Answer:
The values of given expressions are:
1. gh = -21
2. g^2 - h = 46
3. g + h^2 = 2
4. g + h = -4
5. h - g = 10
6. g - h = -10
Step-by-step explanation:
Given values of g and h are:
g = -7
h = 3
1. gh
The two numbers are being multiplied
Putting the values
[tex]gh = (-7)(3) = -21[/tex]
2. g^2-h
Putting the values
[tex]=(-7)^2-3\\=49-3\\=46[/tex]
3. g+h^2
Putting the values
[tex]= -7 + (3)^2\\=-7+9\\=2[/tex]
4. g+h
Putting the values
[tex]= -7+3\\=-4[/tex]
5. h-g
Putting the values
[tex]= 3 - (-7)\\=3+7\\=10[/tex]
6. g-h
Putting values
[tex]=-7-3\\=-10[/tex]
Hence,
The values of given expressions are:
1. gh = -21
2. g^2 - h = 46
3. g + h^2 = 2
4. g + h = -4
5. h - g = 10
6. g - h = -10
Answer:
1) - 21
2) 46
3) 2
4) -4
5) 10
6) -10
Step-by-step explanation:
g = -7h = 3[tex]1)gh = - 7(3) \\ \: \: \: \: \: \: = - 21[/tex]
[tex]2){g}^{2} - h = ( - 7 {)}^{2} - 3 \\ \: \: \: \: \: \: \: \: \: \: \: = 49 - 3 \\ \: \: \: = 46[/tex]
[tex]3)g + {h}^{2} = - 7 + {3}^{2} \\ \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: = - 7 + 9 \\ \: \: \: \: = 2[/tex]
[tex]4)g + h = - 7 + 3 \\ \: \: \: \: \: \: \: = - 4[/tex]
[tex]5)h - g = 3 - ( - 7) \\ \: \: = 10[/tex]
[tex]6)g - h = - 7 - 3 \\ \: \: \: \: \: \: \: \: \: \: = - 10[/tex]

You currently make $18.32 an hour, get time and a half for anything over 40 hours, and a 10% commission on
all sales for the month. Determine your gross monthly salary given that your sales on average are $7,891 per
month and you work 5 hours of overtime a week.
a. $4,011.78
b. $4,132.95
C. $4,269.90
d. $4,320.12
Answer: b
Step-by-step explanation:
The correct answer is:
C) $4269.90.
Explanation:
40 hours per week at 18.32:
40*18.32 = 732.80.
Over time is time and a half; this means:
18.32*1.5=27.48 per hour overtime.
5 hours of overtime per week would be:
27.48*5=137.40.
Together this makes:
732.80+137.40=870.20 per week.
There are 4 weeks in a month;
4*870.20=3480.80.
You make 10% commission on the sales; 10% = 0.1.
0.1*7891=789.10.
Add this to the monthly income:
3480.80+789.10=4269.90.

Step-by-step explanation:
The number of adult Americans from a random sample of n adults who support a bill proposing to extend daylight savings time is a binomial random variable. Assume that its probability will be approximated using the normal distribution. Describe the area under the normal curve that will be computed in order to determine the probability that more than Americans support the bill.
Answer:
Right of X = 635.5
Step-by-step explanation:
By using the normal approximation to the Binomial random variable, we usually make use of continuity correction.
According to the rule of continuity;
P(X ≤ k) becomes P( X ≤ K + 0.5)
P(X < K) becomes P(X < K - 0.5)
P(X ≥ K) becomes P(X ≥ K - 0.5)
P(X > K) becomes P(X > K + 0.5)
P(X = K) becomes P(K - 0.5 ≤ X ≤ K + 0.5)
From the given question, Assume that we are to determine the probability that more than 635 Americans support the bill.
Then we use the > sign.
∴
P(X > K ) becomes P(X > K + 0.5)
P(X > 635) becomes P(X > 635 + 0.5)
⇒ P(X > 635.5) tot the right.
Right of X = 635.5
Which set of numbers represents the RANGE for the following table
x -3 4 6 -12
y 5 -6 2 0
A
{−6,0,2,5}
B
{4, 5, 6, 12}
C
{−3,4,6,12}
D
{0, 5, 6, 2}
Answer:
The range of the table is:
Range R = {-6, 0, 2, 5}
Hence, option A is true.
Step-by-step explanation:
Given the table
x -3 4 6 -12
y 5 -6 2 0
Determining the range:
We know that the range of a table consists of all the y-values of the given points.
From the given table, it is clear that the y-values are:
y = 5, -6, 2, 0
Thus, the range of the relation in ascending order is:
Range R = {-6, 0, 2, 5}
Please note that the duplicated elements in the range, if any, are written only once.
Therefore, the range of the table is:
Range R = {-6, 0, 2, 5}
Hence, option A is true.

