Step-by-step explanation:
Formula = A=2(wl+hl+hw)
=> A=2(wl+hl+hw)
=> A = 2((2)(4)+(2.5)(4) + (2.5)(2))
=> A = 2(8 + 10 + 5)
=> A = 2(23)
=> A = 46
Surface area = 46
<u>Answer:</u>
The Ranking Percentile is (B) 97.5%
<u>Explanation
:</u>
To find the percentile rank we need to find the z- score. After finding the z-score match this value with the corresponding value in z-score table.
Formula to find the z-score
Z-score=
Substituting the values in the above equation, we find
Z-score= =2
So, the Z-score is +2
Now, the corresponding value of Z-score 2 in the table is 0.9772
or the percentile score is 97.72 ~ 97.5
.

Answer:
The diameter is: d = 5m
Step-by-step explanation:
We know that
Circumference of Circle = 2πr
Given that
The circumference of a circle = 5π
so the equation becomes
Circumference of Circle = 2πr
5π = 2πr
2πr = 5π
r = 5π/2π
r = 5/2 m
As we know that:
The diameter is twice the radius. i.e. d = 2r
Thus, the diameter is:
d = 2(5/2)
= 5 m
Therefore, the diameter is: d = 5m
Answer:
True -
Step-by-step explanation:
Given : The range of the function given below is the set of all positive real numbers greater than 5 ,
To find : The given statement is true or false?
Solution :
Domain of the function is where the function is defined
The given function is an exponential function
So, the domain of the function is,
i.e, The set of all real numbers.
Range is the set of value that corresponds to the domain.
Let
If
If
So, The range of the function is
Therefore, The given statement is true.
