Step-by-step explanation:
Bob needs his refrigerator fixed. The repairman will charge Bob a flat fee of $40 plus an additional $15 for each hour he needs to work on it. Write an equation to represent Bob's cost to repair his refrigerator. Use y for the total cost and x for hours.
Given:
Fixed fee = $40
Additional fee = $15 per hour
To find:
The equation to represent Bob's cost to repair his refrigerator.
Solution:
Let y be the total cost for x hours.
Additional fee for one hour = $15
Additional fee for x hour = $15x
Total cost = Fixed fee + Additional fee
[tex]y=40+15x[/tex]
Therefore, the required equation is [tex]y=40+15x[/tex].

The sum of two numbers is 32 their difference is 10. Find the numbers.
The two numbers are: 21 and 11
Step-by-step explanation:
Let x and y be the two numbers.
x+y = 32
x-y = 10 Rewrite this as x = y+10 and substitute for x in the first equation.
(y+10) + y = 32 Simplify and solve for y.
2y+10 = 32 Subtract 10 from both sides.
2y = 22 Divide both sides by 2.
y = 11
x = y+10
x = 11+10
x = 21
Answer:
y = 11
Step-by-step explanation:
x + y = 32
10 + y + y = 32
10 + 2y = 32
2y = 22
y = 11

The EPA wants to know the daily level of pollutant discharge in the manufacturing district in Pittsburgh for February 2005. The monitoring equipment reveals that the mean daily discharge per factory (calculated as total areal discharge divided by total areal factories) is 30.2 tons with a standard deviation of 9.1 tons. Construct a confidence interval for the true population mean of pollutant discharge using a 95% level of confidence.
Answer:
The 95% confidence interval for the true population mean of pollutant discharge is (26.7 tons, 33.7 tons).
Step-by-step explanation:
Let X represent the daily level of pollutant discharge in the manufacturing district in Pittsburgh.
The monitoring equipment reveals that for the 28 days of the February month
Mean daily discharge per factory, ([tex]\bar x[/tex]) = 30.2 tons
Standard deviation daily discharge per factory, (s) = 9.1 tons
Compute the critical value of t for 95% level of confidence and (n - 1 =) 27 degrees of freedom as follows:
[tex]t_{0.05/2, 27}=2.052[/tex]
*Use a t-table.
Compute the 95% confidence interval for the true population mean of pollutant discharge as follows:
[tex]CI=\bar x\pm t_{\alpha/2, (n-1)}\cdot\frac{s}{\sqrt{n}}[/tex]
[tex]=30.2\pm 2.052\times\frac{9.1}{\sqrt{28}}\\\\=30.2\pm 3.53\\\\=(26.67, 33.73)\\\\\approx (26.7, 33.7)[/tex]
Thus, the 95% confidence interval for the true population mean of pollutant discharge is (26.7 tons, 33.7 tons).

If the fraction (352/x-10) is equivalent to -22, find the value of x.
Answer:
The value of x is -6
Step-by-step explanation:
Let us equate the fraction by its equivalent
∵ [tex]\frac{352}{x-10}[/tex] = -22
→ Multiply both sides by (x - 10) to cancel the denominator of the left side
∴ [tex]\frac{352}{x-10}[/tex] × (x - 10) = -22 × (x - 10)
∴ 352 = -22(x - 10)
→ Simplify the right side by multiplying -22 by the bracket (x - 10)
∵ 352 = -22(x) - 22(-10)
∴ 352 = -22x + 220
→ Add 22x to both sides
∵ 22x + 352 = -22x + 22x + 220
∴ 22x + 352 = 220
→ Subtract 352 from both sides
∴ 22x + 352 - 352 = 220 - 352
∴ 22x = - 132
→ Divide both sides by 22 to find x
∴ [tex]\frac{22x}{22}=-\frac{132}{22}[/tex]
∴ x = -6
∴ The value of x is -6

