Answer:

The similarity is they are using tools to help them make the lines, but the differences are they are using different tools to make different lines. While 1 of the tools is similar to the other

Step-by-step explanation:

Let height be x, then radius is also x.

We know that,

C.S.A. = 2πrh

=> 308cm² = 2πxx

=> 308cm² = 2πx²

=> 308cm² = 2(22/7)x²

=> 308cm² = (44/7)x²

=> 308cm² × (7/44) = x²

=> 2156/44 cm² = x²

=> 49cm² = x²

=> √(49cm²) = x

=> 7cm = x

So, height and radius are 7cm each.

x(x-2)+5(x-2)

X^2–2x+5x-10

X^2+3x-10

Answer: x^2-2x+5x-10

Step-by-step explanation:

multiply x1 by x2 which equals x^2 then x1 by -2 which is -2x then multiply 5 by x2 which is positive 5x then multiply 5 by -2 which is -10

Answer:

The correct answer is A.

Step-by-step explanation:

From the picture you provided, you choose option A, f(x) = x^7 - x^3 - 3x^2 + 3 . Hope that helped :)

The functions that could have created this graph is f(x) = x⁷-x³-3x²+3

A function is an equation for which any x that can be put into the equation will produce exactly one output such as y out of the equation.

Given is a graph, we need to find its equation,

So, the graph is U-shaped, therefore, the leading coefficient is, a > 0

also, the graph does not have a zero at the origin,

The function which could possibly create the graph is the option; A.

F(x) = x⁷-x³-3x²+3

The leading coefficient is 1 > 0

The function has no factors of x = 0

The function has a linear factor.

Hence, the functions that could have created this graph is f(x) = x⁷-x³-3x²+3

Answer:

the slope is 2

Step-by-step explanation:

to find slope all you need to do is look at the places where the line and the graph intersect. you should be able to find atleast 2 places. Once you have done that, count up how ever many spaces it is until you are on the same line with the place where the line intersects with the graph remember that number in your head, then could left or right until you are on top of the other place where it intersects, remember that number. In this case I counted 2 spaces up and 1 space to the left which gave me 2/1 which is 2

hope this helps. have a good day!

Answer:

Results are below.

Step-by-step explanation:

1. First, we need to calculate the Future Value:

FV= {A*[(1+i)^n-1]}/i

A= quarterly deposit

n= 10*4= 40

i= 0.12/4= 0.03

FV= {4,000*[(1.03^40) - 1]} / 0.03

FV= $301,605.04

Now, the present value:

PV= FV/(1+i)^N

PV= 301,605.04/(1.03^40)

PV= $92,459.09

2. First, we need to calculate the value of the first year of college:

FV= PV*(1+i)^n

FV= 24,000*(1.04^3)

FV= $26,996.74

Now, the quarterly payments:

FV= {A*[(1+i)^n-1]}/i

A= quarterly deposit

Isolating A:

A= (FV*i)/{[(1+i)^n]-1}

i= 0.08/4= 0.02

n= 3*4= 12

A= (26,996.74*0.02) / [(1.02^12) - 1]

A= $2,012.87

Answer:

The answer is 12

Step-by-step explanation:

You have to divide 5 and 60 or you can multiply by 5 until you get to 60.

Answer: B) [-0.0332,0.1332]

Step-by-step explanation: Confidence Interval is an interval where we can be a percentage sure the true mean is.

The confidence interval for a difference in population proportion is calculated following these steps:

First, let's find population proportion for each population:

[tex]p_{1}=\frac{30}{120}=0.25[/tex]

[tex]p_{2}=\frac{32}{160}=0.2[/tex]

Second, calculate standard deviation for each proportion:

[tex]\sigma_{1}=\sqrt{\frac{0.25(0.75)}{120} } = 0.0395[/tex]

[tex]\sigma_{2}=\sqrt{\frac{0.2(0.8)}{160} } = 0.0316[/tex]

Now, we calculate standard error for difference:

[tex]SE=\sqrt{\sigma_{1}^{2}+\sigma_{2}^{2}}[/tex]

[tex]SE=\sqrt{0.0395^{2}+0.0316^{2}}[/tex]

SE = 0.0505

The z-score for a 90% CI is 1.645.

Then, confidence interval is

[tex]p_{1}-p_{2}[/tex] ± z-score.SE

[tex]0.25-0.2[/tex] ± [tex]1.645(0.0505)[/tex]

0.05 ± 0.0831

The limits of this interval are:

inferior: 0.05 - 0.0831 = [tex]-0.0332[/tex]

superior: 0.05 + 0.0831 = 0.1332

The 90% confidence interval for the difference in the population proportion of pit pulls and golden retrievers is [tex][-0.0332,0.1332][/tex].
