1/6
This is because the probability of pulling a red is 1/3. Multiply that by itself to find the chance of repeating.
The mean of the data is 15 all you gotta do is add all the number up and divide by the numbers added
#13:
s² = 144
√(s²) = √144
|s| = 12
s = -12 OR s = 12
--------------------
#15 (not sure what letter you used so I went with 'g')
(g-6)² = 25
√[(g-6)²] = √25
|g-6| = 5
g - 6 = -5 OR g - 6 = 5
g = 1 OR g = 11
Erika is working on solving the exponential equation 50^x = 17; The solution is x = 0.7242.
<h3>What is logarithm?</h3>
When you raise a number with an exponent, there comes a result.
Let's say you get
a^b = c
Then, you can write 'b' in terms of 'a' and 'c' using a logarithm as follows

'a' is called base of this log function. We say that 'b' is the logarithm of 'c' to base 'a'
Erika is working on solving the exponential equation 50^x = 17;
however, she is not quite sure where to start.
The equation is

By taking the log both sides

By using the base formula

So, 

x = 0.7242
