Step-by-step explanation:
From the question we are told that:
Number of Factor study 
Level 
Sample size 
Generally the umber of participants needed for the study is mathematically given as
Answer: c
Step-by-step explanation:
105 x 4 = 420
63 x 7 = 441
420 + 441 = 861
42 / 28 = 1.5
Therefore if we multiply 35 by 1.5 it would be:
52.5
Step-by-step explanation:
Here we can see it is a quadrilateral so
x + 108° + 65° + 53° = 360° ( being sum of angles of quadrilateral)
226° + x =360°
x = 360° - 226°
Therefore x = 134°
Answer:
$35.7
Step-by-step explanation:
you can convert 15% to a decimal by dividing by 100.
15/100 = .15
if you multiply the decimal by the cost of the shirt you get how much the discount is.
0.15 * $42 = 6.30
so a 15% discount on a $42 shirt is $6.30 off. So you subtract the discount from the total cost.
$42 - $6.30 = $35.70 that is the sale price of the shirt.
