Plug in the values:

((211,500 - 700) / 700) x 100

,Line segment PQ is shown on a coordinate grid:
Marina86 [1]

Answer:

P'Q' is equal in length to PQ.

Step-by-step explanation:

Before rotation

P(-5, 3)

Q(-1, 3)

we get the length

L = √((-1-(-5))²+(3-3)²) = √((-4)²+(0)²) = 4

After rotation

P'(3, 5)

Q'(3, 1)

we get the length

L' = √((3-3)²+(1-5)²) = √((0)²+(-4)²) = 4

we can say that   L = L' = 4

P'Q' is equal in length to PQ.

natali 33 [55]

Answer: 0.4207

Step-by-step explanation:

Let \overline{x} be the sample mean area.

Given: Population mean : \mu=250 sq. feet

Standard deviation: \sigma=2 sq. feet

Sample size : n= 10

The probability that the sample mean area is 249.6 \text{ ft}^2 or less if the manufacturer’s claim is true.

P(\overline{x}

Required probability = 0.4207
