Answer:
Step-by-step explanation:
a) P(80 < X < 110) for N(100,15)
Mean 100 sd=15
z F (x)
80 -1.333333333 0.09121122
110 0.666666667 0.747507462
P(80<x<110) 0.656296243
b. P(1.50 < X < 2.00) for N(0,1)
z F (x)
1.5 0.933192799
2 0.977249868
P(1.50 < X < 2.00) =0.04406
c. P(4,500 < X < 7,000) for N(6000,1000)
6000 1000
z F (x)
4500 -1.5 0.066807201
7000 1 0.841344746
P(4500<x<7000) 0.774537545
d. P(225 < X < 450) for N(600,100)
600 100
z F (x)
225 -3.75 8.84173E-05
450 -1.5 0.066807201
P(225<x<450) 0.066718784
Answer:
1.
Output as per boxes: 2, 2.5, 3, 3.5, 4, 4.5
Step-by-step explanation:
1.
0/4=0+2=2
2/4=0.5+2=2.5
4/4=1+2=3
6/4=1.5+2=3.5
8/4=2+2=4
10/4=2.5+2=4.5
Answer:
I would say divide the two number the round to the nearest ten
Step-by-step explanation:
Answer: The decimal 0.88888.... represented by the fraction 
Step-by-step explanation:
Since we have given that
0.888888....
So, Let x = 0.88888....=
-----(1)
Now, multiply by 10 on both sides, we get that
Now, Subtracting (1) from (2), we get that
Hence, the decimal 0.88888.... represented by the fraction
