Find 72% of 50<br>(REEEEEE)​
Snowcat [4.5K]

Answer:

The answer is 37.44

Step-by-step explanation:

Step 1: Divide 52 by 100

In this case, the number that we are "comparing" to 100 is 52, so we must first normalize the number by dividing it by 100. The operation we have to solve is this:

52

100

=

52

÷

100

=

0.52

Step 2: Multiply 0.52 by 72 to get the solution

Now that we have our normalized number, 0.52, we just have to multiply it by 72 to get our final answer. The forumla for this is obviously quite simple:

0.52

×

72

=

37.44

What is the percent of change from 4,000 to 600?<br> work too plz
xenn [34]
\frac { n }{ 100 } \cdot 4,000=600\\ \\ 4,000\cdot n=60,000\\ \\ Therefore:\\ \\ n=\frac { 60,000 }{ 4,000 }

\\ \\ =\frac { 60\cdot 1,000 }{ 4\cdot 1,000 } \\ \\ =\frac { 60 }{ 4 } \\ \\ =15

As 15% of 4,000 is 600, the percentage change was -85%.

Thirty Mercedes and Audi participated in a 30 mile race. The average driving speed of the Mercedes and Audi were recorded. A ran
vladimir1956 [14]

Answer:

Median for sample 1 = 142

Median for sample 2 = 134

Step-by-step explanation:

For Sample 1:

For finding median, the data is first arranged into ascending or descending order. We are arranging the data in ascending order.

120, 130, 132, 136, 139, 142, 142, 144, 156, 165, 167

The formula for calculating the term which will be median is:

Median= ((n+1)/2)

Here in sample 1, n=11

So, putting n=11 in the formula

= ((11+1)/2)

= (12/2)

=6th term

The sixth term is 142, so

Median of sample 1=142

For Sample 2:

For finding median, the data is first arranged into ascending or descending order. We are arranging the data in ascending order.

112, 112, 113, 114, 125, 134, 141, 145, 146, 163, 165

The formula for calculating the term which will be median is:

Median= ((n+1)/2)

Here in sample 2, n=11

So, putting n=11 in the formula

=((11+1)/2)

=(12/2)

=6th term

The sixth term is 134, so

Median of sample 2=134

Find the gradients of line a and b
gayaneshka [121]

Answer:

Gradient of A: 2

Gradient of B: -1

Step-by-step explanation:

Gradient = change in y/change in x

✔️Gradient of A using two points on line A, (2, 5) and (0, 1):

Gradient = (1 - 5)/(0 - 2) = -4/-2

Simplify

Gradient of A = 2

✔️Gradient of B using two points on line B, (0, 5) and (5, 0):

Gradient = (0 - 5)/(5 - 0) = -5/5

Simplify

Gradient of B = -1
