what is the purpose of using measures of variability?

Answers

Answer 1
Variability describes how far apart data points lie from each other and from the center of distribution. Along with measures of central tendency, measure of variability give you descriptive statistics that summarize your data. Variability is also referred to as spread, scatter or dispersion.


Answer: it gives you descriptive statistics that summarize your data.

The difference between a number and −22 is equal to the number times 11.

Answers

Answer:

The equation looks like this x-(-22)=11x

The answer for the equation is x=11/5

Step-by-step explanation:

Difference between a number (x) and -22

Difference means subtract so x subtracted by -22

x-(-22)

Is equal to: which means you put a =

the number times 11

number is x so x times 11 is 11x

The equation looks like this:

x-(-22)=11x

simplify

x+22=11x

Move x to the other side:

22=10x

Divide 10 on both sides:

x=22/10

Due to the fact that no one can consume .04 of a tablet, we can round down this answer to 1. Even if we were told to round to the tens place, we would still be unable. Remember, 5 or above, give it a shove, 4 or below, let it go. This means that Mr. Jones should take C- 1 tablet per day.

Answers

Answer:

Cost of each pendant = $2.80

Step-by-step explanation:

Since we're given information regarding the total cost of beads, $13.20, and the total cost of beads and pendants for all 4 necklaces, $24.40:

Let b = beads

p = pendants

C = total cost of beads and pendants for all 4 necklaces.

b + p = C

$13.20 + p  = $24.40

$13.20 - $13.20 + p  = $24.40 - $13.20

p = $11.20 (This represents the total cost of 4 pendants).

To find out the cost of each pendant, divide $11.20 by 4:

$11.20 ÷ 4 = $2.80

Therefore, the cost of each pendant is $2.80.

Answer:

I'm 50% sure it's $7.52 though I may be wrong

The functions r and s are defined as follows.

To rent a certain meeting room, a college charges a reservation fee of $13 and an additional fee of $5 per hour. The chemistry club wants to spend less than
$43 on renting the room. What are the possible numbers of hours the chemistry club could rent the meeting room?
Use t for the number of hours.
Write your answer as an inequality solved for t.

Answers

Answer:

2 hours or lower

Step-by-step explanation:

$13 + $5t = fee

13 + 15t = 43 --> minus 13 on both sides

15t = 30 --> divide by 15 on both sides

t = 2

Answer: t=6

Explanation:

They want to spend less than $43, 43-13=30 and 30/5=6, Therefore they could have 6 hours max, if the initial reservation fee is $13 and and additional $5 per hour.

(a) I wanted to determine how much water my sprinkler was using, so I set out a bunch of empty cat food cans at various distances from the sprinkler and noted how high the water was in each can after one hour. My sprinkler reaches from 0 feet to 16 feet away from the sprinkler. The data are given in Table 1. The sprinkler distributes water in a circular pattern, so I assumed that points the same distance from the sprinkler received the same amounts of water. One way to use the data in Table 1 to estimate how many cubic feet of water my lawn got from my sprinkler in one hour is to write down an integral for the volume of water using the method of shells, and then use a right-endpoint Riemann sum to approximate this integral. Give your answer in decimal form rounded to the nearest cubic foot.
(b) My neighbor decided to collect the same data for her watering. Her sprinkler reaches from 0 feet to 21 feet away from the sprinkler, but she did not set out the cans at evenly spaced distances and so the calculation is a bit more complicated. The data are given in Table 2.Use the data in Table 2 to estimate how many cubic feet of water her lawn got from her sprinkler in one hour. Again, write down an integral for the volume of water using the method of shells, and then use a right-endpoint Riemann sum with subintervals of different lengths to approximate this integral. Give your answer in decimal form rounded to the nearest cubic foot.

Suppose that this number is accurate and that individuals predisposed to allergies are chosen at random and given allergy vaccinations.
a. Estimate the number of individuals in the random sample who do not find relief from their sinusitis by giving the mean of the relevant distribution (that is, the expectation of the relevant random variable).
