Ali starts working on an annual salary of $20 000. His contract will give him an increase of $120 every 6 months. If he keeps working for 15 years, how much will Ali earn?
Answer: 23,600

a fishing boat accidentally spills 15 barrels of diesel oil into the ocean. each barrel contains 42 gallons. if the oil film on the ocean is 2.5 x 102 nm thick, how much area in square meters will the oil slick cover? assume 1 gal
The area in square meters will the oil slick cover is 9.5×10⁶ m².
15 barrels of diesel spilt into the ocean, where each barrel contains 42 gallons. Thereby the total volume of the oil spilt by 15 barrels is calculated as follows:
The total volume of the oil spilt by 15 barrels = 15× 42 gallons.
=630 gallons
1 gallon = 3.78541 liters
Volume in L = 630 gallons × 3.78541 liters/ 1 gallon
= 2384.8083 L
1 L = 10⁻³ m³
2384.8083 L = 2384.8083 × 10⁻³ m³
= 2.3848083 m³
The area covered by the oil spill has to be determined, where the thickness of the oil spill is given to be 2.5×10² nm.
1 nm = 10⁻⁹ m
Thereby, 2.5×10² nm = 2.5×10²×10⁻⁹ m
= 2.5×10⁻⁷ m
Area (m²) = volume (m³)/thickness (m)
= 2.3848083 m³/ 2.5×10⁻⁷ m
= 0.95392×10⁷ m²
= 9.5×10⁶ m²

the weights (in pounds) of three adult males are 160, 215, and 195. what is the standard error of the mean for these data?
The standard error of the mean for these data is 13.14 pounds..
The standard error of the mean (SEM) is a measure of the variability of the sample mean. It is calculated as the standard deviation of the sample divided by the square root of the sample size.
To find the SEM for the given data, we first need to calculate the sample mean:
(160 + 215 + 195) / 3 = 190
Then we need to calculate the deviation of each value from the mean:
160 - 190 = -30
215 - 190 = 25
195 - 190= 5
Next, we need to square these deviations:
(-30)² = 900
25² = 625
5² = 25
Next, we need to calculate the variance:
(900 + 625 + 25) / 3 = 516 2/3
Then we need to calculate the standard deviation:
√(516 2/3) = 22.73
Finally, we can calculate the standard error of the mean:
22.73 / √(3) = 13.14
So, the standard error of the mean for these data is 13.14 pounds.

A recent survey was conducted to compare the cost of solar energy to the cost of gas or electric energy. Results of the survey revealed that the distribution of the amount of the monthly utility bill of a 3-bedroom house using gas or electric energy had a mean of $91 and a standard deviation of $8. If the distribution can be considered mound-shaped and symmetric, what percentage of homes will have a monthly utility bill of more than $83?
Answer:
Using a standard normal distribution table, we can find that the percentage of homes that have a monthly utility bill of more than $83 is approximately 13.6%.
Step-by-step explanation:
If the distribution of the monthly utility bill for gas or electric energy can be considered mound-shaped and symmetric, we can use the standard normal distribution table to find the percentage of homes that have a monthly utility bill of more than $83.
To use the standard normal distribution table, we need to standardize the variable by subtracting the mean and dividing by the standard deviation:
(83 - 91) / 8 = -0.875
This means that a monthly utility bill of $83 is 0.875 standard deviations below the mean.
Using a standard normal distribution table, we can find that the percentage of homes that have a monthly utility bill of more than $83 is approximately 13.6%.

The solution of the system of equations:

is the point (-4, 1).
How to solve the system of equations?Here we want to solve the system of equations below:
-2x - 10y = -2
-4y = x
By the substitution method, to do so, we need to isolate one of the variables in one of the equations and then replace that in the other equation.
We can see that x = -4y is already isolated on the second equation, then we can replace this on the first one to get:
-2*(-4y) - 10y = -2
We can solve this for y.
8y - 10y = -2
-2y = -2
y = -2/-2 = 1

The correct answer for equivalent interest rate and no. of times will the money be compounded is C) 1.5% and 16 times respectively.
The annual interest rate of 6% is equivalent to a quarterly interest rate of 6% / 4 = 1.5%. The money will be compounded quarterly, so it will be compounded 16 times in total over 4 years.
Compound interest is computed as interest on the initial principal plus any accrued interest from prior periods. Money multiplies more quickly thanks to compounding, and the more compounding periods there are, the higher the compound interest will be.

At a local play, student tickets cost $5 each and adult tickets cost $11 each. if ticket sales were $3,000 for 300 tickets, how many students attended the play? a. 50 b. 150 c. 250d. 300
This problem can be solved used linear equations. Here there are two variables, number of students and number of adults. After calculations we get the number of students attended the play is 50.
Lets consider the number of students is x and number of adults is y.
Total tickets sold = 300
x + y = 300 ------------ equation 1
The amount of total tickets sold is 3000.
Amount sold to students = 5x
Amount sold to adults = 11y
So, 5x+11y =3000 ----------- equation 2
Equating the x term for equation 1
Multiplying both sides with 5
5 (x+y) = 5 × 300
5x + 5y = 1500 ---------- equation 3
Subtracting equation 3 from equation 2
5x + 11y = 3000
- ( 5x + 5y = 1500)
6y = 1500
y = 1500/6 = 250
Number of adult attended = 250
From equation 1, x+y = 300
Substituting the value of y
x + 250 = 300
x = 300-250 = 50
So number of students attended is 50

work and explain your reasoning.

Palisade Bakery is a better buy than Union City Bakery.
To determine which bakery has the better buy, we need to calculate the cost per muffin at each bakery. It is determined by dividing the total cost by total number of muffins. Assuming one batch has ten muffin as not mentioned.
Union City Bakery: $10.00 / 3 batches = $3.33 per batch (approx)
= $3.33/ 10
= $0.33 per muffin
Palisade Bakery: $6.25 / 20 muffins = $0.31 per muffin
Based on this calculation, Palisade Bakery has the better buy as each muffin costs $0.31, which is cheaper than the cost per muffin at Union City Bakery, which is approximately $0.33 per muffin.
