Answer:
0.91854
Step-by-step explanation:
Given that a company is interested in evaluating its current inspection procedure on large shipments of identical items.
The procedure is to take a sample of 5 items and pass the shipment if no more than 1 item is found to be defective.
It is known that items are defective at a 10% rate overall.
If X is the number of defectives in the sample of 5, we find that X has two outcomes and each trial is independent of the other
So X is binomial with n =5, and p = 0.10
the probability that the inspection procedure will pass the shipment
= 
Answer: Either
or
depending on your teacher's preference. See the note at the bottom for more info.
=====================================
Let x be the speed limit. It is simply a placeholder. Think of it as a box with the number inside. We don't know what the number is, but we know that the largest it can be is 55. It cannot be larger than 55.
So x can be equal to 55 or it can be smaller
Put another way, x is less than or equal to 55 which is written as
(on the keyboard you would type " x <= 55 " without quotes).
---------------------------------------
Note: since negative speeds make no sense, we also must imply that x can't be negative. Your teacher may want you to write this in to clearly state it. If so, then you would also have
which when combined with the first inequality, you get this compound inequality
(basically saying "x is some speed between 0 and 55 mph"). This very clearly states the boundaries on what x can be. Though your teacher may want you to stick to the first format as its simpler.
Answer:
B
Step-by-step explanation:
The surface area is 16 because 10 plus6 eqals 16
Answer:
x = 1
Step-by-step explanation:
Using the rules of logarithms
log 
⇔ n log x
x = n ⇔ x = 
Given
3
(2x) = 3
(2x)³ = 3
(2x)³ = 2³
8x³ = 8 ( divide both sides by 8 )
x³ = 1 ( take the cube root of both sides )
x = 1
