givi [52]

Answer:

Option B is correct, i.e. The amount of water originally in Wilson's can was 2.5 gallons.

Step-by-step explanation:

Given is the graph of Amount of water (in gallons) v/s Time (in seconds).

It is a linear graph whose general equation is given as follows:-

y=mx+b.

Where y = Amount of water, x = Time, m = slope, b = y-intercept (when time is zero).

Finding slope of line, m = (2.3 - 2.5)/(1 - 0) = -0.2 gallons per second.

Finding y-intercept of line, b = 2.5 gallons (at t=0).

Hence, option B is correct, i.e. The amount of water originally in Wilson's can was 2.5 gallons.

We draw 2 cards from a deck of 52 cards. what is the probability that both are queens?
solniwko [45]
Use combination
There are 4 queen cards in a deck of 52 cards
Probability = 4C2 / 52C2

I calculate 4C2 first
4C2 = 4! / (2! 2!)
4C2 = (4 × 3 × 2 × 1) / (2 × 1 × 2 × 1)
4C2 = 6

Then I calculate 52C2
52C2 = 52! / (50! 2!)
52C2 = (52 × 51)/2
52C2 = 1.326

Hence, the probability is
Probability = 4C2 / 52C2
Probability = 6/1,326
Probability = 1/221
