From 1-5 is four hours

4 *60 =240 rotations

If g(x) and f(x) are inverse functions, which graph represents g(x)?

34kurt

When g(x) and f(x) are inverse functions, the graph that represents g(x) is the second graph.

<h3>How to explain the graph?</h3>

It should be noted that the first graph shows the radical expression where, f(x) = ✓x.

In order to find the inverse, we need to replace f(x) with y and switch the x. This will be:

x = ✓y

(✓y)² = x².

y = g(x) = x²

Therefore, the graph that shows the exponential growth is the second graph.

Jeff makes fruit punch using 1 quart of orange juice 2 pints of pineapple juice 8 cups of tropical punch and 8 pints of ginger a

Amiraneli [1.4K]

Answer:

2 gallons

Step-by-step explanation:

So say we make everything into cups. We know there is 4 cups in a quart and 2 cups in a pint. So if we do the math you are really adding

4 cups + 4 cups + 8 cups + 16 cups

So that would be 32 cups.

We also know there is 16 cups in a gallon. Since we know that then we can do

32 cups ÷ 16 cups

That would be 2 gallons!

Hope this helps!

Brayden tosses a coin 500 times. Of those 500 times, he observes heads a total of 416 times. Calculations show that the probabil

elena-14-01-66 [18.8K]

Answer: The probability of this ocurring by chance is less than 0.01.

The meaning of the significance level is that it tells that there is difference of 1% level when there is no actual difference.

Step-by-step explanation:

Since we have given that

Number of times a coin tossed = 500

Number of times head occurs = 416

So, our Z-score would be

$Z_\alpha =\dfrac{416}{500}=0.832$

So, At significance level of 0.01, p-value of Z-score is .202704.

and p-value < 0.01, i.e. 0.202704<0.832.

Hence, the probability of this ocurring by chance is less than 0.01.

The meaning of the significance level is that it tells that there is difference of 1% level when there is no actual difference.

If five times the smaller of two numbers is subtracted from twice the larger the result is 16 if the larger is increased by thre

Rudiy27

Answer:

Smaller Number = 10

Larger Number = 33

Step-by-step explanation:

Let the smaller number be "x" and the larger number be "y"

5 TIMES smaller is SUBTRACTED from TWICE larger, the result is 16, we can write:

2y - 5x = 16

and

Larger increased by 3 TIMES SMALLER, result is 63, so we can write:

y + 3x = 63

We can write this in terms of x, as:

y = 63 - 3x

Now we put this in equation 1 and solve for x first:

2y - 5x = 16

$2(63 - 3x) - 5x = 16\\126-6x-5x=16\\11x=110\\x=10$

Now,

y = 63 - 3x

y = 63 - 3(10)

y = 63 - 30

y = 33

Smaller Number = 10

Larger Number = 33
