First change them to the same denominator....
2×3 6
__ = __
5×3 15
1×5 5
__ = __
3×5 15
6/15+ 5/15= 11/15.
So the sum is 11/15
Answer: -0.36
Step-by-step explanation:
Given: Mean : 
Standard deviation : 
We know that the formula to calculate the z-score is given by :-

For x=8.2 minutes, we have

Hence, the z-score for this amount of advertising time = -0.36
Answer:
domain is (xo ≤ x ≤ 0.45 )
range is (xo ≤ y ≤ 8.1 )
Step-by-step explanation:
given data
constant speed = 18 miles per hour
total time = 27 minutes = 0.45 hour
solution
we consider here Domain number of hours = x and Range distance traveled = y
we apply here distanace formula that is
Distance = speed × time .........................1
put here value
Distance = 18 × 0.45 = 8.1 miles
and no of hours x = 0 to 0.45 hours
so here
So domain is (xo ≤ x ≤ 0.45 )
and
Distance is 0 to 8.1 miles
So range is (xo ≤ y ≤ 8.1 )
<em>x equals 22</em>
