If b-10=5, what is the value of b+6
Answers
15+6=21
15 minus 10 comes to an answer of 5. So that means that, b is equal to 15. If you add 15 and 6, you will get a sum of 21.

The greyhound's average acceleration will be;
⇒ Acceleration = 12.62 m/s²
What is an expression?
Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.
Given that;
A greyhound can go from a state of resting to running at 19.44 meters per second in 1.54 seconds.
Now,
Since, A greyhound can go from a state of resting to running at 19.44 meters per second in 1.54 seconds.
Hence, Initial velocity = 0
Final velocity = 19.44 meter per second
And, Time = 1.54 seconds
Since, Acceleration = Change in velocity / Time
Hence, We get;
⇒ Acceleration = Change in velocity / Time
⇒ Acceleration = (19.44 - 0) / 1.64
⇒ Acceleration = 19.44 / 1.64
⇒ Acceleration = 12.62 m/s²
Thus, The greyhound's average acceleration will be;
⇒ Acceleration = 12.62 m/s²

The fifth term of a sequence that is represented by f(n) = 5n - 2 will be 23.
What is a function?
A function is an assertion, concept, or principle that establishes an association between two variables. Functions may be found throughout mathematics and are essential for the development of significant links.
The sequence is formulated in the function f(n) is given as,
f(n) = 5n - 2
The fifth term of a sequence is calculated as,
f(5) = 5 x 5 - 2
f(5) = 25 - 2
f(5) = 23
The fifth term of a sequence that is represented by f(n) = 5n - 2 will be 23.
More about the function link is given below.
#SPJ3
My best guess would be to plug in 5 into n.
So:
f (n) = 5n-2
f (5) = 5 (5) -2
f (5) = 25-2
f (5) = 23
This is my GUESS. I'm not sure how to do this problem (it's been a while since I've done this).
So PLEASE get a second opinion or ask a teacher!
Hope this helped!

#1:
We are trying to find the MAD for each set of the teachers' grades. To find the MAD (again) find the mean of the teachers' grades. Then, take each of the teachers' grades and find the absolute value of the difference between that grade and the mean grade. Add the differences up, and divide the result by the number of teachers (10).
Do the first table first (first things first!). Find the mean by adding up the grades and dividing them by the number of teachers (10).
76 + 81 + 85 + 79 + 89 + 86 + 84 + 80 + 88 + 79 = 827
827/10 = 82.7
The mean grade for the first table is 82.7.
Now, we need to find the absolute value of the difference between each of the teachers' grades and the mean.
82.7 - 76 = 6.7
82.7 - 81 = 1.7
85 - 82.7 = 2.3
82.7 - 79 = 3.7
89 - 82.7 = 6.3
86 - 82.7 = 3.3
84 - 82.7 = 1.3
82.7 - 80 = 2.7
88 - 82.7 = 5.3
82.7 - 79 = 3.7
Now, we need to add up the result.
6.7 + 1.7 + 2.3 + 3.7 + 6.3 + 3.3 + 1.3 + 2.7 + 5.3 + 3.7 = 37
Now, we divide the result by the number of teachers.
37/10 = 3.7
So the MAD for the first table is 3.7.
Now we do the same thing for the second table.
79 + 82 + 84 + 81 + 77 + 85 + 82 + 80 + 78 + 83 = 811
811/10 = 81.1
Bad grades.
81.1 - 79 = 2.1
82 - 81.1 = 0.9
84 - 81.1 = 2.9
81.1 - 81 = 0.1
81.1 - 77 = 4.1
85 - 81.1 = 3.9
82 - 81.1 = 0.9
81.1 - 80 = 1.1
81.1 - 78 = 3.1
83 - 81.1 = 1.9
Add.
2.1 + 0.9 + 2.9 + 0.1 + 4.1 + 3.9 + 0.9 + 1.1 + 3.1 + 1.9 = 21
21/10=2.1
Now, we compare the MAD's. If the MAD for the second table is greater than the MAD for the first table, then the teachers have not improved/were sleeping. If not, then the teachers have improved/got lucky.
Hooray! They improved/got lucky, by 1.6 points to be precise.
#2:
Remember from the previous answer I gave (the other question you asked) the example with a MAD of 0? That's because they were all exactly on the mean (4 + 4 + 4 + 4 + 4 + 4 + 4 + 4 + 4 + 4 = 40, 40/10 = 4, MAD = 0). Therefore, if the MAD of the teachers' grades was zero, that means they all got the same score! Hooray! Mission accomplished. Or the common core machine has succeeded in producing identical copies of teachers.
Backword
I hope you know what the MAD is now.
