PLEASE HELP ME WITH THIS QUESTION.. the points should be more than ten NO LINKS UGH

Please help me understand how to do this with an easy explanation

ASHA 777 [7]

Answer:

10 and 10

Step-by-step explanation:

So for the first one, 1-(-9), the two subtraction signs cancel each other out and are turned into an addition symbol. The new equation would now be the absolute value of 1 + 9. As we know, 1 + 9 is 10, and the absolute value of 10 is 10. The absolute value just means how many spaces the number is away from 0, and it will always be positive.

For the second one, -9 -1 would equal -10. Even though -10 is negative, the absolute value will always be positive, so the absolute value of the second one is also 10.

Hope this helps and let me know about any questions!

The manager of music is giving away 255 music downloads at its grand opening event.

Andreas93 [3]

30 people will receive 1 music download each.

Solution:

Given, the manager of music is giving away 255 music downloads at its grand opening event.

The manger gave the greatest possible number of music downloads to each of the first 75 customers,

Now, suppose, manager gave 4 downloads each for first 75 customers.

Then, total downloads = 75 x 4 = 300 downloads, which is greater than 255, so giving 4 to 1st 75 is not possible.

Now, suppose, he gave 3 to each customer, then total downloads = 75 x 3 = 225, it is possible

So, manager will give 3 downloads each to 1st 75 customers.

Then remaining downloads = 255 – 225 = 30 downloads, then 30 people can use them.

Hence, 30 people will receive 1 music download each.

What is the formula for ANOVA

Sergio039 [100]

P = 3
n = 5
N = 15
x ¯ = 16
SST = ∑n(x−x ¯ ) 2 
SST = 5(12−16) 2 +5(16−16) 2 +11(20−16) 2 
= 160
MST = SSTp−1 
MST = 1603−1 
= 80
SSE = ∑(n−1)S 2 
SSE = 4*4 + 4*1 + 4*16
= 84
MSE = SSEN−p 
MSE = 8415−3 
MSE = 7
F = MSTMSE 
F = 807 
= 11.429

Write rule for the linear function in the table

ivann1987 [24]

The generic equation is:
y-yo = m (x-xo)
Where,
m = (y2-y1) / (x2-x1)
m = (0-1) / (4-3)
m = (- 1) / (1)
m = -1
The ordered pair is:
(xo, yo) = (4, 0)
Substituting values:
y-0 = -1 * (x-4)
y = -x + 4
Answer:
y = -x + 4
option 1
