Answer:

option C

Step-by-step explanation:

set A= {5, 10, 15, 20…}

5, 10, 15, 20…  are the multiples of 5

Here all the numbers are positive and all the numbers are rounded numbers

5, 10, 15, 20… are the natural numbers and they are represented by N

So set A is x such that x is a natural number and x is a multiples of 5

Its option C

To shift the graph of an equation a certain number of units _____, you need to subtract that number from the functions equation
FromTheMoon [43]

Answer:

The correct option is A) Down.

Step-by-step explanation:

A function can be shift vertically up or down by adding some positive or negative constant.

For example:

Consider the figure 1:

The function g(x)=f(x)+k shifted up by <em>k</em> unit. (where <em>k</em> is 1 unit)

Now consider the figure 2:

The function g(x)=f(x)-k shifted down by <em>k</em> unit. (where <em>k</em> is 1 unit)

Which means to shift the graph of an equation certain number of units up, we need to add that number from the functions equation.

Similarly, to shift the graph of an equation certain number of units down, we need to subtract that number from the functions equation.

Therefore, the correct option is A) Down.

Identify the type I error and the type II error that corresponds to the given hypothesis. The proportion of people who write wit
SCORPION-xisa [38]

Answer:

Type I error is to Reject the claim that the proportion of people who write with their left hand is 0.29 when the proportion is actually 0.29.

Type II error is Fail to reject the claim that the proportion of people who write with their left hand is 0.29 when the proportion is different from 0.29.

Step-by-step explanation:

We are given the following hypothesis below;

Let p = <u><em>proportion of people who write with their left hand</em></u>

So, Null Hypothesis, H_0 : p = 0.22     {means that the proportion of people who write with their left hand is equal to 0.22}

Alternate Hypothesis, H_A : p \neq 0.22      {means that the proportion of people who write with their left hand is different from 0.22}

Now, Type I error states that we conclude that the null hypothesis is rejected when in fact the null hypothesis was actually true. Or in other words, it is the probability of rejecting a true hypothesis.

So, in our question; Type I error is to Reject the claim that the proportion of people who write with their left hand is 0.29 when the proportion is actually 0.29.

Type II error states that we conclude that the null hypothesis is accepted when in fact the null hypothesis was actually false. Or in other words, it is the probability of accepting a false hypothesis.

So, in our question; Type II error is Fail to reject the claim that the proportion of people who write with their left hand is 0.29 when the proportion is different from 0.29.
