Answer:

x = 38

∠P = 26º

Step-by-step explanation:

The sum of the angle in a triangle is 180

x + (x + 78) + (x - 12) = 180

Combine like terms

3x + 66 = 180

Subtract 66 from both sides

3x = 114

Divide both sides by 3

x = 38

-----------------------

∠P = x - 12

∠P = 38 - 12

∠P = 26º

A random sample of 85 adults found that the average calorie consumption was 2100 per day. Previous research has found a standard
denpristay [2]

Answer:

$15600

Step-by-step explanation:

Minimum number of samples can be calculated using the formula:

N≥(\frac{z*s}{ME})^2 where

  • N is the sample size
  • z is the corresponding z-score for 95% confidence level (1.96)
  • s is the standard deviation of the calorie consumption (450 cal.)
  • ME is the margin of error that the researcher is willing to accept. (50 cal)

N≥(\frac{1.96*450}{50})^2 =311.2

Therefore, minimum required sample size for 50 cal standard error in 95% confidence is 312

Since the survey costs $50 for each person then the survey costs minimum

50*312=$15600
