Answer:
800.8
Step-by-step explanation:
Let, the height be h.
Then, sin72 = h/842
h = sin72 * 842
= 800.7895 = 800.8

Answer:
<em>conclusion : Life expectancy of women > Life expectancy of men </em>
Step-by-step explanation:
A) Mean life expectancy of women
from the attached table
mean life expectancy of women = ∑fx / ∑f
∑fx = 1523
∑f = 20
mean = 1523 / 20 = 76.15
The line graph shows a negatively skewed distribution
B) Mean life expectancy of Men
from the attached table
mean life expectancy of Men = ∑fx / ∑f
∑fx = 1432
∑f = 20
mean = 1432 / 20 = 71.6
<em>conclusion : Life expectancy of women > Life expectancy of men </em>
Answer:
Experimental probability of head = 2 / 5 or 40%
Step-by-step explanation:
Given:
Total chances of getting head = 20 times
Number of heads come = 8
Find:
Experimental probability of head
Computation:
Experimental probability of head = Number of heads come / Total chances of getting head
Experimental probability of head = 8 / 20
Experimental probability of head = 2 / 5 or 40%
Answer:
Mary bought 9 Golden Delicious apples
Step-by-step explanation:
This can be solved by setting up a system of equations. Based on the information given, the equations would be set up as follows.

I prefer to solve using substitution, but elimination can be used as well

We can now plug in this g value to the first equation

This means mary bought 13 delicious apples. She bought 22 apples in total, so the total number minus the amount of delicious apples will give us the amount of golden delicious apples.
22 - 13 = g
9 = g
