How do you solve fire x.
makkiz [27]

Answer:

x = 10

Step-by-step explanation:

Sum of all the angle of triangle = 180

71 + 50 + 6x - 1 = 180

71 + 50 -1 + 6x = 180

    120  + 6x   = 180

            6x = 180 - 120

           6x = 60

             x = 60/6

x = 10

Kruka [31]

Answer:

d) Conclude that the population mean annual consumption of beer and cider in Milwaukee is greater than 26.8 gallons and hence higher than throughout the United States.

Step-by-step explanation:

We have a hypothesis test about the true mean consumptionof beer and cider for U.S. 21+ years-old consumers with the following null and alternative hypothesis:

H_0: \mu=26.8\\\\H_a:\mu> 26.8

The result of the test is to reject the null hypothesis.

This means that there is evidence to support the claim that beer and cider consumption was higher than the national average in Milwaukee in 2017 .
