Jada and lin are comparing inches and feet. Jada says that the constant of proportionality is 12. Lin says it is 1/12

Oksi-84 [34.3K]

Answer:

Jada compared ratio of feet to inches while Lin compared ratio of inches to feet.

Step-by-step explanation:

Let

Inches = x

Feet = y

Constant of proportionality = k

ratio of feet to inches

x = ky

1 feet = 12 inches

12 = k * 1

k = 12/1

k = 12

Ratio of inches to feet.

y = kx

1 = k * 12

k = 1/12

Jada compared ratio of feet to inches while Lin compared ratio of inches to feet.

The lengths of pregnancies are normally distributed with a mean of 268 days and a standard deviation of 15 days. If 64 women are

shtirl [24]

Answer:

0.3569 is the probability that they have a mean pregnancy between 266 days and 268 days.

Step-by-step explanation:

We are given the following information in the question:

Mean, μ = 268 days

Standard Deviation, σ = 15 days

We are given that the distribution of lengths of pregnancies is a bell shaped distribution that is a normal distribution.

Formula:

$z_{score} = \displaystyle\frac{x-\mu}{\sigma}$

Standard error due to sampling =

$\displaystyle\frac{\sigma}{\sqrt{n}} = \frac{15}{\sqrt{64}} = \frac{15}{8}$

P(pregnancy between 266 days and 268 days)

$P(266 \leq x \leq 268) = P(\displaystyle\frac{266 - 268}{\frac{15}{8}} \leq z \leq \displaystyle\frac{268-268}{\frac{15}{8}}) = P(-1.0667 \leq z \leq 0)\\\\= P(z \leq 0) - P(z < -1.067)\\= 0.5000 - 0.1431 = 0.3569 = 35.69\%$

$P(266 \leq x \leq 268) = 35.69\%$
