Answer:
c
Step-by-step explanation:
a. 3in, 4in, 5 in
5^2 ? 3^2 + 4^
25 ? 9 + 16
25 = 25
Because the two sides are equal, this is a right triangle.
b. 5in, 6in, 7in
7^2 ? 5^2 + 6^2
49 ? 25 + 36
49 < 61
Because 49 < 61, this is an acute triangle.
c. 8in, 9in, 12in
12^2 ? 8^2 + 9^2
144 ? 64 + 81
144 < 145
Because 144< 145, this is an acute triangle.
A complement adds up to 90 degrees, so we just need to halve that, to get 45 degrees.
<span>When doing linear regression, if the correlation coefficient is Negative, the slope of the line is Negative .
</span><span>When doing linear regression, if the correlation coefficient is positive, the slope of the line is positive.
So according to above explanation it is TRUE</span>
