Answer:

345 + C

Step-by-step explanation:

From the first sentence, we know that Mike moved a total of:

           345chairs

In the second sentence, we know that Gavin moved C more chairs than Mike;

 Mathematically;

Number of chairs moved by Galvin;

                    345 + C

Therefore, in terms of C, the number of chairs moved by Gavin is:

              345 + C

Answer:

92°

Step-by-step explanation:

(2x - 2)° = x ° + 45°

(2x - 2 - x)° = 45°

(x - 2)° = 45°

x - 2 = 45

x = 45 + 2

x = 47

(2x - 2)° = (2*47 - 2)° = (94 - 2)* = 92°

Answer: 10%

Step-by-step explanation:

X intercept: (-2,0)

Y intercept: (0,5)

Have a wonderful and blessed day!

Answer:

The x-intercept is 2.

The y-intercept is 5.

Step-by-step explanation:

The x-intercept is basically finding what the value of x when y is 0; y-intercept is vise-versa.

The format it is currently in is not in y=mx+b form which makes you unable to put on a graph...HOWEVER, YOU ACTUALLY CAN!

You goal for these type of questions is to isolate y by itself.

[tex]-20x+8y=40\\8y=20x+40\\y=2.5x+5[/tex]

Your equation has been converted into y=mx+b which now can be used to easily find the x and y intercepts.

You can either look at a graph and find the x and y intercepts or do it algebraically.

Since, "x-intercept is basically finding what the value of x when y is 0", we plug in y with 0.

Solve for X-Intercept:

[tex]0=2.5x+5\\-5=2.5x\\-2=x[/tex]

X-Intercept is -2

Solve for Y-intercept:

[tex]y=2.5(0)+5\\y=5[/tex]

Y-Intercept is 5

Answer:

(2x+5)(x+1)

Step-by-step explanation:

We look for two numbers which multiply to 10(that is 2×5) and add to 7. Our numbers are 2and 5

2×5=10 and 2+5=7

Therefore we have

(2x²+2x)+(5x+5)

2x(x+1)+5(x+1)

(2x+5)(x+1)

Answer:

Option (3)

Step-by-step explanation:

Formula to get the surface area of a sphere is,

Surface area of a sphere = 4πr²

Here 'r' = Radius of a sphere

Since, r = 9 units and π = 3.14

Surface area of the sphere = 4(3.14)(9)²

                                             = 1017.36 square ²units

Therefore, Option (3) will be the correct option.

A=3.14*6^2

6*6=36

[tex]B.30.96\ mm^2[/tex]

Step-by-step explanation:

[tex]We\ are\ given\ that,\\Side\ of\ the\ square=12\ mm\\Diameter\ of\ the\ circle=12\ mm\\First,\\Lets\ consider\ the\ square.\\As\ the\ area\ of\ a\ square=n^2\\The\ area\ of\ the\ given\ square=(12\ mm)^2\\Hence,\\The\ area\ of\ the\ given\ square=144\ mm^2\\Now,\\Lets\ consider\ the\ circle.\\As\ the\ diameter\ of\ the\ circle=12\ mm\\Radius\ of\ the\ circle=12/2=6\ mm\\Hence,\\As\ the\ Area\ of\ a\ circle=\pi r^2\\Area\ of\ the\ given\ circle=3.14*6*6\\[/tex]

As we see the only option is N = 2^3 = 8 and M = 3^2 = 9

Answer:

92

Step-by-step explanation:

M is the prime number 23 (two factors are 1 and 23) and N is the square number 4 (factors are 1, 2, and 4). 23 x 4= 92

1) The proportion of the sample that has HIV is 0.16. 2) The randomly selected numbers represent the HIV status of the simulated residents.

1. The proportion of the sample that has HIV is 20 / 125 = 0.16.

2. The randomly selected numbers represent the HIV status of the simulated residents. We picked 125 of them because that is the sample size of the actual study.

We can assign the numbers 1 to 13 to represent the simulated residents who have HIV. This is because 13% of the population is estimated to have HIV.

I think the true mean population proportion from the 100 simulations would be close to 0.13, the HIV prevalence rate that was estimated in the actual study. This is because the simulations are randomly generated, and the probability of a simulated resident having HIV is 13%.

This is a simulation of an observational study. This is because the researchers are not intervening in the lives of the simulated residents. They are simply observing the HIV status of the simulated residents.

The margin of error for this study is 0.06, which is 6%. This means that the true population proportion of people with HIV could be anywhere between 0.07 and 0.19. The drug manufacturer's claim that 13% of the population has HIV is within this range, so we cannot definitively support or refute their claim.

To make the margin of error smaller and get a better sample of the population, we could increase the sample size. This would give us more data points to work with, which would make our estimate of the population proportion more accurate. Additionally, we could stratify the sample by age, gender, or other factors that could affect the prevalence of HIV. This would help us to ensure that our sample is representative of the entire population.
