Answer:
64 softballs
Step-by-step explanation:
Coach Beard currently already has 24 softballs.
When she orders 2 more buckets with 20 in each, that's another 20 + 20 = 40 softballs added to the original 24. So, let's add these two numbers:
24 + 40 = 64
The answer is 64 softballs.

Answer:
99.7%
Step-by-step explanation:
Using the z score formula
z-score is z = (x-μ)/σ
where:
x = raw score
μ = population mean
σ = population standard deviation.
a) for x = raw score = 35
μ = population mean = 44
σ = population standard deviation =3
z = (35 - 44)/3
z = -9/3
z = -3
b) for x = raw score = 53
μ = population mean = 44
σ = population standard deviation =3
z = (53 - 44)/3
z = 9/3
z = 3
We would use the standard normal distribution table to find their probabilities
P(Z<=-3)=0.0013499
P(Z<=+3)=0.99865
So P(-3<=Z<=3)=0.99865 - 0.0013499 = 0.9973
Converting to percentage = 0.9973 × 100 = 99.73%
Therefore, the percentage of auto batteries of this brand that have a life of 35 to 53 months to one decimal place is 99.7%
There are two months that begin with the letter M (March, May)
So the probability is 2/12 = 1/6 ≈ 0.17 rounded to the nearest hundredth.

One concert performance would be $275n. The concert hall owner's profit would be the net income, after subtracting any expenses, or what the person who played the concert hall charged. Therefore, before finding the net income, the equation for the total money gained would be $275n.
