To get this answer you got to multiply each answer by .20% and then subtract the answer from what you divided .20% by and you should get the answer which is 88.002
Answer:
Mean = 84.9
Median = 89
Mode = 89
Step-by-step explanation:
89 , 76 , 89 , 89 , 100 , 71 , 80
First, we need to arrange in either ascending or descending order. In this case, let us arrange in ascending order:
71, 76, 80, 89, 89, 89, 100
1. The mean is simply the sum of all the variables divided by the number of variables
Mean = (71+76+80+89+89+89+100)/7
Mean = 594/7
Mean = 84.9
2. Median is the middle term of the distribution
Median = 89
3. Mode is the variable with the highest frequency i.e the variable that appears the most
Mode = 89
So you have 2 identical big triangles with the h = 5.75 and b = 4:
A=(1/2)bh=(1/2)*4*5.75=11.5
11.5*2=23
Then you have to smaller identical triangles with the h =2 and b=(4+4-4)/2=2
A=(1/2)*2*2=2
2*2=4
Then you have a rectangle:
A=bh=4*2=8
Add all the calculated areas:
A=23+4+8=35
The area of the shape is therefore 35 cm^2

Answer:
Step-by-step explanation:
Part A:
For Dog walking, he earns $30 for 5 hours of work.
He earns $36 for 6 hours of work.
$30/5 hours = $6/hour
$36/6 hours = $6/hour
He earns $6/hour dog walking.
For 8 hours, he earns 8 hours * $6/hour = $48
To earn $66, he works 66/6 = 11 hours.
5 30
6 36
8 48
11 66
Part B:
He earns $7/hour for yard work, so multiply the number of hours by 7 to find the money he earns.
Table for yard work
Hours Money
5 $35
6 $42
8 $56
Part C:
For 5 hours, he earns $35 for yard work and $30 as a dog walker.
$35 - $30 = $5
16 1/5 seconds = 16.2 seconds
19.8 - 16.2 = 3.6
Paloma is 3.6 seconds faster than Savannah in the 100-meter dash.
