Ms. Klein wants to put a fence around her garden. The garden is in the shape of a semi-circle with a radius of 12 feet. How much

sukhopar [10]

Answer:

P = 61.70 feets

Step-by-step explanation:

Based on the information given :

For fencing , We need to calculate the perimeter of the semicircle ;

Perimeter of a semicircle is given as :

P = πr + 2r

P = perimeter ; r = Radius = 12 feets

P = 12π + 2*12

P = 12π + 24

P = 61.699111 feets

P = 61.70 feets

To. Obtain how much.

We multiply the perimeter by the cost per feet.

HURRY I NEED HELP: Write an equation in point-slope form of the line that passes through the point (3, 5) and has a slope of m=−

skelet666 [1.2K]

Answer:

$\huge y - 5 = - 1(x - 3) \\$

Step-by-step explanation:

To find an equation of a line in point slope form when given the slope and a point we use the formula

$y - y_1 = m(x - x_1)$

From the question we have the final answer as

$y - 5 = - 1(x - 3)$

Suppose a normal distribution has a mean of 62 and a standard deviation of

Alekssandra [29.7K]

The probability that a data value is between 54 and 66 is 81.9%

z score is used to determine by how many standard deviations the raw score is above or below the mean.

The z score is given by:

$z = \frac{x-\mu}{\sigma} \\\\where\ x=raw\ score,\mu=mean,\sigma=standard\ deviation$

Given that μ = 62, σ = 4

For x = 54:

$z=\frac{54-62}{4}=-2$

For x = 66:

$z=\frac{66-62}{4}=1$

P(54 < x < 66) = P(-2 < z < 1) = P(z < 1) - P(z < -2) = 0.8413 - 0.0228 = 81.9%

The probability that a data value is between 54 and 66 is 81.9%
