Answer:

1. 5.25 - 5= 0.25

2. 5.5 - 4 = 1.5

Step-by-step explanation:

Find the mean: Add all values Divide by how many numbers there are

Last week:

2 + 3 + 3 + 3 + 4 + 4 + 7 + 7 + 7 + 7 + 8 + 8 = 63

63/12 = 5.25

This week:

2 + 2 + 2 + 3 + 3 + 4 + 4 + 6 + 8 + 8 + 9 + 9 = 60

60/12 = 5

Last week mean - This week mean:

Mean of strikes last week - Mean of strikes this week =

5.25 - 5 = 0.25

Find the Median:   Put all values in order Find the middle value  (If there are two numbers in the middle then find the mean of the two values)

Last week:

2 3 3 3 4 4 7 7 7 7 8 8

4 + 7 = 11

11/ 2 = 5.5

This week:

2  2  2  3  3  4  4 6  8  8  9  9

4 + 4 = 8

8/2 = 4

Last week median - this week median:

5.5 - 4 = 1.5

Last week median - this week median is 1.5

The character in our video multiplied the original value for black paint by 5 to get the new value for black paint. So, she also multiplied the original value for green paint by 5 to get the new value for green paint. There are multiplicative relationships, relationships related to multiplication, in a ratio table. To get from values for green and black in one ratio to values for green and black in another ratio, we can multiply both the initial values by the same number. For example, to get from the ratio 3:2 to the ratio 6:4, we multiply both the 3 and 2 by 2. And to get from the ratio 3:2 to the ratio 15:10, we multiply both the 3 and 2 by 5.

Sometimes, there are also relationships related to addition, called additive relationships, in a ratio table. To get from one value for green to another value for green, we can add 3. To get from one value for black to another value for black, we can add 2. When using the multiplicative relationship to find equivalent ratios, we can multiply both columns by the same number. But when using the additive relationship, we cannot add the same number to both columns.

Answer:

area =l×b=

(10m×14m)= 140m

Answer:

Perimeter = 33.4248cm

Area = 29.42478cm²

Step-by-step explanation:

Perimeter = half circle + rectangle length + radius + 90degree section + rectangle length + radius

radius of the circles = (14 - 10)/2 = 2

Perimeter = 2π + 10 + 2 + π + 10 + 2

Perimeter = 3π + 24 = 33.4248cm

Area = half circle + rectangle + quarter circle

Area = π(2)²/2 + 10×2 + π(2)²/4

Area = 29.42478cm²
