Answer:
1 17/40
Step-by-step explanation:
[tex]\frac{5}{8} + \frac{4}{5} \\[/tex]
Find the common denominator, which is 40
so then 5/8 = 25/40 and 4/5 = 32/40
[tex]\frac{25}{40} + \frac{32}{40} = \frac{57}{40} = 1 \frac{17}{40}[/tex]

Trevor is interested in purchasing the local hardware/sporting goods store in the small town of Dove Creek, Montana. After examining accounting records for the past several years, he found that the store has been grossing over $850 per day about 65% of the business days it is open. Estimate the probability that the store will gross over $850 for the following. (Round your answers to three decimal places.)
(a) at least 3 out of 5 business days
(b) at least 6 out of 10 business days
(c) fewer than 5 out of 10 business days
(d) fewer than 6 out of the next 20 business days If the outcome described in part (d) actually occurred, might it shake your confidence in the statement p = 0.65? Might it make you suspect that p is less than 0.65? Explain. Yes. This is unlikely to happen if the true value of p is 0.65. Yes. This is likely to happen if the true value of p is 0.65. No. This is unlikely to happen if the true value of p is 0.65. No. This is likely to happen if the true value of p is 0.65.
(e) more than 17 out of the next 20 business days If the outcome described in part (e) actually occurred, might you suspect that p is greater than 0.65? Explain. Yes. This is unlikely to happen if the true value of p is 0.65. Yes. This is likely to happen if the true value of p is 0.65. No. This is unlikely to happen if the true value of p is 0.65. No. This is likely to happen if the true value of p is 0.65.
Answer:
A) P(X ≥ 3 ) = 0.7648
B) P(X ≥ 6) = 0.7515
C) P(X < 5) = 0.0949
D) P(X < 6) = 0.00031113
Yes. This is likely to happen if the true value of p is 0.65
E) P(X ≥ 17) = 0.012118
No. This is unlikely to happen if the true value of p is 0.65
Step-by-step explanation:
Solving this question means we have to deal with binomial probability distribution which follows a formula;
P(X = x) = C(n, x) * p^(x) * (1 - p)^(n - x)
We are given p = 65% = 0.65
A) probability of getting At least 3 out of the 5 business days, we have;
P(X ≥ 3 ) = P(X = 3) + P(X = 4) + P(X = 5)
And n = 5
Thus;
P(X = 3) = C(5, 3) × 0.65³ × (1 - 0.65)^(5 - 3)
P(X = 3) = 0.3364
P(X = 4) = C(5, 4) × 0.65⁴ × (1 - 0.65)^(5 - 4)
P(X = 4) = 0.3124
P(X = 5) = C(5, 5) × 0.65^(5) × (1 - 0.65)^(5 - 5)
P(X = 5) = 0.116
Thus;
P(X ≥ 3 ) = 0.3364 + 0.3124 + 0.116
P(X ≥ 3 ) = 0.7648
B) Probability of getting at least 6 out of the 10 business days.
P(X ≥ 6) = P(X = 6) + P(X = 7) + P(X = 8) + P(X = 9) + P(X = 10)
From online binomial calculator, we have;
P(X = 6) = 0.2377
P(X = 7) = 0.2522
P(X = 8) = 0.1757
P(X = 9) = 0.0725
P(X = 10) = 0.0134
P(X ≥ 6) = 0.2377 + 0.2522 + 0.1757 + 0.0725 + 0.0134
P(X ≥ 6) = 0.7515
C) probability of getting fewer than 5 out of the 10 business days.
P(X < 5) = P(X = 4) + P(X = 3) + P(X = 2) + P(X = 1)
From online binomial calculator, we have;
P(X = 4) = 0.0689
P(X = 3) = 0.0212
P(X = 2) = 0.0043
P(X = 1) = 0.0005
P(X < 5) = 0.0689 + 0.0212 + 0.0043 + 0.0005
P(X < 5) = 0.0949
D)probability of getting fewer than 6 out of the next 20 business days;
P(X < 6) = P(X = 5) + P(X = 4) + P(X = 3) + P(X = 2) + P(X = 1)
From online binomial calculator, we have;
P(X = 5) = 0.000261
P(X = 4) = 0.000044
P(X = 3) = 0.0000056
P(X = 2) = 0.0000005
P(X = 1) = 0.00000003
P(X < 6) = 0.000261 + 0.000044 + 0.0000056 + 0.0000005 + 0.00000003
P(X < 6) = 0.00031113
Yes, in this scenario, It is likely to happen and I would think p is less than 0.65 because probability is less than 1 out of 1000.
E) probability of getting more than 17 out of the next 20 business days.
P(X ≥ 17) = P(X = 18) + P(X = 19) + P(X = 20)
From online binomial calculator, we have;
P(X = 18) = 0.0099846
P(X = 19) = 0.00195187
P(X = 20) = 0.00018125
P(X ≥ 17) = 0.0099846 + 0.00195187 + 0.00018125
P(X ≥ 17) = 0.012118
Probability is around 12 in 100 and not up to 50%. Thus, This is unlikely to happen if the true value of p is 0.65

