Can you please take a picture of the question?
There are 4 jacks and 4 eights so with replacement:
P(Jand8)=(1/13)^2=1/169
Answer:
1/5
Step-by-step explanation:
Note that this graph goes through (0, 0) and (2/5, 1/2).
Thus, the slope of the graph is m = rise / run = (1/2)/(2/5) = 1/5.
This m = 1/5 is ALSO the constant of proportionality.
In triangle ABC:
∠1 = 90°
According to the angle sum property:
∠1 + ∠2 + ∠3 = 180
Since angle 1 is 90 degrees
∠2 + ∠3 = 180 - 90
∠2 + ∠3 = 90° [∠1 + ∠2 + ∠3 = 180]
OK, here we go. Golf Club first
You subtract the total amount they need to raise, by the amount they already have:
2620 - 1225 = $1395.00 to go
Divide that number by the price of golf balls to find out how many more they need:
1395/25 = 55.8
This means that they need to sell at least 56 golf balls to meet the target.
Now to the Percussion Club...
Do the same thing again:
2400 - 1314 = $1086 to go
1086/18.25 = 59.51
So the percussion club needs to sell at lest 60 more tubs of popcorn to reach their target.
Hope this helps!! :)
