3. A survey of 200 middle school students revealed the 200 students have a median weekly allowance of $10.75, and 35 percent of them receive no allowance at all. Which statement is a definite conclusion from the information provided? A. One hundred students receive an allowance of $10.75 or less B. One hundred students receive an allowance of $10.75. C. The mean allowance for the 200 students is $10.75. D. Thirty-five students receive no allowance at all.​

step-by-step explanation:

assume that you have 3 different side lengths.   apply the pythagorean theorem here:   square each of the two shortest sides; call them a and b, so that their squares are a² and b².   also square the longest side, calling the result c².

now, if a² + b² = c² is true, the triangle is a right triangle; otherwise it is not a right triangle.

an = 22 + (n-1) *6

step-by-step explanation:

an=a1+(n-1)(d)

a1 = 22   this is the first item in the sequence

d =6   this is how the sequence goes up

a)   an = 22 + (n-1) *6

b) a12 = 22 + (12-1) *6

    a12 = 22+11*6

  a12 = 22 +88

  a12 = 110
