Answer:

The mean is 9

Step-by-step explanation:

To find the mean, all you do is add up all the numbers and then divide by how many numbers there are. In this case, adding all then numbers up gives you 63, and there are a total of 7 numbers. 63 divided by 7 =9

Using the variance concept, it is found that the correct option is:

B. must be at least zero

Since the variance is squared, it's minimum value is 0, and thus, the correct option is:

B. must be at least zero

Answer:

z = 4/3 or 1 1/3

Step-by-step explanation:

z−4/9−1/3=5/9

Change 1/3 to have a denominator of 9

1/3 *3/3 = 3/9

z−4/9−3/9=5/9

Combine like terms

z -7/9 = 5/9

Add 7/9 to each side

z-7/9+7/9 = 5/9+7/9

z = 12/9

z=4/3

or as a mixed number

z = 1 1/3

x=53

Step-by-step explanation:

all triangles equal 180° the little lines on each side mean both sides are same length so all u gotta do is

180-74=106

106/2= 53

Answer:x=52

180-74=104

104 divided by 2 to get 52

Step-by-step explanation: you would have to divide because both sides are the same size so they would be even. so that is how you would get the answer 52

Answer:

n great than 13.

hope this isn't wrong

The solution to the inequality is n > 13. This means that any value of n greater than 13 will satisfy the inequality.

Given is an inequality n - 8 > 5, we need to solve it,

To solve the inequality "n - 8 > 5," you can follow these steps:

Step 1: Add 8 to both sides of the inequality to isolate the variable n.

(n - 8) + 8 > 5 + 8

n - 8 + 8 > 13

n > 13

Step 2: Simplify the inequality.

n > 13

Hence the simplified inequality is n > 13.

Step-by-step explanation:

The volume of cylinder = [tex]\pi r^{2}h[/tex]

The radius of cylinder = 20 ÷ 2 = 10

The volume of cylinder = [tex](\frac{22}{7})(10^{2} )(7)[/tex]

= [tex](22)(100)[/tex] = 2200

please give me a brainliest answer

Answer:

Solution:

volume of a cylinder = area of base(pi × radius²) × altitude (height)

Volume = πr² × altitude

V = 3.14 × 10² × 7

V = 3.14 × 100 × 7

V = 314 × 7

V = 2,198 cm

Answer:

18°

Step-by-step explanation:

1. ∠A and ∠B are complementary angles, so they add up to 90°.

2. To find the measure of ∠A, we first have to solve for x.

3. (Solving)

Step 1: Simplify both sides of the equation.

Step 2: Subtract 13 from both sides.

Step 3: Divide both sides by 7.

4. Now that we know x = 11, let's plug that value into (2x - 4) to find the measure of Angle A.

Therefore, the measure of ∠A = 18°.

Answer:

m<A = 18

Step-by-step explanation:

Since <A and <B are complementary angles, that just means those 2 angles combined equal 90:

<A + <B = 90

2x - 4 + 5x + 17 = 90

7x + 13 = 90

7x = 90 - 13

7x = 77

x = 77/7

x = 11

m<A:

2x - 4

2(11) - 4

Answer:

f(g(2)) = 30

Step-by-step explanation:

Evaluate g(2) , then substitute the value obtained into f(x)

g(2) = 2(2) + 11 = 4 + 11 = 15 , then

f(15) = 3(15) - 15 = 45 - 15 = 30

Step-by-step explanation:

[tex]f(x) = 3x - 15 \\ g(x) = 2x + 11 \\ f(g(x)) = 3(2x + 11) - 15 \\ f(g(x)) = 6x + 33 - 15 \\ f(g(x)) = 6x + 18 \\ f(g(2)) = 6(2) + 18 \\ f(g(2)) = 12 + 18 \\ \boxed{f(g(2)) = 30}[/tex]
