3×3×3×3 (divide)
= 16/81
hope it helpsss!!
can you mark me as the brainliest
The answer to your question is
h=2y+36
why?
because he was already 36 inches which mean he would be adding on the inches.
So he would grow 2 inches a year plus the 36 inches he already was.
Hope this helps
Answer:
b. Pearson's correlation can be used in the same way as it is for linear relationships
Explanation:
Pearson's correlation can also be termed "simple linear regression analysis" is a statistical measure used to determine if two numeric variables are significantly linearly related. Pearson's correlation coefficient is used to measures the statistical relationship or association between two continuous variables.
First off, the underline underneath means plus or minus, since when you take the square root of something, the answer can be negative or positive at the same time
1. 64 is a perfect square. 8 x 8 = 64, therefore it is +- (plus or minus) 8.
2. 45 is not a perfect square, so you can pull out numbers or plug into a calculator and estimate.
Both answers: Since 45 is divisible by 9 and five, you can break a nine into two threes, therefore pull it out, and since the answer is negative, you get:
-3(5)^0.5 (an exponent of one-half or 0.5 means square root)
If you solve by calculator, the answer is ~= (approximately equal to) -6.72
3. Since 90 is not a perfect square, repeat the previous question. 9 can go into 90, therefore you can pull out two threes and are left with: +-3(10)^0.5
Using the calculator, you get ~= +-9.49
For this case we have that by definition, a linear equation is of the form:
The variable (s) involved in the equation always have exponent 1.
Some examples of linear equations are:
Answer:
In a linear equation the variables have exponent 1.
