By how much is the product of 9/5 and 8 1/4 greater than 5

Oliga [24]

Given:

The product of $\dfrac{9}{5}$ and $8\dfrac{1}{4}$ greater than 5.

To find:

By how much the product of $\dfrac{9}{5}$ and $8\dfrac{1}{4}$ greater than 5.

Solution:

First we need to find the product of $\dfrac{9}{5}$ and $8\dfrac{1}{4}$ .

$\text{Product}=\dfrac{9}{5}\times 8\dfrac{1}{4}$

$\text{Product}=\dfrac{9}{5}\times \dfrac{8(4)+1}{4}$

$\text{Product}=\dfrac{9}{5}\times \dfrac{33}{4}$

$\text{Product}=14.85$

Now subtract 5 from the product.

$14.85-5=9.85$

Therefore, the product of $\dfrac{9}{5}$ and $8\dfrac{1}{4}$ is 9.85 greater than 5.

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

Given:

A rectangular piece of cloth (dimensions):

L = length of the rectangle
W = width of the rectangle

The area of the rectangle is:

A = L x W

If the cloth is cut along the diagonal, the area of one sail will be half the area of the rectangle:

A (one sail) = 1/2 (L x W) <span />
