Answer: Probability that both tests detect the bacteria is 83.66%.
Step-by-step explanation:
Since we have given that
Probability of the first test giving accurate results = 84%
Probability of the second test is accurate = 89%
Probability of both tests detect the bacteria is given by

Hence, Probability that both tests detect the bacteria is 83.66%.

Answer: 4900 (choice D)</h3>
===================================================
Work Shown:
1 km = 1000 m
3.5 km = 3500 m ............. multiplying both sides by 3.5
(70 paces)/(50 m) = (x paces)/(3500 m)
70/50 = x/3500
7/5 = x/3500
7*3500 = 5x .............. cross multiply
5x = 7*3500
x = (7*3500)/5
x = (7*5*700)/5
x = 7*700
x = 4900
Ann takes 4900 paces to walk 3.5 km
First, rewrite the equation
with the base equal to 5. Note that:
Then

Since the bases are equal, you have that powers are equal too:

Answer: 
Answer:
2,648.448 cubic feet
Step-by-step explanation:
The cargo box of a truck is a rectangular prism. The volume of a rectangular prism is l*w*h.
If the length is 39.6 ft, the width is 7.6 ft and the height is 8.8 ft then the volume is (39.6)(7.6)(8.8) = 2,648.448 cubic feet
It just depends on the equation that you have to solve
