I already answered that question, here's the link: brainly.com/question/10534199.

But if you still want the explanation, here it is:

"So if we want to measure probability, you have to add, then divide, like this:

First 4+8+6, which gives us 18.

Then we see, that 6 is 1/3 of 18, so we conclude. The answer is 33.33%.

Hope this helped!

If f(x)f(x) is an exponential function where f(-1)=5f(−1)=5 and f(7)=32f(7)=32, then find the value of f(4)f(4), to the nearest
Whitepunk [10]

Using an exponential function, it is found that the value of the function when x = 4 is of f(4) = 15.95.

<h3>What is an exponential function?</h3>

It is modeled by:

y = ab^x

In which:

  • a is the initial value.
  • b is the rate of change, as a decimal.

In this problem, we have that f(-1)=5, hence:

5 = ab^{-1}

\frac{a}{b} = 5

a = 5b

We also have that f(7)=32, hence:

32 = ab^7

Since a = 5b:

5b^8 = 32

b = \sqrt[8]{\frac{32}{5}}

b = 1.2612.

a = 5b = 5 x 1.2612 = 6.306.

Hence the function is given by:

y = 6.306(1.2612)^x

Then, when x = 4, we have that:

y = 6.306(1.2612)^4 = 15.95

lord [1]

If one basket is selected at random, the probability that both are mangoes is; 1/10

<h3>How to find probabilities?</h3>

Contents of first basket;

3 mangoes

4 oranges

3 apples

Contents of second basket;

5 mangoes.

5 oranges.

5 apples.

Probability of mango in first basket is = 3/10

Probability of mango in second basket is = 5/15

Thus;

Probability that both are mangoes = (3/10) * (5/15)

Probability that both are mangoes = 1/10
