The Associative Property allows you to "regroup" addition and multiplication problems. You can group this problem in two other ways,
(8 + 4) + 3 and (8 + 3) + 4.
Answer: Second option.
Step-by-step explanation:
Given the folllowing Linear Equation:

You need to substitute the coordinates of each point given in the options into the equation and then evaluate.
1) Substituting
into the equation, you get:

2) Substituting the point
. you get:

3) Apply the same procedure using the point
:

4) Apply the same procedure using the point 

5) Substituting
into the equation:

Therefore, the point
is not on the given line.
Answer:
Step-by-step explanation:
High in the Rocky Mountains, a biology research team has drained a lake to get rid of all fish. After the lake was refilled, they stocked it with an endangered species of Greenback trout. Of the 2000 Greenback trout put into the lake 400 were tagged for later study. An electroshock method is used on individual fish to get a study sample. However, this method is hard on the fish. The research team wants to know the smallest number of fish that must be electroshocked to be at least 50% sure of getting a sample of two or more tagged trout.
we have to find out smallest number fish (n) that must be electroshoked to be atleast 50% &
species of Greenback trout of the 2000 greenback trout put into the lake 400

Step-by-step explanation:
Given : The probability of having clear sunny skies in Seattle in July : p= 0.40
The number of days spent in Seattle in July: n= 18
a) Using, Binomial probability formula : 
The probability of having clear sunny skies on at least 13 of those days:-




b) On converting binomial to normal distribution, we have

Let x be the number of days having clear sunny skies in Seattle in July.
Then, using
we have

P-value =
