Answer:
5
Step-by-step explanation:
The probability of tails is 1/2, so the expected value is (1/2) (10) = 5.
X=7%
y=12%
x+y=20000
0.07x+0.12y=20000*0.19=3800
The correct answer is a (8^3) because you write out 8 being multiplied 3 times, which is the correct answer
Answer:
2x + 4y
$40
Step-by-step explanation:
Equation for x small balloons and y large balloons
2x + 4y
Total cost of 10 small balloons and 5 large balloons
x = 10, y = 5
2(10) + 4(5)
= 20 + 20
= $40
