Answer 1

Answer:

B

Step-by-step explanation:

A=3.14*6^2

6*6=36

36*3.14= 113

144-113= 31 (aka 30.96)

side note- 144 is the area of the square

Answer 2

Answer:

[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]

[tex]Area\ of\ the\ given\ circle=113.04\ mm^2\\Now,\\As\ the\ Area\ of\ the\ Square - Area\ of\ the\ Circle\ is\ the\ Shaded\ Region,\\144-113.04= Area\ of\ the\ Shaded\ Region\\Hence,\\Area\ of\ the\ Shaded\ Region=30.96\ mm^2[/tex]

Complete question :

Online photos: A poll surveyed 1765 internet users and found that 865 of them had posted a photo or video online. Can you conclude that less than half of internet users have posted photos or videos online? Use the α 0.01 level of significance and the P-value method with the TI-84 calculator.

1. State the appropriate null and alternate hypotheses.

2. Compute the P-value.

Answer:

H0 : p = 0.5

H1 : p < 0.5

P value = 0.200454

Step-by-step explanation:

Given that :

Claim : Less than half internet users have posted photos or videos online.

Sample Proportion (p) = 865 / 1765 = 0.4900

The null hypothesis : H0 : p = 0.5 (that is half of internet users have posted photos online.

The alternative hypothesis : H1 : p < 0.5 (that is less than half of internet users have posted photo or video ;

P = 0.5

q = 1 - 0.5 = 0.5

The test statistic :

Z = p - p0 / sqrt(p0 * (q/n))

Z = (0.49 - 0.5) / sqrt(0.5 * (0.5/1765))

Z = - 0.01 / sqrt(0.5 *0.0002832)

Z = - 0.01 / sqrt(0.0001416)

Z = - 0.01 / 0.0119013

Z = - 0.8402443

The corresponding p value from the z statistic score at α = 0.01

= 0.200454

your 3 math answer scores are 75,98 and 91 what is your average score​

Answers

Answer:

88

Step-by-step explanation:

It is given that,

Three scores are 75,98 and 91.

We need to find average score.

The formula to find the average is given by :

[tex]\text{Average}=\dfrac{\text{sum of observations}}{\text{total no of observations}}[/tex]

Using the above formula,

[tex]A=\dfrac{75+98+91}{3}\\\\=88[/tex]

Hence, my average score is 88.

Rewrite the expression as a product using the GCF and distributive property. 27 + 45

Answers

Step-by-step explanation:

GCF of 27 and 45 is 9

Answer: 9 (3+5)

Step-by-step explanation:

The GFCF of these two numbers is 9 as they can both be divided by it

Distributive property form is when you place the GFC outside parenthesis so that the equation can be multiplied in order to show the original equation and dividing the numbers by the GCF so that it does not give you a larger number than what you started with

27/9=3 + 45/9=5

So, keeping this in mind the distributive property form would be 9(3+5)

Answers

Answer:

its B on e2020

Step-by-step explanation:

14%

If the Algerian government wishes to raise $9 billion in tax revenue, income tax rate should be 14%.

What should the income tax rate be?

Income tax is a form of tax levied on the income of labor by the government. Income tax reduces the income earned by labor.

In order to determine the income tax rate, take the following steps:

Determine the total income of the workforce: 9,416,534 x $6,844 = 64.45 billion

Now, divide the desired tax revenue by the total income: (9 billion / 64.45 billion)  x 100 = 14%

Answers

Answer:

3.188

Step-by-step explanation:

Given that :

Sample data: 26.5, 28, 30.2, 29.6, 32.3, 24.7

Sample standard deviation (s) = 2.728

Mean (mu) = 25

Tstatistic formula :

(x - mu) / (s/sqrt(n))

n = sample size = 6 ; s = 2.728 ; mu = 25

Sample mean (x) = (26.5 + 28 + 30.2 + 29.6 + 32.3 + 24.7) / 6

Sample mean (x) = 171.3 / 6 = 28.55

Tstatistic = (28.55 - 25) / (2.728 / sqrt(6))

Tstatistic = 3.55 / 1.1137013

Tstatistic = 3.1875692
