Answer:
Its B on e2020
Step-by-step explanation:
correct on quiz
The answer is $37,923
<span>y = 844.697x^2 + 3723.485x - 13,650
x - number of years
y - the annual profit
If x = 8, the annual profit y is:
y = </span>844.697 * 8^2 + 3723.485 * 8 - 13,650
y = 844.697 * 64 + 29,787.88 - 13,650
y = 54,060.608 + 16,137.88
y = 37,922.728 ≈ 37,923
Answer:
The value is a statistic because the 6,076 adults in public restrooms are a sample
Step-by-step explanation:
A measure that is calculated from a sample is known as sample statistic.
A study conducted and for the study 6076 adults are selected to inquire about the hand washing habit of adults. The selected 6076 adults are a sample and for this sample we computed the average 23% which demonstrates that 23% of adults did not wash their hands before exiting. So, a statistic is 23% and 6076 adults are a sample.
Answer:
6 gallons per minute
Step-by-step explanation:
Let the function that models the quantities of water, Q (in gallons) in a pool over time, t (in minutes), is
Q = a + bt ........... (1)
Now, Q(t = 0) is given to be 50 gallons.
So, a = 50 and b denotes the rate at which the quantity of water in the pool is decreasing and it is given by the slope of equation (1).
Now, two points on the graph are (0,50) and (1,44).
So, the slope = b = = - 6 gallons per minute.
Therefore, the equation of this situation is given by Q = 50 - 6t, where the slope is equal to - 6 gallons per minute. (Answer)
