30% is equal to 0.3 (found by dividing the percentage by 100). Then we multiply the cost of dinner, $85, by 0.3 to find an answer of $25.50.
Answer: $25.50
The probability that an interaction lasts longer than 4 minutes is 0.0062.
<h3>What is probability theory?</h3>
probability theory in mathematics focus on the analysis of random phenomena and this theory let us know that the outcome of a random event cannot be determined before it occurs.
z = (4 - 3)/.4
z = 1/.4
z = 2.5
0.0062
Hence The probability that an interaction lasts longer than 4 minutes is 0.0062.

Answer:
Tan(x) = 1/
We know that Tan 30 = 1/
Therefore, x = 30 degrees

Answer:
Step-by-step explanation:
8x - 20.....factor a 4 out
4(2x - 5) <=== this one is correct...not 100% sure who wrote it
8x - 20...factor out a 2
2(4x - 10) <==== this is correct
8x - 20....factor out a -2
-2(-4x + 10) <==== this is correct
8x - 20....factor out a -4
-4(-2x + 5).....nobody did this one......but somebody tried....that person didn't factor correctly
