Diego is planning to make a wooden cookbook stand for his mom. the depth of the stand will be 10 inches and will hold a cookbook at a 40°
angle, as shown in the following design,
40°
10 in
diego wants to know if the length of the slanted side will be large enough to hold a cookbook. which equation can be used to find x, the length
of the slanted side?
a sin(40) = 10 in
b. cos(40%) = 10 in
c. tan(40°) = 10 in
d. cos(40) = 10 in

You are at a restaurant and owe $38 for your meal. you want to leave a 20% tip. how much will your tip be?

For what values of the variable x is the expression square root of 7x+14+ square root of 7-x a real number?

It appears that people who are mildly obese are less active than leaner people. one study looked at the average number of minutes per day that people spend standing or walking. among mildly obese people, the mean number of minutes of daily activity (standing or walking) is approximately normally distributed with mean 376 minutes and standard deviation 64 minutes. the mean number of minutes of daily activity for lean people is approximately normally distributed with mean 528 minutes and standard deviation 107 minutes. a researcher records the minutes of activity for an srs of 7 mildly obese people and an srs of 7 lean people. use z-scores rounded to two decimal places to answer the following: what is the probability (image for it appears that people who are mildly obese are less active than leaner people. one study looked at the averag0.0001) that the mean number of minutes of daily activity of the 6 mildly obese people exceeds 420 minutes? what is the probability (image for it appears that people who are mildly obese are less active than leaner people. one study looked at the averag0.0001) that the mean number of minutes of daily activity of the 6 lean people exceeds 420 minutes?
