The following numerically ordered sequence of numbers has a mean of 17 and a median of 18.
7,a,12,15,17,b,20,22,24,25
given the information, the values of a and b must be:

Arectangle has a width of 5 cm and a length of 10 cm. if the width is increased by 3, how does the perimeter change?

Consider the polynomials given below. p(x) = x4 + 3x3 + 2x2 – x + 2 q(x) = (x3 + 2x2 + 3)(x2 – 2) determine the operation that results in the simplified expression below. 35 + x4 – 573 - 3x2 + x - 8 a. p+q b. pq c.q-p d. p-q

If p(a) = 0.70 and p(b) = 0.20, then a and b are independent events if
