In a high school high jump contest, the height of clearing the bar ranged from 71 inches
to 84 inches. The mean height was 76 inches and the standard deviation was 3.5 inches.
What percent of the jumpers were in the group jumping below 79.5 inches? (HINT: How
many standard deviations is 79.5 inches?)

The number of members f(x) in a local swimming club increased by 30% every year over a period of x years. the function below shows the relationship between f(x) and x: f(x) = 10(1.3)xwhich of the following graphs best represents the function? graph of f of x equals 1.3 multiplied by 10 to the power of x graph of exponential function going up from left to right in quadrant 1 through the point 0, 0 and continuing towards infinity graph of f of x equals 10 multiplied by 1.3 to the power of x graph of f of x equals 1.3 to the power of x
