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)

Answer:

        Katie wants to know if people prefer cats or dogs. She is unable to ask all 3,000 people in her area, so she randomly samples 350. If 174 people say they prefer dogs, what percent of the random sample likes cats?

Step-by-step explanation:

   A population size means there are 3,000 total. A sample size means that 350 are sampled.

Answer:

∠G, ∠HGI, ∠IGH

Step-by-step explanation:

» Concepts

To name an angle, you MUST include the vertex either in the middle or have it standing by itself. To clarify, you can either call this angle ∠G, ∠HGI, or ∠IGH because they all include the vertex, G, in the middle or by itself. You put ∠HIG, which is incorrect because the vertex is not I.

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

B: 5x+5.75

Step-by-step explanation:

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:

91.1250 m^3

Step-by-step explanation:

The volume of a cube can be calculated if you know its side length. The formula is then volume cube = side3. This is simply the length of the side multiplied by itself two times.

Answer:

91.125

Step-by-step explanation:

The formula to find the volume of a cube is lwh. All the side lengths of a cube are equal. So in this case, 4.5 to the third power is 91.125.

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.

Answer:

an average of 1.3 inches

Step-by-step explanation:

Using the mean absolute deviation, it can be concluded that the daily rainfall volume differs from the mean by an average of 1.3 inches.

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.

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

Answer:

x = 30

(2x)° = 60°

x = 30°

Step-by-step explanation:

The two angles combined is a right angle, and a right angle is 90°, so we can put that into this equation:

2x + x = 90 which is the same as 3x = 90 because 2x + x = 3x

3x = 90

divide both sides by 3 so you can get x by itself

3x divided by 3 = x

90 divided by 3 = 30

you get x = 30

since x = 30, 2x is the same as 2 times 30, and that is 60.
