Answer:

20x² + 25 x + 8

Step-by-step explanation:

f(x) = 4x² + 5x + 3

g(x) = 5x -7

Then:

g(f(x)) = 5(4x² + 5x + 3) -7

g(f(x)) = 20x² + 25x + 15 - 7

g(f(x)) = 20x² + 25x + 8

Help any one? Pls you’ve been so helpful pls don’t let it end

You missed one final step, no worries! When finding the percent off, subtract the value you got after dividing the price after discount by the initial price from 100.
So: 100 - 65 = 35

35% off

Hope this helps!

A blind taste test will be conducted with 9 volunteers to determine whether people can taste a difference between bottled water

Aloiza [94]

Answer:

The answer is $\frac{1}{256}$

Step-by-step explanation:

If we assume that people cannot taste a difference between bottled water, then the probability of identifying tap water is 0.5

Thus, P(identify tap water)=0.5

The probability that at least 8 of the 9 people identify the tap water correctly is the sum of the probabilities

8 of 9 people identified correctly or
9 of 9 people identified correctly

Since P(identify tap water)=0.5 each probabilities are the same and equal to

$0.5^9$ = $\frac{1}{512}$

So we have $2*\frac{1}{512}$ = $\frac{1}{256}$
