I believe the equation is y = -3x + 0
UhhhhhhhhhhHHHHHHHHHHHHHHHHH IDK BUT GUESS AND PUT B
The Population mean is 3.3 and the Sample mean is 3.6, 3.6-3.3 is 0.3
-1/2(-4/5)
Multiply the numerators by each other and do the same for the denominators.
That is:
-1(-4)=4
And 2*5=10
Now we have 4/10
Divide the numerator and the denominator by 2 to get 2/5 which is the simplest form.
Hope this helped.
Olga worked 37.5 hours last week and earned $12.50 an hour.
[ h = the number of hours y = total earnings ]
12.50h = y
12.50(37.5) = y
468.75 = y
She earned $468.75 last week
If she gets a $2.50 per hour raise:
12.50 + 2.50 = 15.00
She gets $15 per hour.
How many hours will she have to work to make $468.75?
15h = 468.75 Divide 15 on both sides to get "h" by itself
h = 31.25
She needs to work 31.25 hours
