Y=2/3x - 1
written in slope intercept form
6^2 + 20.1^2 =? 22.9^2
36 + 404 does NOT equal 524.41
These do NOT form a right triangle.
10.5^2 + 20.8^2 =? 23.3^2
110.25 + 432.64 = 542.89
Therefore, it is a right triangle.

Answer: N(20, 4) distribution.
Step-by-step explanation:
Normal approximation to Binomial :
The normal approximation is used for binomial distribution having parameters n and p as

if x is the random variable then x has
.
Given : As part of a promotion for a new type of cracker, free trial samples are offered to shoppers in a local supermarket.
The probability that a shopper will buy a packet of crackers after tasting the free sample : p=0.20.
Different shoppers can be regarded as independent trials.
if X is the number among the next 100 shoppers who buy a packet of crackers after tasting a free sample.
Then, Mean and standard deviation for x will be :

i.e. X has approximately an N(20, 4) distribution.
Answer:

Step-by-step explanation:
So we have the limit:

Let's remove the fractions in the denominator by multiplying both layers by (6+x)(6). So:

Distribute:

Simplify the numerator:

Both the numerator and the denominator have an x. Cancel:

Direct substitution:

Simplify:

And that's our answer.
And we're done!
