16 ÷ 22 + (6 x 2) - 8
stepladder [879]
I did the PEMDAS method (P= parentheses, E= exponents, M= multiplication, D = Division, A= addition, S = subtraction.)

First I did what’s inside the parentheses, (6x2) and got 12.

Then I divided 16 by 22 and received 0.72.

I added 0.72 with 12 and the result was 12.72.

Last step was to subtract 12.72 - 8 and that equals 4.72

Harman [31]

Using addition of variables, it is found that the mean of S is of 73 and the standard deviation is of 8.5.

<h3>What happens to the mean and the standard deviation when two variables are added?</h3>
  • The mean is the sum of the means.
  • The standard deviation is the square root of the sum of variances.

In this problem, for variables A and B, we have that:

\mu_A = 35.5, \sigma_A = 5.1

\mu_B = 37.3, \sigma_B = 6.8

Variable S is the sum of A and B, hence:

\mu_S = \mu_A + \mu_B = 35.5 + 37.3 = 73

\sigma_S = \sqrt{\sigma_A^2 + \sigma_B^2} = \sqrt{5.1^2 + 6.8^2} = 8.5

The mean of S is of 73 and the standard deviation is of 8.5.

Plsssssssssssssss help​
gavmur [86]

Answer:

<em>(D). (8, - 5) </em>

Step-by-step explanation:

Coordinates of a center of a circle (x - h)² + (y - k)² = r² is (h, k)

Coordinates of the midpoint are ( \frac{x_{1} +x_{2} }{2} , \frac{y_{1} +y_{2} }{2} )

(x² - 10x + 25) + (y² + 2y + 1) = 25

(x - 5)² + (y + 1)² = 5²

(5, - 1) are coordinates of the center of the circle and (5, - 1) is a midpoint of the segment connected (2, 3) and (x, y)

5 = (2 + x) / 2 ⇒ x = 8

- 1 = (3 + y) / 2 ⇒ y = - 5

<em>(D). (8, - 5)</em>

olga nikolaevna [1]

Answer:

a) H0 = 15 m, is the initial height, the height of the rocket at time 0 s.

b) D=[0,5]

c) R=[0,35]    

Step-by-step explanation:

a) H0 is the initial height. It means the height of the rocket at time 0 s.

This value is 15 m.

b) The domain is all values of t between 0 and 5 seconds.

D=[0,5]

c) The range is all values of height from 0 to 35 meters.

R=[0,35]      

I hope it helps you!
