Answer:
The Slope Is -1.9128x
The y intercept is 99.3321
Jimmy's overall grade is 87%
The correlation coefficient is -0.979527
The data is decreasing and the model is a strong fit
Step-by-step explanation:
y = -1.9128 + 99.3321
-1.9128(6) + 99.3321
-11.4768 + 99.3321
87.8553 then round it to the nearest whole number and it is 87%
*Time is the X value on the horizontal axis. There are two data series for the Y values: Actual temperatures and and predicted temperatures.*
Yes! All the domain (or x numbers) are increasing by 1. All the range (or y numbers) are increasing my 3 each time. If you were to put it on a graph, you would see the line straight and increasing in a congruent proportion.
Total 5040 passwords can be generated when no digits are repeated
• Permutation in mathematics is an arrangement of objects in an definite order. The elements or sets or things are arranged in sequential order or linear order.
• Permutation is classified into four types :
1) where repetition is not allowed
2) where repetition is allowed
3) objects that are non distinct
4) circular permutation
• The formula for calculating permutation is n!/(n-r)!
As we are given that the password uses four digits from 0-9 and repetition is not allowed.
So, n = 10 and r = 4
Using the formula for permutation we get
= 10! / (10-4)!
= 10!/6!
= 10 * 9 * 8 * 7 * 6! / 6!
= 10 * 9 * 8 * 7
= 5040
Therefore, 5040 four digit passwords are possible when no digit is repeated.

-1,080, because they are all being multiplied by 6 :)
