If a sweatshirt normally costs $40 but it is
marked down 20%. How much would it cost?
Answer:
$32
Step-by-step explanation:
First, find 20% of 40.
20% as a decimal is 0.20 (20/100)
0.20 x 40 = 8
Now, subtract 8 from the original price.
40 - 8 = 32
Answer:
$32
40 decrease 40%
40 x (1-20%) = 40 x (1-0.2) =32

Jaylen used the seat number for each of the 6,500 fans' seats in the stands at a college football game and put the numbers in a computer program. He randomly chose 200 numbers and found that 36 of those people had also purchased a parking voucher. Estimate the number of fans in the stands at a sold-out football game that purchased a parking voucher. Explain.
Answer:
1170 seats
Step-by-step explanation:
Given
[tex]Seats = 6500[/tex]
From the computer program, we have:
[tex]Sample = 200[/tex]
[tex]Voucher = 36[/tex]
First, we calculate the proportion (p) of those that bought the voucher
[tex]Proportion = \frac{Voucher}{Sample}[/tex]
[tex]p = \frac{36}{200}[/tex]
[tex]p = 0.18[/tex]
Using the larger population (i.e. 6500 seats), the esitimate of people that have bought the voucher is then calculated as:
[tex]Estimate= Proportion * Seats[/tex]
[tex]Estimate= 0.18 * 6500[/tex]
[tex]Estimate= 1170[/tex]

Answer:
(-8) is the missing value here, so
the coordinates will be (-8,8)
Answer:
-8
Step-by-step explanation:
→ Substitute y = 8 into -4x - y = 24
-4x - 8 = 24
→ Add 8 to both sides to isolate -4x
-4x = 32
→ Divide both sides by -4 to isolate x
x = -8

a hockey team scored the following number of goals in their last 5 games: 2,3,5,3,2 which is the mean absolute deviation of the number of goals?
The required mean absolute deviation of the number of goals is 0.8.
What is mean?The mean of the values is the ratio of the total sum of values to the number of values.
The mean absolute deviation of the number of goals is a measure of how far the individual scores deviate from the mean (average) score.
To find the mean (average) score:
Mean = (2 + 3 + 5 + 3 + 2) ÷ 5 = 15 ÷ 5 = 3
Next, we find the absolute deviation for each score:
Absolute deviation for score 2: |2 - 3| = 1
Absolute deviation for score 3: |3 - 3| = 0
Absolute deviation for score 5: |5 - 3| = 2
Absolute deviation for score 3: |3 - 3| = 0
Absolute deviation for score 2: |2 - 3| = 1
Mean absolute deviation is given as,
= (1 + 0 + 2 + 0 + 1) ÷ 5 = 4 ÷ 5 = 0.8
So, the mean absolute deviation of the number of goals is 0.8.

A teacher has 396 pieces of candy. If there are 44 students, 6 of whom are boys, if divided evenly, how many pieces of candy will each student get?
Answer:
9 pieces of candy.
Step-by-step explanation:
The information about how many boys there are is irrelevant, so we can just ignore that.
The important information is that the teacher has 396 pieces of candy and that it is split between 44 students equally.
So, to solve, we just do 396 / 44 = 9.
Therefore, each student will get 9 pieces of candy.
The scale on a road map indicates that 2 inches = 30 miles. How many inches would represent 120 miles on this road map?
Answer:
8 inches = 120 miles
Step-by-step explanation:
If 2 inches is equivalent to 30 miles, then divide 120 by 30 then times the answer by two.
120 / 30 = 4
4 x 2 = 8
8 inches = 120 miles
To check;
30 x 4 = 120
8 / 2 = 4

What is the answer to Joanna's question?
Kindly find attached candy bar picture below
Answer:
6 people
Step-by-step explanation:
From the picture, each candy bar has already been divided equally into 3. Since we have 4 candy bars. The total number of divisions we have is ; (3 * 4 = 12 candy units).
Since each person is taking 2/3 of a bar, this is equal to 2 units of candy
Hence, number of people who could share the bar :
Total units or division / units person
12 / 2

Step-by-step explanation:
The solution is: 6 lbs does the crate weigh and, 18 lbs does each chair weigh.
What is equation?An equation is a mathematical statement that is made up of two expressions connected by an equal sign. In its simplest form in algebra, the definition of an equation is a mathematical statement that shows that two mathematical expressions are equal.
here, we have,
given that,
When you load 8 identical chairs into a crate, the total weight is 66 lbs. When you load 11 of those same chairs into the same crate, the total weight is 84 lbs.
let, each chair weigh = x
and, the crate weigh = y
so, we get,
the equations as:
8x + y = 66 ....(1)
11x + y = 84 ....(2)
now, solving this two equations,
we get,
subtracting (2) - (1),
3x = 18
or, x = 6
so, we have,
y = 18
Hence, The solution is: 6 lbs does the crate weigh and, 18 lbs does each chair weigh.
