Answer:
The mean absolute deviation is 4
Step-by-step explanation:
The mean absolute deviation is a measure of how much a data set varies.
Step 1: Compute the mean
mean = the sum of all the terms / number of terms
mean = 94 + 86 + 95 + 99 + 88 + 90 / 6
= 552 / 6
= 92
The mean is 92
Step 2: Finding the absolute deviation
You would take each number in the data set and subtract it from the mean, take the absolute value. After you take the sum of the absolute data values
|data set #1 - mean| + |data set #2 - mean| + ... + |data set #6 - mean|
= |94 - 92| + |86 - 92| + |95 - 92| + |99 - 92| + |88 - 92| + |90 - 92|
= |2| + |- 6| + |3| + |7| + |- 4| + |- 2|
= 2 + 6 + 3 + 7 + 4 + 2
= 24
To find the mean absolute deviation you divided the sum by total number of terms...
24/6 = 4
The average (mean) is equal to the sum of all the data values divided by the count of values in the data set (which was step 1)

(Find the Probability Question)
Choose 2 girls from a class of 12 boys and 8 girls.
Step-by-step explanation:
what should be the question ?
how many different pairs of 2 girls can you pick out of 8 ?
what is the probability that a specific girl is in the picked pair ?
or is it : if you pick randomly 2 students from the class, what is the probability to have picked 2 girls ?
and there are more options.
but I assume the problem is the picking randomly 2 students.
so, it is 20 students (12 + 8). if we pick 1 student, we have a chance of 12/20 = 3/5 to pick a boy, and a chance of 8/20 = 2/5 to pick a girl.
in our experiment we pick 2 students in a row without returning the first pick into the main pool.
the probabilty for the first pick to be a girl is, as mentioned, 2/5 or 0.4.
for the second pick we have only 7 out of 19 choices to pick a girl. so, the probability to pick a girl now is 7/19.
the combination of both (non-overlapping) probabilities is done via multiplication, and the probabilty to pick 2 girls is :
2/5 × 7/19 = 2×7 / 5×19 = 14/95 = 0.147368421...

Answer:
B: 5x+5.75
Step-by-step explanation:
2 cones with fruit:
cones= x+x=2x
fruit= $1 x 2=$2
=2x+ 2
3 cones with candy and syrup:
cones= x+x+x=3x
candy= $0.75x3=$2.25
syrup= $0.50x3=$1.50
3x+ (2.25+1.50)
=3x+3.75
both of them together=
(3x+3.75)+(2x+2)= 5x+5.75

Peter has a unique computer. The screen of the computer is a square and measures twelve inches. What is the area of the entire computer screen?
A. 144 in
B. 124 in
C. 54 in
D. 48 in
Answer:
A. 144 in
Step-by-step explanation:
Squares have congruent sides.
One side is 12 inches, so all of the other sides are 12 inches.
To find the area of a square, multiply width by height. The width is 12, and the height is also 12
12 * 12 = 144
144 in ^2

Calories consumed by members of a track team the day before a race are normally distributed, with a mean of 1,700 calories and a standard deviation of 100 calories. If a normal curve is sketched using these data, what is the range for 3 standard deviations to the right and to the left of the mean?
1,400–2,000
0–3,500
1,600–1,800
1,500–1,900
Answer:
Option A is right.
Given that:
Mean = 1700
Standard deviation = 100
So, the range for 3 standard deviations to the right and to the left of the mean is:

Answer:
1000 you have to multiply and keep the number the same hope this helps
Step-by-step explanation:
10x10=100x10=1000
Answer:
314
Step-by-step explanation:
The answer would be 314 because we know that the formula for Area is time radius squared so we plug in the information stays the same as for r it is replaced with 10 inches. We start off by multiplying by the radius or 10 but before that we square it. Squaring it is taking the number and multiplying it by itself so 10x10 giving us 100. After that we can do 3.14 x 100 to get our answer of 314.

What is the mean absolute deviation of a data-set?
The mean of a data-set is given by the sum of all observations divided by the number of observations.
The mean absolute deviation of a data-set is the sum of the absolute value of the difference between each observation and the mean, divided by the number of observations.
The mean absolute deviation represents the average by which the values differ from the mean.
In this problem, the mean absolute deviation is of 1.3 inches, hence, it can be concluded that the daily rainfall volume differs from the mean by an average of 1.3 inches.

Chareese reflects figure RSUT over the y-axis and then rotates the reflected figure 180° about the origin, resulting in figure A. She states that RSUT ≅ ZYWX. Which best describes the accuracy of her congruency statement?
A: Accurate. A reflection will change the direction the vertices trace around the figure. A rotation preserves the change.
B: Accurate. A reflection preserves the direction the vertices trace around the figure. A rotation changes that direction.
C: Inaccurate. The correct congruency statement is RSUT ≅ ZXWY
D: Inaccurate. The correct congruency statement is RSUT ≅ XWYX
Answer:
B
Step-by-step explanation:
the direction of the vertices is still as it is, but when u rotate is 180 degree, the direction of the points changes. This is the same as reflecting the image over the x-axis.
Answer:
B
Step-by-step explanation:
the direction of the vertices is still as it is, but when u rotate is 180 degree, the direction of the points changes. This is the same as reflecting the image over the x-axis.
