Answer:
It would be $1,420.83
Step-by-step explanation:
You take $34,100 and divide it by 24
( semimonthly means twice a month) so 12x2=24
so $34,100 semimonthly would be $1,420.83
Answer:
Step-by-step explanation:
From the information given:
mean life span of a brand of automobile = 35,000
standard deviation of a brand of automobile = 2250 miles.
the z-score that corresponds to each life span are as follows.
the standard z- score formula is:
For x = 34000
z = −0.4444
For x = 37000
z = 0.8889
For x = 3000
z = -2.222
From the above z- score that corresponds to their life span; it is glaring that the tire with the life span 30,000 miles has an unusually short life span.
For x = 30,500
z = -2
P(z) = P(-2)
Using excel function (=NORMDIST -2)
P(z) = 0.022750132
P(z) = 2.28th percentile
For x = 37250
z = 1
Using excel function (=NORMDIST 1)
P(z) = 0.841344746
P(z) = 84.14th percentile
For x = 35000
z = 0
Using excel function (=NORMDIST 0)
P(z) = 0.5
P(z) = 50th percentile
Answer:
the answer would be B y=x+9/4
Step-by-step explanation:x=4y-9 switch sides 4y-9=x then add 9 to both sides 4y-9+9=x+9
then 4y=x+9 simplify 4y/4=x/4+9/4 then simplify y=x+9/4 that your answer B y=x+9/4
Answer: 47 = 1 x 47 since 47 is a prime
