Answer:
d. 52.5 million cases
Step-by-step explanation:
from the data output in the question, we have the regression equation to be
log y = -151.281 + 0.076577x
y is the number of hiv cases which is in millions
x is the year of the hiv case
x = 1998
we put the value of x in the regression equation
log y = -151.281 + 0.076577(1998)
log y = -151.281 + 153.000846
log y = 1.719846
since the result is in log form,
y = 52.5 million cases
Answer: 8 hours
Step-by-step explanation:
Let x be the time taken by each person to paint the fence.
Given: Tom and Becky can paint Jim's fence together in 12 hours.
Since all people paint at the same rate, then we have the following equation ;-
Thus, the time taken by each person to paint the fence alone = 24 hours
Now, the time taken by all three paint together:-
Hence, it would take 8 hours if all three paint together.
Answer:
the length of the bridge in miles is 3.37 miles
Step-by-step explanation:
The computation of the length of the bridge in miles is shown below:
Given that
The length is 5927.261 yard
As we know that
1760 yard = 1 mile
So 1 yard = 1 ÷ 1760 mile
For 5927.261 yard, the miles would be
= 5927.261 ÷ 1760
= 3.37 miles
Hence, the length of the bridge in miles is 3.37 miles
