Answer:

660

Step-by-step explanation:

First, to find out how much money they have collected so far, you need to add 7100 + 1300 which is 8400. 8400= $8.40. So now you know that they have collected 8.40, you need to subtract 1500-840 which = 660

Hope this helps!

Algebra 1A unit 6 lesson 6
AnnyKZ [126]
1. y = -x - 2...slope here is -1. A parallel line will have the same slope

y = mx + b
slope(m) = -1
(2,-2)...x = 2 and y = -2
now we sub and find b, the y int
-2 = -1(2) + b
-2 = -2 + b
-2 + 2 = b
0 = b

so ur parallel equation is : y = -x
=========================
2. -1 = -3/2(2) + b
    -1 = -3 + b
    -1 + 3 = b
     2 = b
parallel equation is : y = -3/2x + 2
==========================
3. parallel equation is : x = 4
==========================
4. 3 = 1/2(-2) + b
    3 = -1 + b
    3 + 1 = b
    4 = b
parallel equation is : y = 1/2x + 4
===========================
5. y + 0 = 2(x - 5)
    y = 2x - 10 <== parallel line
============================
6. neither
============================
7. if ur second equation is : 2x + y = 7, then the lines are parallel
============================
8. neither
============================
9. sometimes
============================
10. never

A popular video game claims that the average time needed to reach level 10 Paladin is 3 hours with a standard deviation of 0.4 h
ASHA 777 [7]
For the answer to the question above, first, we must calculate the standard error. The standard error is standard deviation divided by the square root of the sample. In this case, it is equal to 0.178. The z-score has defined the distance from the sample to the population mean in units of standard error.

z = (3 – 2.5)/0.178 = 2.81
at this z-score, the probability is 0.9974 or
if rounded off it is 1%
I hope my answer helped
