Trudy has been training for an upcoming marathon. She has kept track of how many miles she runs every day for the past two weeks:
12, 15, 7, 14, 12, 3, 16, 15, 19, 20, 12, 9, 18, and 21.
a. Calculate the mean and median for this data.
Mean:
Median
b. Calculate the Quartile 1 (Q1)
Quartile 2 (Q2)
d. What is the IQR (Interquartile Range):
Answer:
Kindly check explanation
Step-by-step explanation:
Given the data:
12, 15, 7, 14, 12, 3, 16, 15, 19, 20, 12, 9, 18, 21
Reordering the data:
3, 7, 9, 12, 12, 12, 14, 15, 15, 16, 18, 19, 20, 21
Mean = Σx / n = 193 / 14 = 13.76
The Median :
1/2(n+1)th term
15/2 = 7.5th term
(14 + 15) / 2 = 14.5
First quartile (Q1) :
1/4(n+1)th term
15/4 = 3.75th term
= 12
Q3 :
3/4(15)th term = 11.25 th term
Q3 = 18
Interquartile range = Q3 - Q1
Interquartile range = 18 - 12 = 6

Answer:
y = 0.35x + 18.99
Step-by-step explanation:
our y intercept is 18.99 bc thats what we start with at 0 letters
then our b or slope is 0.35 bc thats how much each letter costs. you can find it by subtracting 2 letters from 1 letter ( 19.69 - 19.34 = 0.35)

Jenna ordered four pizzas for $8.55 each, including tax. If she wanted to give a
15% tip, what would her total bill be?
Given:
Cost of each pizza including tax = $8.55
Number of pizzas = 4
Tip = 15%
To find:
Her total bill.
Solution:
We have,
Cost of 1 pizza including tax = $8.55
Cost of 4 pizza including tax = [tex]4\times \$8.55[/tex]
= [tex]\$34.2[/tex]
It is given that she wanted to give a 15% tip. So, tip is 15% of $34.2.
[tex]\dfrac{15}{100}\times \$34.2=\$5.13[/tex]
Thus, the amount of tip is $5.13.
Now the total amount of bill is:
[tex]\text{Total amount of bill}=\text{Cost including tax}+\text{Tip}[/tex]
[tex]\text{Total amount of bill}=\$34.2+\$5.13[/tex]
[tex]\text{Total amount of bill}=\$39.33[/tex]
Therefore, the total amount of bill is $39.33.

When the rate is Rs 210 per piece, a certain sum of money can buy 16 pieces of
Tshirts. If the rate increases to Rs. 280 per piece, how many pieces of T-shirts
can be bought with the sum?
Answer:
12 pieces of T-shirts can be bought with the sum.Step-by-step explanation:
Given that:
The rate is Rs 210 per piece, a certain sum of money can buy 16 pieces of T-shirts.To Find:
If the rate increases to Rs. 280 per piece, how many pieces of T-shirts can be bought with the sum?Let us assume:
x pieces of T-shirts can be bought with the sum.Finding the number of T-shirts bought:
According to the question.
Rate × Pieces of T-shirts = Rate × Pieces of T-shirts
⟶ 210 × 16 = 280 × x
⟶ 3360 = 280x
⟶ x = 3360/28
⟶ x = 12
Hence,
If the rate increases to Rs. 280 per piece, 12 pieces of T-shirts can be bought with the sum.please help me on this problem

Answer:
For part A, you could decompse the figure into a rectangle and two triangles.
for Part B, its the first one.
Step-by-step explanation:
If you split up the figure into two parts then you will get 2 triangles and a rectangle. The area of 1 triangle is
A=1/2xbh
but there are two triangles so it would be 2(1/2x bh).
you can then multiply tht by the areaof the rectangle and get
2(1/2x12*5)+(16*12)

Sphere P has a radius of 5 inches. Find the area of the cross section formed by the intersection of a
plane 3 cm above the center of sphere P and parallel to its equator.
O None of the other answers are correct
O 16pi in
O4pi in
O 7pi in
O 9pi in
Answer:
pi*16 in^2
Step-by-step explanation:
In the image, we can see a triangle rectangle.
Where one cathetus is equal to 3 inches, the hypotenuse is equal to the radius of the sphere, 5 inches, and the other cathetus is the radius of the cross-section of which we can find the area.
Using the Pythagorean theorem, we will have that:
x^2 + (3in)^2 = (5in)^2
x = √( (5in)^2 - (3in)^) = 4 in
Then the radius of the cross-section is 4 inches.
And we know that the area of a circle of radius R is:
A = pi*R^2
Then the area of the cross-section will be:
A = pi*(4in)^2 = pi*16 in^2
Then the correct option is the first one.
A jar contains 8 red marbles, 10 blue marbles, and 2 yellow marbles. One marble is chosen at random. The color is recorded in the table and then it is returned to the jar. This is repeated 40 times. Based on this data, what color marble is likely to be chosen next? Why
Red: 14
Blue: 16
Yellow: 10
Answer:
blue is more likely to be chosen because there are more of them than the other colors

A TV that was selling for $222 was discounted 75%. What is the sale price of that TV?
Answer:
$55.50
Step-by-step explanation:
The rate is usually given as a percent.
Step 1: Multiply the rate by the original price.
[tex]75\% \times 222 = 166.5[/tex]
Step 2: Subtract the discount from the original price.
[tex]222 - 166.5 = 55.5[/tex]
Therefore, the sale price of that TV is $55.50

Evaluate the expression.
9!/3!
A. 3
B. 6
C. 60,480
D. 362,874
The value of the expression 9!/3! is 60480.
Option C is the correct answer.
What is an expression?An expression contains one or more terms with addition, subtraction, multiplication, and division.
We always combine the like terms in an expression when we simplify.
We also keep all the like terms on one side of the expression if we are dealing with two sides of an expression.
Example:
1 + 3x + 4y = 7 is an expression.
3 + 4 is an expression.
2 x 4 + 6 x 7 – 9 is an expression.
33 + 77 – 88 is an expression.
We have,
9!/3!
This can be written as,
9! = 9 x 8 x 7 x 6 x 5 x 4 x 3 x 2 = 362880
3! = 3 x 2 x 1 = 6
Now,
9!/3! = 362880/6 = 60480
Thus,
The value of the expression 9!/3! is 60480.

Vaughn is calculating the volume of the cylinder below using the following work.
51 cm
24 cm
V = 3.14(12)(5)
= 3.14(144) (5)
= 2,260.8 cm
What was Vaughn's first error?
He confused the height and the diameter.
He squared 12 instead of 24.
He applied the exponent before multiplying 12 and
5.
He used the wrong units in his final answer.
Answer:
He confused the height and diameter
Step-by-step explanation:
Given that,
The radius of the cylinder, r = 2.5 cm
Height of the cylinder, h = 24 cm
The volume of the cylinder is given by the formula as follows :
[tex]V=\pi r^2 h\\\\=3.14\times (2.5)^2\times 24\\\\=471\ cm^3[/tex]
Vaughn is confused in diameter and the height of the cylinder. He takes radius as 12 cm and height as 5 cm which is wrong. Hence, the correct option is (a).
