Answer:

60%

Step-by-step explanation:

To find the reduction percentage, divide 12 by 20, then multiply by 100:

12/20

= 0.6

0.6(100)

= 60

So, the sweater was reduced by 60%

Answer:

60%

Step-by-step explanation:

[tex]\frac{12}{20} * \frac{x}{100}[/tex]

12 * 100 is 1200

1200/20 = 60

So, therefore the sweater was reduced by 60%.

Hope this helps, have a great day:)

Answer:

See below

Step-by-step explanation:

So you are moving the decimal to the right, right?

This action would make the number bigger.

For this explanation I will use the example 7.2

So lets move the decimal 3 to the right.

You get 7200.

Now try dividing 7200 by 100 = 72

This did not get us the original # 7.2

Now lets divide 7200 by 1000 = 7.2

Now that we got the original #, switch the operation and multiply 7.2 by 1000

7.2 x 1000 = 7200

Answer = multiplying the number by 1,000

Answer:

Data Set B

Step-by-step explanation:

Mean Absolute Deviation(MAD) can be defined as the distance between one data point (value) to the Mean in a give Data set

It can also be defined as the deviation of the mean from the data points or values given in a data set.

From the above question, we are told that:

The mean of data set A ls 43.5 and the MAD is 3.7.

The mean of data set B is 12.8 and the MAD is 4.1.

Comparing the two Data set, the Mean Absolute Deviation of Data set A is smaller than that of Data set B.

Hence, Data set B shows a greater degree of variability because the distance between a data point(value) and the mean is 4.1. This also means that the data points in Set B are more spread out compared to the data points in Set A.

Answer:

it is terminating

Step-by-step explanation:

Answer:

The following are the answer:

In option a  "No".

In option b  "Yes".

Step-by-step explanation:

In choice a:

Ax = 0 has no nontrivial solution. A would be the three-pivot matrix, it may assume, that the function has no free variable, and only if the function has had at least one free factor are their nontrivial formulas for the equations of the form Ax=0.  

It implies that since A is a 3x3 matrix, has no free variables so that it has no non-trivial choices, and Ax = 0.

In choice b:

we assume that every potential has at least one solution that is Ax=b . If A does have a three-pivot matrix, It will be a pivot element for each row and column, and for each possible b∈ R³, Ax = b has at least one solution.

Answer:

24%

Step-by-step explanation:

x (original price) = 50$

y (sale price) = 38$

p (percentage) = ?

p = (x - y) / x

p = (50-38) / 50

p = 12/50

p = 0.24

p = 24%

Step-by-step explanation:

Answer:

Yes; they have congruent corresponding angles.

Step-by-step explanation:

The two triangles are similar because their angles measure are the same. This is because 70 + 28 + 92 = 180 degrees and all Euclidean triangles angles measures must have a sum of exactly 180 degrees.

Answer:

Step-by-step explanation:

Total events = 75

A + B + C = 75  --------------(I)

State A had hosted the sporting event 9 more times then state C.

A = C + 9 ---------------------(II)

Together, state A and state C have hosted five more than four times the number of this sporting event that state b hosted.

A + C = 4B + 5  ---------------------(III)

Substitute A = C + 9 in (III)

C + 9 + C = 4B + 5

   2C + 4 = 4B  + 5

        2C  = 4B + 5 - 9

       2C  = 4B - 4

Divide the whole equation by 2

   2C/2  = 4B/2  - 4/2

        C = 2B  - 2 -------------(a)

Plugin the C = 2B - 2 in (II)

A = C +  9

A = 2B - 2 + 9

A = 2B + 7 ------------------(b)

Plugin the value of A & C from (a) & (b) in equation (I)

A + B + C = 75

2B + 7 + B + 2B - 2 = 75

Add the like terms

2B + B + 2B + 7 - 2 = 75

5B + 5 = 75

5B = 75 - 5

5B = 70

B = 70/5

B = 14

Plug in B value in equation (a)

C = 2B - 2

C = 2*14 -2

  = 28 - 2

C = 26

Plugin B value in equation (b)

A = 2B + 7

  = 2*14 + 7

 = 28 + 7

A = 35

State A has hosted 35 times

State B has hosted  14 times

State C has hosted 26 times

Answer:

no I'm pretty sure. hope it helps

Answer: No

Step-by-step explanation:

First convert 10 feet to yards and also 20 inches to yards.

10 feet to yards is 3.3 and 20 inches to yards is  0.55

Now add them to see if they equal to 4 or greater than.

0.55 + 3.33= 3.88

3.88 is less than 4 so Anis will not be able to make a fence

Step-by-step explanation:

The graph of the function h(x) = 5x² + 12 is more compact than the graph of function f(x) = x² and both the graphs represent parabolic curve along y axis.

A graph is the representation of the data on the vertical and horizontal coordinates so we can see the trend of the data.

The graph of the two functions is attached with the answer below. For the first graph, we will get the parabola whose vertex lies on the origin.

For the function h(x) = 5x² + 12 the graph will again parabolic having its vertex at ( 0,12) and the parabola is more compact than the parabola of the function F(x) = x².

Therefore the graph of the function h(x) = 5x² + 12 is more compact than the graph of function f(x) = x² and both the graphs represent parabolic curve along y axis.

Answer:

0.73 and 0.92

Step-by-step explanation:

The answers are 0.73 and 0.92 because:

1) Subtract 0.54 with 0.35, you will get 0.19

2) Therefore, we know the patter is adding 0.19 for each number

3) 0.54 + 0.19 = 0.73

4) 0.73 + 0.19 = 0.92

Hope this helps!

An arithmetic sequence is a sequence of integers with its adjacent terms differing with one common difference. The next two terms in the pattern will be 0.73 and 0.92.

An arithmetic sequence is a sequence of integers with its adjacent terms differing with one common difference.

The explicit formula for any arithmetic series is given by the formula,

aₙ = a₁ + (n-1)d

where d is the difference and a₁ is the first term of the sequence.

The given series is an arithmetic series. Therefore, the common difference between any of the two terms in the series is,

Common difference = 0.35 - 0.16 = 0.19

Now, the next term of the series will be,

Next term =  Previous term + common difference

= 0.54 + 0.19

= 0.73

Next term = 0.73 + 0.19

= 0.92

Hence, the next two terms in the pattern will be 0.73 and 0.92.
