19+3.5-5 [ Dividing 7 with 2 yields 3.5].
Answer:
Step-by-step explanation: The mean (average) of a data set is found by adding all numbers in the data set and then dividing by the number of values in the set.
The solution of the quadratic equation 2x² + 8x = x² - 16 is given as a negative of 4.
<h3>What is a factorization?</h3>
It is the method to separate the polynomial into parts and the parts will be in multiplication. And the value of the polynomial at this point will be zero.
The equation is given below.
2x² + 8x = x² - 16
Then on simplifying, we have
x² + 8x + 16 = 0
x² + 4x + 4x + 16 = 0
(x + 4)(x + 4) = 0
(x + 4)² = 0
x = -4

Answer:
Best prediction is 8.5 hours.
Step-by-step explanation:
Since there is no samples for the age of 16 years, the best estimate (prediction) would be to interpolate: compute the average between values of the neighboring ages, namely 8 and 9 (approximately). The closest choice to an average like that is 8.5 hours.
