is in the opposite direction.
That means the function is -x².
And the function is shifted 3 units down vertically.
From the definition the required function is,
F(x) = -x² - 3.
Therefore, F(x) = -x² - 3.

A hypothesis regarding the weight of newborn infants at a community hospital is that the mean is 6.6 pounds.
A sample of seven infants is randomly selected, and their weights at birth are recorded as:
9.0, 7.3, 6.0, 8.8, 6.8, 8.4, and 6.6 pounds.
If Alpha = 0.05,
1. What is the critical t-value?
2. What is the decision for a statistically significant change in average weights at birth at the 5% level of significance?
Answer:
1. Critical value t=±2.447
2. The null hypothesis is failed to be rejected.
At a significance level of 0.05, there is not enough evidence to support the claim that the birth weight significantly differs from 6.6 lbs.
Step-by-step explanation:
This is a hypothesis test for the population mean.
The claim is that the birth weight significantly differs from 6.6 lbs.
Then, the null and alternative hypothesis are:
[tex]H_0: \mu=6.6\\\\H_a:\mu\neq 6.6[/tex]
The significance level is 0.05.
The sample has a size n=7.
The sample mean is M=7.56.
As the standard deviation of the population is not known, we estimate it with the sample standard deviation, that has a value of s=1.18.
The estimated standard error of the mean is computed using the formula:
[tex]s_M=\dfrac{s}{\sqrt{n}}=\dfrac{1.18}{\sqrt{7}}=0.446[/tex]
Then, we can calculate the t-statistic as:
[tex]t=\dfrac{M-\mu}{s/\sqrt{n}}=\dfrac{7.56-6.6}{0.446}=\dfrac{0.96}{0.446}=2.152[/tex]
The degrees of freedom for this sample size are:
[tex]df=n-1=7-1=6[/tex]
For a two-tailed test with 5% level of significance and 6 degrees of freedom, the critical value for t is ±2.447.
As the test statistic t=2.152 is under 2.447 and over -2.447, it falls in the acceptance region, so the effect is not significant. The null hypothesis is failed to be rejected.
At a significance level of 0.05, there is not enough evidence to support the claim that the birth weight significantly differs from 6.6 lbs.
Sample mean and standard deviation calculations:
[tex]M=\dfrac{1}{n}\sum_{i=1}^n\,x_i\\\\\\M=\dfrac{1}{7}(9+7.3+6+. . .+6.6)\\\\\\M=\dfrac{52.9}{7}\\\\\\M=7.56\\\\\\s=\sqrt{\dfrac{1}{n-1}\sum_{i=1}^n\,(x_i-M)^2}\\\\\\s=\sqrt{\dfrac{1}{6}((9-7.56)^2+(7.3-7.56)^2+(6-7.56)^2+. . . +(6.6-7.56)^2)}\\\\\\s=\sqrt{\dfrac{8.32}{6}}\\\\\\s=\sqrt{1.39}=1.18\\\\\\[/tex]
Quantum numbers arise naturally from the mathematics used to describe the possible states of an electron in an atom. The four quantum numbers, the principal quantum number (n), the angular momentum quantum number (â), the magnetic quantum number (mâ), and the spin quantum number (ms) have strict rules which govern the possible values. Identify allowable combinations of quantum numbers for an electron. Select all that apply.
n = 4, â= 0, mâ= 1, ms= 1/2
n = 3, â= â2, mâ= â1, ms= â1/2
n = 5, â= 3, mâ= 1, ms= 1/2
n = 3, â= 3, mâ= 0, ms= 1/2
n = 2, â= 1, mâ= 0, ms= 0
n = 3, â= 2, mâ= â1, ms= 1/2
Answer:
n = 3, â= 2, mâ= â1, ms= â1/2
n = 5, â= 3, mâ= 1, ms= 1/2
Step-by-step explanation:
Quantum numbers are used to describe an electron in an atom. According to Pauli exclusion theory, no two electrons in an atom has the same value for all four quantum numbers.
For, n = 3, â= 2, mâ= â1, ms= â1/2
The n=3 level can have values of azimuthal quantum number 0,1,2
Where l=2, the values of the magnetic quantum number are -2,-1,0,1,2
The spin quantum number must be ±1/2
Hence this option is a possible combination.
For n = 5, â= 3, mâ= 1, ms= 1/2
The n=5 level may have azimuthal quantum numbers 0,1,2,3.
For l=3, the values of magnetic quantum number are; -3,-2,-1,0,1,2,3
The spin quantum number must be ±1/2
Hence this option is a possible combination.
Trish conducts an analysis which shows that the level of alcohol consumption affects reaction times more when a person is sleep-deprived than when a person is well-rested. This is an example of ______.
a. interaction
b. confounding
c. bias
d. main effect
Answer:
a. interaction
Step-by-step explanation:
In statistics, interaction occurs when the effect of one variable depends on the value of another variable.
In this case, Trish's analysis shows that the effect of alcohol consumption in a persons reaction time also depends on that person's quality of sleep, highlighting a clear case of interaction.
A sum lent out at simple interest becomes rs4480 in 3 years and rs 4800 in 5years.find the rate of interest
Answer: rate = 4%
Step-by-step explanation:
SI = 4800 - 4480 = 320 for two years
For 1 year, it is 320/2 = 160
For 5 years, it is 160 * 5 = 800
Principal = Amount -SI
P = 4800 - 800 = 4000
SI = prt / 100
800 = (4000 * r * 5) / 1000
r = 800 * 100 / 4000 * 5
r = 4%
Answer:
Rate of intrest = 4%
Step-by-step explanation:
Short forms
Simple intrest=SI Year= Y Rate= r
SI= 4800-4480
= 320
1 year= 320/2 = 160
5year= 160 x 5
= 800
P= Amount-SI
P= 4800-800
= 4000
SI=PRT/100
800=(4000 X r X 5)/1000
r=800 x 100/4000 x 5
r= 4%

