Answer:
5/14
Step-by-step explanation:
The total number of cards is 8
There are 5 blue cards
P(1st card is blue) = blue/total = 5/8
We take away a blue card
The total number of cards is 7
There are 4 blue cards
P(2nd card is blue) = blue/total = 4/7
The probability of blue blue is P(blue blue ) =
P(1st card is blue)*P(2nd card is blue) =
5/8* 4/7
20/56
We can divide the top and bottom by 4
5/14
Whenever you see the word "per" you can ALWAYS substitue in the word "divide". When you see "miles per gallon", change "per" into "divided by" to get miles divided by gallons. That is how you will solve the problem.
SO.....
300 miles ÷ 10 gallons = 30 miles per gallon
<span>f(x) = 0.3(4)x ------> f(x)=1.2x
As,
f(x)=y
So,
y=1.2x
re arranging x and y:
x=1.2y
y=1.2/x
f(-1)x= x/1.2
putting x=6:
f(-1) 6 = 6/1.2
</span><span>f(-1) 6 = 5</span>
Answer:
No, because the correlation coefficient is closer to 0 than to 1, which indicates a weak association between the variables.
