Answer:
$8,287,429
Step-by-step explanation:
The total profit will be the sum of a geometric series. The formula for that sum is ...
Sn = a1 × (r^n -1)/(r -1)
where a1 is the first term, r is the common ratio, and n is the number of terms.
__
Here, the series has first term $140,000, common ratio 1+0.20 = 1.2, and we want the total of 14 terms. The total profit is ...
S14 = ($140,000) × (1.2^14 -1)/(1.2 -1) ≈ $8,287,429
In the first 14 years of operation, the total profit would be $8,287,429.

Increase in price:
Price of next model:
Answer:
increase in price = $6664
price of next model = $56664
Step-by-step explanation:
(11.9 ÷ 100 ) x 56000 = $6664
56000 + 6664 = $56664
find the value of each of the lettered angles in the diagram below
Answer:
Step-by-step explanation:
Remark
You have an isosceles triangle. That means that the angles opposite the marked sides are equal. So mark the angle on the lower left of the triangle as 50 degrees.
The solution to problem depends on the fact that the sum of the two inside angles of the triangle (each of which is marked as 50 degrees) not supplementary to the exterior angle, are still equal to the exterior angle.
Givens
<1 = 50 degrees
<2 = 50 degrees
Exterior angle = 15x + 25 Substitute the givens into the equation
Equation
<1 + <2 = 15x + 25
Solution
50 + 50 = 15x + 25 Combine the left side
100 = 15x + 25 Subtract 25 from both sides
100 - 25 = 15x + 25 - 25 Combine
75 = 15x Divide both sides by 15
75/15 = 15x/15
5 = x
Answer
<1 = 50 degrees
<2 = 50 degrees
15x + 25 = 75 + 25 = 100

The line passes through points A (6:0) and B(O:4). Write the equation of the line.
Answer:
y = (-2/3)x + 4 or
3y = -2x + 12
Step-by-step explanation:
Slope of line passing through (x₁, y₁) and (x₂, y₂) is given by
[tex]\frac{y_{2} - y_{1}}{x_{2} - x_{1}}[/tex]
In this particular case where the points are (6,0) and (0,4) we get the slope as (4-0)/(0-6) = -2/3
Equation of a line with slope m and y intercept c is given by
y = mx + c
substituting for m we get the equation y = (-2/3)x + c
Substituting the first point (6,0) we get
0 = (-2/3)(6) + c or -4 + c = 0 or c =4
Therefore y = (-2/3)x + 4 or multiplying both sides by 3 we get
3y = -2x + 12

Step-by-step explanation:
If 5x - 8 = 12 , then x = 4
5x - 8 = 12
5x = 12 + 8
5x = 20
x = 20/5
x = 4
If -2(3x + 5) = -17 + x , then x = 1
-2(3x + 5) = -17 + x
-6x - 10 = -17 + x
x + 6x = 17 - 10
7x = 7
x = 7/7
x = 1

A) 30x
B) 30
C) 11.3
D) 11
Answer:
A) 30x
Step-by-step explanation:
5(x - 2x + 6x + 10)
Distribute:
5(x) + 5(-2x) + 5(6x) + 5(10)
5x - 10x + 30x + 50
Therefore, 5(x - 2x + 6x + 10) is equivalent to 5x - 10x + 30x + 50
Hope this helps!
Answer:
A) 30x
Step-by-step explanation:
Given equation:
5(x – 2x + 6x + 10) = 5x – 10x + ? + 50
Let the "?" be represented as "a". Then,
⇒ 5(x – 2x + 6x + 10) = 5x – 10x + a + 50
[Right hand side] Put all the terms inside a parenthesis (except "a").
⇒ 5(x – 2x + 6x + 10) = 5x – 10x + a + 50
⇒ 5(x – 2x + 6x + 10) = (5x – 10x + 50) + a
Isolate the "a" on one side by subtracting the terms inside the parenthesis.
⇒ 5(x – 2x + 6x + 10) - (5x – 10x + 50) = (5x – 10x + 50) + a - (5x – 10x + 50)
⇒ 5(x – 2x + 6x + 10) - 5x + 10x - 50 = a
[Left hand side] Simplify the distributive property
⇒ 5(x – 2x + 6x + 10) - 5x + 10x - 50 = a
⇒ (5x – 10x + 30x + 50) - 5x + 10x - 50 = a
[Left hand side] Open the parentheses
⇒ (5x – 10x + 30x + 50) - 5x + 10x - 50 = a
⇒ 5x – 10x + 30x + 50 - 5x + 10x - 50 = a
[Left hand side] Combine like terms and simplify
⇒ 5x – 10x + 30x + 50 - 5x + 10x - 50 = a
⇒ x(5 – 10 + 30 - 5 + 10) + (50 - 50) = a
⇒ x(30) = a
[Left hand side] Open the parenthesis and simplify
⇒ x(30) = a
⇒ 30x = a = ?
Therefore, the correct option is A (30x).

A teacher administers three different versions of a test to his students The two-way table shows the results.
Find the probability of the event below using the formula for conditional probability. Round your answer to the nearest tenth.
P(pass | Test A)
The probability is ____%
SHOW ALL WORK
The P(pass | Test A) is 31.81%, P(pass | Test B) is 29.87%
What is probability?It is defined as the ratio of the number of favourable outcomes to the total number of outcomes, in other words, the probability is the number that shows the happening of the event.
Part A:
Total number of students = 154
Total number of students passed the test = 49
The probability:
P(pass | Test A) = 49/154 = 31.81%
Part B:
Total number of students = 154
Total number of students passed the test = 46
The probability:
P(pass | Test B) = 46/154 = 29.87%
Thus, the P(pass | Test A) is 31.81%, P(pass | Test B) is 29.87%.

Aiden earned a score of 22 on exam a that had a mean of 40 and a standard
deviation of 10. he is about to take exam b that has a mean of 650 and a standard
deviation of 25. how well must aiden score on exam b in order to do equivalently
well as he did on exam a? assume that scores on each exam are normally distributed.
Using the normal distribution, it is found that he needs a score of 605 in exam b in order to do equivalently well as he did on exam a.
Normal Probability DistributionThe z-score of a measure X of a normally distributed variable with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex] is given by:
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
The z-score measures how many standard deviations the measure is above or below the mean. Looking at the z-score table, the p-value associated with this z-score is found, which is the percentile of X.For the z-score for exam a, we have that the parameters are given as follows:
[tex]X = 22, \mu = 40, \sigma = 10[/tex]
Hence:
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
[tex]Z = \frac{22 - 40}{10}[/tex]
Z = -1.8.
Then, for the equivalent grade X in exam B, we have that:
[tex]Z = -1.8, \mu = 650, \sigma = 25[/tex]
Then:
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
[tex]-1.8 = \frac{X - 650}{25}[/tex]
X - 650 = -1.8 x 25
X = 605.
