At a certain bakery, the price of each doughnut is $1.50. Let the random variable D represent the number of doughnuts a typical
Solnce55 [7]

Using <em>statistical concepts</em>, it is found that the standard deviation of the probability distribution is of

s = 1.5(1.9) = 2.85

When a constant is multiplied to each data in a variable, both the <u>mean and the standard deviation</u> are multiplied by the constant.

In this problem, the standard deviation, which is the square root of the variance, is of:

\sigma = \sqrt{\sigma^2} = \sqrt{3.6} = 1.9

The price of each is of $1.5, hence:

s = 1.5(1.9) = 2.85

Please please help me with this please
ziro4ka [17]

Answer:

y + 20 = 9(x + 2)

Step-by-step explanation:

The equation of a line in point- slope form is

y - b = m(x - a)

where m is the slope and (a, b) a point on the lie

Calculate m using the slope formula

m = (y₂ - y₁ ) / (x₂ - x₁ )

with (x₁, y₁ ) = (- 2, - 20) and (x₂, y₂ ) = (9, 79)

m = \frac{79+20}{9+2} = \frac{99}{11} = 9

Using (a, b) = (- 2, - 20), then

y - (- 20) = 9(x - (- 2)), that is

y + 20 = 9(x + 2)

1/3 of students at a school are boys. If there are 600 students, how many of them are girls?
Nadya [2.5K]

400

Explanation:

1/3 of 600 is 200. That represents the boys.

Subtract 200 from 600, you get 400. That represents everybody else in the sample size (in this case, girls).
