21 feet to 8 yards write a ratio as a fraction in simplest form without any units

Dmitriy789 [7]

We know, 3 feet = 1 yard.

We have to convert feet to yards to calculate the ratio so that the final answer doesn't have any unit.

Therefore, 21 feet = $\frac{21 feet}{3 feet}yards$ = 7 yards

Thus, the ratio

$\frac{21feet}{8yards} =\frac{7yards}{8yards} =\frac{7}{8}$

The fraction $\frac{7}{8}$ is already in its simplest form.

Therefore, the given ratio as a fraction in the simplest form without any units is $\frac{7}{8}$

A college-entrance exam is designed so that scores are normally distributed with a mean of 500 and a standard deviation of 100.

Crank

Answer: 1.25

Step-by-step explanation:

Given: A college-entrance exam is designed so that scores are normally distributed with a mean $(\mu)$ = 500 and a standard deviation $(\sigma)$ = 100.

A z-score measures how many standard deviations a given measurement deviates from the mean.

Let Y be a random variable that denotes the scores in the exam.

Formula for z-score = $\dfrac{Y-\mu}{\sigma}$

Z-score = $\dfrac{625-500}{100}$

⇒ Z-score = $\dfrac{125}{100}$

⇒Z-score =1.25

Therefore , the required z-score = 1.25
