Five pieces can be selected in 1287 ways

Step-by-step explanation:

When the selection has to be made without considering the order of selection, combinations are used.

The formula for combination is:

$C(n,r) = \frac{n!}{r!(n-r)!}$

Here

Total candies = n = 13

Candies to be selected = r = 5

Putting the values in the formula

$C(13,5) = \frac{13!}{5!(13-5)!}\\=\frac{13!}{5!8!}\\=1287\ ways$

Five pieces can be selected in 1287 ways

<h3>Emilo is more than half way done with his run during his water break</h3>

<em><u>Solution:</u></em>

Given that,

During practice, he has to run 40 laps around the track

To find: Is he more or less than halfway done with his run during his water break

From given,

Half way of his run = $40 \div 2 = 20$

After 26 laps, Emilio stops for water

$26 > 20$

Therefore, 26 is greater than 20

Thus, Emilo is more than half way done with his run during his water break

Which expression is equivalent to (m^5n/pq^2)^4

tatuchka [14]

$\left( \cfrac{m^5n}{pq^2}\right)^4 = \cfrac{(m^5n)^4}{(pq^2)^4}= \cfrac{m^{20}n^4}{p^4q^8}$

Answer:

The value of n = 12

Step-by-step explanation:

Given the points

(-4, n)

(2, 4n)

The slope formula

m = y₂-y₁ / x₂ - x₁

$\left(x_1,\:y_1\right)=\left(-4,\:n\right),\:\left(x_2,\:y_2\right)=\left(2,\:4n\right)$

$m=\frac{4n-n}{2-\left(-4\right)}$

$m=\frac{n}{2}$

Given that the slope = m = 6

Thus, substituting the value

6 = n/2

n = 6 × 2

= 12

Thus, the value of n = 12
