Answer:

x = 20°

y = 70°

Step-by-step explanation:

the angle adjacent to the 40° angle must be 140° because the two angles form a straight line (which contains 180°)

in the isosceles triangle with the 'x', that means the other two angles must be equal and are (180-140) ÷ 2, which equals 20°

to find 'y', consider the larger right triangle with angles of 90° and 20°; angle y must equal 180 - (90 + 20) = 70°

$\frac{2p}{9}+\frac{5p}{18}-\frac{5}{6}=\frac{2}{3}+\frac{p}{12}+\frac{1}{6}\ \ \ |Multiply\ by\ 36\\\\
4*2p+2*5p-5*6=12*2+3*p+6*1\\\\
8p+10p-30=24+3p+6\\\\
18p-30=3p+30\ \ \ |Subtract\ 3p\\\\
15p-30=30\ \ \ |Add\ 30\\\\
15p=60\ \ \ |Divide\ by\ 15\\\\
\boxed{p=4}$

What is meant by the term outlier? What should you do with an outlier?

saul85 [17]

Outliers are data that are in a very far distance from other values in a set of data

Once an outlier is detected in a set of data, we can do the following to them:

Discard the outlier
Change the value of the outlier with another value within close range
Consider the distribution given

We may have a set of data where some of the values are far in distance from the majority of the data. The set of such data are known as an outlier.

For example, give the set of data;

2, 4, 7, 45, 8

45 can be considered as an outlier since the distance of data to all other data is large.

Once an outlier is detected in a set of data, we can do the following to them:

Discard the outlier
Change the value of the outlier with another value within close range
Consider the distribution given

A political action committee is interested in the proportion of all registered voters who will vote "Yes" on a measure to expand

kirza4 [7]

Answer: parameter: The proportion of registered voters who will vote Yes on the measure.

Sample: The 1000 registered voters who participated in the study.

Statistic: The proportion of the 1000 registered voters that were surveyed who will vote Yes on the measure.

Variable: Yes or No for each registered voter

Population: All registered voters in the US

Data: The list of Yes and No answers that were given by the 1000 participants in the study.

Step-by-step explanation:

Definitions of the given terms:

Population: Large groups of individuals having similar characteristics as per the researcher's point of view.

Sample: It is a subset of the population used to represent it.
Parameter: Measure of particular characteristics in the population.
Statistic: Measure of particular characteristics in the sample.
Variable: Characteristics that vary.
Data: A collected information facts and statistics.

Hence, by using the above definitions, we have

Parameter: The proportion of registered voters who will vote Yes on the measure.
Sample: The 1000 registered voters who participated in the study.
Statistic: The proportion of the 1000 registered voters that were surveyed who will vote Yes on the measure.
Variable: Yes or No for each registered voter.
Population: All registered voters in the US.
Data: The list of Yes and No answers that were given by the 1000 participants in the study.
