Answer:
81.5
Step-by-step explanation:
Answer:
0
Step-by-step explanation:
Given the points J (1,-10) and K (7, 2)
From the section formula
The y-coordinates of the point that divides the directed line segment from J to K into a ratio of 5:1 is obtained using the formula:
The y-coordinates of the point that divides the directed line segment from J to K into a ratio of 5:1 is 0.
As per the problem
The chemicals in my swimming pool use a ratio of 5 tablets of chlorine for every 14 days.
we have been asked to find
Which ratio shows the number of chlorine tablets needed for 42 days?
Since for each 14 days the number of tablets required is 5
So if you multiply the number of days by some number then, we will have to multiply the number of tablets required by the same number.
So When number of days
Then the number of tablets required for 42 days is
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
Answer: -2
Step-by-step explanation:
Remember, the more negative a number is, the farther below 0 it is getting.
So, -100 is less than -1. And in this case, -5 is less than -2.
