A cardiac patient cannot walk any faster that 2.0 mph, but she has been told that she must at 8 METs. At what percent grade should the treadmill be set?

I am stumped! A park sells children and adult tickets at a ratio of 8 to 1. On Sunday, they sold 147 MORE children's tickets than adult tickets. How many tickets did the amusement park sell on Sunday? I would like to use ratios/proportions to solve this problem.

(b) Compute the mean and standard deviation of the random variable using Hx = E[x•P(x)] and ox = Hx = (Round to two decimal places as needed.)

Samantha is estimating the width of a lake. She stands at point B and looks through a long-range scope. She sees a boat shed at point A that is about 9 miles away and a tall tree at point C that is about 7 miles away. Which of the following is closest to the distance, in miles, across the lake from point A to point C?         12.9         9.7         10.6         11.4

Tyler looks at a map on his phone. He zooms in until the map scale for cenimeters to kilometers 0.3:1/5. How many cenimeters does this map use to show 1 kilometer?

If VW = 28 and UX = 39, what is ST?

Fifty-four wild bears were anesthetized, and then their weights and chest sizes were measured and listed in a data set. Correlation Results Results are shown in the accompanying display. Is there sufficient evidence to support the claim that there is a linear correlation between the weights of bears and their chest sizes? When measuring an anesthetized bear, is it easier to measure chest size than weight? If so, does it appear that a measured chest size can be used to predict the weight? Use a significance level of a =0.05. Correlation coeff, r: 0.966175 Critical r: ±0.2680855 P-value (two tailed): 0.000 Determine the null and alternative hypotheses. H1: p (Type integers or decimals. Do not round.) Identify the correlation coefficient, r. (Round to three decimal places as needed.) Identify the critical value(s). (Round to three decimal places as needed.) A. There is one critical value at r= O B. There are two critical values at r= + Is there sufficient evidence to support the claim…
