Kazeer [188]3 years ago
3 0

Answer:

86

Step-by-step explanation:

Subtract 322 from 408

8-2=6

we cant subtract 2 from zero so we take 1 from the next

10-2=8

3-30

86

Hope this helps! (Brainliest please!)

1/2 inch= 3 feet what is the length for 7 inches
Mrrafil [7]
If \frac{1}{2} inch is equal to 3 feet, then 1 inch = 6 feet because \frac{1}{2} * 2 = 1 and 3 * 2 = 6.

Thus 1 x 7 = 7, and 6 x 7 = 42.

42 feet.

In one method of a procedure called acceptance sampling, a sample of items is randomly selected without replacement and the enti
jekas [21]

Answer:

X \sim Hyp (N = 810, M=102, n=4)

P(X=0) = \frac{(102C0)(810-102 C 4-0)}{810C4}  

And solving we got:

P(X=0)= \frac{(102C0) (708C4)}{810C4} = 0.583

So then for the problem given the probability that the entire bath will be accepted (none is defective among the 4) is 0.583

Step-by-step explanation:

For this case we can model the variable of interest with the hypergeometric distribution. And with the info given we can do this:

X \sim Hyp (N = 810, M=102, n=4)

P(X=k)= \frac{(MCk)(N-M C n-k)}{NCn}  

Where N is the population size, M is the number of success states in the population, n is the number of draws, k is the number of observed successes  

And for this case we want to find the probability that none of the scales selected would be defective so we want to find this:

P(X=0)

And using the probability mass function we got:

P(X=0) = \frac{(102C0)(810-102 C 4-0)}{810C4}  

And solving we got:

P(X=0)= \frac{(102C0) (708C4)}{810C4} = 0.583

So then for the problem given the probability that the entire bath will be accepted (none is defective among the 4) is 0.583
