Whats the product (-2x-9y^2)(-4x-3)

1 answer:

8 0

Hello there!

(-4x-3)(-2x-9 $y^{2}$ )
-4x(-2x-9 $y^{2}$ ) = 8 $x^{2}$ +36 $xy^{2}$
-3(-2x-9 $y^{2}$ ) = 6x + 27 $y^{2}$

36xy^2 + 8x^2 + 27y^2 + 6x is your product polynomial.

I hope this helps!

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

Find the mean and range. 26 19 23 39 31 34 23 25

sveticcg [70]

Range: largest number minus the smallest number
39 - 19 = 20
your range is 20

Mean: add all of the numbers and divide by the amount of numbers there are.

26+19+23+39+31+34+23+25= 220
220/8 = 27.5

your mean is 27.5
