They must sell, 30 cups of lemonade. How I got my answer.
Since it cost $1.20 to start, and a cup of lemonade cost $0.6 to make and there selling them at $0.10 each. So we know they are making a $0.4 profit off of each cup of lemonade. We now have to multiply 4×30=120.
I hope this helps!
Answer:
The probability that two of them
die is 0.257
Step-by-step explanation:
From the question, we have that the mortality rate is 0.1
So the probability that they will survive is 1-0.1 = 0.9
Now, we want to check that two will die
We are going you use the Bernoulli approximation of the Binomial theorem as follows
= nCr * p^n * q^(n-r)
where n = 16
r = 2
P = 0.1
q = 0.9
Substituting these values;
14 C 2 * 0.1^2 * 0.9^12
= 0.257
False. Anything times 0.8 except 0, is 0.8 or more.
Answer:
x+2y=- 7
x-2y =9
Step-by-step explanation:
Solving Steps
2x+4y=-14
x-2y=9
Divide both sides
(2x+4y) ÷2=-14=2
{x-2y=9
Remove the parentheses
Divide
2x÷2+4y÷2=-7
x-2y =9
Divide
Solution
x+2y=- 7
x-2y =9
Answer:
6.279
Step-by-step explanation:
69% of 9.1
= 69/100 × 9.1
= 0.69 × 9.1
= 6.279
