saw5 [17]

Answer:

it is clear that at 95% confidence that the bonus plan has increased the sales significantly, because if we observe you will notice that sales after is greater than sales before in all six cases.

Step-by-step explanation:

A 95% confidence interval as we have above is the range of values that we can say with utmost certainty and confidence that 95% chance it contains the true mean of the population. in other words we can say that a  95% confidence interval defines a range of values that you can be 95% certain contains the population mean.

Write an equation of the line that passes through(2,7) and (0,-5)
SVETLANKA909090 [29]

Answer:

-6x + y = -5\:or\:y = 6x - 5

Step-by-step explanation:

First, find the <em>rate of </em><em>change</em><em> </em>[<em>slope</em>]:

\frac{-y_1 + y_2}{-x_1 + x_2} = m

\frac{-7 - 5}{-2 ± 0} = \frac{-12}{-2} = 6

Then plug these coordinates into the Slope-Intercept Formula instead of the <em>Point-Slope</em><em> </em><em>Formula</em><em> </em>because you get it done much swiftly. In this case, we have a y-intercept of [0, -5], so this is a giveaway. It does not matter which ordered pair you choose:

-5 = b \\ \\ y = 6x - 5

If you want it in <em>Standard</em><em> </em><em>Form</em>:

y = 6x - 5

- 6x - 6x

_________

-6x + y = -5

_______________________________________________

7 = 6[2] + b

12

-5 = b \\ \\ y = 6x - 5

y = 6x - 5

- 6x - 6x

_________

-6x + y = -5

** You see? I told you it did not matter which ordered pair you choose because you will always get the exact same result.

I am joyous to assist you anytime.
