How do u solve (2d-5)/2 = (5d+2)/9
Rzqust [24]

Answer:

D=  49/8

Step-by-step explanation:

Cross-multiply.

(2d-5)/2 = (5d+2)/9

(2d−5)*(9)=(5d+2)*(2)

18d−45=10d+4

Subtract 10d from both sides.

18d−45−10d=10d+4−10d

8d−45=4

Add 45 to both sides.

8d−45+45=4+45

8d=49

Divide both sides by 8.

d=  49/8

So the answer is 49/8

I hope it's right!

Assume that females have pulse rates that are normally distributed with a mean of
juin [17]

Step-by-step explanation:

a. First, find the z-score.

z = (x − μ) / σ

z = (80 − 74.0) / 12.5

z = 0.48

Use a calculator or table to find the probability.

P(z < 0.48) = 0.6844

b. Find the standard deviation of the sample.

σₓ = σ / √n

σₓ = 12.5 / √4

σₓ = 6.25

Find the z-score.

z = (x − μ) / σ

z = (80 − 74.0) / 6.25

z = 0.96

Use a calculator or table to find the probability.

P(z < 0.96) = 0.8315

c. When the distribution of the population is normal, then the distribution of the sample mean is also normal.
