Answer:

A. because if you take 265,000 and multiply by 5,880,000,000,000 you will get 1,558,200,000,000,000,000 and put into scientific notation is 1.5582 X 10E18 (which means to the power of 18) which makes the answer A. also I know I'm late I was stumped myself and decided to actually apply myself and look at me now

Use the difference of two squares to find the product of 22 and 18.

vladimir2022 [97]

Answer:

396

Step-by-step explanation:

Difference of two squares is breaking down numbers into pieces and using the distributive property to solve. The pieces should be in the form (a-b)(c+d).

Write 22 as (20 + 2) and 18 as (20-2).

(20+2)(20-2) = 400 + 40 - 40 - 4 = 400 - 4 = 396

In an area of the Midwest, records were kept on the relationship between the rainfall (in inches) and the yield of wheat (bushel

dusya [7]

Answer:

The correct answer is 36.2

Step-by-step explanation:

Hello!

Given the data:

Rainfall(inch) x: 10.5, 8.8, 13.4, 12.5, 18.8, 10.3, 7.0, 15.6, 16.0

Yield (bushels per acre) y: 50.5, 46.2, 58.8, 59.0, 82.4, 49.2, 31.9, 76.0, 78.8

The response variable is

Y: Yield of wheat (bushels per acre)

Explanatory variable:

X: Rainfall in a certain period (inch)

I've calculated the equation of regression using a statistics software, the estimated equation is:

^Y= 4.27 + 4.38X

To calculate the value that will take the response variable for a given value of X:

^Y= 4.27 + 4.38*7.3= 36.24 bushels per acre.

I hope it helps!

Why can't a triangle have more than one obtuse angle

vlada-n [284]

An "obtuse" angle is an angle that's bigger than 90 degrees.
So two obtuse angles would add up to more than 180 degrees.

But the three angles inside a triangle always add up to exactly 180 degrees.
So two of them can't be obtuse.
