Answer:
2^3 * 5^2
Step-by-step explanation:
We need to break 200 down into prime numbers
200 = 20*10 These are not prime
= 4*5 * 2*5 The 4 is not prime
= 2*2*5 * 2*5 This is prime
Rearranging
= 2*2*2*5*5
= 2^3 * 5^2
Linear regression line y=2.1x+130 predicts sales based on the money spent on advertising.
Linear regression represents the relationship between two variables. the value of y depends on the value of x.
x represents the dollars spent in advertising and y represents the company sales in dollars.
We need to find out sales y when $150 spends on advertising.
Plug in 150 for x and find out y
y = 2.1 x + 130
y = 2.1 (150) + 130
y= 445
The company expects $445 in sales
