Answer:
44.44 miles per hour.
Step-by-step explanation:
A truck driver drove 300 miles in hours.
We have to calculate the speed per hour.
First we convert hours to decimal form.
= 6.75 hours
∵ in 6.75 hours the driver drove = 300 miles
∴ in 1 hour he drove = miles
= 44.44 miles
The truck driver drove 44.44 miles per hour.

Answer:
This relationship is a function
Step-by-step explanation:
By definition a relation is defined as a function if and only if for each input value x there is only one output value y.
In this case we observe the following ordered pairs
(0.2), (1.2), (2.2) (3.2)
We see that each value x has only a value of y.
Therefore this relationship is a function
Answer:
Empirical probability of deaths cause by stroke=0.004086
Empirical probability of deaths cause by kidney disease =0.001436
Death rate due to stroke is 4 times the death rate due to kidney disease.
Step-by-step explanation:
Consider the table attached in figure
No. of deaths cause by stroke = 128300
No. of deaths caused due t kidney disease = 45100
Total population = 314 x 10⁵
Formula to calculate empirical probability:
Empirical probability of deaths cause by stroke:
Percentage of deaths cause by stroke =0.4%
Empirical probability of deaths cause by kidney disease:
Percentage of deaths cause by kidney disease =0.1%
Ratio between deaths caused to stoke to deaths caused by kidney disease is 4:1 which means death rate due to stroke is 4 times the death rate due to kidney disease.
