Based on the information given, it should be noted that the probability that the proportion of voters that will support the ballot measure will be greater than 0.50 is 0.0895.

<h3>How to calculate the probability.</h3>

From the information given, it was stated that a polling agency is investigating the voter support for a ballot measure in an upcoming city election and that the the population proportion of voters who would support the ballot measure in region a is 0. 47.

Based on the complete information, the probability that the proportion of voters in the sample of region A that will support the ballot measure will be greater than 0.50 will be given as P(Z > 1.3441).

It should be noted that when this value is looked in the table, it will give a value of 0.0895.

If point E(5, h) is on the line that contains A(0, 1) and B(−2, −1), what is the value of h?
nikdorinn [45]
First calculate the change in y over the change in x:

by - ay -1 - 1 -2
———— = ——— = —— = 1
bx - ax -2 - 0 -2


The slope is 1:

Second set up the equation in y = mx + b form (m is your slope!) ...

y = (1)x + b

... and plug in either point you have used (A or B)

A(0,1)

1 = (1)(0) + b
1 = b

Now you have your equation: y = 1x + 1

Your final step is to plug in point C to solve for your missing variable:

y = (1)(5) + 1
y = 6

the value of H therefore is 6

Which of the following random variables is geometric?
yawa3891 [41]

Answer:

b. The number of digits in a randomly selected row until a 3 is found.

Explanation:

A random variable often used in statistics and probability, is a variable that has its possible values as numerical outcomes of a random experiment or phenomenon. It is usually denoted by a capital letter, such as X.

In statistics and probability, random variables are either continuous or discrete.

1. A continuous random variable is a variable that has its possible values as an infinite value, meaning it cannot be counted.

2. A discrete random variable is a variable that has its possible values as a finite value, meaning it can be counted.

Also, any random variable that meets certain conditions defined in a research study.

Hence, an example of a geometric random variables is the number of digits in a randomly selected row until a 3 is found.

philly and boston were working on a project in carpentry class. they needed to cut 5 lengths of 234 feet from a board. how long
ss7ja [257]

or 5 lengths of 234 feet to be cut from a board, the board must have a length of at least 1170 feet.

Let x represent the total length of the board so as to allow for the cutting of 5 lengths.

Since each length needed to be cut is 234 feet, hence:

x = number of lengths × feet per board

x = 5 lengths × 234 feet

x = 1170 feet

Hence for 5 lengths of 234 feet to be cut from a board, the board must have a length of at least 1170 feet.

The best description of  Steffens' purpose in writing about government is:

  • <u>B. to describe corruption in city and state governments</u>

<u />

According to the quotation from Lincoln Steffen's The Shame of the Cities, we are told that the author feels that the shamelessness of the American people would cause the downfall of the "American pride".

As a result of this, the most likely purpose of writing this is to show the level of corruption which is prevalent in the city and state governments to spur the citizens to revolt against the corruption.

Therefore, the correct answer is option B
