Using the relation between standard deviation and variance it is concluded that the standard deviation for the population for the given variance is 7.1

<h3>What is the relation between standard deviation and sample variance? </h3>

In statistics, the two most crucial metrics are variance and standard deviation. While the variance is a measurement of how data points vary from the mean, standard deviation is a measure of the distribution of statistical data.

The square root of the variance yields the standard deviation, i.e.

Standard deviation = \sqrt{variance

Given that sample, the variance is 49.7 and we have to calculate the standard deviation.

Standard deviation (σ) = \sqrt{variance

= \sqrt{49.7}

= 7.0498

=7.1

Hence, the standard deviation for the population for the given variance is 7.1

Jeff and his family are driving to visit his grandmother.they have driven about 30 miles, which is about 2/3 of the way. ow much
finlep [7]
Say you have 3 cakes. How many cakes would you have eaten if you ate 1/3 of the three cakes? One, you have eaten one cake, out of the three you have.

How many cakes do you have left if you eat 2/3 of the three cakes? Two, you have eaten 2 cakes, and have 1 cake left.

It is a similar approach here, except the confusing part is working "forward", when you really have to work "backward". If you have driven 30 miles, and you have driven 2 parts out of the trip when there is 3 parts of the trip, how many miles have you driven? Hint: Dividing 30 by 2 gives you what fraction of the distance to Jeff's grandmother?

Kyle divided his stamps
Marat540 [252]

Answer:

18

Step-by-step explanation:

Each page has 6 stamps. There are 3 pages. This is a simple multiplication problem, and so you do 3x6 to find the total number of stamps Kyle has. Thus, 3 times 6 is 18.

visual:

Page One: 6 stamps

Page Two: 6 stamps

Page Three: 6 stamps

6 + 6 + 6 = 18 (or just do 6x3)

Find the area of the shaded part of the triangle below. Round to the nearest tenth if needed.
konstantin123 [22]

Answer:

212.5

Step-by-step explanation:

For triangles, A = (bh)/2

You can do 15+25 to find the base, which is 40. From here do 17*40/2. You get 340. However, you need to remove the right triangle on the left side.

Again do 17*15/2, which you get 127.5.

From here subtract 127.5 from 340 and get 212.5

nydimaria [60]

The histogram which shows the results of the time trial is option B

<h3>Histogram</h3>

Given data:

12:32, 12:46, 13:30, 15:03, 13:43, 13:46, 14:20, 14:29, 12:34, 14:43, 15:26, 16:02, 16:16, 14:38, 16:55, 17:10, 14:26, 17:21, 17:58, 13:30

Grouping of data,:

12:00 - 12:59 = 3

13:00 - 13:59 = 4

14:00 - 14:59 = 5

15:00 - 15:59 = 2

16:00 - 16:59 = 3

17:00 - 17:59 = 3

  • The frequency is represented on the y-axis(number of cyclist)
  • The time is represented on the x-axis
