An executive invests 29,000, some at 8% and the rest at 7% annual interest. If he receives an annual return of $2,230, how much is invested at each rate?
Answers
Answer:
Amount invested in A (8%) = $20,000
Amount invested in B (7%) = $9,000
Step-by-step explanation:
Given:
Total amount invested = $29,000
Interest rate A = 8% = 0.08
Interest rate B = 7% = 0.07
Annual return = $2,230
Find:
Amount invested in each
Computation:
Assume;
Amount invested in A = x
Amount invested in B = 29,000 - x
So,
Interest receive from A = x × 0.08
Interest receive from A = 0.08 x
Interest receive from B = (29000 - x) × 0.07
Interest receive from B = 2,030 - 0.07 x
Annual return = Interest receive from A + Interest receive from B
2,230 = 0.08 x + 2,030 - 0.07 x
x = 20,000
Amount invested in A = $20,000
Amount invested in B = 29,000 - $20,000
Amount invested in B = $9,000

A $40

Answers
The cost of the first lesson based on the information is E. $80.
How to calculate the cost?From the information, the cost of the first lesson is twice the cost of each additional lesson. Let the others lesson b represented by x.
The first lesson will be: = 2 × x = 2x
Since there are 8 lessons, this will be:
First lesson + Other lesson = Cost
2x + (7 × x) = 360
2x + 7x = 360
9x = 360
Divide
x = 360/9
x = 40
Therefore, first lesson will be:
= 2x
= 2 × 40

Answers
(a) The probability of a failure given there are more than 1,000 wells in a geological formation is 0.1001.
(b) The probability of a failure given there are fewer than 500 wells in a geological formation is 0.0852.
(a) We have to determine the probability of a failure given there are more than 1,000 wells in a geological formation.
P(B∣A) = Total number of failed wells more than 1000 wells/Total number of wells with 1000 failed wells
P(B∣A) = (180 + 443 + 60)/(1685 + 3733 + 1403)
P(B∣A) = 683/6821
P(B∣A) = 0.1001
(b) We have to determine the probability of a failure given there are fewer than 500 wells in a geological formation.
P(B∣C) = Number of failed well/Number of failed wells with total less that 500 wells
P(B∣C) = (2 + 14 + 44 + 3)/(28 + 363 + 309 + 39)
P(B∣C) = 63/739

E. A report by a company that manufactures hair brushes says 56% of people who buy their brushes own only one hair brush. The conclusion comes from a survey of 500 males who bought the company's brush.
Step-by-step explanation:
These two are the biased reports because they don't include the full population.
C is biased because it only includes teens, not people of any other age.
E is biased because it only included males, not females.
A isn't biased because it includes the stated population, high school students in the city.
B isn't biased because the sample was of 50 random customers, which is the general population.
D isn't biased as it included all data from the website.
Hope this helps!
The solution is,:
1) A clothing store claims that 45% of its customers prefer skinny jeans over regular jeans. They concluded this from a survey which asked 120 randomly selected teenage customers which style they prefer.
3) A report by a company that manufactures hair brushes says 56% of people who buy their brushes own only one hair brush. The conclusion comes from a survey of 500 males who bought the company's brush.
What is sample and statistic?A portion of population taken and analyzed to predict information about population is called sample of that population.

Those numbers who summarize information about sample are called statistic.

The impact on Carns’s income from eliminating the Small Tools Division would be: Multiple Choice
Answers
The impact on Carns Company's income from eliminating the Small Tools Division would be a decrease of $1,209,000.
To determine the impact on Carns Company's income from eliminating the Small Tools Division, we need to consider the avoidable costs associated with the division.
The avoidable costs include all of the variable costs of the division and a portion of the fixed costs that are specifically related to the Small Tools Division. In this case, the variable costs of the division are $1,295,000, and $119,000 of the fixed costs are avoidable.
To calculate the impact on income, we subtract the avoidable costs from the loss reported by the division:
Impact on income = Loss - Avoidable costs
Impact on income = $205,000 - ($1,295,000 + $119,000)
Impact on income = $205,000 - $1,414,000
Impact on income = -$1,209,000
The negative sign indicates a decrease in income.

The slope of a line perpendicular to the line whose equation is x - 2y = -8 is -2.
What are perpendicular lines?In Mathematics and Geometry, perpendicular lines are two (2) lines that intersect or meet each other at an angle of 90° (right angles).
From the information provided above, the slope for the equation of line m is given by:
x - 2y = -8
2y = x + 8
y = x/2 + 4
slope (m) of line m = 1/2
In Mathematics and Geometry, a condition that is true for two lines to be perpendicular is given by:

A manufacturer has 576 square inches of material available to construct the 6 faces of a carton, which will be in the shape of a rectangular prism. To maximize the volume, the carton will have dimensions such that the length and width are each twice the height.
Answers
To maximize the volume, of the rectangular prism, the carton should have dimensions of approximately 10.74 inches (length), 10.74 inches (width), and 5.37 inches (height).
What is the dimension required to maximize the volume of the box?Assuming the height of the rectangular prism is h inches.
According to the given information, the length and width of the prism will be twice the height, which means the length is 2h inches and the width is also 2h inches.
The total surface area of the rectangular prism is given by the formula:
Surface Area = 2lw + 2lh + 2wh
Substituting the values, we have:
576 = 2(2h)(2h) + 2(2h)(h) + 2(2h)(h)
576 = 8h² + 4h² + 4h²
576 = 16h² + 4h²
576 = 20²
h² = 576/20
h² = 28.8
h = √28.8
h = 5.37
The height of the prism is approximately 5.37 inches.
The length and width will be twice the height, so the length is approximately 2 * 5.37 = 10.74 inches, and the width is also approximately 2 * 5.37 = 10.74 inches.
