Function A and Function B are linear functions. Compare the two functions and choose all that are correct.
Answers
Answer:
2 .The slope of Function A is less than the slope of Function B
A graph of Function A shows it has a y-intercept of 4, the same as that of Function B. (Statements 3 and 4 are not correct.)
The slope of Function A is 2, which is less than the slope of 3 that Function B has. (Statement 2 is correct; statement 1 is not.)
_____
More detailed working
The slope of Function A can be figured easily between the points with x-values that differ by 1:
m = (y3 -y2)/(x3 -x2) = (24-22)/(10-9) = 2/1 = 2 . . . . . Fun A has slope of 2.
The slope of Function B is the coefficient of x in the equation: 3.
__
The y-intercept of Function A can be found starting with point-slope form:
y -22 = 2(x -9)
y = 2x -18 +22
y = 2x +4 . . . . . . . slope-intercept form
The intercept of +4 is the same as that of Function B.

Solve for (n): 110 = n/10
Answers
Answer:
n = 1100
Step-by-step explanation:
Isolate the variable, n. Note the equal sign, what you do to one side, you do to the other. Multiply 10 to both sides of the equation:
110 = n/10
(110) * 10 = (n/10) * 10
n = 110 * 10
n = 1100
1100 is your answer for n.

Explanation:
The equation for surface area of a cylinder is; a=2pirh+2pir^2
So a=2 x pi x 3 x 10 + 2 x pi x 3^2
Then follow order of operations, so start with exponent
So a= 2 x pi x 3 x 10 + 2 x pi x 9
Then multiplication, but leave pi since out answer will be in pi
So a = 2 x pi x 30 + 2 x pi x 9
Next multiply 2 x 30 and 2x9
a= pi x 60 + 18
Add
a= 78 pi

The lines graphed below show the amounts of water in two tanks as they
were being filed over time.
Which tank shows a proportional relationship between the amount of
water, in gallons, and the time, in minutes?
Answers
Answer:
Tank B
Step-by-step explanation:
Proportional relationships are relationships between two variables with equivalent ratios. For a proportional relationship, one variable is always a constant value times the other. A line is a proportional relationship if it starts from the origin, but if it does not start from the origin, it is not proportional.
From the two tanks, we can see that tank A have a y intercept whereas tank B starts from the origin. Therefore tank B shows a proportional relationship.

A model car is built on a 1:16 scale
If the wheelbase on the actual car is 186 inches, what is the wheelbase on the model? Give your answer as a decimal. Do not round and do not include the units.
Answers
Answer:
11.625inches
Step-by-step explanation:
If a model car is built on a 1:16 scale and the length of actual car is 186inches
16inches = 1
186inches = x
16* x = 186
x = 186/16
x = 11.625
hence the wheel base of the model is 11.625inches

It takes an older pump 4 times as long to drain a certain pool as it does a newer pump. Working together, it takes the two pumps 3 hours to drain the pool. How
long will it take the newer pump to drain the pool working alone?
Do not do any rounding.
Answers
Answer:
New pump = 3.75 hours
Old pump = 15 hours
Step-by-step explanation:
Let :
Time taken by newer pump = x hrs
Time taken by older pump = 4x hrs
Time taken when working together = 3 hours
Drain rate :
Newer pump = 1/x
Older pump = 1/4x
Combined = 1/3
Hence :
Newer pump rate + older pump rate = combined rate
1/x + 1/4x = 1/3
Take the lcm
(4 + 1) / 4x = 1/3
Cross multiply
5 * 3 = 4x
15 = 4x
x = 15/4
x = 3.75
The old pump will take :
4x = 4 * 3.75 = 15 hours

