Anthony currently earns $11.75 per hour.
• He will get a $0.25 raise after 6 months.
• He will get a 2.5% raise after an additional 6 months.
After Anthony gets both raises, what will his pay be for 38 hours of work?
Answer:
$467.40
Step-by-step explanation:
well if you take his original pay (11.75) and add 0.25, you get 12.00 per hour.
12.00 + 2.5% raise would be:
12.00 + 0.3 or 30 cents, so the pay per hour is 12.30.
then take 12.30 x 38 and you should get $467.40
so after both raises, and 38 hours of work, he will earn $467.40

Calculate for y given that mean of 20,2y,25,y,30 is 27
Answer:
y = 218
Step-by-step explanation:
Mean = (Sum of all numbers)/(How many numbers present)
27 = (20 + 2y + 25 + y + 30)/27
27 = (3y + 75)/27
3y + 75 = 729
3y = 729 - 75
3y = 654
y = 218

What is the z* critical value for constructing a 99% confidence interval for a proportion?
Find the z-table here.
1.65
1.96
2.33
2.58
Answer:
2.576
Step-by-step explanation:
The Z critical value for constructing a 99% confidence interval for a proportion is 2.58.
What is a z-score?A z-score measures exactly how many standard deviations a data point is above or below the mean. It allows us to calculate the probability of a score occurring within our normal distribution and enables us to compare two scores that are from different normal distributions.
For the given situation,
The confidence interval for a proportion = 99% = 0.99
Area to the left of a positive Z score in this standard normal distribution table is
⇒ [tex]\frac{1+confidence level}{2}[/tex]
⇒ [tex]\frac{1+0.99}{2}[/tex]
⇒ [tex]\frac{1.99}{2}[/tex]
⇒ [tex]0.995[/tex]
The corresponding Z score in the table for 0.995 is
⇒ [tex]2.5+0.08[/tex]
⇒ [tex]2.58[/tex]
Hence we can conclude that the Z critical value for constructing a 99% confidence interval for a proportion is 2.58.

Will mark brainliest for area.
Answer:
c
Step-by-step explanation:
first, find the area of the rectangle thing,
A = lw
14 x 8
112
but, there is a semicircle in it so you need to subtract that from it:
A = πr^2/2
A = π(4)^2/2
A = π16/2
A = 8π
A ≈ 25.132741228718346
then subtract that area from the area of the rectangle:
112 - 25.132741228718346
86.867258771281654
or about 89.9
