Answer:

y = 0.126X - 7.119

8.63

Step-by-step explanation:

X = year, we subtract the year in the data from 1900 ;

So for the years we have :

78,79,80,90,91,96,97,107,108,109

Using technology to fit the data above, the regression model obtained is ;

y = 0.126X - 7.119

Where x = years

y = minimum hourly wage

The minimum hourly wage in 2025

Year = x = 2025 - 1900 = 125 years

y = 0.126(125) - 7.119

y = 8.631

Predicted Minimum hourly wage = 8.63

An artists builds a sculpture out of metal and wood that weighs 14.9 kilograms.3/4 of this weight is metal,and the rest is wood.
Softa [21]

Given is a sculpture that is built up of metal and wood, and the weight of this sculpture is 14.9 kilograms.

It says that three-fourth of the total weight is metal and says to find the weight of wooden part.

We can find the weight of metal part and then subtract it from the total weight to calculate the answer.

Total weight = 14.9 kilograms.

Metal part = three-fourth of total weight = \frac{3}{4} *14.9=\frac{44.7}{4} =11.175 \;kilograms

Wooden part = 14.9 - 11.175 = 3.725 kilograms.

Hence, the wooden part is 3.725 kilograms.

There are 3 counselors assigned to each group of 24 campers, how many campers would there be if there was 9 counselors ​
olya-2409 [2.1K]
There would be 72 campers because if you divided 24 by 3 it gives you 8 and than you’ll multiply 8 by 9 and it’ll give you 72.

What are the x-intercepts of y=x^2+2x-15
Sedbober [7]

Answer:

(-5,0) and (3,0)

Step-by-step explanation:

Think about it.

What two numbers multiply to -15 and add up to 2?

The answers are 5 and -3.

So plug that into the factored form of a parabola.

y=(x+5)(x-3)

To find the x-intercepts, plug in 0 for y.

(x+5)(x-3)=0

Since we are multiplying, at least one of the terms has to equal 0.

x+5=0 \\ x-3=0 \\ \\ x=-5,3

So the x-intercepts are (-5,0) and (3,0).
