It says that mean of six nos is 4.7
So, that means ( no pun intended), the average of six numbers give a value of 4.7
the same goes for the average of the other four numbers=6.5
If we're talking about the mean ( average) of all the ten numbers , we usually would need the ten numbers ( their values and their frequency) , but since its already given as mean itself , we could just add up the values.
4.7+6.5=11.2
1037 is the whole number estimate
Answer:
I'm going to assume you meant 1.5 pounds and not 15 pounds each month.
Step-by-step explanation:
1.5*6=9
C
Z and 96 are vertical angles so they equal each other. The other angle makes a straight line with the 96 degree angle so subtract from 180 to find the measure of that angle is 84. Set the expression equal to 84 and solve.
Answer:
Yes, they are independent because P(Texas) ≈ 0.45 and P(Texas/brand A) ≈ 0.45.
Step-by-step explanation:
We are given that a taste test asks people from Texas and California which pasta they prefer, brand A or brand B. The table is given in the question.
A person is randomly selected from those tested.
And we have find that are being from Texas and preferring brand A independent events or not.
Firstly, we know that these two events will be independent when;
P(Texas) = P(Texas/brand A)
Now, P(Texas) =
=
≈ 0.45
Also, P(Texas/brand A) =
=
=
≈ 0.45
Therefore, being from Texas and preferring brand A are independent events because P(Texas) ≈ 0.45 and P(Texas/brand A) ≈ 0.45.
