Median: is the number in the middle when the set data set is in order
mode: it the number that occurs the most in the set
range:difference between the smallest and largest number
IQR: interquartile range is a measure of a data set separated into quartiles

Answer:

Median - it represents the middle number in the data set.

Range - you have to find the lowest value and the highest value and get the final answer, same with the interquartile range, you just have to find the lower quartile and upper quartile and subtract it and you get the final answer in the following data set.

20.) Which inequality represents the solution on the graph?*<br><br>

VMariaS [17]

Answer:

Option 2

Step-by-step explanation:

You can see that the graph of the inequality is x <= -3, so you want to find why inequality matches that. Solve each one:

1

. $3x \geq -9\\x \geq -3$

doesn't match

2.

$-7x\geq 21\\x\leq -3$

Does match, so this is the answer.

Heights for women are bell-shaped with a mean of 65 inches and standard deviation of 2.5 inches. If a random sample of 16 women

loris [4]

Answer:

μ= 65 inches; σ= 0.625 inch

Step-by-step explanation:

The Central Limit Theorem estabilishes that, for a normally distributed(bell-shaped) random variable X, with mean $\mu$ and standard deviation $\sigma$ , the sampling distribution of the sample means with size n can be approximated to a normal distribution with mean $\mu$ and standard deviation $s = \frac{\sigma}{\sqrt{n}}$ .

For a skewed variable, the Central Limit Theorem can also be applied, as long as n is at least 30.

In this problem, we have that:

$\mu = 65, \sigma = 2.5$

By the central limit theorem, the sample of 16 will have:

$\mu = 65, \sigma = \frac{2.5}{\sqrt{16}} = 0.625$

So the correct answer is:

μ= 65 inches; σ= 0.625 inch

How do I make a linear function, what is a linear function?

mixer [17]

Answer:

I have uploaded a picture so you could understand it a little more.

A linear function is when there is a table that gives numbers that represent a function, as shown in the picture.

In the Image, there is a table with a x and y column. And in both columns, there are numbers.

This is what the table looks like in the picture:

<u> x y </u>

0 4 The key is y = 2x + 4

1 6 <------ lets grab the number 1 in the x column and lets

2 8 multiply it by two. Now add four to it, and we will

3 10 have the number 6 in the y column.

4 12

I hope I helped you! God bless :-)

ANSWER PLEASE I WILL MARK AS BRAINLIEST

ICE Princess25 [194]

Answer:

162 mL

Step-by-step explanation:

1.Convert all volumes to millilitres

(a) Chlorpheniramine

V = 100 mL

(b) Lidocaine

$V = \text{2 fl oz} \times \dfrac{\text{29.57 mL}}{\text{1 fl oz}} = \textbf{59 mL}$

(c) Banana flavouring

$V = \dfrac{1}{2}\text{ tsp} \times \dfrac{\text{4.928 mL}}{\text{1 tsp}} = \textbf{2.5 mL}$

2.Calculate the total volume

Chlorpheniramine = 100 mL

Lidocaine = 59

Banana flavouring = <u> 2.5 </u>

TOTAL = 162 mL

What is the constant of variation for the inverse variation? xy = 8

Advocard [28]

Answer:

8

Step-by-step explanation:

The constant of variation is the constant in the equation: 8.

___

The equation can be rewritten to be

y = 8/x

Compared to the generic equation for inverse variation, ...

y = k/x

we see that the constant of variation (k) is the constant in the given equation, 8.
