5x^2 - 5 = -17
First add 5 to both sides:
5x^2 = -12
Now, divide by 5
x^2 = -12/5
Take the square root of both sides
x = sqrt -12/5
Because there can't be a square root of a negative number, your answer is:
x = sqrt -12/5 * i
Hope this helps!
Answer:
width (C.I) ∠ width (P.I)
Step-by-step explanation:
In statistics, a confidence interval (C.I) is known as an interval estimate which is computed using the observed data that might contain the actual value of an unknown parameter. The confidence level is commonly used for estimation before examining the actual data. On the other hand, the prediction interval (P.I) is a range of values that calculate the value of a new observation by considering the existing model developed using the actual data. Therefore, the true statement is:
width (C.I) ∠ width (P.I)
Answer:
-12
Step-by-step explanation:
So you would change 4 4/5 to 4 8/10 and then do 4-2=2 and 8/10 - 1/10= 7/10 so the work is 2 7/10
One way is to trace around one of the triangles and place it over the other. If<span> the angles and sides match exactly, then the </span>two<span> are </span>congruent<span>.
