Tell whether the triangle is a right triangle. Explain.

Mathematics
1 answer:
kozerog [31]3 years ago

Answer:

D

Step-by-step explanation:

Using Pythagoras' identity for right triangles

The square on the hypotenuse is equal to the sum of the squares on the other 2 sides.

Here PR is the hypotenuse, thus

13² = 169

5² + 12² = 25 + 144 = 169

Thus Δ PQR is a right triangle because 5² + 12² = 13² → D

Answer:

Total  probability value is 1

P(green) = 0.2 , P(brown) = 0.54

Given P(red) = P(yellow) = x

Total Probability = P(green) + P(Brown) + x + x

1 = 0.2 + 0.54 + 2x

1 - 0.74 = 2x

x = 0.13

P(red) = P(yellow) = 0.13

Now number of times it landed on each color :

On \ red :\\P(red) = \frac{number \ of \ times \ on  \ red}{1200} \\\\0.13 *1200 = number \ of \ times \ on \ red\\number \ of \ times \ on \ red\\ = 156\\

Since P(red) = P(yellow) , the number of time on yellow and red are same.

On \ yellow :\\number \ of \ times \ on \ yellow = 156

On \ green :\\P(green ) = \frac{number \ of \ times \ on \ green}{1200}\\\\0.2 *1200 = number \ of \ times \ on \ green\\\\number \ of \ times \ on \ green = 240

On \ Brown : \\P(brown) = \frac{number \ of \ times \ on \ brown}{1200}\\\\0.54 *1200 = number \ of \ times \ on \ brown\\number \ of \ times \ on \ brown = 648

Answer :

Red      156

Green   240

Brown   648

Yellow   156

HELP ASAP PLEASE!!!!!!!!!!!

Look in the table at the column that has 1 minute and 4.25 pages. Printer A prints 4.25 pages in 1 minute which is a rate of 4.25 pages per minute. The rate of printing is the slope in the equation. A rate of 4.25 pages per minute is represented by the equation y = 4.25x, where 4.25 ids the slope of the equation.

We are told that Printer A prints faster than Printer B, so Printer B must have a lower rate of printing than Printer A. The equation for Printer B must have a slope less than 4.25.

There are two choices which have a slope less than than 4.25.

Answer: y = 4.2x; y = 4x
