A teacher surveyed her class after they had taken a vocabulary test. Eighteen of the students claimed they had studied at least one hour for the test. The remaining twelve students admitted that they had not studied for the test at all. The test results (expressed as a percent) for the two groups are shown below.
Studied: 87, 100, 94, 79, 92, 100, 95, 83, 89, 99, 100, 91, 89, 95, 100, 93, 96, 83
Did Not Study: 82, 72, 45, 91, 58, 83, 65, 87, 90, 77, 73, 89
Part 1: Calculate the mean of the group that did not study, rounded to the nearest tenth.
Part 2: Calculate the mean absolute deviation of the group that did not study, rounded to the nearest tenth.
Part 3: How many of the scores (from the group that did not study) are more than two mean absolute deviations from the mean?
Answer:
Didn't study: 76%
Mean absolute deviation: 11.2
Step-by-step explanation:
To find the mean, add all the scores from the people who didn't study and divide them by 12 (the total number of students who didn't study). You will get 76%To find the MAD, use the formula for MADTo answer the third, line them up in order. 45, 58, 65, 72, 73, 77, 82, 83, 87, 89, 90, 91. MAD is the average difference between the numbers. So, to find this answer, subtract two of the MAD's from the mean of 76%. 76-22.4 = 53.6. So, only one is more than two MAD's away from the mean of 76%.Felix has a bucket of golf balls. The table shows the number of golf balls of each color in the bucket.
Felix selects a golf ball at random. Based on the information on the table, which statement is true?
Answer:
C
Step-by-step explanation:
reason why it is not the others :
A. green is equal to a total of 18 While the rest combined are equal to 23. 23>18
B. To be equally likely, they all need to have the same Value, Which they do not.
D. this statement is Basically saying white times 7 is equal to green.
.
11 x 7 is 77 not 18.

What is the slope of the line shown above?
Answer:
The slope of the line is 2/3x
Step-by-step explanation:
To find the slope, you need to choose two points and find the change of y over the change of x (also know as rise/run).
Let's focus on points (-3, -1) and (0, 1).
To get from the first point to the other, you would need to move 2 units up, and 3 units to the right.

Given cosθ = .876 and tanθ = -4.731 determine sinθ
Answer:
[tex]sin\theta[/tex]= -4.144356
Step-by-step explanation:
[tex]tan\theta=\frac{sin\theta}{cos\theta}[/tex]
Therefore:
[tex]sin\theta = tan\theta.cos\theta[/tex]
[tex]sin\theta[/tex] = -4.731 × 0.876
[tex]sin\theta[/tex] = -4.144356

Which Scentence is true about an obtuse triangle?
A. All angles measure more than 90°.
B. All angles measure 90°.
C. One angle measures more than 90°.
D. One angle measures 90°.
E. All angles measure less than 90°.
Answer:
C, one angle measures more than 90 degrees.
Step-by-step explanation:
All triangles have two acute angles (less than 90 degrees)
so that eliminates A and B.
A right triangle has one 90 degree angle, so it's not D.
Obtuse is more than 90 degrees so there goes E.

Answer:
X= 17
Step-by-step explanation:
Answer:
Hello Love! Sense this is a Suplementary angle you must know it will add up to equal 180 so we already have 1 angle that is 95 degrees so we will subtract that and get 85 so we must know that 5 multiplied by x will equal 85 so I do 85 divided by 5 and get 17 I check my work and do 17 x 5 and that gets you 85 so 17 is our answer

The Lunchroom Murder
On an otherwise uneventful Thursday afternoon police heard a shot inside the local bistro, Ernie’s Lunchroom. They rushed in and found the scene shown in Figure 1.4.
They identified the body as that of a prominent racketeer named Fannin. Ernie, who is both the owner and only employee, had only one fact to tell: the murderer had leaned against the wall while firing at point-blank range. The imprint of his hand is in clear view.
The police have also noticed that the cash register had just been rung up at $8.75.

Create and Solve an equation to find the unknown angle.
Answer:
Equation: 2x + 3x + 10 = 180
x = 34
Top angle = 68 degrees
Bottom angle = 112 degrees
Step-by-step explanation:
The two angles add to 180, so set them equal to 180.
2x + 3x + 10 = 180
5x + 10 = 180
- 10 - 10
5x = 170
/ 5 / 5
x = 34
Plug x into angles,
2(34) = 68
3(34) + 10 = 112
