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
Answer: 3/10. -2 3/5 = -2 6/10. -2 6/10 - -2 3/10 = - 3/10. -3/10 = 3/10 away on a number line
Answer:
1. 
2. 
3. 
Step-by-step explanation:
Write in exponential form
Using the law of logarithm which says if
then
By comparison;
A = 16; b = 2 and x = 4
The expression 
becomes
Write in exponential form
Applying the same law as used in (1) above;
A = 2; b = 16 and 
The expression 
becomes
Write in logarithm form
Using the law of logarithm which says if
then
By comparison;
b = 2; x = z and A = y
The expression 
becomes
Answer:
20 questions.
Step-by-step explanation:
Let x be the number of questions on the quiz.
85
% means 85 out of 100 (or 85/
100 )
85/
100
= 3/x
--->100-85=15
--->15/3=5
--->100/5=20
Meaning each question was worth 5% and there were 20 questions.
