1/42

First, find the probability of Willie winning the grand prize. He has 1 ticket out of the 7 total tickets, so the probability is 1/7.

Now, find the probability of Emily winning the second prize. After the grand prize winner has been announced, there are only 6 tickets left. Emily has 1, so the probability is 1/6.

Finally, multiply the two probabilities together to find the probability that they will both happen together. To multiply fractions, multiply the numerators together and multiply the denominators together. This leaves us with (1 * 1) / (7 * 6), which is easy to simplify to 1/42, which is the final probability.

The shelf is 4 feet wide and 2/3 feet deep. what is the area of the shelf?
steposvetlana [31]

Answer:

Area of the self will be =4\times \frac{2}{3}=\frac{8}{3}=2.666ft^2

Step-by-step explanation:

We have given that self is 4 feet wide and \frac{2}{3} feet deep

So length pf the shelf l = \frac{2}{3} feet

And width = 4 feet

We have to find the area of the self

We know that area is given by

Area = length × width

So area of the self will be =4\times \frac{2}{3}=\frac{8}{3}=2.666ft^2

Which of the following best explains why one graph appears skewed and one graph appears symmetric? the intervals on the x-axis o
LenKa [72]

The reason for one graph appears skewed, and one graph appears symmetric is the interval on the x-axis of the histogram is inconsistent.

<h3>What is histogram?</h3>

A histogram is the way of representation of data which is used to show the frequency distribution using the rectangle similar to a bar graph.

In the problem, the data given as,

  • In the attached image below, the histogram and box plot is shown for the ages of Elizabeth's Grandchildren and their frequency.
  • In the 3rd and 4the bar of histogram, the data is jumped from 14 to 20 instead of 15.
  • The frequency distribution in histogram for this data is inconsistent.
  • This inconsistency brought the between the two graphs.

Thus, the reason of one graph appears skewed, and one graph appears symmetric is the interval on the x-axis of the histogram is inconsistent.

s2008m [1.1K]

Answer: 3

Step-by-step explanation:

Feom the question, we are informed that students are making ornaments and each takes 1/2 of a piece of Bristol board and that they go to the cupboard and find 1 1/2 pieces of Bristol board.

The number of ornaments that they can make will be calculated by dividing 1 1/2 by 1/2. This will be:

= 1 1/2 ÷ 1/2

= 3/2 ÷ 1/2

= 3/2 × 2/1

= 3

They can make 3 ornaments
