Answer:
Your slope would be -5/3
Step-by-step explanation:
To find the slope from two points, you would use the formula y2-y1/x2-x1
In this case, the equation would look like -12-8/3-(-9)
-12 - 8 = -20
3 - (-9) = 12
-20/12 = -5/3
Answer:
D .For every day the soap is used, the predicted mass of the soap will decrease by 1.8 grams.
Step-by-step explanation:
The given regression equation is
Predicted y = 78.5 – 1.8x where, y = mass of a bar of soap in grams and x = number of days soap has been used.
Here, slope=b=-1.8.
Slope depicts the unit increase in predicted variable due to change in independent variable.
The given slope -1.8 shows that due to change in number of days soap is used the predicted mass of the soap decreases by 1.8 units. So, we can say that "For every day the soap is used, the predicted mass of the soap will decrease by 1.8 grams".
-13k + 7k - 4 = 23 + 16k - 2
-13k + 7k - 16k = 23 - 2 + 4
-22k = 25
k = 25/-22
So you miss one day every two weeks
4 weeks in a month
2 days a month are missed
2 x 12 is 24(24 days you miss a year)
9.29 x 8 = 74.32 a day is how much you're paid.
So, if you miss 74.32 two days out of every month that'd be 148.64 because you miss two days of 74.32 and 74.32 x 2 = 148.64
12 months in a year
148.64 every month x 12 months a year
1783.68
But when I searched online, it said there is 52 weeks in a year.
If we go about the problem with 52 weeks in a year then this is the problem solution
26 days you miss
74.32 x 26
= 1932.32
(1/8)x + (1/16)x = 1
(2/16)x + (1/16)x = 1
(3/16)x = 1
x = 16/3 = 5.33333 hrs
