1 answer:
Alisiya [41]2 years ago
3 0

Answer:  27x²yz + 3xz² - 2xy - 2y²z + 2yz²  

<u>Step-by-step explanation:</u>

Use the distributive property.

   3xz(9xy + z)           - 2yz(x + y - z)

= 3xz(9xy)  +  3xz(z)  -2yz(x)   -2yz(y)   -2yz(-z)

=  27x²yz   +   3xz²    -2xy       -2y²z      +2yz²

Tpy6a [65]

Answer:

B. Yuri divided by n instead of n-1

Step-by-step explanation:

It was stated in the question that the dataset was sample dataset. For a sample dataset, the standard deviation is given by the formula,

σ = √ Σ (Xi - mean)²/(n - 1) where i = 1,2,3.....n

Since this is just a sample dataset and not the whole population, Yuri should have divided by n-1 instead of n.

What is
ehidna [41]
To find slope subtract the two points in the coordinate (y). We have 8 and 4 so subtract those two. You get 8-4=4. Now start from the same coordinate expect this time subtract (x). Which is 9-3=6. You have 4/6 simplify and you get 2/3. Your slope is 2/3. Hope this helps

What is the density of an object having a mass of 25 g and a volume of 8.0 cm cubed
weqwewe [10]

Answer:

3.125 g/cm³.

Step-by-step explanation:

The formula for density/mass/volume is d = m/v, where d is density in grams per cm cubed, m is in grams, and v is in cm cubed.

In this case, m = 25 and v = 8.0.

d = 25 / 8.0

d = 25 / 8

d = 3.125.

So, the density of the object is 3.125 g/cm cubed.

Hope this helps!
