Let 2_1/2 = 5/2.

Let t = time to fill 8 tires

(5/2)/8 = (5/2)/t

8(5/2) = (5/2)t

20 = (5/2)t

20 ÷ 5/2 = t

20 • 2/5 = t

8 seconds = t

Done.

What functions have real zeros at 1 and 4
Sunny_sXe [5.5K]

Answer:

y=a(x^2-5x+4)

Step-by-step explanation:

I mean there are a bunch of answers. to figure it out, you can use the formula where you have solved the zeroes in terms of x.

y=(x-1)(x-4)

y=x^2-5x+4

Now if you add any a value to this function, your function will stretch or compress accordingly

y=a(x^2-5x+4)

So there isn't a single correct answer, but if you're looking for a bunch, then just replace the a value with whatever value you want, you'll still get the same answer since they're all proportional to one another.

Answer:

Clearly, the probability of drawing a heart out of the deck is 13/52, or 1/4. The probability of drawing an even number as card #2 (∈{2,4,6,8,10}) for any suit is 20/51, except when the first card drawn is an even heart, then the probability of the second draw is 19/51.
