Answer:
The sports shop has 21 part-time employees.
Step-by-step explanation:
Solution:
What is 25% of 84?
.Y is 25% of 84
Equation: Y = P% * X
Solving our equation for Y
Y = P% * X
Y = 25% * 84
Converting percent to decimal:
p = 25%/100 = 0.25
Y = 0.25 * 84
Y = 21
Or another quicker way....
50% is half of the whole, and 25 is half of 50.
84/2/2
equals 21 too, I don't recommend to use it as row form.
Answer:
A
Step-by-step explanation:
Carlos' score was 2 standard deviations from the mean, so his z-score was 2.0. You can either use the empirical 68-95-98.5 rule, or you can plug it into your calculator as <u>normalcdf(-999, 2) = .977</u>
So 97.7% of people had a score lower than Carlos!
.977 * 1.5 million = 1,465,500 people
V = PI x r^2 x H
471 = 3.14 x 5 x H
471 = 15.7 x h
h = 471 / 15.7 = 30 cm
314/ 15.7 = 20 cm
30-20 = 10 cm difference
This is not much of a question, because it doesn't take into account the width of the wood trim.
So you are asked to find the perimeter of the window, ignoring the width of the trim.
P = Perimeter = 2L + 2W.
Here, P= 2(9 1/3 feet) + 2(6 3/4 feet) = 2(28/3 feet) + 2(27/4 feet)
So P = 2[28/3 + 27/4] feet. LCD is 3*4 = 12.
Thus, P = 2 [ 28/3 + 27/4 ] feet. Can you finish? Add together the fractions 28/3 and 27/4.
