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.
Hello,
The sum of the angles of a triangle is equal to 180°.
<u>So :</u>
x = 180 - 40 - 55 = 85°
Have a nice day :)
I think the answer is B. but I'm not sure... Sorry if this doesn't help!
Answer:
The ordered pair of P'=(-8.75, 5.25)
Step-by-step explanation:
To get the ordered pair of point P' you simply have to multiply the coordinates of P by scale factor of 7/4
P:(-5,3)
P'(x,y)= (-5* 7/4, 3*7/4)
P'(x,y) = (-35/4 , 21/4)
P'(x,y) = (-8.75, 5.25)..
Thus the ordered pair of P'=(-8.75, 5.25)....
