To calculate averages you must first add all the test scores.

add 82, 90, 78, 76 and 94.

next choose one of the options and add it on to the sum that you got from the original test scores

now divide the whole thing by how many trials there were (how many tests were done). in this case, including the option, 6 trials were completed so divide by 6.

if the answer is not 86, then repeat for other options until you get 86

The sum of two polynomials is –yz2 - 322 – 4y + 4. If one of the polynomials is y - 4yz2 - 3, what is the other polynomial? 0 -2

JulsSmile [24]

Answer:

3yz² - 3z² - 5y + 7

Step-by-step explanation:

Sum of two polynomials = –yz² - 3z² – 4y + 4

One of the polynomial = y - 4yz²- 3

Find the other polynomial

The other polynomial = sum of the polynomials - one of the polynomial

= –yz² - 3z² – 4y + 4 - (y - 4yz² - 3)

= –yz² - 3z² – 4y + 4 - y + 4yz² + 3

= -yz² + 4yz² - 3z² - 4y - y + 4 + 3

= 3yz² - 3z² - 5y + 7

A. 0 -2yz?

B. – 4y + 7 01 - 2yz

C. – 3y + 1 0 -5yz² + 3z² – 3y + 1 D. 3yz² - 3z² – 5y + 7

The Pacific Crest Trail is a hiking trail that extends from Mexico to Canada and is about 2650 miles long. Suppose Xin hikes one

seraphim [82]

Answer:

Xin has hiked 2.65 miles of the trial.

Step-by-step explanation:

Given:

Distance of the trial hike = 2650 miles

portion of the trial Xin hikes = $\frac{1}{1000}$ of the trial.

We need find the distance she hiked.

Solution:

Now we can say that;

distance Xin hiked is equal to Distance of the trial hike multiplied by portion of the trial Xin hikes.

framing in equation form we get;

Distance Xin hike = $\frac{1}{1000}\times 2650 = 2.65 \ miles$

Hence Xin has hiked 2.65 miles of the trial.
