To find the sum of an infinite geometric series having ratios with an absolute value less than one, use the formula, S=a11−r, where a1 is the first term and r is the common ratio.
Answer:
8.6
Step-by-step explanation:
This uses the Pythagorean Theorem
a^2 + b^2 = c^2
a = 5
b = 7
c = ?
5^2 + 7^2 = c^2
25 + 49 = c^2
74 = c^2
sqrt(c^2) = sqrt(74)
c = 8.60 which when rounded = 8.6
(1, 2)
plug 1 in for x and 2 in for y
2x1=2 is 2=2
Answer:
The co variance of the midterm and final exam scores is 58.76.
Step-by-step explanation:
The formula to compute the sample co variance is:

The values are computed in the table below.
Compute the co variance as follows:

Thus, the co variance of the midterm and final exam scores is 58.76.
Answer:
<h3>
m∠1 = 72°</h3>
Step-by-step explanation:
We know: The sum of the measures of a triangle is 180°.
Therefore we have the equation:

We have

Substitute:

<em>subtract 108° from both sides</em>
