Answer:
C. Stratified Sampling
Step-by-step explanation:
Based on the information provided within the question it can be said that the sampling method that is being used in this scenario is called Stratified Sampling. This method refers to when a researcher divides a population into various different groups and then chose a predefined number of samples at random from each group. Which is exactly what is happening in this scenario since Carrie divided her day into three parts (groups) and measured her mood twice at random for each part of the day (group).
Complementary is which add up to 90 °
8)
59+31=90° complementary angles.
supplementary is which add up to 180°
10) 156+24=18 supplementary angles
12)
shows right angle=3x+45=90
3x=45
x=15°
14) supplementary angles
2x+3x+25=180
5x+25=180
x=31°
16) again it makes supplementary angles
x+2x+21=180
3x+21=180
x+7=60
x=53°
Answer:
87.8
Step-by-step explanation:
0.15(92+86+88+90) + 0.2(84) +
0.2(88)
= 0.15(356) + 16.8 + 17.6
= 87.8
