Answer:

a 0.20

Step-by-step explanation:

The standard error of the mean can be calculated using the formula

SE=\frac{s}{\sqrt{N} } where

  • s is the population standard deviation of the time spend on the computer (1.4 hours)
  • N is the sample size of the data collected. (49)

Using the numbers SE=\frac{1.4}{\sqrt{49} } =0.20

Answer??? please answer
Aliun [14]

Answer:

∠ 1 = 94°

Step-by-step explanation:

The exterior angle of a triangle is equal to the sum of the 2 opposite interior angles.

130° is an exterior angle of the triangle, then

∠ 1 + 36° = 130° ( subtract 36° from both sides )

∠ 1 = 94°
