Use the box plot to determine which statement is accurate.
A) About 25% of adults have cholesterol levels of at most 212.
B) About 75% of adults have cholesterol levels less than 180.
C) One half of the cholesterol levels are between 180 and 197.5
D) One half of the cholesterol levels are between 180 and 211.
Answers
The accurate statements are:
A) About 25% of adults have cholesterol levels of at most 212.
D) One half of the cholesterol levels are between 180 and 211.
Q₃ (the third quartile) is 211, which is less than 212,
About 25% of adults have cholesterol levels of at most 212 is accurate.
Q₁ (the first quartile) is 100, which is greater than 180, About 75% of adults have cholesterol levels less than 180 is not accurate. We cannot determine that about 75% of adults have cholesterol levels less than 180 based on the given information.
The median divides the data into two equal halves, and it falls between Q₁ and Q₃.
So, one half of the cholesterol levels are between Q₁ and the median, but not specifically between 180 and 197.5.
One half of the cholesterol levels are between 180 and 211, as Q₁ is the lower boundary and Q₃ is the upper boundary of the interquartile range.

Find the perimeter of the parallelogram with these vertices.
(6,4),(-1, 4), (1, -5), (-6, -5)
Answers
Answer:
34.6
Step-by-step explanation:
The perimeter of a plane geometric figure is the sum of its side lengths. This figure has two horizontal sides, so their length is easy to compute. It also has two diagonal sides, so the distance formula or Pythagorean theorem must be invoked to find their length.
The length of diagonal AC is ...
d = √((x2 -x1)² +(y2 -y1)²)
d = √((1 -6)² +(-5 -4)²) = √((-5)² +(-9)²) = √106 ≈ 10.3
The length of each horizontal segment can be found by counting grid squares or by finding the difference of x-coordinates.
AB = 6 -(-1) = 6 +1 = 7
__
Two sides have length 10.3 and two sides have length 7, so the perimeter is ...
P = 2(10.3 +7) = 34.6 . . . units

Elena works at an appliance store. She recorded her recent sales.

Of the next 12 appliances Elena sells, how many should she expect to be ovens, given the past data?
Answers
Using proportions, it is found that she should expect 4 of the next 12 appliances to be ovens.
What is a proportion?A proportion is a fraction of a total amount, and the measures are related using a rule of three.
In this problem, we have that out of 15 items, 5 are ovens. How many will be out of 12? To find out, we start with the rule of three.
15 items - 5 ovens
12 items - x ovens
Applying cross multiplication:
15x = 60
x = 4.
Hence, 4 of the next 12 appliances to be ovens.

A newspaper advertisement offers a $6500 used car for nothing down and 36 easy monthly payments of

Simple Interest Rate:

Answers
Using simple interest, it is found that:
The total amount paid was of $7,084.8.The finance charge was of $584.8.The simple interest rate was of 3%.Simple InterestSimple interest is used when there is a single compounding per time period.
The amount of interest after t years in is modeled by:
[tex]I = Prt[/tex]
In which:
P is the initial amount.r is the interest rate, as a decimal.In this problem, the amount paid was of 36 monthly payments of
$196.80, hence:
36 x 196.80 = $7084.8.
The total amount paid was of $7,084.8.
The original price is of $6,500, hence the finance charge was of:
7084.8 - 6500 = $584.8.
For interest, we have that:
[tex]I = 584.8, P = 6500, t = 3[/tex], hence:
[tex]I = Prt[/tex]
[tex]584.8 = 6500(3)r[/tex]
[tex]r = \frac{584.8}{6500 \times 3}[/tex]

A survey in September 2020 of 1000 gas stations found that the price charged for a gallon of regular gas could be closely approximated by a normal distribution with a mean of $3.53 and a standard deviation of $0.20.
Draw the normal distribution with these numbers.
a. How many stations charge over $3.93?
b. How many of the stations charge between $3.13 and $3.93 for a gallon?
c. How many stations charge less than $3.33?
Answers
Ex 1 SD is 3.73, 2SD is 3.93, -1SD is 3.33
Now to solve the questions
A. If we know there’s 1000 gas stations and 3.93 is just 2 SD we can just refer to the picture below.
Basically because we’re finding the amount of values that are greater than that it should be percentage to the right of 2 SD. Which is 2.2% or 0.022 Then multiply that by the number of gas station.
So 0.022 * 1000 = 22.
B. This is basically the values between -2SD and 2 SD which is the percentage between them. Add 13.6 *2 + 34.1*2 = 95.2% or 0.952
Now multiply by 1000 * 0.952=952 gas stations.
C. For this one we just find percentage to the left of -1 SD or simpler just subtract half(the right half) and the percentage in 1 SD from 1 to find the remainder which is the value left of -1SD.
1-0.5 - 0.341 = 0.159
Now multiply by 1000 * 0.159 = 159 stations.
Hopefully this helps.

Find the value of each variable in the parallelogram. Please help!
Answers
Answer:
m = 35 , n = 110
Step-by-step explanation:
the opposite angles of a parallelogram are congruent , then
2m = 70 ( divide both sides by 2 )
m = 35
consecutive angles are supplementary, that is sum to 180° , then
n + 70 = 180 ( subtract 70 from both sides )
n = 110
Solution:
We know that:
In a parallelogram, opposite angles are equivalentThis means that:
70 = 2mDivide 2 both sides to find m:
70 = 2m70/2 = 2m/2m = 70/2 = 35°We can see that two angles measuring 70° and n° are a linear pair.
n + 70 = 180n = 180 - 70 = 110°How to find the area and circumference
