Answer:
xˆ2+10x+9
Step-by-step explanation:
first, multiply x by x and by 1, that would be (xˆ2 and x), then multiply 9 by x and 1, that would be( 9x and 9), add the two parenthesis, and it totals out to xˆ2+10x+9
You mean conversion factor? The answer would be 8. There are 4 quarts in a gallon and 2 pints to each court for a total of 8 pints
Answer:
Step-by-step explanation:
So 5.40 divided by 12
The perimeter would be the sum of the side lengths of the figure. Therefore, from the figure the perimeter would be the sum of the rectangle and half of the circle. We calculate as follows:
Perimeter = 2(pi)r / 2 + (2w + 2l)
Perimeter = pi(6/2) + 2(3) + 2(6)
Perimeter = 27.4 mm
Answer:
The critical values of r are -0.708 and 0.708.
Step-by-step explanation:
A statistical test is being performed to determine whether there is any linear correlation between two variables.
The hypothesis can be defined as follows:
<em>H</em>₀: There is no linear correlation between two variables, i.e. <em>ρ</em> = 0.
<em>H</em>ₐ: There is a significant linear correlation between two variables, i.e. <em>ρ</em> ≠ 0.
The test statistic is given as follows:

The degrees of freedom of the test is:

The significance level of the test is, <em>α</em> = 0.01.
The critical values of <em>r</em> are:

*Use the <em>r</em> critical value table.
Thus, the critical values of r are -0.708 and 0.708.
