A Z-score helps us to understand how far is the data from the mean. The correct option is D. The weight will be 54.6 grams.
What is Z-score?A Z-score helps us to understand how far is the data from the mean. It is a measure of how many times the data is above or below the mean. It is given by the formula,
Z = ( X - μ ) / σ
Where Z is the Z-score,
X is the data point,
μ is the mean and σ is the standard variable.
The weight of a randomly selected pack of gum has a z-score of 3.11. Therefore, The weight of this pack of gum is heavier than the mean weight by 3.11 standard deviations.
Z = ( X - μ ) / σ
3.11 X 2.4 = X - 47.1
X = 54.6 grams
Hence, the correct option is B.

Answer:
You will need 800 [tex]ft^{3}[/tex] of water to fill the pool.
Step-by-step explanation:
The amount of cubic that we need is equal to the volume of the pool therefore we just have to find the volume of the pool by using the following formula...
Volume = (Length)(Width)(Height/Depth) = (20)(10)(4) = 800
Therefore you will need 800 [tex]ft^{3}[/tex] of water to fill the pool.

Answer:
each square is 5". the base is 4x4 squares- so 20 inches square. 20x20= 400sq inches.
the semicircle at the top is 20 inches in diameter, which makes the radius 10 inches.
pi× 10^2= 314.16.
duvide that by 2 to get a semicircle- 157.8
so, the total area is the 400+ 157.8, for a total area of 557.8 square inches

A shirt boutique purchased 100 new shirts for $1072. The short-sleeved shirts cost $10 each and the long-sleeved shirts cost $12 each. How many short-sleeved shirts were purchased?
Answer:
one equation would be S+ L=36for the number of shirts sold.
Answer: 64 short-sleeved shirts were purchased.
Step-by-step explanation: (x = short-sleeved shirts. y = long-sleeved shirts.)
x + y = 100
10x + 12y = 1072
—12(x + y = 100) >>> -12x - 12y = -1200 10x + 12y = 1072 (add the equations and cancel out the 12y)
-2x/-2 (-2 cancels out) = -128/-2 (divide both by -2)
x = 64 shirts purchased for $10 each. (Hope this helped!)
(vvvThis next part doesn’t answer the question, but I should finish the equation.)
(Plug in 64 for x)>>> 64 + y = 100 (then, subtract 64 from both sides) >>> 64 - 64 = 0 (they cancel out) and 100 - 64 = 36
y = 36 shirts purchased for $12 each.
I really hope this helped! :)
The value of a house increases by 20% each year.
It is valued at $20000 today.
a) What will it be worth in two years' time?
b)What was it worth one year ago?
Answer:
a. $28,800
b. $16,000
Step-by-step explanation:
A.
20,000 * 20% = 4,000
so thats how much more it will be next year
add that together
20,000 + 4,000 = 24,000
so thats one year from now and we have to find two
multiply 20% times next years value
24,000 * 20% = 4,800
so add that to 24,000
24,000 + 4,800 = 28,800
so in two years the value will be $28,800
B.
20,000 * 20% = 4,000
so thats how much less it was worth one year ago
so you have to subtract it
20,000 - 4,000 = 16,000
so it was worth $16,000 one year ago

2,200 people enter an amusement park every hour. How long will it take for 6,000 people to enter the park?
P= Total # of people who entered the park
t= The time in hours
P=2200t
6600 = 2200t
Divide both sides of the equation by 2200:
3=t
answer : 3 hours
9515 1404 393
Answer:
2 8/11 hours ≈ 2.73 hours
Step-by-step explanation:
Assuming a constant rate, entries are proportional to time.
time/people = 1 h/(2200 people) = t/(6000 people)
t = (1 h)(6000/2200) = 2 8/11 h ≈ 2.73 h
It will take about 2.73 hours for 6000 people to enter.
