Answer:

By the Empirical Rule, in 99.7% of the games that Aubree bowls she scores between 148 and 232Step-by-step explanation:The Empirical Rule states that, for a normally distributed random variable:68% of the measures are within 1 standard deviation of the mean.95% of the measures are within 2 standard deviation of the mean.99.7% of the measures are within 3 standard deviations of the mean.In this problem, we have that:Mean = 190Standard deviation = 14Using the empirical rule, what percentage of the games that Aubree bowls does she score between 148 and 232?148 = 190 - 3*14So 148 is 3 standard deviations below the mean.232 = 190 + 3*14So 232 is 3 standard deviations above the meanBy the Empirical Rule, in 99.7% of the games that Aubree bowls she scores between 148 and 232

Create an inequality for the situation below.<br><br> Please help!!
OlgaM077 [116]

1 gallon of milk costs 0.50 more than 5 times a gallon of water.

From that information milk is 5x +0.50 the cost of water.


The cost of milk is $3.75, so now we have:

3.75 = 5x + 0.50


Subtract 0.50 from each side:

3.25 = 5x

Divide both sides by 5:

X = 3.25 / 5

x = 0.65

The cost of water = $0.65

Answer:

The volume of rectangular prism is \frac{24}{105} inches³

Step-by-step explanation:

Given as :

The Length of rectangular prism = L = \frac{2}{3} inches

The Breadth of rectangular prism = B = \frac{3}{5} inches

The Height of rectangular prism = H = \frac{4}{7} inches

Let The volume of rectangular prism = V inches³

A rectangular prism is a 3-D figure with 6 faces

Now, <u>From formula of rectangular prism</u>

Volume = Length × width × height

Or, V = L × B × H

Or, V =  \frac{2}{3} inches ×  \frac{3}{5} inches × \frac{4}{7} inches

or, V = \frac{2\times 3\times 4}{3\times 5\times 7} inches³

or, V = \frac{24}{105} inches³

So,  The volume of rectangular prism = V  =  \frac{24}{105} inches³

Hence The volume of rectangular prism is \frac{24}{105} inches³ Answer
