Answer:
okay
Step-by-step explanation:
complementary angles are angles that add up to 90 degrees
so what you would do is take each number that you have and subtract it from 90
In the first one you would
1. take 90-80
2. you get your answer of 10!
i hope this helps :)
Step-by-step explanation:
a
the study is experimental as we do not just observe students performance. 2 techniques were also randomly assigned. there is control over teaching techniques and performance is also observed.
b.
these are the 3 factors: high school, instructions type, scores.
high school has 2 levels. level 1, is 3 high school. level 2: each high school has 4 sections and these 4 have 24 students.
instructions type: 1 level divided into standard and computer based.
scores: 0 ( no level)
c.
high school has between subject combination since there are 3 schools and 4 sections.
instructions type has between too. since there are two different types.
we have 24 students in each section which are within subjects.
d.
score on test is dependent variable
e.
student is basic experimental unit.
Answer:
200 rounded to the nearest hundredth
Step-by-step explanation:
Acute is about 30 degrees so 30+30=60
so a right angle is 90 degrees right so 90 + 60 =150 round it to the nearest hundredth and you have 200 that's how i got my answer :))
Answer:
P(company) = P(ride with friends) + P(with parents) = .23 + .4 = .63 0r 63%
Step-by-step explanation:
The 3 different case scenarios are independent of one another:.37 + .23 + .4 = 1
P of two of them occurring is found by adding their individual Probabilities