Answers
Answer:
"0.9739" is the correct answer.
Step-by-step explanation:
The given values are:
The ratio of true to false effects,
= 0.07
The power of study,
= 0.8
Alpha level,
= 0.05
Now,
The percentage of effects proved as significant will be:
= [tex]0.8\times \ 70 \ percentage[/tex]
= [tex]0.56[/tex]
0r,
= [tex]56[/tex]%
The percentage of false effects will be:
= [tex]0.05\times 30 \ percent[/tex]
= [tex]0.015[/tex]
or,
= [tex]1.5[/tex]%
The total effects will be:
= [tex]56+1.5[/tex]
= [tex]57.5[/tex]%
hence,
The probability that this effect is real will be:
= [tex]\frac{56}{57.5}[/tex]
= [tex]0.9739[/tex]

Answer:
x=35
y=72.5
Step-by-step explanation:
Answer:
x=35 , y=72.5
Step-by-step explanation:
I'm not amazing at explaining but x is obviously 35 as its across from it and looks like it's the same angle, we'll be able to test this when we figure out y. Both of the y values are the same number so you just need to figure out
2y + 35 = 180
Minus 35 from both sides
2y = 145
Then we can divide 2 from both sides
y = 72.5
Then we test for x
2y + x = 180
Plug in y
145 + x = 180
Minus 145 from both sides
x= 35

interest rate is 8.9%?
A. 0.74
B. 0.74
C. 0.0074
D. 0.0089
Answers
Answer:
c
Step-by-step explanation:
<3
The monthly rate of interest is 0.0074. Therefore, option C is the correct answer.
What is the rate of interest?An interest rate tells you how high the cost of borrowing is, or high the rewards are for saving. So, if you're a borrower, the interest rate is the amount you are charged for borrowing money, shown as a percentage of the total amount of the loan.
The given rate of interest is 8.9%.
The monthly payment formula is M = Pr(1+ r)ⁿ/(1+ r)ⁿ - 1
Here, rate of interest
= 8.9%/12
= 0.089/12
= 0.0074
Therefore, option C is the correct answer.

Find the volume of a pyramid with a square base, where the area of the base is
12.2 m² and the height of the pyramid is 12.3 m. Round your answer to the nearest
tenth of a cubic meter.
Answers
Answer:
50.0 cm²
Step-by-step explanation:
Applying
Volume of a pyramid (V) = 1/3×Area of the base(A')×Heigth(H)
A= 1/3A'h.................... Equation 1
A' = Area of the base, h = height of the pyramid
From the question,
Given: A' = 12.2 m², h = 12.3 m
Substitute these values into equation 1
A = 1/3(12.2×12.3)
A = 50.02
A = 50.02 cm²
A = 50.0 cm²

Scalene Triangle
Step.-by-step explanation:
Calculate the lengths of the sides:
Side 1 = √((4-3)^2+(7-2)^2) = √26.
Side 2 = √((6-7)^2+(5-4)^2) = √2.
Side 3 = √((6-2)^2+(5-3)^2) = √20.
So each side is different in length and so its a scalene triangle.

A UW Madison professor is interested in learning about the variance of grades for university students. The professor gathers the sample variance for a random sample of 50 students. From past experience, the professor knows that the population of students is normally distributed. The sample variance that is collected is equal to 80. The professor would like to infer at the 1% significance level that the population variance is less than 100.
a. State the appropriate null and alternative hypothesis.
b. What is the correct test statistic?
c. What is the conclusion of the test?
d. What would be the effect if the professor increased the sample size?
Answers
Answer:
A) H0 : μ = 100
H1 : μ < 100
B) 39.2
C) We fail to reject null hypothesis
D) If the professor increases the sample size the value of the test statistic will increase .
Step-by-step explanation:
sample variance ( s ) = 80
sample size = 50
At ∝ = 0.01 population variance ( σ ) < 100
a) Hypothesis
H0 : μ = 100 ( Null hypothesis )
H1 : μ < 100 ( Alternate hypothesis )
b) Determine The correct test statistic
x^2 = ( n-1 ) * s^2/σ^2
= ( 49 ) * 80^2 / 100^2
= 39.2
C) Determine the conclusion of the test
The P-value = 0.1596 ( calculated )
The conclusion of the test is that we fail to reject null hypothesis given that
P-value ( 0.1596 ) > ∝ ( 0.01 )
D) If the professor increases the sample size the value of the test statistic will increase .
