Answer:
Generally, the data is arranged from smallest to largest: First quartile: the lowest 25% of numbers. Second quartile: between 25.1% and 50% (up to the median) Third quartile: 51% to 75% (above the median)
Step-by-step explanation:
Answer:
Candle B: 36 minutes
Candle C: 12 minutes
Step-by-step explanation:
Since Candle A burns for 72, and Candle B burns twice as fast, we can divide the 72 by 2 in order to get the time it burns. We will then see that Candle B burns for 36 minutes.
Candle C burns 3 times as fast as candle B so we can divide the 36 minutes it takes for candle B to burn by 3 to get how long it takes Candle C to burn. We then see that it takes 12 minutes for candle C to burn.
Hope this helps!
Answer:
y = 1/4(x + 1)^2 + 3.
Step-by-step explanation:
The general form is (x - h)^2 = 4p(y - k) where the focus is (h, k+p) and the directrix is y = k-p
So we have h = -1
k + p = 4
k - p = 2 Adding:
2k = 6 so k = 3 and p = 1.
Therefore:
(x + 1)^2 = 4(y - 3)
4y = (x + 1)^2 + 12
y = 1/4(x + 1)^2 + 3.
