A computer company produces an extremely light laptop and they claim it is the lightest on the market weighing only 32 ounces. t

Darina [25.2K]

Solution: We are given:

$\mu=0.33, \sigma =0.7$

Let $x$ be the weight (oz) of laptop

We have to find $P(x>32)$

To find the this probability, we need to find the z score value.

The z score is given below:

$z=\frac{x-\mu}{\sigma}$

$=\frac{32-33}{0.7}$

$=-1.43$

Now, we have to find $P(z>-1.43)$

Using the standard normal table, we have:

$P(z>-1.43)=0.9236$

0.9236 or 92.36% of laptops are overweight

During the course of a 2,185 mile trip, the Archetti's used 5 full tanks of gasoline. The gas tank of their car holds 23 gallons

Pepsi [2]

Okay, let's use some math..

So multiply first..

2.99 * 5 = $14.95 that she has spent on gas..

23 / 5 = 4.6 gallons of gas left..

But this question is asking how much she had spent on gas, so your answer will be..
She has spent $14.95 on gas..

You can correct me if I'm wrong..

I hope this helps you!

Evaluate: 5–^2 = <br> WILL MARK AS BRAINLIEST

Elanso [62]

When you have a negative exponent, you move it to the other side of the fraction to make the exponent positive.

For example:

$x^{-2}$ or $\frac{x^{-2}}{1}=\frac{1}{x^2}$
