Answer:
9 burritos
Step-by-step explanation:
We can use ratios to solve
8 cups 12 cups
---------- = -----------------
6 burritos x burritos
Using cross products
8x = 6*12
8x = 72
Divide by 8
8x/8 =72/8
x = 9
9 burritos
The answer is 210 just multiply 420 by 7 cause theres 7 days is a week you get 2,940 minus from 3,150
Answer:
y = 5x2 + 10x - 15
We want this in format y = a(x-h)2 + k
where the vertex will be at (h,k)
y = 5(x2+2x) - 15
Complete the square on x2+2x
y = 5(x2+2x+1) - 15 - 5
We subtract 5 at the end because we are actually adding 5(1) = 5
so we need to remove it also to keep the total equal
y = 5(x+1)2 - 20
The vertex is at (-1,-20)
Answer:
65%
Step-by-step explanation:
No, the events "drank coffee" and "drank tea" are not mutually exclusive, as there are 10% of employees drank both coffee and tea.
If there are 50% drank coffee and 10% of them enjoy both, then there are 40% of the employees enjoy only coffee.
Similarly, there are 15% of employees who only enjoy tea.
Then the probability of selecting a person who only enjoy tea or coffee is
40% + 15% = 65%
