Answer:
5
Step-by-step explanation:
f(-1)= -3(-1)³+2(-1)²
= -3(-1)+2(1)
= 3+2
=5
The answer is B) $18.00. (21.25)(.85) = $18.0625, and the closest is $18.00
I don't understand the problem what are you solving for?
Answer:
<h2>0.7</h2>
Step-by-step explanation:
The coefficient of determination which is also known as the R² value is expressed as shown;
Sum of square of total (SST)= sum of square of error (SSE )+ sum of square of regression (SSR)
Given SSE = 60 and SSR = 140
SST = 60 + 140
SST = 200
Since R² = SSR/SST
R² = 140/200
R² = 0.7
Hence, the coefficient of determination is 0.7. Note that the coefficient of determination always lies between 0 and 1.
Answer:
c = 12
Step-by-step explanation:
the ratio of sides in a 30-60-90° triangle, respectively, is 1: : 2
if side opposite 30° is 6 then hypotenuse equals 12
