At the time 4 PM will it be after they each have worked 4 shifts. Option E is correct.
What exactly is simplification?Simplifying means making something easier to do or comprehend, as well as making something less difficult.
Mashud and Iqbal are security guards at a top-secret federal vault. They each work 8-hour shifts, If Mashud begins his shift at 8 PM,
The time will it be after they each have worked 4 shifts;
8 PM + 8 hour =4 AM
4 AM + 8 hour = 12 PM
12 PM+ 8 hour =8 PM
8 PM + 8 hour = 4 PM
Hence, option E is correct.
They will each have worked four shifts by the time it is 8 PM.

Solve the equation 34 - (x + 8) = 6x-2
Answers
Answer:
x = 4
Step-by-step explanation:
To solve the equation, we would have to solve for the variable x.
34 - (x + 8) = 6x - 2
Remove the parentheses.
34 - x - 8 = 6x - 2
Add 2 to both sides and combine like terms.
28 - x = 6x
Add x to both sides.
28 = 7x
Swap sides.
7x = 28
Divide both sides by 7.
x = 4
So the solution to the equation would be x = 4

Bobby can work at most 20 hours next week, but she needs to earn at least $150. Herdog-walking job pays her $6 per hour and her iob as a car wash attendant pays her $10 perhour. If d is the number of hours she walks dogs this week and w is the number of hours sheworks at the car wash, write a system of inequalities that represents Bobby's situation.
Answers
Solution:
Let d represent the number of hours Bobby walks dogs,
and w be the number of hours she works at the car wash.
Given that she can work at most 20 hours next week, this implies that the total number of hours she works is expressed as
\(d+w\leq20\)If her dog-walking job pays her $6 per hour, this implies that for d number of hours, she will earn
\(\begin{gathered} \frac{\$6}{1\text{ hour}}\times d\text{ hours} \\ =\$\text{ 6d} \end{gathered}\)and her iob as a car wash attendant pays her $10 per hour, similarly for w number of hours, she will earn
\(\begin{gathered} \frac{\$10}{1\text{ hour}}\times w\text{ hours} \\ =\$10w \end{gathered}\)Given that she needs to earn at least $150, this implies that her total earnings will be expressed as
\(6d+10w\ge150\)Hence, the system of inequalities that represents Bobby's situation is:
\(\begin{gathered} d+w\leq20 \\ 6d+10w\ge150 \end{gathered}\)Customer pays $0.035 per minute for local calls, if the customer made 60 local calls that all lasted 3 minutes, how much will the customer pay?
Answers
The customer will pay $6.30 for the 60 local calls that all lasted 3 minutes.
To find out how much the customer will pay, we need to calculate the total cost for all the local calls.
Step 1: Calculate the total number of minutes for all the calls
Since the customer made 60 local calls and each call lasted 3 minutes, we can multiply 60 by 3 to get the total number of minutes.
60 calls * 3 minutes/call = 180 minutes
Step 2: Calculate the total cost for all the minutes
The customer pays $0.035 per minute for local calls. To find the total cost, we can multiply the total number of minutes by the cost per minute.
180 minutes * $0.035/minute = $6.30

If f (x) = -9x - 9 and g (x) = Vx - 9, what is (f ° g) (10)?

Answers
The biker needs to travel 45 km more to complete his journey.
Given that, a biker traveled 2/5 of the road on the first day, then traveled 5 kilometers less on the next day, which is equal to 3/8 of the road, we need to find how much he need to cover more,
Let the total distance of the road be x,
So,
2x/5 - 5 = 3x/8
2x/5 - 3x/8 = 5
Solving for x,
Multiply by 40 to both sides,
16x-15x = 200
x = 200
Therefore, the total distance of the road is 200 km.
Since, he travelled =
200 (2/5) = 80 km + 200 (3/8) = 75 km = 155 km
Therefore, he needs to travel 200-155 = 45 km more.
Hence, the biker needs to travel 45 km more to complete his journey.

