The number of light bulbs produced by a company can be modeled by the expression
1 answer:
Answer:
Expression is 3x² + 5x - 17
Step-by-step explanation:
We are told the number of lights produced by a company is;
Number of lights = 15x^3 + 16x^2 – 100x + 51
Also, number of companies that purchased the light bulbs is 5x - 3.
Thus;
The average number of bulbs purchased per company = (15x^3 + 16x^2 – 100x + 51)/(5x - 3)
I have attached the calculation using long division method to get;
3x² + 5x - 17

Answer:
Sum of squares of differences = 11239.74
Step-by-step explanation:
We are given the following data set:
63, 89, 92, 73, 79, 72, 34, 36, 94, 21, 25, 93, 22, 90, 79
We have to calculate the sum of square of the data set.
Formula:
where are data points,
is the mean and n is the number of observations.
Sum of squares of differences =
1.284444444 + 618.3511113 + 776.5511113 + 78.61777778 + 221.0177779 + 61.88444445 + 908.0177776 + 791.4844443 + 892.017778 + 1860.484444 + 1531.417778 + 833.2844446 + 1775.217777 + 669.0844446 + 221.0177779
= 11239.74
