Answer:
C
Step-by-step explanation:
In slope intercept form y=mx+b
m is your rate of change/ slope
since the slope is +5
This means that your rate of change, in this case elevation, is 5 feet per minute.
As for b which is your y intercept, the -30 can be represented by the point (0,-30) on a graph it would be -30ft below the x axis. Meaning that if the diver lets say is the point he is 30 feet below sea level and acsending at a rate of 5 feet per minute.

Answer:
1. False
2. False
3. True
Step-by-step explanation:
1. It fails the 'Vertical Line Test.' Draw a line through the center of the relation and see if the line passes through the graph more than once. It does, therefore it fails the test. Meaning it is not a function.
2. Domain (x) is all the x-values in the equation, the relation only contains the x-values x>0 and x<7 (0 - 7). Meaning it does not contain all real numbers.
3. The range (y) contains negative numbers because the relation is partially in the 4th quadrant, meaning it MUST contain a negative y-value.

You are a personnel director and are interested in predicting the Number of Shares of Company Stock (Y) using the Number of Years Employed with the Company (X). You randomly selected 8 employees and found that the average number of shares is 525 and the average number of years employed is 22.5. If the slope (b1) is 20.0, what is the least squares estimate of the intercept (b0)?
a. 25.0
b. 75.0
c. 40.0
d. 80.5
e. None of these are correct
Answer:
b. 75.0
Step-by-step explanation:
Calculation for the least squares estimate of the intercept (b0)
Using this formula
Intercept (b0) least squares estimate=[Shares average number-(Slope (b1)*Average number of years employed)]
Let plug in the formula
Intercept (b0) least squares estimate=[525-(20.0*22.5)]
Intercept (b0) least squares estimate=525-450
Intercept (b0) least squares estimate=75.0
Therefore the least squares estimate of the intercept (b0) will be 75.0

Explaining the concept:
We know that:
√ab = √a * √b
Using this concept, we will simplify the given expression and solve it

The cost of student tickets at a movie theater can be
equation: C = $5.50x, where C is the cost and x is the number of student
tickets. Which statements are true about this situation? Select each correct
statement.
A. The constant of proportionality is $5.50.
B. The unit rate is $2.25.
C. Two movie tickets cost $11.00.
A - Correct
The proportionality constant is the number that associates the two different quantities. In this case, the cost is 5.5 times the number of tickets, therefore, it is the constant of proportionality between the cost and the number of students.
B- Incorrect
If you plug in x=1, you get the cost for exactly one ticket. In this case, C(1)=5.5, so the unit rate is 5.5
C- Correct
If you plug in x=2, you get the cost for two tickets. Therefore C(2) = 5.5x2;
C(2)= 11
So the cost of two tickets is $11.00

Defects in computer hard-drives will usually render the entire computer worthless. For a particular model, the percent defective in the past has been 1%. If a sample size of 400 is taken, what would the 95.5% lower control chart limit be?
Answer:
0.00005
Step-by-step explanation:
We have the average fraction defective as p = 1%
= 0.01
N = 100
Then 95.5% deviation = 2σ
From there we have,
σ = √p*(1-p)/n
When we input these values, into the formula, we will have
σ = √0.01(1-0.01)/100
= √0.01(0.99)/100
= √0.000099
= 0.00995
The LCL = p - 2σ
= 0.01 - 0.00995
= 0.00005
lower control chart limit be is 0.00005
The 95.5% lower control chart limit be is 0.0005.
Given,
The average fraction percent in the past defective as p = 1% = 0.01
Sample size N = 400
Then ,
According to the question ,
95.5% deviation = 2x
We have,
x = [tex]\frac{\sqrt{p (1-p)} }{n}[/tex]
We put these values, into the formula,
x = [tex]\frac{\sqrt{0.01 ( 1 - 0.01) } }{400}[/tex]
= [tex]= \frac{\sqrt{(0.01) (0.99)} }{400}[/tex]
= [tex]\frac{0.99}{400}[/tex]
= 0.0000245
The LCL = p - 2x
= 0.01 - 0.0000245
= 0.00005
The Lower control chart limit be is 0.00005