A 24,000-gallon pool is being filled at a rate of 50 gallons per minute. At this rate, how many minutes
will it take to fill this pool full?
Answer: 480 minutes or 8 hours
Step-by-step explanation:
24,000 ÷ 50 = 480.
It will take 480 minutes to fill the pool.
480 minutes ÷ 60 is also 8. So it will take 8 hours to fill the pool, or 480 minutes. Whichever one you want to use.
Hope this helps!
Answer:
480 Minutes or 8 Hours
Step-by-step explanation:
If you do 24,000 divided by 50 you get a result of 480

Solve the following system of equations graphically on the set of axes below.
Y=1/3x+6 y=-5/3x-6
Answer:
I can not solve it in the system of the image, but i will give you the graph so you can copy it, or at least see how it is done.
First, we have the lines:
y = (1/3)*x + 6
y = (-5/3)*x - 6
To graph these lines, you must find two points for the lines and then draw a line that connects the points.
To do it, you can evaluate each line in two different values of x, for example for the first line we can have:
y(0) = (1/3)*0 + 6 = 6 (then we have the point (0, 6))
y(3) = (1/3)*3 + 6 = 7 (then we have the point (3, 7))
And for the second line, we will have:
y(0) = (-5/3)*0 - 6 = -6 (then we have the point (0, -6))
y(3) = -(5/3)*3 - 6 = -11 (then we have the point (-3, -11))
Now with those points we can graph the lines, and the solution of the system of equation will be the point where the two lines intersect.
The graphs of the lines are shown below:
Where the grey line is the first one, and the green is the second.
In the graph, you can see that the lines intersect in the point (-6, 4)
Then the solution for the system is x = -6, and y = 4.
Cecily is comparing two checking accounts. Checking account A has a monthly fee of $16 and a per-check fee of $0.08, while checking account B has monthly fee of $14 and a per-check fee of $0.12. She want to know how many checks she would need to write per month for the accounts to charge the same amount in fees.
Part III: What equation can be set up to solve for the number of checks Cecily would need to write per month for the accounts to charge the same amount in fees?
Part IV: How many checks would Cecily need to write per month for the accounts to charge the same amount in fees?
Part 3
Checking account A has a monthly fee of $16 and a per-check fee of $0.08
If she writes x checks, where x is some nonnegative whole number, then she is charged an additional 0.08x dollars on top of the 16 dollar fee.
The total cost of checking account A is 0.08x+16 dollars.
The total cost of account B is 0.12x dollars for similar reasoning. We don't have a monthly fee, but the cost per check is higher.
Set the two expressions equal to one another to get your answer.
Answer: 0.08x+16 = 0.12x
==============================================
Part 4
Let's solve the equation we set up in part 3
0.08x+16 = 0.12x
16 = 0.12x-0.08x
16 = 0.04x
0.04x = 16
x = 16/0.04
x = 400
If Cecily wrote 400 checks per month, then the cost of each account would be the same.
For account A, it would cost her 0.08*x+16 = 0.08*400+16 = 48 dollars
For account B, it would cost her 0.12*x = 0.12*400 = 48 dollars.
Answer: 400 checks per month
In 20 free throw attempts, Raul made 8. Based on this data, what is a reasonable estimate of the probability that Raul will make his next free throw?
Answer:
40%.
Step-by-step explanation:
Given that Raul made 8 of his 20 free throw attempts, it could be argued that he was 40% efficient on those free throws. This then 8/20 is equal to 0.40. Therefore, following this reasoning, it would be logical to say that Raul has a 40% chance of making his next shot, since that is his hitting percentage so far.
Chef Talbot is baking 6 blueberry pies. If he uses 3/4 of blueberries in each pie, how many pints of blueberries will he need??
Answer:
4 2/4 pints
Step-by-step explanation:
Well if you multiply 6 by 3/4 it equals 18/4 and if you turn that into a mixed number it will give you 4 2/4.
So in conclusion, Chef Talbot will use 4 and a half pints of blueberries.
