The key to this problem is to write out the probabilities and determine which one is most likely and least likely (or impossible).

Drawing a black card from a standard deck of playing cards:

There are 52 cards in a playing deck, 26 are red and 26 are black.

\frac{26}{52} = \frac{1}{2}

A spinner has 5 equal sections numbered 1 through 5. You spin and land on a number less than or equal to 4.

This means that all the numbers (1, 2, 3, and 4) except 5.

\frac{4}{5}

You roll a standard number cube and get a number less than 2.

A standard cube is from 1 to 6, and 1 is the only number on the cube that is less than 2.

\frac{1}{6}

You roll two standard number cubes and the sum is 1.

The smallest number on a standard cube is 1, so you can't make the sum 1 with 2 dice.

0

If we put these in order, we get:

\frac{4}{5}, \frac{1}{2}, \frac{1}{6}, 0

So, the order going from top to bottom in the picture is: 2, 1, 3, 4

The coordinates of DEF are D(3,4), E(6,4), and F(5,9). If you translate DEF 3 units left and 2 units up, what are the coordinate
grigory [225]

EXPLANATION:

1.We must locate the points that the exercise gives us in the Cartesian plane.

2.The figure that it gives us must be moved 3 units to the left and then 2 units up.

3.To correctly translate a figure, we must add the units that the exercise indicates and towards the correct direction, if it tells us that to the left is towards the negative axis, then each of the points given in the exercise we will transfer 3 units towards the left and then add each of the points two units up, then we see that the triangle takes new coordinates for the points.

4.The new coordinates for point E are (3,6)

Pulse rates of women are normally distributed with a mean of 77.5 beats per minute and a standard deviation of 11.6 beats per mi
irakobra [83]

Answer:

a) Mean=0 and Standard deviation=1

b) The z-scores have no units of measurement

Step-by-step explanation:

When we convert all the pulse rates of women to z-scores using the formula;

z=\frac{x-\mu}{\sigma} the mean is 0 and the standard deviation is 1.

The reason is that, the resulting distribution of z-scores forms a normal distribution which has a mean of 0 and a standard deviation of 1.

b) The z-scores are standardize scores and has no units of measurement. They give us how many standard deviations below or above the mean of the corresponding values.

Karen wants to estimate the mean number of siblings for each student in her school. She records the number of siblings for each
Tamiku [17]

The sample is 200 randomly selected students.

The following things should be considered:

  • Let us assume the no of siblings for each student be x.
  • Now for determining the mean no of siblings she choose 200 students.

So, here the sample should be 200 randomly selected students.

Therefore the other options should be incorrect.

Thus we can conclude that the sample is 200 randomly selected students.
