Answer: The value of n is 5

Step-by-step explanation:

-Solve:

3^2 × 3^3 =3^n

-If two numbers with exponents are multiplying together, then the exponents would add up together:

3^5 = 3^n

-Simplify by the exponent:

243 = 3^n

-Take the logarithm both sides of the equation:

log(3^n)= log (243)

- Then, you divide both sides by log (3) :

n=\frac{log(243)}{log(3)}

- Use the change-of-base formula, which is \frac{log(a)}{log(b)} = log_{b}(a):

n = log_{3}(243)

n = 5

So, the value of n is 5.

The table shows the results for spinning the spinner 75 times. What is the relative frequency for the event​ "spin a 3​"?
Vadim26 [7]

Answer: 0.267

Step-by-step explanation:

The relative frequency is the number of times that we obtained a given outcome divided by the total numer of trials.

In this case we have 75 trials.

in 20 trials the outcome was a 3.

Then the relative frequency of the event "spin a 3" is:

p = 20/75 = 0.266... = 0.267

X = 10<br><br> x = 2<br><br> x = two divided by five.<br><br> x = 11
KengaRu [80]

Answer:

x = 10

Step-by-step explanation:

You can try the answers to see which works. (The first one does.)

Or, you can solve for the variable:

Divide by 75

... (1/5)^(x/5) = 3/75 = 1/25

Recognize that 25 = 5^2, so ...

... (1/5)^(x/5) = (1/5)^2

Equating exponents, you have

... x/5 = 2

... x = 10 . . . . . multiply by 5

_____

You can also start by taking logarithms:

... log(75) +(x/5)log(1/5) = log(3)

... (x/5)log(1/5) = log(3) -log(75) = log(3/75) = log(1/25) . . . . simplify the log

... x/5 = log(1/25)/log(1/5) = 2 . . . . . simplify (or evaluate) the log expression

... x = 10 . . . . . multiply by 5

_____

"Equating exponents" is essentially the same as taking logarithms.
