Given the measure of three angles in a quadrilateral, find the measure of the fourth angle.1. 40 degree , 120 degree , 100 degre

Veronika [31]

Recall that the interior angles of a quadrilateral add up to 360 degrees.

1) Let x be the measure of the missing angle, then we can set the following equation:

$40^{\circ}+120^{\circ}+100^{\circ}+x=360^{\circ}.$

Solving for x we get:

$\begin{gathered} 260^{\circ}+x=360^{\circ}, \\ x=100^{\circ}\text{.} \end{gathered}$

2) Let y be the measure of the missing angle, then we can set the following equation:

$73^{\circ}+107^{\circ}+122^{\circ}+y=360^{\circ}\text{.}$

Solving for y we get:

$\begin{gathered} 302^{\circ}+y=360^{\circ}, \\ y=58^{\circ}\text{.} \end{gathered}$

Answer:

1) 100 degrees.

2) 58 degrees.

A teacher wants to calculate a class average on the last test. One student made a significantly lower score than the rest of the

BigorU [14]

The answer is C. You would use MEAN because it gives you the average although it doesn't always have to be a whole number. Therefore despite that one student performing badly won't affect the rest of the class.
Again hope this helps : )

Suppose U.S. consumers 21 years and older consumed 26.8 gallons of beer and cider per person during 2017. A distributor in Milwa

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 .
