You have 18 rainy out of 90 total. You need to simplify each term.
18 = 1, 2, 3, 6, 9, 18
90 = 1, 2, 3, 5, 6, 9, 10, 15, 18, 30, 45, 90
Now find the largest number that is common. That would be 18. Divide both numbers by 18
18/18 = 1
90/18 = 5
So the simplified ration is 1/5
From equation 1 e=23-6f
sub 1 into 2. 2(23-6f)-f=7
46-12f-f=7
46-7-12f-f=0
39-11f=0
39=11f
then u divide both side by 11
therefore f=3.55
subtitude f in 1
6(3.55)+e=23
21.3+e=23
e=23-21.3
e=1.7
Answer:
b.
The mean increases by $1,696.30, the median increases by $79.
Step-by-step explanation:
THe mean of the 7 wins is given by
: 767+477+340+680+464+207+635/7
this equals: 510,
the new mean will be
767+477+340+680+464+207+635 +10000/8
which comes out to be:
1696.25
This is bigger than the previous mean by :
1186.25
Now the median of the first 7 observations would be:
477
of the 8 observations it woulf be
477 + 635/2
which comes out to be 79
Answer:
3750 apples
Step-by-step explanation:
Prob (Apple AAA rating) = AAA rated apples / Total Apples
25 / 330 = 0.075
Expected apples rated AAA from 50000 apples = P(AAA rating) x Apples no.
0.075 x 50000
3750
