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!

Answer: 0.0016
Step-by-step explanation:
Given the following :
Population mean(m) = 196
Population Standard deviation (sd) = 32
Number of sample (n) = 18
Sample mean (x) = Total weight of sample / number of samples = 3928 / 18 = 218.2
Obtaining the test statistic (z) :
Z = [(x - m) / (sd/√n)]
Z = [(218.2 - 196) / (32/√18)]
Z = [(22.2 / 7.5424723)]
Z = 2.943
Hence,
P(Z > 2.94) = 1 - P(Z < 2.94)
= 1 - 0.9984
= 0.0016

Answer: True</h3>
====================================================
Explanation:
For example, let's say we want to multiply 11 times 12.
We could decompose the 12 like this
11*12 = 11*(10+2) = 11*10+11*2 = 110+22 = 132
or we could decompose the 11 like this
11*12 = (10+1)*12 = 10*12+1*12 = 120+12 = 132
Either way, we see that 11*12 = 132
-------------
In general, the distributive property says
a*(b+c) = a*b+a*c
which is the same as saying
(b+c)*a = b*a + c*a = a*b + a*c
This flip works because we can multiply in any order.
