Answer:7pi\4
Step-by-step explanation:
68
Explanation:
So to get this answer you need to split it into smaller shapes. We already have the squares so we know that 3*3 is 9 and then we double that because there are two of them.
So, so far we have 18+x
We need to take the middle shape and split it into two trapezoids.
The area for trapezoids is T=(a+b/2)h
So T= (3+7/2)5
T= 5*5=25
And then we would double that because there are two of them so 50 and then fill it in for x
18+50= 68 is the area of the figure.
Answer:
slope: -1/2
y-intercept: -2
Step-by-step explanation:
f(x) = mx+b
m is slope
b is the y-intercept
so
if f(x) = -1/2x - 2
then
the slope or m is -1/2
and the y-intercept or b is -2
10 - 2(7)
10 - 14 = -4
A is the answer
Answer:
C) 3.03
Step-by-step explanation:
<u><em>Step(i):-</em></u>
Given sample size 'n' = 50
The Mean of the population (μ) = 62
The standard deviation of the Population (σ) = 7
Mean of the sample(x⁻) = 65
Z-score

<u><em> Step(ii):-</em></u>
<em> </em>
<em></em>
<em> Z = 3.03</em>
<u><em>Final answer:-</em></u>
<u><em>The Z-score = 3.03</em></u>
