Answer: 2.46
Step-by-step explanation:
Formula for x-score is given by :-
, where = Sample mean , = population mean, = population standard deviation, n= sample size.
As per given , n=10
= $29,056
= $3,339
= $31,650
Then,
Hence, the z-score = 2.46

Answer: 24
Step-by-step explanation:
Number of marbles in jar = 32
Let blue marbles be represented by b.
Since there are three times as many green marbles as blue. This means that green will be = 3 × b = 3b
We then add them together. This will be:
3b + b = 32
4b = 32
b = 32/4
b = 8
There are 8 blue marbles
Since green is 3× blue. Therefore,
Green = 8 × 3 = 24 marbles
You cross multiply, so times 5•7 & 8•7 and 8•2 & 8•7
Getting 35/56 + 16/56 which equals 51/56
It would be 0.
5 times zero is zero, adding 6 will make it equal to 6.
