The answer is 6:
6+18= 24
24 divided by 4= 6
b=6
The value of the z test statistic will be 2.55.
<h3>What is the z test statistic?</h3>
The z test statistic is a statistical evaluation of a value's correlation to the mean of a collection of values, expressed in terms of standard deviation.
The z test statistics is given as
z = (x – μ) / σ
Where μ is the mean, σ is the standard deviation, and x is the sample.
A sample of 25 provided a sample mean μ = 14 and a sample standard deviation σ = 4.32.
Then the value of the z test statistic will be
z = (x – μ) / σ
z = (25 - 14) / 4.32
z = 11 / 4.32
z = 2.546 ≈ 2.55

Correct answer is D
Would appreciate brainliest answer :)
Ratio being 3:5:7
longest being 56 so
7x=56
x=8
multiply the other lengths by 8
3*8=24
5*8=40
making the final
24:40:56
The altitude of an equilateral triangle with side length 
is 
.
So, the length of the altitude is
