A 12.5% B 27.1% C 40.3% D 44.6%
Answers
Answer:
The probability that Kyle will pick a girl who likes football is 12.5%.
Step-by-step explanation:
The data provided is as follows:
Boys Girls Total
Basketball 10 8 18
Football 25 7 32
Soccer 9 19 28
Baseball 18 22 40
Total 62 56 118
Compute the probability that Kyle will pick a girl who likes football as follows:
[tex]P(F|G)=\frac{n(G\cap F)}{n(G)}[/tex]
[tex]=\frac{7}{56}\\\\=0.125\\\\=12.5\%[/tex]

Kiran's mother gets a restaurant bill for $25. She has a coupon for 15%. After the discount is applied, she adds 20% as a tip. What is the total after the discount and tip? (don't forget the $)
Answers
Answer:
$25.50
Step-by-step explanation:
So we have a 15% off coupon. We can multiply 25×.85 to find our new price.
Our total is now $21.25
Now to find the tip do $21.25 +(.2 × 21.25)
*The .2 is 20 percent of our discount price.*
We then get $25.50
A distrubutor wants to make 1,000 pounds of trail mix that is 8% raisins. He will use a mix that is 5% raisins and a mix that is 20% raisins. How many pounds of each should he use?
Answers
Answer:
He should use 800 pounds of trail mix 5% raisins and 200 pounds of trail mix 20% raisins
Step-by-step explanation:
System of Equations
Let's call
x = pounds of trail mix 5% raisins
y = pounds of trail mix 20% raisins
The distributor wants to make 1,000 pounds of trail mix, thus:
x + y = 1,000 [1]
The mix must be 8% raisings as a combination of x and y, thus:
5x + 20y = 8*1,000 = 8,000
Dividing by 5:
x + 4y = 1,600 [2]
Subtracting [2] and [1]:
4y - y = 1,600 - 1,000
Operating:
3y = 600
y = 200
From [1]
x = 1,000 - y = 1,000 - 200
x = 800
He should use 800 pounds of trail mix 5% raisins and 200 pounds of trail mix 20% raisins
Answer:
5% raisin mix: 800 lbs
20% raisin mix: 200 lbs
Step-by-step explanation:
Let number of 5% be x; and number of 20% be a.
x + y = 1000
5% · x + 20% · y = 8% of 1000 pounds
0.05x + 0.2y = 80
x = 1000 - y
0.05(1000 - y) + 0.2y = 80
50 - 0.05y + 0.2y = 80
0.15y = 30
y = 200
x = 1000 - y
x = 1000 - 200
x = 800

Ethan goes to a store an buys an item that costs xx dollars. He has a coupon for 5% off, and then a 9% tax is added to the discounted price. Write an expression in terms of xx that represents the total amount that Ethan paid at the register.
Answers
Answer:
Final Cost= 1.09(xx - .05xx)
Step-by-step explanation:
Since its 9% tax on the new price you would take the new price which would be 1.0 and add the .09 of tax. So its ×1.09 to get the tax.
The expression for the total cost is 1.09(xx-(0.05)xx).
What is total cost?The total cost is the amount calculated after any discount for an item and along with the tax incurred for an item to be purchased.
For the given situation,
Ethan buys an item that costs xx dollars.
He has discount coupon of 5% = 0.05
The tax percentage is 9% = 0.09
The discounted amount will get less from the cost price. So,
⇒ [tex]xx-(0.05)xx[/tex]
The tax amount for the item will get added to the final cost of an item. Thus the expression becomes,
⇒ [tex]1.09(xx-(0.05)xx)[/tex]
Hence we can conclude that the expression for the total cost is 1.09(xx-(0.05)xx).
