Answer:
The base is 16
Step-by-step explanation:
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.
The answer is 45.55 as the circumference
For solving of the area of a square pyramid, we can use the formula below:
A=a²+2a sqrt (a²/4 +h²)
where s for the slant height, r for the a/2, where a is the side length and h for the height
Substitute the values,
A=40²+(2*40) SQRT (40²/4 +21²)
A=3920
The answer is 3920 for the area of the square pyramid.
