What is the interquartile range of the following data set?
45, 12, 48, 96, 61, 84, 29, 1,72,5,14
a.45
b.33
c.27
d.60
(apex)
Answer:
The interquartile range is 60 ⇒ D
Step-by-step explanation:
The interquartile range is the difference between the upper quartile and the lower quartile
Let us explain how to find the interquartile range
Arrange the number from smallest to greatestFind its median Q1 (the middle number in the set of numbers)Find the lower quartile Q1 which is the median of the set of the numbers before the median Find the upper quartile Q3 which is the median of the set of the numbers after the median Subtract Q1 from Q3 the answer is the interquartile rangeLet us do these steps to find it
∵ The data set is {45, 12, 48, 96, 61, 84, 29, 1, 72, 5, 14}
→ Arrange them
∴ The data set is {1, 5, 12, 14, 29, 45, 48, 61, 72, 84, 96}
∵ They are 11 numbers
∴ The middle number is the 6th number (5 before it and 5 after it)
∵ The 6th number is 45
∴ The median is 45
→ Find the lower set (before the median)
∴ The lower set is {1, 5, 12, 14, 29}
→ Find the lower quartile Q1
∵ The lower quartile is the middle number in this set
∵ There are 5 numbers
∴ The middle one is the 3rd
∵ The 3rd is 12
∴ Q1 = 12
→ Find the upper set (after the median)
∴ The upper set is {48, 61, 72, 84, 96}
→ Find the upper quartile Q3
∵ The upper quartile is the middle number in this set
∵ There are 5 numbers
∴ The middle one is the 3rd
∵ The 3rd is 72
∴ Q3 = 72
→ Subtract them to find the interquartile range
∵ The interquartile range = Q3 - Q1
∴ The interquartile range = 72 - 12
∴ The interquartile range = 60

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]Which situation involves an annuity?

45 degrees+2k+k=180
can you help me with this?
Answer:
k=45
Step-by-step explanation:
45+2k+k=180
Step 1: Simplify both sides of the equation.
45+2k+k=180
(2k+k)+(45)=180(Combine Like Terms)
3k+45=180
3k+45=180
Step 2: Subtract 45 from both sides.
3k+45−45=180−45
3k=135
Step 3: Divide both sides by 3.
3k/3=135/3
k=45

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

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.
Do these numbers show a proportion? Help me!
93, 15
62, 10
Answer: Yes
These numbers are a proportion. Let me show an example:
Jenna reads 93 pages of a book in 15 pages. How many pages does she read in 10 minutes?
93 ÷ 15 = 6.2
6.2 x 10 = 62
Answer: She reads 62 pages in 10 minutes.
These numbers can show a proportion like the example listed.
Hope this helps you!

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

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
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.
