Which statement is true about this data set?
{70, 67, 66, 65, 66, 78, 68, 71, 80, 78, 72}
80 is an outlier because it is greater than the upper fence.
This data set has no outliers.
65 and 80 are both outliers because 65 is less than the lower fence and 80 is greater than the upper fence.
65 is an outlier because it is less than the lower fence.

Answer:
Option 3 - This data set has no outliers.
Step-by-step explanation:
Given : The data {70, 67, 66, 65, 66, 78, 68, 71, 80, 78, 72}
To find : Which statement is true about this data set?
Solution :
The statements is all about outlier.
So, we find the outlier of the data.
Step 1- Arranging the data from lowest to highest,
{65,66,66,67,68,70,71,72,78,78,80}
Step 2 - Find the median of the data
As the data is odd numbers so the median is th term.
term.
6th term is 70 ⇒ Median =70
Step 3 - To find Upper quartile and lower quartile
Lower quartile data set is the median of the upper terms from median
{65,66,66,67,68}
Median of the set is 66
∴
Upper quartile data set is the median of the lower terms from median
{71,72,78,78,80}
Median of the set is 78
∴
Step 4 - To find the interquartile range.
Step 5 - To find the fences for the data set.
The formula to find range is
Substitute the values, we get
The range in which data lies is [48,96]
We have seen that all the data lie inside the range.
Therefore, This data set has no outliers.
Hence, Option 3 is correct.

The length of the base of a scalene triangle is 22 meters and the height is 14 meters. Find the area of the scalene triangle
Answer:
Area is 154 square meters
Step-by-step explanation:
Well lets think about this
If I take a rectangle and cut it into half diagonally I would get 2 triangles right?
So if I have 2 triangles of the same height and base I can make a rectangle
to find the area of a rectangle I do length times width
So lets take our scalene triangle and multiply our base with its width and then divide by 2
22*14 = 308
308/2 is 154

A can is 7 inches high and has a radius of 2 inches,
r = 2 in
h = 7 in
Enter the volume, in cubic inches, of the can. Round your answer to the nearest hundreth.
Answer:
87.92 cubic inches
Step-by-step explanation:
to find the volume of a cylinder the formula is V = [tex]\pi[/tex][tex]r^{2}[/tex]h
so first i squared 2
2x2= 4
i then multiplied 4 by the height (7)
4x7 = 28
then times 28 by pi (3.14)
28x 3.14 = 87.92
The volume of cylinder is 87.92 cubic inches
volume :
volume is the amount of space in a certain 3D object.
formula used to find the volume of cylinder :
V = π × r^2 × h
as given ,
r = 2 inch
h = 7 inch
so ,
V = π × (2)^2 × 7
⇒ π × 28
V = 87.92 cubic inches
Hence , the volume of cylinder is 87.92 cubic inches .

I I need help on number 25 please
Answer:
22
Step-by-step explanation:
First write an expression to represent the situation.
$1,300,000 ≤ $475,000 + $37,500a
This expression works because the least amount of money that can make to remain profitable is 1,300,000. They already have 475,000 of that and every a (number of ads sold) is $37,500
Using this equation, solve for a.
1300000 ≤ 475000 + 37500a
First, subtract 475000 from both sides.
825000 ≤ 37500a
Then divide both sides of the equation by 37500 to isolate a.
22 ≤ a
22 is less than or equal to a. So they must sell at least 22 ads to remain profitable.

Answer:
2.27
Step-by-step explanation:
1.98+2.50+3.25 = 7.73 - 10.00 = 2.27
Answer:
$2.27
Step-by-step explanation:
Add the prices together
1.98 + 2.50 + 3.25 = 7.73
Susy owes the cashier $7.73 but payed with a $10 bill, so subtract
10 - 7.73 = 2.27
She should get back $2.27

A. 30
B. 15/2
C. 15/4
D. 225/4
Answer:
D. 225/4
Step-by-step explanation:
To complete the square (a technique that can be applied to many problems!), take half the coefficient of x and square the result.
The coefficient of x is 15. Half of 15 is 15/2. Square 15/2 to get 225/4.
Check:
[tex]x^2+15x+\frac{225}{4}=\left(x+\frac{15}{2}\right)\left(x+\frac{15}{2}\right)=\left(x+\frac{15}{2}\right)^2[/tex]

Step-by-step explanation:
Zack’s Italian Pizza Bar baked 2,000 pizzas in the first year that they were open. In the second year, they baked 3,000 pizzas and in the third year 4,000 pizzas. Write a function that could model the growth of pizzas baked, where x = 0 is the first year.
Answer:
The answer is below
Step-by-step explanation:
Let x represent the number of years, where x = 0 represent the first year. Let y represent the number of pizzas baked.
In the first year(i.e. at x = 0), 2000 pizza was baked. This can be represented by (0, 2000).
In the second year(i.e. at x = 1), 3000 pizza was baked. This can be represented by (1, 3000).
In the third year(i.e. at x = 2), 4000 pizza was baked. This can be represented by (2, 4000).
Therefore, the relationship between x and y is given by:
[tex]y-y_1=\frac{y_2-y_1}{x_2-x_1} (x-x_1)[/tex]
Using the points (0, 2000) and (2, 4000):
[tex]y-2000=\frac{4000-2000}{2-0} (x-0)\\\\y-2000=1000x\\\\y = 1000x+2000[/tex]
