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

The perimeter of the hallway is 10 4/10 meters. What is the width, in meters, of the hallway?
Romashka [77]
So you have two of those--when you add those together, you get "seven and eight-tenths," or 7.8 The 2 shorter sides are what's left to still measure. If the total perimeter is 10.4, you get the shorter sides by: 10.4 - 7.8 = 2.6, but REMEMBER, the 2.6 is BOTH shorter sides added together, so each ONE of them is 1.3 SO... your hallway/rectangle is 3.9 meters on each long side, and 1.3 meters on each short side. i hope this helps you

Find value of x and y
marshall27 [118]

Answer:

x = 17\sqrt{3}, y = 34

Step-by-step explanation:

Since the triangle is right use trig ratios to find x and y

note exact values sin30° = \frac{1}{2}, tan30° = \frac{1}{\sqrt{3} }

sin30° = \frac{opposite}{hypotenuse} = \frac{17}{y}

multiply both sides by y

y sin30° = 17 ( divide both sides by sin30° )

y = \frac{17}{\frac{1}{2} } = 34

tan30° = \frac{opposite}{adjacent} = \frac{17}{x}

multiply both sides by x

x tan30° = 17 ( divide both sides by tan30° )

x = \frac{17}{\frac{1}{\sqrt{3} } } = 17\sqrt{3}