When ordering a list of numbers by hand, it is convenient to convert them to the same form. Decimal equivalents are easily found using a calculator.
OrderThe attachment shows the ordering, least to greatest, to be ...
\(\dfrac{28}{9}.\ \sqrt{19},\ \sqrt[3]{88}\)
__
Additional comment
We know that √19 > √16 = 4, and ∛88 > ∛64 = 4, so the fraction 28/9 will be the smallest. That leaves us to compare √19 and ∛88, both of which are near the same value between 4 and 5.
One way to do the comparison is to convert these to values that need to have the same root:
√19 = 19^(1/2) = 19^(3/6) = sixthroot(19³)
∛88 = 88^(1/3) = 88^(2/6) = sixthroot(88²)
The roots will have the same ordering as 19³ and 88².
Of course, these values can be found easily using a calculator, as can the original roots. By hand, we might compute them as ...
19³ = (20 -1)³ = 20³ -3(20²) +3(20) -1 = 8000 -1200 +60 -1 = 6859
88² = (90 -2)² = 90² -2(2)(90) +2² = 8100 -360 +4 = 7744
Then the ordering is ...
28/9 < 19³ < 88² ⇒ 28/9 < √19 < ∛88
Answer:
the ordering is
28/9 < 19³ < 88² ⇒ 28/9 < √19 < ∛88

A sample of 150 college students reports sleeping an average of 6.4 hours on weeknights, with a standard error of 0.17 hours.
Question: Find a 95% confidence interval for the true average number of hours of sleep college students get on weeknights. Show your work here.
Interpret your 95% confidence interval in context of the situation.
Answers
a) A 95% confidence interval for the true average number of hours of sleep college students get on weeknights, using the lower and upper limits from a t-distribution table, is [6.07, 6.73] hours.
b) Based on the given sample, we can be 95% confident that the true average number of hours of sleep college students get on weeknights is between 6.07 and 6.73 hours.
What are the lower and upper limits of a 95% confidence interval?The lower and upper limits of a 95% confidence interval obtained from the t-distribution table can be computed as follows:
Lower limit = Sample Mean - T-value for CL x Estimated Standard Error of the mean
Upper limit = Sample Mean + T-value for CL x Estimated Standard Error of the mean
The sample size = 150
The sample mean = 6.4 hours
The standard error = 0.17 hours
The t-value for a 95% confidence level and 149 degrees of freedom, using a t-distribution calculator or a table = 1.976.
Lower limit = 6.4 - (1.976) (0.17)
= 6.07 hours
Upper limit = 6.4 + (1.976) (0.17)
= 6.73 hours
Thus, on average, college students sleep on weeknights between 6.07 and 6.73 hours.

According to the logarithmic regression model, when will the US population be 400 million?
Answers
The logarithmic regression equation that models the situation is given as follows:
y = 242.9037 + 23.7097ln(x).
The estimated population in 2010 is of:
313.9 million
Which overestimates the actual amount by 5.2 million.
The prediction for when the population will be of 400 million is of:
Year of 2,744.
How to obtain the logarithmic regression equation?The logarithmic regression equation is obtained inserting the points of the data-set into a logarithmic regression calculator.
From the table given by the image at the end of the answer, the points are given as follows:
(0, 248.8), (10, 281.4), (20, 308.7), (30, 331.4), (31, 331.9).
Inserting these points into a calculator, the equation is given as follows:
y = 242.9037 + 23.7097ln(x).
2010 is 20 years after 1990, hence the estimate is given as follows:
y = 242.9037 + 23.7097 x ln(20) = 313.9 million.
The overestimate of the actual value, from the table, is of:
313.9 - 308.7 = 5.2 million.
The prediction for when the population will be of 400 million is obtained as follows:
400 = 242.9037 + 23.7097 x ln(x)
ln(x) = (400 - 242.9037)/23.7097
ln(x) = 6.6258.
x = e^(6.6258)
x = 754.
Hence during the year of 2,744.

(x, y) = (-1, 9)
Explanations:Given the system of equations expressed as:
4x + 8y = 68 .......................... 1
-12x + 3y = 39 ......................... 2
Using elimination method
Multiply equation 1 by 3 and equation 2 by 1 to eliminate the "x" variable as shown:
4x + 8y =68 ........................ 1 * 3
-12x + 3y = 39 .................... 2 * 1
___________________________________
12x + 24y = 204
-12x +3y = 39
Add the resulting equations to have;
24y + 3y = 204 + 39
27y = 243
y = 243/27
y = 9
Substitute y = 9 into equation 1 to solve for "x". From equation 1;
4x + 8y = 68
4x + 8(9) = 68
4x + 72 = 68
4x = 68 - 72
4x = -4
x = -4/4
x = -1
Therefore the solution to the system of equation is (-1, 9)
