7.2.35-T Question Help The pulse rates of 178 randomly selected adult males vary from a low of 40 bpm to a high of 120 bpm. Find the minimum sample size required to estimate the mean pulse rate of adult males. Assume that we want 98% confidence that the sample mean is within 4 bpm of the population mean. Complete parts (a) through (c) below. a. Find the sample size using the range rule of thumb to estimate o. n (Round up to the nearest whole number as needed.)​

Look at the following graph of the given equation. determine whether the equation is a function. explain why or why not.

Write the equation of the line that passes through (3, 4) and (2, −1) in slope-intercept form. (2 points) y = 3x − 7 y = 3x − 5 y = 5x − 11 y = 5x − 9
