Since the positive 4 is the on the y-axis and is changed to a -7 which is a smaller number than positive 4 the graph would be shifted down

3. consider rolling a single die. we get the number d of the die. (10 points) a. if i tell you the number is less than 4 (d <

Semenov [28]

The probability of getting an even number, knowing that the number is less than 4, in the rolling of a single die is <u>1/3</u>.

The probability of an event = The number of favorable outcomes to the event/The total number of possible outcomes.

In the question, we are asked to find the probability of getting an even number, considering rolling a single die, where we get the number d of the die, and the number is less than 4 (d < 4).

For the number d, the total number of possible outcomes, given d is less than 4 in the rolling of a single die is 3 {viz. 1, 2, and 3}.

For the event of getting an even number, from all the possible outcomes, the number of favorable outcomes is 1 {viz. 2}.

Thus, the probability of getting an even number, knowing that the number is less than 4, in the rolling of a single die is <u>1/3</u>.

The standard deviation of a sample taken from population A is 17.6 for a sample of 25.

lawyer [7]

Answer:

The standard deviation of the sample mean differences is _5.23_

Step-by-step explanation:

We have a sample of a population A and a sample of a population B.

For the sample of population A, the standard deviation $\sigma_A$ is

$\sigma_A = 17.6$

The sample size $n_A$ is:

$n_A = 25$ .

For the sample of population B, the standard deviation $\sigma_B$ is

$\sigma_B = 21.2$

The sample size $n_B$ is:

$n_B = 30$ .

Then the standard deviation for the difference of means has the following form:

$\sigma=\sqrt{\frac{\sigma_A^2}{n_A}+\frac{\sigma_B^2}{n_B}}$

Finally

$\sigma=\sqrt{\frac{17.6^2}{25}+\frac{21.2^2}{30}}\\\\\sigma= 5.23$

There's no diagram shown, but if I'm right, I think it's 2/15.

Step-by-step explanation:

Part 1:

Rotation counterclockwise 90 &degree; of a point is

Here is a table of the transformation of all four points:

P(-7,0)-> P'(-0,-7) =P'(0,-7)

A(-4,2)-> A'(-2,-4)

R(-3,0)-> R'(0,-3)

K(-6,2)-> K'(-2,-6)

The initial and rotated images are shown attached.
