Find the value of:
a) 5x when x = 6

B) 3y when y = -7

Which of the following graphs represents the function f(x) = 2^x

What are the steps to solving the inequality 3b + 8 ≥ 14?

The brain volumes (cm cubed) of 50 brains vary from a low of 904 cm cubed to a high of 1488 cm cubed. use the range rule of thumb to estimate the standard deviation s and compare the result to the exact standard deviation of 175.5 cm cubed, assuming the estimate is accurate if it is within 15 cm cubed