Scott has verified that the window is a rectangle. Side AB is half of the length of side AC. If the perimeter of the window is 120 ft., what are the lengths of side AB and side AC?
Answer:
AB = 20 ft
AC = 40 ft
Step-by-step explanation:
==>Given:
Rectangular window ABCD, where,
side AB = ½ of side AC
Perimeter = 120ft
==>Required:
Length of side AB and side AC
==>Solution:
Let AB = x
If x = ½ of AC
AC = 2x
Perimeter = 2(AB + AC)
Thus,
120 = 2(x+2x)
120 = 2(3x)
120 = 6x
Divide both sides by 6 to solve for x
120/6 = x
20 = x
AB = x = 20 ft
AC = 2x = 2(20) = 40ft

Step-by-step explanation:
The measure of angle 1 is (10 x + 8) degrees and the measure of angle 3 is (12 x minus 10) degrees. 2 lines intersect to form 4 angles. From top left, clockwise, the angles are 1, 2, 3, 4. What is the measure of angle 2 in degrees?
Answer:
Measure of angle 2 = 82°
Step-by-step explanation:
m∠1 = (10 x + 8)°
m∠3 = (12 x - 10)°
2 lines are said to intersect to form 4 angles. And the labelling of the angles was done starting from top left, clockwise: the angles are 1, 2, 3, 4.
Find attached the diagram obtained from the given information.
Vertical angles are angles opposite each other when two lines intersect. As such, they are equal to each other.
Considering our diagram
m∠1 = m∠3
m∠2 = m∠4
Sum of all four angles firmed = 360° (sum of angles at a point)
m∠1 +m∠2 + m∠3 + m∠4 = 360°
m∠1 = m∠3
(10 x + 8)°= (12 x - 10)°
10x-12x = -10-8
-2x = -18
x= 9°
Also m∠2 = m∠4, let each equal to y
(10 x + 8)°+ y + (12 x - 10)° + y = 360
10x + 12x - 10 +8 +2y = 360
Insert value of x
22(9) -2 + 2y = 360
2y = 360-196
2y = 164
y = 82°
m∠2 = m∠4 = y = 82°
Measure of angle 2 = 82°
Answer:
2 = 82°

Step-by-step explanation:
2a -a + 1 =
x + y + x + 2 =
2(x + 4) + 2x =
3x + 2(x - 2) =
Answer:
Step-by-step explanation:
Please, share the instructions that come with each problem. Thanks.
2a -a + 1 = can be simplified to a + 1.
x + y + x + 2 = cannot be simplified.
2(x + 4) + 2x =
3x + 2(x - 2) = can be expanded and then simplified:
3x + 2x - 4 = 5x - 4
