xYou volunteer to help drive children at a charity event to the zoo, but you can fit only 6 of the 16 children present in your

brilliants [131]

There are 8008 groups in total, in other to drive the children

<h3>How to determine the number of groups?</h3>

From the question, we have

Total number of children, n = 16
Numbers to children at once, r = 6

The number of group of children that could be carried at once is calculated using the following combination formula

Total = ⁿCᵣ

Where

n = 16 and r = 6

Substitute the known values in the above equation

Total = ¹⁶C₆

Apply the combination formula

ⁿCᵣ = n!/(n - r)!r!

So, we have

Total = 16!/10!6!

Evaluate

Total = 8008

Hence, the number of groups is 8008

the annual rate of inflation is given by the formula I = (p2/p1)^1/n - 1, where p1 is the initial price of an item and p2 is the

aleksklad [387]

Answer:

<h2>The value of $n$ is 31 years.</h2>

Step-by-step explanation:

The given equation is formed by different variables, where $n$ indicates the period of time in years where the rate of inflation is calculated.

In this case, we have a period from 1980 to 2011. The difference between these years would be the period of time used to find the inflation rate.

$2011-1980=31$

Therefore, the value of $n$ is 31 years.

Which of the following is a reasonable estimated answer to the following problem?

bulgar [2K]

$989,867 \approx 1,000,000$
$999 \approx 1000$

$\implies \frac{989,867}{999} \approx \frac{1,000,000}{1000}$
$\frac{1,000,000}{1000} = 1000$

So the answer is approximately 1000.

-0.38 (8 repeating) written as a fraction is _____.

natulia [17]

Answer:

$\frac{7}{18}$

Step-by-step explanation:

We first let 0.38 (8 being repeated) be T.

Since z is recurring in 1 decimal places, we multiply it by 10. 10z = 3.88

Next, we subtract them. 10 r T 3.88 0.38 9x 3.5

Lastly, we divide both sides by 9 to get IC as a fraction. 3.5 T 9 35 90 7 18
