Step-by-step explanation:

Right on edge

The standard deviation is 2.08.

A standard deviation (or σ) is a measure of how dispersed the data is in relation to the mean. Low standard deviation means data are clustered around the mean, and high standard deviation indicates data are more spread out.

We have the data,

X     :   0     1     2     5     10

P(X) :  0.4  0.2  0.2  0.1  0.1

CF   : 0.4   0.6  0.8  0.9  1

Sum of fx = 2.5

Mean = 2.5

Deviation X = -2.1 -2.3 -2.1 -2 -1.5

X² = 4.41 5.29 4.41 4 2.25

fX² = 1.764 1.058 0.882 0.4 2.225

Now, standard deviation

= √4.329/1

= 2.08

Answer:

a) "impossible event"

b) "certain event"

c) Letter A.

Step-by-step explanation:

a) An event with probability 0 is said to be:

These events are called "impossible events" (but there are more complex cases where we can have probabilities 0, and the events are not necessarily impossible events)

b) An event with probability 1 is said to be

An event with a probability of 1 is an event that will happen, these events are called "certain event"

c) The probability for each outcome of an unbiased experiment of N different outcomes will be 1/N

for example, for a 6-side dice we have 6 outcomes, then the probability of each outcome is 1/6.

For the coin, we have 2 outcomes, then the probability of each outcome is 1/2

Probability of getting a head = 1/2 = 0.5

In the image, we can see that letter A is on the 0.5 value, then the correct answer here is A.

Answer:

multiply the two numbers, 2 3/4 x 1 1/3

Step-by-step explanation:

3 2/3 is your answer

Answer:

ab = 24

so ac is half, so

ac = 12

and the radius is 13,

draw a line from a to o

and its tall will be 13 because it is the radius and o is the center

now use Pythagoras rule

[tex] {a}^{2} + {b}^{2} = {c}^{2} [/tex]

put numbers

[tex] {12}^{2} + {b}^{2} = {13}^{2} [/tex]

and solve for b

b = 5

and that is the side we want

Answer:

90, 70, 20

Step-by-step explanation:

The measure of an angle is 180 so if you add up 90,70,and 20 you get a total of 180

Answer:

70, 20, 90

Step-by-step explanation:

For all triangles, the sum of the angles is 180.

I got these three angles 70, 20, 90.

To double check you can add all the angles together.

70 + 20 = 90, 90 + 90 = 180

Answer:

2x-60=180

Step-by-step explanation:

RQS = x-6

the two angles add to make 180 because they are on a straight line

so x + x-6 = 180

therfore, 2x+6 = 180

Equation/Question:

-2(x+1)+4x<-10 What’s the solution?

Answer/Way I did it:

1. Expand.

-2x-2+4x<-10

2. Simplify  -2x-2+4x to  2x-2.

2x-2<-10

3. Add 2 to both sides.

2x<-10+2

4. Simplify  -10+2 to −8.

2x<-8

5. Divide both sides by 2.

x<-8/2

6. Simplify  8/2 to  4.

x<−4
