A^2 + b^2 = c^2
16^2 + 12^2 = c^2
256 + 144 = c^2
400 = c^2
sqrt 400 = c
20 = c <== the ladder is 20 ft long
Answer:
Unlikely, the probability is close to 0
Step-by-step explanation:
Given

Required
Determine the likelihood
The given probability, 0.15 is close to 0. This implies that the event is unlikely.
From the list of given options, option C answers the question
10(1/2x + 5) = 7
That's the way to write the description of that equation. Good luck!!
X= sales tax %
Step 1:
$240 * sales tax %= $12
240 * x= 12
240x=12
Divide both sides by 240
x= 0.05 (decimal of the %)
Convert to %:
Multiply decimal by 100 (or move decimal to the right two decimal places
=0.05 x 100
=5 %
The sales tax is 5%.
Hope this helps! :)
114
1) Gathering the data
The mean is calculated by adding all the numbers and divided by the number of observations in this case 5.
So, Laura needs to score 114 to get at least 94 as an average.