The lateral surface area of a cube is 400cm². Its total surface area is
_______
a)600cm² b) 2400cm² c) 500cm² d) 650cm²
Answer:
Step-by-step explanation:
Lateral surface area of cube = 4a²
4a² = 400
a² = 400÷4
a² = 100
a = √100 = √10*10
a = 10 cm
Total surface area = 6a²
= 6 * 10²
= 6* 100
= 600 cm²

Answer:
D. -3 and 3
Step-by-step explanation:
We are given an output of 2. This means this is the value we need an input for. We need to find a number(s) that lie on the x axis and when we move up, you get an output of 2.
Option A:
If we are given an input of -2, we start at (-2, 0) and move up until we reach a point on the line. We end up lying on the point (-2, 3). Thus, the output for having an input of -2 is 3 which proves that this answer is incorrect.
Option B:
As stated above -2 has an output of 3 which is wrong. Since we know this, we can eliminate this as an option.
Option C:
If we are given an input of -3, we start at (-3, 0) and move up until we reach a point on the line. We end up lying on the point (-3, 2). Thus, the output for having an input of -2 is 2 which proves that this answer is correct.
Option D:
We know that -3 is a possible input so we just need to check 3 as an input.
If we are given an input of 3, we start at (3, 0) and move up until we reach a point on the line. We end up lying on the point (3, 2). Thus, the output for having an input of 3 is 2 which proves that this answer is also correct.
Since we know that -3 and 3 are possible inputs for an output of 2 on the graph, we need to include them both in our answer. Thus, the answer is D.

A pension fund manager is considering three mutual funds. The first is a stock fund, the second is a long-term government and corporate bond fund, and the third is a T-bill money market fund that yields a sure rate of 4.2%. The probability distributions of the risky funds are: Expected Return Standard Deviation Stock fund (S) 12 % 33 % Bond fund (B) 5 % 26 % The correlation between the fund returns is .0308. Suppose now that your portfolio must yield an expected return of 11% and be efficient, that is, on the best feasible CAL. a. What is the standard deviation of your portfolio? (Do n
Answer:
28.63%
Step-by-step explanation:
Given data:
correlation between funds = 0.308
Risk-free rate = 0.042
Expected return rate = 0.11
Calculate the standard deviation of the new portfolio
standard deviation of portfolio = ( weight of risky assets )* (standard deviation of optimal risky portfolio )
weight of risky assets = (expected return - risk-free rate) / ( expected return of optimal portfolio - risk-free rate ) ( calculated using excel spreadsheet)
= 0.9696
Standard deviation of optimal risky portfolio = 29.525489% ( calculated using excel spreadsheet )
hence standard deviation of portfolio that would an expected return of 11%
= 0.9696 * 29.525489%
= 28.63%

Step-by-step explanation:
Daniela, Kieu, and Cameron decide to go to the movies one hot summer afternoon. The theater is having a summer special called Three Go Free. They will get free movie tickets if they each buy a large popcorn and a large soft drink. They take the deal and spend a total of $22.50 on large popcorns and soft drinks. The next week, they go back again, only this time, they each pay $8 for a ticket, they each get a large soft drink, but they share one large bucket of popcorn. This return trip costs them a total of$37.50. Use systems of equations to find the price of a large soft drink and the price of a large bucket of popcorn!
Answer:
Price of a large soft drink = $3
Price of large bucket of popcorn = $4.5
Step-by-step explanation:
Let the cost of one large popcorn = $P
And the cost of one large soft drink = $S
If Daniela, Kieu and Cameron avail the deal of Three Go Free,
3P + 3S = 22.50
P + S = 7.5 -----(1)
Next time they each pay $8 for a ticket, they each get a large soft drink but they share one large bucket of popcorn.
This trip cost them = $37.50
Cost of 3 tickets + Cost of 3 large soft drinks + Cost of one large bucket of popcorn = 37.50
(3 × 8) + (3 × S) + P = 37.5
24 + 3S + P = 37.5
3S + P = 13.5 -----(2)
By subtracting equation (1) from equation (2),
(3S + P) - (P + S) = 13.5 - 7.5
2S = 6
S = $3
From equation (1),
P + 3 = 7.5
P = $4.5
Therefore, price of a large soft drink is $3 and a large bucket of popcorn is $4.5
