Kilo typed 1,125 words in 15 minutes let w represent the number of words typed each minute If Lolo typed the same number of word
Alborosie

Answer:

She type <u>75 words</u> in 1 minute.

Step-by-step explanation:

Given:

Lolo typed 1,125 words in 15 minutes.

Let w represent the number of words typed each minute.

Now, to find the number of words she type in 1 minute if Lolo typed the same number of words each minute.

So, we solve it by using cross multiplication method:

<u><em>As 1125 words is equivalent to 15 minutes.</em></u>

<u><em>Thus, w number of words equivalent to 1 minutes</em></u>.

\frac{1125}{15} =\frac{w}{1}

By cross multiplying we get:

⇒ 1125=15w

<em>Dividing both sides by 15 we get:</em>

⇒ 75=w

⇒ w=75.

Therefore, she type 75 words in 1 minute.

n studying the sampling distribution of the mean, you were asked to list all the different possible samples from a small populat
Mashutka [201]

The Total outcome with replacement will be given by ,3² = 9, the mean of the samples will be  2 , 4.5 , 3 , 7 , 4

<h3>What is Mean ?</h3>

Mean predicts the central tendency of a data set , It is determined by the ratio of sum of all the numbers to the total numbers in the data set.

On the basis of given data

The number given is 2,4,7

Size of the sample = 2 with replacement

The Total outcome with replacement will be given by

3² = 9

Possible outcome can be

2,2   2,4   2,7   4,4  4,2  4,7  7,7  7,2  7,4

The sample mean can be calculated as

(a+b)/2

(2+2)/2 = 2

similarly the mean of the samples will be  2 , 4.5 , 3 , 7 , 4

If you plotted these elevations on a vertical number
Vlad [161]

Answer:

The correct option is C

C) Hungary

Step-by-step explanation:

Suppose we draw a vertical number line such that it shows elevations of different countries. For y=0,  we get India. As all the rest of the values, expect Hungary, are given negative values, hence all the value will lie below India in the numbers line. The only country that lies above India in the number line is Hungary as only it has a positive number for the elevation. So the lowest elevation above 0 will be shown of Hungary which is 78.
