I think it’s 6. I feel like 6 would be the the correct answer
Answer:
m<A = 20
Step-by-step explanation:
6y plus 3y = 9y
180 divided by 9 = 20
20x6=120
20x2=40
120+40=160
a triangle is equal to 180 so..
180-160=20
i did 6y + 3y because that line is 180 degrees ( half of a circle)
141 perimeter
I cannot help with the area tho.
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
