Answer:
4 questions
Step-by-step explanation:
To find a percentage of a number, you move the decimal mark all the way to the left.
87.5% becomes 0.875
Next you multiply 32 by 0.875 to find the percentage of questions that are completed
32 x 0.875 = 28
28 out of 32 questions have been solved, so now you subtract 28 from 32
32 - 28= 4
There are 4 questions to complete
Solve the rational equation 4 divided by x equals quantity 3 times x plus 2 end quantity divided by x squared, and check for extraneous solutions.
Answer:
x = 2
Step-by-step explanation:
Step 1: Write equation
[tex]\frac{4}{x}=\frac{3x+2}{x^2}[/tex]
Step 2: Solve for x
Cross multiply: [tex]4x^2=x(3x+2)[/tex]Distribute x: [tex]4x^2=3x^2+2x[/tex]Subtract 3x² on both sides: [tex]x^2=2x[/tex]Subtract 2x on both sides: [tex]x^2-2x=0[/tex]Factor: [tex]x(x-2)=0[/tex]Solve: [tex]x = 0, 2[/tex]Step 3: Check
Plug in x to verify it's a solution.
Substitute: [tex]\frac{4}{0}=\frac{3(0)+2}{0^2}[/tex]Evaluate: undef (cannot divide by 0)Substitute: [tex]\frac{4}{2}=\frac{3(2)+2}{2^2}[/tex]Evaluate: [tex]2=\frac{6+2}{4}[/tex]Evaluate: [tex]2=\frac{8}{4}[/tex]Evaluate: [tex]2=2[/tex]Distribute the following 3(2x+6)
Answer:
6x+18
Step-by-step explanation:
3(2x+6)

Jane wants to buy carpet for her room measuring 400 square feet. She purchased carpet that costs $20 per square yard. How much will it cost to have her room carpeted? (1 square yard = 9 square feet) Explain how you solved it.
Answer:
About $888.88
Step-by-step explanation:
divide 400 by 9 to get the total number of how much square yards she needs
400/9 = 44.44444444
Multiply 44.44444444 with $20 to get the amount which is about 888.88
Find values of a and b that make both equalities true: a/b = 2/5 and 22/a = 11/6 .
Answer:
a=32b=80Step-by-step explanation:
Find values of a and b that make both equalities true:
a/b = 2/5 and 22/a = 11/6 .
given that 22/a=11/16
cross multiply
11a=22x16
11a=352
a=352/11
a=32
put a=32 in a/b = 2/5 to find b we have
32/b=2/5
cross multiply we have
2b=32x5
2b=160
divide both sides by 2 we have
b=160/2
b=80
Answer:
Step-by-step explanation:
First, we will start by solving: 22/a = 11/6
Solving for a
We can first cross multiply and we get this: 22 x 6 = 11a, Simplified it would be 132 = 11a. Now we know that a = 12.
Solving for b
Now knowing a = 12 we can get this. 12/b = 2/5 same thing, cross multiply. That would be: 12 x 5 = b x 2, Simplified: 60 = 2b so b = 30

Answer:
5 hours; Home Decor
Step-by-step explanation:
First thing you want to do is make an equation of the two to find when they'll be the same price. So it'll look something like this:
500+35x=600+15x
Get like terms together
100=20x
divide
x=5
After 5 hours, they'll be the same price.
For the second half, plug in the number 3 instead of 5 into the original equation
500+105 600+45
605 645
So he'd go with the first company

Question 16
which statement BEST describes the relationship between Georgia and Great Britain during the colonial period?
A Farm machinery was shipped from Georgin, manufactured goods were shipped from Britain, and neither side controlled what was produced
Manufactured goods were shipped from Georgia, raw materials were shipped from Britain, and Georgia controlled which raw materials were produced
Food crops were shipped from Georgia, manufactured goods were shipped from Britain, and Georgia controlled which manufactured goods were produced
D
Raw materials were shipped from Georgia, manufactured goods were shipped from Britain, and Britain controlted which raw materials wore produced
Answer: D . Raw materials were shipped from Georgia, manufactured goods were shipped from Britain, and Britain controlled which raw materials wore produced
Step-by-step explanation:
In the colonial era of the United States, the British who were in charge then engaged in an Economic policy called Mercantilism. This was a system where they limited imports into Britain but encouraged exports from Britain so that they would maintain a favorable balance of trade.
A key part of this system was having colonies that goods could be exported to and that raw materials could be acquired from at a cheap rate.
Southern colonies like Georgia fulfilled this mandate more than the rest as they would ship raw materials to Britain and buy manufactured goods from them with Britain controlling which raw materials Georgians produced.

