8) Sandy tells you that she drew a right triangle with the side lengths of 8.4 cm, 14 cm, and 11.2 cm.
Is she correct? Explain why or why not. Show your work.

Yes, she can drew a right triangle with these sides

Step-by-step explanation:

To answer this question we first have to prove the Pythagorean theorem

h = hyoptenuse

a = leg 1

b = leg2

h² = a² + b²

We have to replace the values that they gave us in this formula

The hypotenuse always has to be the longest side of a right triangle

(14cm)² = (11.2cm)² + (8.4cm)²

196cm² = 125.44cm² + 70.56cm²

196cm² = 196cm²

As we can see, equality is fulfilled, so she is correct

solution:

as, mean is defined as sum of all the observations divided by total number of observations.

and , median is mid value of the data whether arranged in ascending order or descending order.

consider, roadsters:

2,3,4,5,6,7,8,9

mean =

also, median= , because number of observations is even, so median is mean of two mid values.

now, coming to bandits

2,3,4,5,6

mean =  

median = 4, as number of observations is odd.

so, roadsters has greater median as well mean than bandits.

→option a is true about the repairs performed on 2 types of cars:

bandits have lower median and mean than roadsters.

probability for j is 1/4

while

a is 1/6
