Answer:
Percentage increase.
Step-by-step explanation:
It took the Phillips family 6 hours to drive to their vacation destination. 2 hours and 42 minutes extra because of traffic.
8 hours 42 minutes
-
6 hours 0 minutes
=
2 hours and 42 minutes
Percentage increase.
Answer:
W=5.3, l= 15.6
Step-by-step explanation:
Perimeter of a rectangle p=2(l+w)
P= 42
W= x
L= 5+2x therefore 42=2(5+2x+x)
42=10+6x , 32=6x
Make x subject of formula
X=32/6 x=5.3 there for w=5.3
Where L= 5+2x ; L=5+2(5.3)
L therefore = 15.6
Answer:
Step-by-step explanation:
<u>The line x = 3 is parallel to y- axis, the perpendicular line is going to be parallel to x- axis and will have an equation:</u>
<u>Since it passes through the point (-2, 5), it will have a = 5:</u>
- y = 5 is the line we need
Let this number be x. The next number is (x+1). And their sum is 57. Then, we have to solve this equation x+x+1=57
Emily's number was 28
Question:
A solar power company is trying to correlate the total possible hours of daylight (simply the time from sunrise to sunset) on a given day to the production from solar panels on a residential unit. They created a scatter plot for one such unit over the span of five months. The scatter plot is shown below. The equation line of best fit for this bivariate data set was: y = 2.26x + 20.01
How many kilowatt hours would the model predict on a day that has 14 hours of possible daylight?
Answer:
51.65 kilowatt hours
Step-by-step explanation:
We are given the equation line of best fit for this data as:
y = 2.26x + 20.01
On a day that has 14 hours of possible daylight, the model prediction will be calculated as follow:
Let x = 14 in the equation.
Therefore,
y = 2.26x + 20.01
y = 2.26(14) + 20.01
y = 31.64 + 20.01
y = 51.65
On a day that has 14 hours of daylight, the model would predict 51.65 kilowatt hours