Suppose a manufacturer finds that 95% of their production is normal but the final 5% has one or more flaws. Each flawed good has a financial cost to the firm of $1. The manufacturer tasks a team led by you, the manager to identify the likelihood of upcoming flaws by providing your best expectation. Here is what you found by reviewing past production.Of the flawed goods:80% show Type 1 flaws.50% show Type 2 flaws.30% show both Type 1 and Type 2 flaws.1. Make a Bivariate Table using the above data.2. What is the probability and expectations of type 1 flaw?3. What is the probability and expectation of Type 2 flaw?4. What is the probability and expectations of Type 1 and 2 flaws?5. What is the probability and expectations of no flaws?
Answer:
1)
FLAW TYPE2 NO TYPE2 FLAW
TYPE1 0.015 0.025
NO TYPE1 FLAW 0.01 0.95
2) 0.04 and $0.04
3) 0.025 and $0.025
4) 0.015 and $0.015
5) 0.95 and $0.95
Step-by-step explanation:
Given that;
financial cost = $1
p(flaw) = 0.05
p(type 1 flaw / flaw) = 80% = 0.8
p(type 2 flaw / flaw) = 50% = 0.5
p( type 1 and 2 flaw/flaw) = 30% = 0.30
1) Bivariate Table
p( type 1 flaw) = p(flaw) × p(type 1 flaw/flaw) = 0.05 × 0.8 = 0.04
p( type 2 flaw) = p(flaw) × p(type 2 flaw/flaw) = 0.05 × 0.5 = 0.025
p( type 1 and 2 flaw) = p(flow) × p( type 1 & 2 flaw/flaw) = 0.05 × 0.3 = 0.015
p( only 1 flow) = 0.04 - 0.015 = 0.025
p( only 2 flow) = 0.025 - 0.015 = 0.01
THEREFORE the Bivariate Table;
FLAW TYPE2 NO TYPE2 FLAW
TYPE1 0.015 0.025
NO TYPE1 FLAW 0.01 0.95
2) probability and expectations of type 1 flaw?
p( type 1 flaw) = p(flaw) × p(type 1 flaw/flaw) = 0.05 × 0.8 = 0.04
Expected financial cost to the firm per good = $1 × 0.04 = $0.04
3) probability and expectation of Type 2 flaw
p( type 2 flaw) = p(flaw) × p(type 2 flaw/flaw) = 0.05 × 0.5 = 0.025
Expected financial cost to the firm per good = $1 × 0.025 = $0.025
4) probability and expectations of Type 1 and 2 flaws
p( type 1 and 2 flaw) = p(flow) × p( type 1 & 2 flaw/flaw) = 0.05 × 0.3 = 0.015
Expected financial cost to the firm per good = $1 * 0.015 = $0.015
5) probability and expectations of no flaws?
Probability of no flaw = P(No flaw) =95% = 0.95
Expected financial cost saved the firm per good due to no flaw
= $1 × 0.95 = $0.95

The partial blueprint for an office building shows one outer wall and a perpendicular inner wall. Which of the following could be the equation of the inner wall, if the outer wall is represented by the equation y = 2/5x-1
a. y= -5/2x -4
b. y= -2/5x-4
c. y=5/2x-4
d. y=2/5x-4
Answer:
a. y= -5/2x -4
Step-by-step explanation:
An equation that is perpendicular to another equation must have the opposite slope. In other words, the perpendicular equation will be the opposite sign & the reciprocal of the equation it is perpendicular to. In this case, the perpendicular slope is -5/2x. Therefore, the only answer possible is a.

Step-by-step explanation:
Matek spends 4/5 of his homework time on math. He spends 1/12 of it on writing. What fraction of his homework time is spent on math or writing? Simplify the answer if possible.
Answer:
53/60 of his homework time
Step-by-step explanation:
We need to find 1/12 of 4/5, which can be calculated via the addition:
1/12 plus 4/5
1/12 + 4/5 = 5/60 + 48/60 = 53/60
So Matek spent 53/60 of his homework time on writing or math
The standard deviation from the National Health and Nutrition Survey is 1.29 hours. What is the variance (rounded to the hundredth place) ?
Answer:
variance = 1.66 hours
Step-by-step explanation:
It is given that,
The standard deviation from the National Health and Nutrition Survey is 1.29 hours.
We need to find the variance. We know that the relationship between the variance and the standard deviation is given by :
[tex]\text{Variance }=\text{standard deviation}^2\\\\\text{Putting all the values, we get :}\\\\\text{Variance }=(1.29)^2\\\\\text{Variance }=1.664\ \text{hours}[/tex]
or
Variance = 1.66
So, the variance is 1.66 hours.
