Answer:
1.) The minimum wage increased by $0.15 per year.
5.) The minimum wage in 1990 was $0.15.
7.) The minimum wage in 1990 was $3.95.
Step-by-step explanation:
given that the years between 1990 and 2009, the regression equation yˆ=0.15x+3.95 models the minimum wage.
where x = 19 years
The slope = 0.15
The intercept = 3.95
The best statement for interpretation of the slope and interpretation of the y-intercept are:
1.) The minimum wage increased by $0.15 per year.
5.) The minimum wage in 1990 was $0.15.
7.) The minimum wage in 1990 was $3.95.
Answer:
$5.40
Step-by-step explanation:
First, figure out the cost of the items with tax; for Tommy we have 20*0.08 = 1.6, add that 1.6 to the 20 and his purchase is $21.6, for John we have 25*0.08 = 2, add 2 to his 25 and his purchase is $27. To find the difference we subtract 27-21.6 = 5.4 or $5.40
Answer:
x = 5, x = -5
Step-by-step explanation:
First, you can notice both terms of the equation are divisible by 2, so you can factor it out to get:
2(x^2 - 25) = 0
You can recognize the expression x^2 - 25 as the special product for the difference of squares, so it would be factored into (x + 5)(x - 5). When we plug it in we get:
2(x + 5)(x - 5) = 0
Now, we can use the zero-product property to get two equations:
x + 5 = 0
-and-
x - 5 = 0
Solving them both we get:
x = 5, x = -5
