Answer:
fg(-2)=f(5×-2+4)=f(-6)=8-10×-6=8+60=68
Answer:
180 = 90 + 52+ a
38 =a
Step-by-step explanation:
The sum of the angles of a triangle add to 180 degrees
180 = 90 + 52+ a
Combine like terms
180 = 142+a
Subtract 142 from each side
180 -142 = 142+ a -142
38 = a

<h3>What is the margin of error?</h3>
The margin of error is a statistic that expresses how much random sampling error there is in a survey's results. The wider the margin of error, the less confident one should be that a poll result reflects the outcome of a population-wide survey.
The random sample of 2500 sports fans, out of which 61% prefer basketball over soccer, therefore, we can write n=2500 and p=0.61. Thus, the margin of error can be written as,

Hence, the Margin of error in this survey is 1%.
