14.4

Step-by-step explanation:

Divide 18 miles by 5 hours to tell us how many miles she can do in 1 hour.

Multiply the answer by 4 to tell us how many miles in 4 hours.

(18/5) * 4 = 14.4 Miles

Answer:

14.4 miles

Step-by-step explanation:

To answer this question you first need to find out what Amanda can jog in 1 hour. I can do this by dividing by 5, since the question tells me that she jogs 18 miles in 5 hours. So, I do 18 divided by 5, which gives me 3.6. I now know that in one hour, she can jog 3.6 miles.

The next step is to multiply by 4, because I want to know what she can do in 4 hours. So, I do 3.6 multiplied by 4, which gives me 14.4. I now know she can jog 14.4 miles in 4 hours, which is my final answer,

For one toss of a certain coin, the probability that the outcome is heads is 0.6. If this coin is tossed 5 times, which of the f

pishuonlain [190]

Answer:

The probability is 0.33696

Step-by-step explanation:

The probability that the outcome will be heads x times is calculated using the following equation:

$P(x) = nCx*p^{x} *(1-p)^{n-x}$

nCx is calculated as:

$nCx=\frac{n!}{x!(n-x)!}$

This apply for variables that follows a binomial distribution. In which we have n independent and identical events with two possibles results: success and fail with a probability p and 1-p respectively.

So, In this case, n is equal to 5, and p is equal to 0.6 because we are going to call success the event in which the outcome of the coin is head.

Then, the probability that the outcome will be heads at least 4 times is calculated as:

P = P(4) + P(5)

Where P(4) is:

$P(4) = 5C4*0.6^{4} *(1-0.6)^{5-4}$

P(4)=0.2592

And P(5) is:

$P(5) = 5C5*0.6^{5} *(1-0.6)^{5-5}$

P(4)=0.07776

Finally, the probability is:

P = 0.2592 + 0.07776

P = 0.33696

I believe you did it correctly but over the wrong line. You were supposed to do it over line M and it looks like you did it over the X-axis.
