Answer:
Step-by-step explanation:
Parts of the question are missing.
y = a(x-h)² + k is a vertical parabola.
If a is positive, the parabola opens upwards.
If a is negative, the parabola opens downwards.
The vertex is at (h, k)

Answer:
Step-by-step explanation:
There are
2 yellow
3 magenta
5 blue
marbles in the bag.
So total of 2 + 3 + 5 = 10 marbles
We have to multiply the probability of yellow on first pick by the probability of yellow on second pick (WITHOUT REPLACEMENT).
We denote P(Y1) as probability of yellow on first draw &
P(Y2) as probability of yellow on second draw
Thus,
P(Y1) = 2/10 = 1/5 [since 2 yellow and 10 total marbles]
Now,
P(Y2) = 1/9 [since now 1 yellow is taken out and NOT replaced, so we have 1 yellow remaining and total 9 marbles]
Now, we multiply:
P(Y1) * P(Y2) = 1/5 * 1/9 = 1/45
The probability is
Answer:
C) y=-1/4x
Explanation:
Part 1
Add up the values in the table: 90+36+54+45+63+72 = 360
This means 360 total drinks were sold. Of that total, 54 were medium regular.
The percentage of medium regular is 54/360 = 0.15 = 15%
Apply this percentage to the 640 customers he plans to sell to
15% of 640 = 0.15*640 = 96
<h3>Answer: 96</h3>
============================================
Part 2
It sounds like your teacher wants you to find the probability of picking pink lemonade. The table says that 36 small, 45 medium, and 72 large pink lemonades were sold. That means 36+45+72 = 153 pink lemonades were sold out of the 360 total
153/360 = 0.425
Then go through each answer choice to note that 17/40 = 0.425 as well
Therefore, 153/360 = 17/40
Answer: 17/40
