3x + 3 - x -7 is greater than 6.
2x - 4 is greater than 6.
2x is greater than 10.
x is greater than 5.
Hence, the answer is (A).
If the average rates were 20 and 25 miles per hour, then together they cover 45 miles of the distance they are separated by per hour. The ships will be 30 miles apart when 270 miles have been covered, so it takes 270/45=6 hours to cover the distance. 6 hours after 5 PM is 11:00 PM.
The probability that the mean of a sample of 106 randomly selected humans is lower than 98.5°F is 4.85%
<h3>What is an
equation?</h3>
An equation is an expression that shows the relationship between two or more numbers and variables.
Z score is given as:
z = (raw score - mean) ÷ (standard deviation/√sample size)
Given mean of 98.6°F, standard deviation is 0.62°F, sample size = 106
For x < 98.5:
z = (98.5 - 98.6) ÷ (0.62÷√106) = -1.66
P(z < -1.66) = 0.0485
The probability that the mean of a sample of 106 randomly selected humans is lower than 98.5°F is 4.85%

Answer:
$54.37
Step-by-step explanation:
First, need to find 15% of 47.28.
47.28 x .15 = 7.092
Then we add that to the original cost.
47.28+7.092 = 54.372
Round your answer
$54.37
Hope this helped!