The missing term is A-2. The sample size would be 6.
B.
The missing term is C-2. The sample size would be 8.
C.
The missing term is C-2. The sample size would be 9.
D.
The missing term is B-2. The sample size would be 12.
Answer:
It is A
Step-by-step explanation:
The answer is A. The missing term is A-2. The sample size would be 6.
a. To answer the question, we need to know what sample space is.
What is a sample space?A sample space is the total number of possible outcomes of an event.
Now, since there are Doors 1, 2 and 3 and Keys A, B and C. The sample space is
Key A: A-1, A-2, A-3
Key B: B-1, B-2, B-3
Key C: C-1, C-2, C-3
So, the missing item is A-2.
b.
The sample size would be 6.
To answer the question, we need to know what sample size is.
What is sample size?The sample size is the size of the sample space.
If there were two doors instead of 3, the sample size would be since we have 2 doors and 3 keys. The sample size is 2 × 3 = 6.
So, the sample size would be 6.
So, the answer is A. The missing term is A-2. The sample size would be 6.

Find the value of an investment of $15,000 for 13 years at an annual interest rate of 4.55% compounded continuously.
Answer:
A = $27100.5
Step-by-step explanation:
We are given;
Principal: P = $15,000
Interest rate: r = 4.55% = 0.0455
Time in years: t = 13 years
The formula for the value of the investment after t years of continuous compounding is;
A = P(e^(rt))
A = 15000(e^(0.0455 × 13))
A = 15000 × 1.8067
A = $27100.5

The total cost to buy pizzas from Mrs. miss holiday party can be found using the function C(x)=10+3.50x, where X is the number of pizza bought. She wants to order at least 5 pizzas but no more than 9 pizzas for class. Is this a continuous or discreet relationship?
What is the domain and what is the range of the situation?
Answer:
We have the equation:
C(x) = 10 + 3.50*x
x represents the number of pizzas she buys, x only can take whole values, so we must have x ∈ Z
This means that this relation is discrete because there are only some values of x avaible, and thus there will be only some values of C(x) avaible.
She wants to buy at least 5 pizzas, and no more than 9, then the domain will be:
5 ≤ x ≤ 9
Or we could write the domain as:
{5, 6, 7, 8, 9}
This means that the possible costs will be:
C(5) = 10 + 3.50*5 = 27.50
C(6) = 10 + 3.50*6 = 31
C(7) = 10 + 3.50*7 = 34.5
C(8) = 10 + 3.50*8 = 38
C(9) = 10 + 3.50*9 = 41.50
Then the range is:
{27.50, 31, 34.5, 38, 41.50}

It's the third option because if you put a piece of paper in the corner its a lil more than 90 degrees, so it wouldn't be B (there's a little more white space left). And it obviously wouldn't be A because that's self explanatory, lol.

How many cubes with edge length of ⅓ inch are needed to fill a rectangular prism that is 3 inches by 1 inch by 1 ⅓ inches?
Answer:
We need 108 cubes to fill the rectangular prism
Step-by-step explanation:
We are given the dimensions of a cube with an edge length of 1/3 inch.
A rectangular prism is to be filled out with those cubes. The dimensions of the prism are 3 inches x 1 inch x 1 1/3 inches.
The fraction 1 1/3 is expressed as:
[tex]1\frac{1}{3}=1+\frac{1}{3}=\frac{4}{3}[/tex]
We need to know how many cubes fit in each dimension. It can be found by dividing them by their edge length:
[tex]\displaystyle \frac{3}{\frac{1}{3}}=3*3 =9[/tex]
[tex]\displaystyle \frac{1}{\frac{1}{3}}=1*3 =3[/tex]
[tex]\displaystyle \frac{\frac{4}{3}}{\frac{1}{3}}=\frac{4}{3}*3=4[/tex]
Now we multiply the number of cube per dimension:
9*3*4=108
We need 108 cubes to fill the rectangular prism
when you multiply 2/3 by a fraction less than one,how does the product compare to the factors?
Answer:
The product is less than either of the factors. Multiplying a number < 1 with 2/3 another number < 1, will give a fraction of a fraction, and part of a fraction is an even smaller fraction. Another way of looking at it: Fractions less than one have numerators smaller than their denominators. When multiplying fractions, you multiply across, so multiplying two fractions that are both less than one will always give a numerator much smaller than the denominator, and a larger denominator makes for a smaller number. I hope this helps, but if you have questions, ask.