Determine if the ordered pair (-4,3) is a solution of
4x - y = -13
Show ALL your work here
Answer:
This is NOT a solution
Step-by-step explanation:
If we plug in the coordinates (-4,3) into 4x-y our new equation is 4×-4-3 and if we solve this equation.... 4×-4=-16 and -16-3=-19 which does NOT equal to -13

Answer:
The first is 26 and the second is 6
He earns $25 per hour for training and $15 per hour for data entry support. Steven can work no more
than 40 hours a week. He wants to use linear programming techniques to optimize his income.
Part A
Construct a model to represent the amount of time Steven can spend on data entry and training. Be sure
to define your variables. Sketch a graph of your model.
Part B
While Steven would like to spend most of his time training, the number of hours spent training cannot
exceed twice the number of hours doing data entry support. Steven must spend at least 10 hours each
week on data support. Construct a model to show the constraints. Sketch a graph of your model.
Part C
Find the vertices of the feasible region. Show your work or explain how you found the coordinates.
Part D
What is the maximum possible amount of money Steven can earn in a week given the constraints? Round
to the nearest dollar. Validate your solution to assess the reasonableness of you
Part E
The number of hours Steven worked one week resulted in a gross income of $800. From this, a portion was
withheld for benefits, retirement, and taxes. The total amount withheld from Steven’s check was $264.
The amount withheld for taxes was twice the amount withheld for retirement, and the amount withheld
for benefits was $24 less than the sum of retirement and taxes. Construct a system of equations that can
be used to find the amount of benefits, retirement, and taxes. Be sure to define your variables.
Part F
Solve the system from Part E. Validate your solution to assess the reasonableness of your model.

Isaac buys 17 anti-pollution masks for £5.25 each.
He pays with five £20 notes.
a) How much change should Isaac get?
Write your answer in £.
The normal price of an e-scooter is £370
In a sale, there is 1 off the normal price of the e-scooter.
b) Work out the price of the e-scooter in the sale.
Write your answer in £.
Answer:
A) Isaac should get £ 10.75 in change.
B) The price of the e-scooter in the sale is £ 366.3.
Step-by-step explanation:
A) Given that Isaac buys 17 anti-pollution masks for £ 5.25 each, and he pays with five £ 20 notes, to determine how much change Isaac should get, the following calculation must be performed:
(20 x 5) - (17 x 5.25) = X
100 - 89.25 = X
10.75 = X
So Isaac should get £ 10.75 in change.
B) Given that the normal price of an e-scooter is £ 370 and, in a sale, there is 1 off the normal price of the e-scooter, to determine the price of the e-scooter in the sale the following calculation must be performed:
370 - (370 x 0.01) = X
370 - 3.7 = X
366.3 = X
Thus, the price of the e-scooter in the sale is £ 366.3.

When finding the area of something, you multiply. And in this case, you are multiplying the base (471.5 ft) by the height (21.3 ft).
If f(x) = -x + 5 and g(x) = 3x + 2, Find f(2)*g(2).
Answer:
24
Step-by-step explanation:
To find f(#) or g(#), plug the number into each x of the equation.
f(x) = -x + 5
f(2) = -(2) + 5
Simplify the parentheses by multiplying.
f(2) = -2 + 5
Add.
f(2) = 3
g(x) = 3x + 2
g(2) = 3(2) + 2
Simplify the parentheses by multiplying.
g(2) = 6 + 2
Add.
g(2) = 8
Now they are asking you to multiply
f(2) • g(2)
3 • 8
= 24
