Answer:
True. 3:4 is the same as 30:40 because they both times 10
Step-by-step explanation:
B/10 = 3/5
B x 5 = 5b
10 x 3 = 30
5b = 30
Divide 5b and 30 to 5
B=6
Here the solution in in picture.
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)
