Find the probability that a point is chosen randomly inside the rectangle is in each given shape...
Arlecino [84]

By taking the quotients between the areas, we see that:

  • a) P = 0.275
  • b) P = 0.85

<h3>How to find the probabilities?</h3>

First we need to find the areas of the 3 shapes.

For the triangle, the area is:

T = 3*5/2 = 7.5

For the blue square, the area is:

S = 3*3 = 9

For the rectangle, the area is:

R = 10*6 = 60

Now, what is the probability that a random point lies on the triangle or in the square?

It is equal to the quotient between the areas of the two shapes and the total area of the rectangle, this is:

P= (7.5 + 9)/60 = 0.275

b) The area of the rectangle that is not the square is:

A = 60 - 9 = 51

Then the probability of not landing on the square is:

P' = 51/60 = 0.85

Jacob and his father measured the lengths of scrap wood in their yard. Make a line plot of their data.
drek231 [11]

The line plot is used to show the lengths of the scrap woods using check marks above the line

<h3>How to draw the line plot</h3>

From the question, we have the following frequency table

<u>Lengths      Frequency</u>

4\frac 18                       2

4\frac 14                       3

4\frac 38                       1  

4\frac 12                       6

4\frac 58\\                       1

4\frac 34                      2

4\frac 78                      2

5                         1

Next, we plot the number line.

Such that the lengths of the scrap woods are on the x-axis while their frequencies are on the y-axis

See attachment for the line plot

25/10 as a mixed number
Anvisha [2.4K]
A mixed number is an integer and a fraction that is less than one (remember that x/x = 1.) 
To simplify 25/10, calculate how many times 10 goes into 25 by dividing 25 by 10. The answer is 2 with a remainder of 5 (10 x 2 = 20, 25-20 = 5).
The mixed number is 2 and 5/10, which simplifies to 2 1/2.
