In an examination given to a class of 20 students, the following test scores were obtained.
45 45 50 50 55 60 70 75 75 80
80 85 85 85 85 90 95 95 95 100
a) Find the mean (or average) score, the mode, and the median score.
b) Which of these three measures of central tendency do you think is the least representative of the set of scores?
Answer:
Mean = 75
Median = 80
Mode = 85
The mode
Step-by-step explanation:
Given the data :
45 45 50 50 55 60 70 75 75 80 80 85 85 85 85 90 95 95 95 100
Rearranged data :
45, 45, 50, 50, 55, 60, 70, 75, 75, 80, 80, 85, 85, 85, 85, 90, 95, 95, 95, 100
The mean score :
ΣX / n ; n = sample size = 20
ΣX = 1500
Mean = 1500 / 20 = 75
Mode = most frequently occurring = 85 ( frequency of 4)
Median = 0.5(n + 1)th term
Median = 0.5(20 + 1)th term
Median = 0.5(21) th term
Median = 10.5th term = (10 + 11)th term / 2
Median = (80 + 80) / 2 = 160 / 2 = 80
2.) The mode

Answer:
-27
Step-by-step explanation:
Given: f(x)= -x^2+10x-16, g(x)= |11-2x^2|
f(9)= -(9)^2+10(9)-16
= -7
g(-5)= |11-2(-5)^2|
=39
Solve: 2[f(9)]-1/3[g(-5)]
= 2[(-7)] - 1/3[39]
= -27
Two angles are supplementary. One has a measure that is five times as large as the other. Find the two angle measures.
Answer:
30° and 150°
Step-by-step explanation:
supplementary means that the sum of the measures = 180
let's say 1 angle is labled ∠A and the other ∠B
m∠A + m∠B = 180°
however, m∠A = 5 * m∠B
so, by substituting that:
5*m∠B + m∠B = 180°
6*m∠B = 180°
m∠B = 30°
m∠A = 150°

1) Area of each circle = 0.5625π
There are 2 identical circles in the cylinder.
So the total area of all the circles is; 1.125π square inches
2) One side of the rectangle is; 1.5π
The other side of the rectangle is; 4 inches
The area of the rectangle is approximately; 6π square inches
3) The total area of the can is; 7.125π square inches
What is the total area of the composite shape?
We can see that the can is broken down into two circles with one atop and one beneath the rectangle. Thus;
1) Area of Circle on top and at bottom = πr² = π * 0.75²
Area of each circle = 0.5625π
There are 2 identical circles in the cylinder.
So the total area of all the circles is 2(0.5625π) = 1.125π square inches
2) One side of the rectangle is; 2πr = 2 * π * 0.75 = 1.5π
The other side of the rectangle is; 4 inches
The area of the rectangle is approximately; 4 * 1.5π = 6π square inches
3) The total area of the can = 6π square inches + 1.125π square inches = 7.125π square inches

It represents a function, as it value of x is mapped to only one value of y.The inverse is a function, as the graph is one-to-one, that is, each value of y is mapped to only one value of x.When does a graph represents a function?A graph represents a function if it has no vertically aligned points, that is, each value of x is mapped to only one value of y.
For the graph in this problem, the statement is true, hence the graph is a function.
Is the inverse a function?The inverse of a graph will be a function if the original function is one-to-one, that is, each value of y is mapped to only one value of x, meaning that the graph has no horizontally aligned points.
This is also true for this function, hence the inverse is a function.

The bakers at Healthy Bakery can make 170 bagels in 2 hours. How many
bagels can they bake in 14 hours? What was that rate per hour?
Given:
The bakers at Healthy Bakery can make 170 bagels in 2 hours.
To find:
How many bagels can they bake in 14 hours and the rate per hour.
Solution:
We have,
Number of bagels the bakers can bake in 2 hours = 170 bagels
Number of bagels the bakers can bake in 1 hours = [tex]\dfrac{170}{2}[/tex] bagels
= 85 bagels
Therefore, the average rate is 85 bagels per hour.
Number of bagels the bakers can bake in 14 hours = [tex]14\times 85[/tex] bagels
= 1190 bagels
Therefore, the bakers can bake 1190 bagels in 14 hours.

Georgie spends $160 on clothes. She pays 6.5% in tax. How much does she spend altogether?
The correct answer is $170.4
Explanation:
The total Georgie spent is equal to the money spent on clothes ($160) added to taxes (6.5% of the price of the clothes). Now, to calculate the money spend on taxes follow this process:
1. Divide the total of money spent on clothes into 100 (this number represents 100%)
160 ÷ 100 = 1.6
2. Multiply this number by the specific percentage (6.5)
1.6 x 6.5 = $10.4 (This is the money spent on taxes)
Finally, add the value of taxes and the price of the clothes:
$160 + $10.4 = $170.4

2)
-6 4/9
3)
-2 2/9
4)
6 4/9
Answer:
2
Step-by-step explanation:
The easiest thing is to convert it to an improper fraction.
-2 1/9 turns into -19/9. -4 1/9 turns into -37/9.
-19/9 - (-37/9) here you would add because you are subtracting a negative number.
-19/9 + 37/9 change it to positive and then add.
-19+37=18
it was 18/9. that simplified is 2.
