While negotiating to have a new facility built in Sheboygan, Wisconsin, a company promises to hire 700 workers initially, and then hire an additional 50 workers every four months. Write a linear equation that describes the number of employees (y) in terms of
the number of years after the initial hires are made (x).
What is the correct equation?
Answer:
y= 700 + 150x
Step-by-step explanation:
Since they hire 50 employees every 4 months, that's 150 new employees per year, plus the initial 700. So, you multiply 150 by the number of years, add 700 to that, and it equals y.
2400 people attended a football game. 1728 of the people attending supported the home team, while 672 supported the visiting team. What percentage of people attending supported the home team?
Answer:
Percentage= 72%
Step-by-step explanation:
Giving the following information:
Total population= 2,400
People supporting the local team= 1,728
To calculate the percentage of people supporting the local team, we need to use the following formula:
Percentage= (people supporting / total population)*100
Percentage= (1,728/2,400)*100
Percentage= 72%

you would make the percentage a decimal and times that by how many problems.
Answer:
24 problems
Step-by-step explanation:
I like to do it like this: I find out what 10 percent is, so I divide it by 10. 30/10=3. 10 percent plus 10 percent is 20 percent. That's 6. 100 percent minus 20 is 80 percent. 30 - 6 is 24. Hope this helps.

Step-by-step explanation:
An object is moving at a speed of 230 feet per week. Express this speed in inches per
minute. Round your answer to the nearest hundredth.
Answer:
Step-by-step explanation:
0.27 inches per minute....
An object is moving at a speed of 230 feet per week. This speed in inches per minute will be 0.27.
We know ,
1 feet = 12 inches and
1 week= 7days = 24×7 hours = 24×7×60 min.
= 10080 min.
Now, we just need to be careful with our multiplication and division. So we are going to have 230 times 12 on top divided by 24 times 7 times 60 i.e., 10,080 on bottom.
230 feet per week in inches per min = 230×12/10,080.
After evaluating and rounding up to 2 decimal places or the hundredth place , we will get our answer i.e., 0.27 inches/min.

Ken has an investment account which compounds interest continuously at a rate of 3.4%. After 4 years, he has $4400 in the account. How much money did he initially place in the account? Round your answer to the nearest dollar. Do NOT round until you have calculated the final answer.
Answer:
$6617
Step-by-step explanation:
Use the formula for calculating compound interest A=P0ert where A is the unknown, P0=4400, r=0.034, and t=12. Substitute the values into the formula and simplify.
A=4400e0.034⋅12
A=4400e0.408
A=4400(1.503...)
A=6616.75
After 12 years, there will be A≈6617 in the account, rounded to the nearest dollar.

Answer:
-8
Step-by-step explanation:
Using the algebraic expression 4n + 6, what is the greatest whole-number value that will give you a result less than 100?
Answer:
23
Step-by-step explanation:
Allow 4n+6=100
∴4n=94
∴n=23.5
If 23.5 gives you 100 exactly, the greatest whole number that'll give you a result less than 100 is 23.
The claim is that the standard deviation of the speeds of drivers in Bradford is 8 mph. An experienced driver feels that this is very low. If a random speed check is conducted for 50 drivers, the standard deviation is 10.5 mph. Can we reject the null at
Answer:
Null hypothesis is rejected. Standard deviation is > 8 miles per hour
Step-by-step explanation:
σ [Population standard deviation] = 8 , s [sample standard deviation] = s
n [no of items] = 8
H0 [Null] : σ = 8 ; H1 [Alternate - Right Tail] : σ > 8
χ2 = (n - 1) . s^2 / σ^2
= 49 x (10.5)^2 / 82 = 5402.25 / 64
χ2 = 84.410
df [degree of freedom] = n -1 = 50 - 1 = 49
P value (χ^2 49 > 84.410) = 0.00125
p = 0.0013
p < α ie 0.05
So, H0 is rejected
Hence we state that standard deviation is > 8 miles per hpur
