Answer:
20 1/4
Step-by-step explanation:
We can turn the fractions improper to solve
4 1/2= 9/2, 9/2 is the improper fraction so now we multiply
9/2 x 9/2=81/4, 81/4 is improper and isn't one of the choices so we can change it into a mixed fraction.
81/4 is equal to 20 1/4

The sum of angle measures inside a triangle equals 180°. Subtract 180-135 to find the measure of angle a. 180-135=45. Then add 45 and 58 to get 103. Then you subtract 103 from 180 to get an answer of 77.
Answer:
The sampling error = 0.06
Step-by-step explanation:
From the given information:
Let represent
to be the population proportion = 0.4
The sample proportion be P = 0.46 &
The sample size be n = 100
The population standard duration can be expressed by the relation:
Population standard duration 



The sample proportion = 0.46
Then the sampling error = P -
The sampling error = 0.46 - 0.4
The sampling error = 0.06
