SP and Enrich are water pump manufacturers. SP claims that its water pumps have a higher maximum discharge flow rate than Enrich water pumps with the same specifications. To test the claim, a consumer bureau selected 10 water pumps from each manufacturer by visiting the distribution sites of both SP and Enrich and blindly selecting one water pump from 10 different lots at their sites. The consumer bureau found that, on average, SP water pumps had a 4% higher maximum discharge flow rate than Enrich water pumps. Given the bureau’s data collection method and report, what conclusion can be made?
A. The collection method was unfair because SP's claim may have influenced the bureau's report.
B. The collection method was random because the selection process ensured a random representation of each manufacturer's water pumps.
C. The collection method was fair because SP water pumps had the higher maximum discharge flow rate.
D. the collection method was nonrandom because only 10 water pumps from each manufacturer were selected.
Answer:
The collection method was random because the selection process ensured a random representation of each manufacturer’s water pumps.
Step-by-step explanation:
Given the Bureau’s data collection method and report, the conclusion that can be made is "The collection method was random because the selection process ensured a random representation of each manufacturer's water pumps.". Option B. This is further explained below.
What is data collection?Generally, data collection is simply defined as the process of acquiring and measuring information on variables of interest in a systematic manner
In conclusion, with the Bureau's data collecting technique and report, one might draw the following conclusion; The collection method was random since the selection procedure assured a random representation of each manufacturer's water pumps.

On Monday, Courtney spent 14 minutes solving 1 math problem and 2 biology problems. On Tuesday, Courtney spent 16 minutes solving 2 math problems and 1 biology problem. Write and solve a system of equations to find how long it takes Courtney to solve each math problem and each biology problem
Answer:
the timing taken to solve each math problem and each biology problem is 4 minutes each respectively
Step-by-step explanation:
Let us assume the timing taken for math problem be x
And, the time taken for biology problem be y
Now as per the question
The following equations should be considered
x + 2y = 14 .............(1)
2x + y = 16. ...................(2)
Multiply by 2 in equation 1
So,
2x + 4y = 28
2x + y = 16
3y = 12
y = 4 minutes
So, x = 14 - 2(4)
= 12 - 8
= 4 minutes
hence, the timing taken to solve each math problem and each biology problem is 4 minutes each respectively
Find the slope of the line
Answer:
2 or 2/1
Step-by-step explanation:
First we put -"3y" to the other side of the equation to get
3y=6x+6
Now divide everything by 3 to get "y" by itself.
y=2x+2
The slope is 2 or 2/1
Answer:
b.2
Step-by-step explanation:
6x-3y+6=0
-3y=-6x-6 divide both sides by -3
y=2x+2

The following function represents the value of a truck, in dollars, after x years:
f(x) = 29,000(0.88)x
What does 0.88 represent?
The decrease in the value of the truck, which is 12%
The present value of the truck
The value of the truck after x years
The decrease in the value of the truck, which is 88%
Answer:
The increase in the value of the truck, which is 88%
Step-by-step explanation:
Depreciation can be defined as the reduction of cost of a fixed asset systematically until the value of the asset becomes zero.
Rate of return can be defined as the percentage of interest or dividends earned on money that is invested.
In Financial accounting, a return refers to the amount of profit generated by an investor on an investment over a specific period of time.
Basically, the rate of return which is typically expressed as a percentage of the initial costs of an investment can either be a gain or a loss on an investment. Therefore, a positive rate of return on an investment over a specific period of time, simply means that an investor is making a profit (gains) while a negative rate of return on an investment over a specific period of time, indicates that the investor is running at a loss.
Given the following function;
f(x) = 29,000(0.88)x
Where;
x is the number of years.
We can deduce from the function, that the rate at which the truck is appreciating is 88% (0.88).
Assuming x = 3
f(3) = 29,000(0.88)*3
f(3) = $76,560
Answer:
The decrease in the value of the truck, which is 12%
Step-by-step explanation:
If the decrease in the value of the truck was 88%, then the percentage would be 0.12. So therefore, since 1.00 - 0.12 is 0.88, the decrease in the value of the truck would be 12%.

so if he get $8 per day + 6 per walk {w}
so 8 + 6w = 14 change the + into - and change the 8 into -8 and
put it on both side 14 - 8 is 6
then you have to put 6w = 6 then

