Answer:
(34, 48)
Step-by-step explanation:
According to the Empirical Rule, 95% of normally distributed data lie within two standard deviations of the mean. That, in turn, means 95% of the data in this problem lie within 2(3.5 min), or 7 min, of the mean:
41 - 7 < mean < 41 + 7, or
34 < mean < 48, or simply (34, 48)

Bobby and Marie are running a lemonade stand.They spend $12 on all their materials and charge $1.50 for each cup of lemonade. If they sell 20 cups of lemonade, how much money would they make(or lose)?
Answer:
$18
Step-by-step explanation:
First you would multiply $1.50 by how many cups of lemonade they sell (20). Your answer for this would be $30. After that you want to subtract the $12 from the $30, because they spent $12 on materials. Then you get $18, which is your answer. Hope this helps :)

Ms. Benson can pay $293.22 for her gym membership upfront, or she can pay the amount over a period of six months. How much would Ms. Benson pay each month for the sixth month period?
Answer:
She would have to pay $48.87 a month for six months.
Step-by-step explanation:
293.22 ÷ 6 = 48.87
Answer:
$48.87
Step-by-step explanation:
For example, if it was a backruptcy we would need to get the principal amount using the simple interest formula.
Interest = Principal * interest rate * term
180 = P * 2% * 1
180 / 2% = P
9,000 = Principal
Benson pays an additional interest of 9,000 each year. Monthly payment of 750.
9,000 / 12 months = 750 per month.
But since we are just dividing the answer will be 293.22 ÷ 6 = 48.87

The dot plot shows two students’ scores on 12 history quizzes.
Which of the following statements correctly compares the median and the range of their scores?
A. The median of Lolo’s scores is greater that the median of Ami’s scores, and the range of Ami’s scores is greater that the range of Lolo’s scores
B. The medians are equal, and the range of Ami’s scores is greater than the range of Lolo’s scores
C. The medians are equal, and the range of Lolo’s scores is greater than the range of Ami’s scores
D. The median and range of Lolo’s scores are greater than the median and range of Ami’s scores
Answer:
The correct answer is B
Step-by-step explanation:
Both of their medians are equal and Ami's range is larger than Lolo's range :)
The medians are equal, and the range of Ami’s scores is greater than the range of Lolo’s scores
Option B is the correct answer.
What is median?It is the middle value of the given set of numbers after arranging the given set of numbers in order.
We have,
Lolo's quiz:
Scores: 12, 13, 13, 14, 14, 14, 15, 16, 16, 17, 17, 19
Median.
= (14 + 15)/2
= 14.5
Range,
= 19 - 12
= 7
Ami's score:
Scores: 10, 12, 12, 13, 13, 14, 15, 16, 17, 17, 18, 18
Median.
= (14 + 15)/2
= 14.5
Range.
= 18 - 10
= 8
We can say that,
The median is the same for both and Ami's range is greater than Lolo's.
Thus,
The medians are equal, and the range of Ami’s scores is greater than the range of Lolo’s scores

Find the perimeter of quadrilateral ABCD with vertices A=(1,1) B=(4,4) C=(7,1) D=(4,-2). Explain your answer.
we have the coordinates of ABCD
there are 2 ways of doing this one is you find the distance of ab, bc, cd and da and then add the answers together. there is another way but i dont remember it properly so i am just gonna do it this way
distance between 2 point = [tex]\sqrt{(x_B-x_A)^2+(y_B-y_A)^2}[/tex]
AB
[tex]d = \sqrt {(4 - 1)^2 + (4 - 1)^2}[/tex]
[tex]d = \sqrt {(3)^2 + (3)^2}[/tex]
[tex]d = \sqrt {9 + 9}[/tex]
[tex]d = \sqrt 18[/tex]
AB = 4.24
now repeat the same with all
BC= 4.24
CD= 4.24
DA= 4.24
so its a square with all the same sides so perimeter is 4 x 4.24
perimeter is 16.96

Smaller circle C is inside larger circle C. The smaller circle is labeled the garden. The radius of the smaller circle is 8 feet. The distance from the rim of the inner circle to the rim of the outer circle is 3 feet. A circular garden with a radius of 8 feet is surrounded by a circular path with a width of 3 feet. What is the approximate area of the path alone? Use 3.14 for Pi. 172.70 ft2 178.98 ft2 200.96 ft2 379.94 ft2
Answer:
178.98 ft2
Step-by-step explanation:
The approximate area of the path is 179 ft².
Area of the smaller circleThe area of the smaller circle is calculated as follows;
A₁ = πr₁²
Where;
r₁ is the radius of the smaller circle = 8 ftA₁ = π x 8²
A₁ = 201.088 ft²
Area of the bigger circleA = πr₂²
Where;
r₂ is the radius of the bigger circle = 8 + 3 = 11 ftA₂ = π x (11)²
A₂ = 380.18 ft²
Area of the pathA = A₂ - A₁
A = 380.182 ft² - 201.088 ft²
A = 179.094 ft²
Thus, the approximate area of the path is 179 ft².

Explanation:
To get the LCM (lowest common multiple) of 8 and 10, we can multiply the two values together to get 8*10 = 80, then we divide by the GCF (greatest common factor) which is 2 to get to the LCM of 80/2 = 40.
While 80 is a common multiple of 8 and 10, it is not the smallest such value. That would be 40. So that's why we divided by 2.
Another route we can take is to list out the multiples of 8 and 10 like so
multiples of 8 = {8, 16, 24, 32, 40, 48, 56, 64, 72, 80, ...}multiples of 10 = {10, 20, 30, 40, 50, 60, 70, 80, ...}as shown in bold above, the value 40 is in both lists and it is the smallest such common item.
So this tells us that the last two digits are 4 and 0 in that order.
--------------
The GCF of 30 and 75 is 15 since we can say
30 = 15*2
75 = 15*5
Note how the 2 and 5 have no other factors in common, other than 1. This helps us see how 15 is the largest shared factor. So the first two digits are 1 and 5 in that order.
Overall, the four digit code is 1540.
