Answer:

3/5

Step-by-step explanation:

The range of the cosine function is [-1, 1].  Since √41/5 is greater than 1, we eliminate answers a) and b) immediately.

If this angle lies in Quadrant IV, the "adjacent side" is positive.  Thus, the cosine of this angle must be 3/5.

Allisa [31]

Answer:

21.186%

Step-by-step explanation:

z = (x-μ)/σ,

where

x is the raw score = 2400mg

μ is the population mean = 2000mg

σ is the population standard deviation = 500mg

z = 2400 - 2000/500

z = 0.8

Probability value from Z-Table:

P(x<2400) = 0.78814

P(x>2400) = 1 - P(x<2400) = 0.21186

Converting to percentage:

0.21186 × 100

= 21.186%

Therefore, the percent of the meals

ordered that exceeded the recommended daily allowance of 2400 mg of sodium is 21.186%

Determine the mean of the data. Round to the nearest tenth. 6, 9, 15, 22, 30, 36
pshichka [43]
To find the mean you add all the numbers and divide it by the amount of numbers there is so add
6+9+15+22+30+36=118 
there is 6 number so divide 118 by 6
118/6=<span>19.6666666667 rounded to the nearest tenth it would be 20
So your mean would be 20