You want to rent a television. Company A charges $25 per week plus a one-time fee of $52. Company B charges $37 per week plus a one-time fee of $16. After how many weeks are the total costs the same at both companies?
Answer:
3 weeks
Step-by-step explanation:
Set the number of weeks when they are equal as x.
We can then write these equations.
25x + 52 = 37x + 16
Subtract 25x from both sides.
52 = 12x + 16
Subtract 16 from both sides.
36 = 12x
Divide both sides by 12
x = 3
The answer is 3 weeks.
Solve the equation for x:
Answer:
A. x = 10
Step-by-step explanation:
-5x + 20 = -30
Subtract 20 from both sides
-5x = -50
Divide both sides by -5
x = 10
Answer:
A. x = 10
Step-by-step explanation:
- 5x + 20 = - 30
- 5x = - 30 - 20
- 5x = - 50
5x = 50
x = 50 / 5
x = 10

We have:
[tex]\displaystyle \cos\theta\cdot \cot\theta+\sin^2\theta\cdot \csc\theta=\csc\theta[/tex]
Rewrite:
[tex]\displaystyle \cos\theta\left(\frac{\cos\theta}{\sin\theta}\right)+\sin^2\theta\left(\frac{1}{\sin\theta}}\right)=\csc\theta[/tex]
Multiply:
[tex]\displaystyle \frac{\cos^2\theta}{\sin\theta}+\frac{\sin^2\theta}{\sin\theta}=\csc\theta[/tex]
Combine:
[tex]\displaystyle \frac{\cos^2\theta+\sin^2\theta}{\sin\theta}=\csc\theta[/tex]
According to the Pythagorean Identity, sin²θ + cos²θ = 1. Hence:
[tex]\displaystyle \frac{1}{\sin\theta}=\csc\theta[/tex]
Simplify:
[tex]\csc\theta=\csc\theta[/tex]
12)
We have:
[tex]\displaystyle \frac{\cos^2\theta +\sin^2\theta}{1+\tan^2\theta}=\cos^2\theta[/tex]
Pythagorean Identity:
[tex]\displaystyle \frac{1}{1+\tan^2\theta}=\cos^2\theta[/tex]
From the Pythagorean Identity, if we divide both sides by cos²θ, we acquire that tan²θ + 1 = sec²θ. Hence:
[tex]\displaystyle \frac{1}{\sec^2\theta}=\cos^2\theta[/tex]
Simplify:
[tex]\cos^2\theta =\cos^2\theta[/tex]
13)
We have:
[tex]\displaystyle \frac{\csc\theta\cdot \cos\theta}{\tan\theta +\cot\theta}=\cos^2\theta[/tex]
Rewrite:
[tex]\displaystyle \frac{1/\sin\theta\cdot \cos\theta}{\sin\theta/\cos\theta+\cos\theta/\sin\theta}=\cos^2\theta[/tex]
Multiply both top and bottom by cosθsinθ. Hence:
[tex]\displaystyle \frac{\cos^2\theta}{\sin^2\theta +\cos^2\theta}=\cos^2\theta[/tex]
By the Pythagorean Identity:
[tex]\displaystyle \frac{\cos^2\theta}{1}=\cos^2\theta[/tex]
Simplify:

Choose is 12,194,65,10
Answer:
x = 12
Step-by-step explanation:
By applying Pythagoras theorem in the given right triangle,
(Hypotenuse)² = (leg 1)² + (leg 2)²
From the picture attached,
Length of Hypotenuse = 13
Length of leg 1 = 5
Length of leg 2 = x
By substituting these values in the formula,
(13)² = 5² + x²
169 = 25 + x²
169 - 25 = x²
144 = x²
(12)² = x²
x = 12

Find the missing angles in the following triangles.
Answer:
Step-by-step explanation:
angles in triangle = 180
1. 180 - (70+45) = x = 65
2. x = 35
180 - 110 = 70
70/2 = 35 (isosceles triangle)
3. x = 113, y = 67
180 - (62 + 51) = y = 67
Angles on a line = 180
180 - 67 = x = 113
4. x = 60, y = 50
x = 180 - 120 = 60
y = 180 - (60 + 70) = 50
