Answer: $5
Step-by-step explanation: The interquartile range (IQR) refers to the difference between the upper(75%) quartile and lower(25%) quartile of a distribution. Hence, ensuring that the middle 50% is being captured. With the average given as $60, having a interquartile range capturing the middle 50% as $1 seems so small from a statistical stand point. Similarly, an interquartile range of $100 capturing the middle 50% is also too large and nearly impossible if the average price is $60. However, a price of $5 sit well in between considering the average price of $60

Explanation:
Focus on the slanted side of the parallelogram, which is 26 units long. The opposite side to this is also 26 units long since opposite sides of any parallelogram are always congruent.
Now turn your attention to the triangle formed by that dashed line. Specifically this is a right triangle. It has a legs of x and 10, where x is the unknown height (also the height of the parallelogram). The hypotenuse of this right triangle is 26 units as mentioned in the previous paragraph.
Use the pythagorean theorem to find x
a^2+b^2 = c^2
10^2+x^2 = 26^2
100+x^2 = 676
x^2 = 676-100
x^2 = 576
x = sqrt(576)
x = 24
This is a 10,24,26 right triangle, which is based on the 5,12,13 right triangle (divide every part by 2)
-------------------
Now that we know the height of the parallelogram, the area is simply base times height
area of parallelogram = base*height = 32*24 = 768
Then we subtract off the area of the shaded gray rectangle, so we subtract off 7*16 = 112 to get 768 - 112 = 656 and this is the area of the unshaded region inside the parallelogram.
-------------------
Side note: The hypotenuse of 10*sqrt(2) you wrote down would only be correct if that dashed height line was 10 units.

i think the answer is "favorite zoo animal"
Step-by-step explanation:
because one thing that can't be an answer is "scariest zoo animal" because otter has the most vote and a lion or bear is scarier than a otter, so it can't be "scariest class pet* cause of the same reason. it can either be *favorite class pet" or "favorite zoo animal". if you see, in that on if we see the chart lion has the second highest votes and lion can't be a class pet, so it is "favorite zoo animal"

A flashlight battery manufacturer makes a model of battery whose mean shelf life is three years and four months, with a standard deviation of three months. The distribution is approximately normal. One production run of batteries in the factory was 25,000 batteries. How many of those batteries can be expected to last between three years and one month and three years and seven months?
a. 21,025 batteries
b. 8,525 batteries
c. 17,050 batteries
See the attached picture.
The answer is c. 17,050 batteries
The number of expected batteries to last between 3 years and one month and 3 years and seven months is 17,050 batteries.
Option C is the correct answer.
What is z-score?A z-score also called a standard score is a measure of how many standard deviations a data point is away from the given mean of a distribution.
It measures the unusual or extreme a particular data point is compared to the rest of the distribution
We have,
First, we need to standardize the range of shelf life between three years and one month (3.08 years) and three years and seven months (3.58 years) using the formula:
z = (x - μ) / σ
where x is the shelf life in years, μ is the mean shelf life in years, and σ is the standard deviation in years.
Now,
For the lower bound:
z = (3.08 - 3.33) / 0.25
z = -1.00
For the upper bound:
z = (3.58 - 3.33) / 0.25
z = 1.00
Now,
We use a standard normal distribution table or calculator to find the area under the curve between z = -1.00 and z = 1.00, which represents the proportion of batteries that can be expected to last between three years and one month and three years and seven months.
This area is approximately 0.6826.
Finally,
We multiply this proportion by the total number of batteries in the production run to find the expected number of batteries that meet the criteria.
expected number = proportion x total number
expected number = 0.6826 * 25,000
expected number ≈ 17,065
Therefore,
The number of expected batteries is 17,050 batteries.

Solve: log (7t + 2) = 2
t =
Answer:
t = 14
Step-by-step explanation:
log (7t + 2) = 2
Raise each side to the power of 10
10 ^log (7t + 2) =10^ 2
7t+2 = 100
Subtract 2 from each side
7t+2-2 = 100-2
7t = 98
Divide each side by 7
7t/7 = 98/7
t = 14
Answer:
[tex]t=14[/tex]
Step-by-step explanation:
We begin with the equation: [tex]log(7t+2)=2[/tex]
The first thing we must do is remove the log. In this case, the base of this log is 10, which means that we must have each side of this equation have a base of 10.
This gives us
[tex]10^{log(7t+2)} =10^2[/tex]
The base 10 and the log will cancel out to give us
[tex]7t+2=100[/tex]
Then we can solve for t
[tex]7t+2=100\\\\7t=98\\\\t=\frac{98}{7} \\\\t=14[/tex]

Amara has taken out a fixed rate mortgage for $125,000 at 4.04% for 20 years, or 240 months. Her payments are $730. What is the total cost of the loan?
A. $130,050
B. $175,200
C. $211,680
D. $226,000
Answer:
182,427.03
Step-by-step explanation:
total cost = r*p*n
---------------
1- (1+r) ^-n
Where r is the loan rate, p is the principal, n is the number of payments
rate = 4.04% / 12 months
total cost = (.0404/12)* 125000* 240

solve similar triangles
Answer:
7.5 ?
Step-by-step explanation:
Answer:
7.5
Step-by-step explanation:
We are given information that the two triangles are similar and we want to work out the length of "t" . Since these 2 triangles are similar, it means that a scale factor is used to enlarge the sides, we can work out the scale by dividing QP by LJ and RP by KJ so,
QP ÷ JK = 25 ÷ 5 = 5
RP ÷ JL = 22.5 ÷ 4.5 = 5
So we can see the scale factor is 5, now all we need to do is multiply the scale factor by 1.5 to find the value of t
1.5 × 5 = 7.5
The value of t is 7.5

The number of posters that Jason needs to sell so that the cost and revenue are equal will be 80. Option B is correct.
What is a function?A function is an assertion, concept, or principle that establishes an association between two variables. Functions may be found throughout mathematics and are essential for the development of significant links.
The amount of revenue in dollars, y, that Jason receives from selling x posters is given by the equation y = 4x. The cost of producing x posters is given by the equation y = (1/2)x + 280.
Then the number of posters that Jason needs to sell so that the cost and revenue are equal will be given as,
4x = (1/2)x + 280
4x - (1/2)x = 280
(7/2)x = 280
7x = 560
x = 80
The number of posters that Jason needs to sell so that the cost and revenue are equal will be 80.

Carly's family traveled 3/10 of the distance to her grandmother's house on Saturday. They traveled 3/7 of the remaining distance on Sunday. What fraction of the total distance to her grandmother's house was traveled on Sunday?
Answer:
3/10 of the total distance to her grandmother's house was traveled on Sunday
Step-by-step explanation:
Carly's family traveled distance of Saturday = [tex]\frac{3}{10}[/tex]
Remaining distance =[tex]1-\frac{3}{10}=\frac{7}{10}[/tex]
They traveled 3/7 of the remaining distance on Sunday.
So, Distance traveled on Sunday =[tex]\frac{3}{7}(\frac{7}{10})[/tex]
Distance traveled on Sunday =[tex]\frac{3}{10}[/tex]
