Given that a the four whole numbers a, a, b and c have
a mode of 7
a median of 8.5
a mean of 9
Work out the value of a, the value of b and the value of c.

a+b= 17 , ais mode=7 , b= 10 ,c =36_24=12

i will pick c put check it over to be sure

step-by-step explanation:

step-by-step explanation:

no, her answer is not correct.   we square the lengths of all sides and then determine whether the pythagorean theorem holds here:

9² + 15² = 306.   this is not equal to the square of the longest side ( that square being 395.   answer c is correct.
