1 volunteer - 4 h - 48 calls
12 volunteers - 4 h - x calls
The time is the same, so it's irrelevant.
1 volunteer - 48 calls
12 volunteers - x calls
x=12*48=576
So it's 576 hours.
<span>let the width of the strip x in meters
we need to find the value of x
Dimensions of the new lawn are given as
</span>(7+x) by (5+x)
Area of the lawn is given as
6.25m^2
<span>
(7+x)(5+x) = 6.25
</span><span>35 + 12x + x^2 = 6.25
x^2 + 12x+28.75 = 0
In the above equation the values are given as
a = 1, b=12, c=28.75
</span>put these values in quadratic equation and you will get the answer.<span />
Answer:
A
Step-by-step explanation:
Find the common factors between the 2:
2πr + 4πrh
2 (πr+2πrh)
2πr (1 + 2h)
Answer:
105
Step-by-step explanation:
7*15=105 length times width
Answer:
X₀ = 71.65
Step-by-step explanation:
given,
mean (μ ) = 64
standard deviation (σ) = 9
σ² = 81
selected candidate are top 20 % candidate
P( X > X₀) = 0.2
P( Z > Z₀) = 0.2
X₀ = 71.65
Hence, the cut off score is equal to X₀ = 71.65
