He makes $232 because 8 x 4 =32 and 32 x 7.25 = 232
Answer:
the base value for X in the math world is 1... but you cant see it.
Step-by-step explanation:
Answer:
G. Carla, Brenda, Marci, Susan
Step-by-step explanation:
The time given for all participants are in decimals except for that of Marci and Carla which are given in the form of mixed fractions.
Convert the mixed fractions into decimals, then compare the figures together to do the ranking.
Marci =
Carla =
The first four finishers from the 1st to the 4th are:
1. Carla - 46.9
2. Brenda - 46.97
3. Marci - 46.98
4. Susan - 47.21
Let x=L.
Then let 3x+2=W
Giving you 124=(x)+(x)+(3x+2)+(3x+2)
Then simplify and solve.
124=8x+4
124-4=8x
120=8x
120/8=x
15=x
Then put that value back into the original equations to find the dimensions.
x=L
15=Length
and
3x+2=W
3(15)+2=W
77=Width
Answer:
9.48% probability that exactly 12 parts are produced in one day
Step-by-step explanation:
In a Poisson distribution, the probability that X represents the number of successes of a random variable is given by the following formula:
In which
x is the number of sucesses
e = 2.71828 is the Euler number
is the mean in the given interval.
The number of defective parts produced by a process in one day has a Poisson distribution with a mean of 10.
This means that
What is the probability that exactly 12 parts are produced in one day
This is P(X = 12).
9.48% probability that exactly 12 parts are produced in one day
