Answer:

Step-by-step explanation:

common ratio=18/-3=-108/18=-6, a=-3

sn=a(r^n-1)(r-1)

sn=-3((-6)^n-1)(-6-1)

sn=-3(-6)^8-1)/(-7)

s8=-3(1679615)/(-7)

s8=719836

In the equation z/6 =

Nikitich [7]

Hi there!

»»————-　★　————-««

I believe your answer is:

"Isolate the variable using inverse operations."

»»————-　★　————-««

Here’s why:

To solve for a variable, we would have to isolate it on one side.

To isolate it, we would use inverse operations on both sides on the equation until the variable is isolated.

There are no like terms in the given equation.

⸻⸻⸻⸻

$\boxed{\text{Solving for 'z'...}}\\\\\frac{z}{6} = 36\\-------------\\\rightarrow (\frac{z}{6})6 = (36)6\\\\\rightarrow \boxed{z = 216}$

Hope this helps you. I apologize if it’s incorrect.

The total frequency is 20+120+40+20 = 200. This means they ran the experiment 200 times. The probability distribution is calculated by the satisfactory number of outcomes (frequency) divided by the total number of experiments/outcomes (total frequency):

$\begin{array}{c|c||lc}\underline{x}&\underline{f}&\underline{f\div 200}&\underline{\text{Probability Distribution}}\\1&20&20\div200=&0.10\\2&120&120\div 200=&0.60\\3&40&40\div 200=&0.20\\4&20&20\div 200=&0.10\end{array}\right]$

Your choir has 300 tickets to sell. You are responsible for distributing 10 tickets to each choir member to sell. A - Write an e

Goshia [24]

Answer:

Remaining tickets left to distribute, A = (300 - 10m)

Step-by-step explanation:

a) Let the number of choir members be m

Let the number of tickets remaining after the distribution be A

Each choir member is to get 10 tickets each.

Number of tickets to be given to the members = 10m

original number of tickets = 300

So, number of tickets remaining after distribution, A = 300 - 10m (provided that m ≤ 30)

b) The independent variable in this expression is m (the number of choir members)

And the dependent variable is A (the number of tickets left after the distribution which depends on the number of choir members, m)

Hope this Helps!!!
