<u>Corrected Question</u>

The blueprint for the Moreno Moreno​'s living room has a scale of 2 inches equals 7 feet.The family wants to use a scale of 1 inch equals = 6 feet. What is the width of the living room on the new​ blueprint? A rectangle is labeled width = 12 inches.

Answer:

7 Inch

Step-by-step explanation:

The width of the room on the old blueprint = 12 Inches

<u>Scale on the old blueprint: </u>

2 inches = 7 feet.

Therefore: 1 Inch =7/2 feet

12 Inches =12 X 7/2 feet =42 feet

The actual width of the room is 42 feet.

<u>Scale on the new blueprint</u>

1 inch equals = 6 feet; which we can reorder as:

6 feet=1 inch

1 feet =1/6 Inch

Daniel drew a toy from a treasure chest containing 30 different toys. He selected a bouncy ball without replacement and then sel
borishaifa [10]

Answer:

Pr = \frac{1}{870}

Step-by-step explanation:

Given

n =30

Required

Probability of selecting 2 toys of different types

From the question, we understand that all toys are different i.e. 1 of each type.

And the selection is without replacement;

So, after the first toy is selected; there are n - 1 toys left.

So, the probability is:

Pr = \frac{1}{n} * \frac{1}{n - 1}

Substitute n =30

Pr = \frac{1}{30} * \frac{1}{30- 1}

Pr = \frac{1}{30} * \frac{1}{29}

Pr = \frac{1}{30*29}

Pr = \frac{1}{870}
