Answer:
24cm
Step-by-step explanation:
you do length times width and you get 24

Answer:
30
Step-by-step explanation:
The altitude is the geometric mean of the two segments of the hypotenuse. For some scale factor x, the segments are 1x and 4x, and the altitude is ...
12 = √((1x)(4x)) = 2x
6 = x
So, the length of the hypotenuse is ...
(1x) +(4x) = 5x = 5·6 = 30
The hypotenuse is 30 units long.
If you randomly purchase one item, the probability it will last longer than 9 years is; 11.12%
<h3>How to find the probability from z-score?</h3>
The formula for Z-score is;
z = (x' - µ)/σ
where;
x' = sample mean
µ = population mean
σ = standard deviation
Thus;
z = (9 - 7.9)/0.9
z = 1.22
From online p-value from z-score calculator, we have;
probability = 0.1112 = 11.12%

A because a function can NOT start with a 0 hope it helps:)
