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 $2*\frac{1}{512}$ = $\frac{1}{256}$

A hot air balloon went from an elevation of 6,678 feet to an elevation of 3,438 feet in 48 minutes. What was its rate of descent

gregori [183]

Answer:

The rate of descent is $-67.5\frac{feet}{minute}$

Step-by-step explanation:

we know that

The formula to calculate the rate or slope between two points is equal to

$m=\frac{y2-y1}{x2-x1}$

Let

x------> the time in minutes

y----> the elevation in feet

we have

$A(0,6,678)\ B(48,3,438)$

Substitute the values

$m=\frac{3,438-6,678}{48-0}$

$m=\frac{-3,240}{48}$

$m=-67.5\frac{feet}{minute}$

How many ink cartridges can you buy with 150 dollars if one cartridge costs 15 dollars ?

musickatia [10]

Answer:

Step-by-step explanation:

Very easy equation if you know how to do it. All you need to do is divide your total amount of something (in this case "150" as that's our amount of "money we're given") by whatever the price or amount is. (In this case 15. Each cartridge costs $15. I'm not amazing at explaining things like this.. Sorry about that. If you have any questions about this feel free to let me know!)

So to put it "all together":

150 ÷ 15 = 10.

10 is your answer.

Hope this helps and have a nice day!
