Answer:
A = 37 degrees ; B = 82 degrees
Step-by-step explanation:
the angle A plus 143 must measure 180 degrees
angle A = 180 - 143 = 37 degrees
the sum of the inner angles of a triangle is 180 degrees
A + B + C = 180
37 + B + 61 = 180
B = 180 - 98 = 82 degrees
<span>1. </span>When given a raw score, it must be converted
into a z-score (standard score). Raw scores cannot be placed on a normal
distribution curve because they do not have the same means and standard
deviations, but when it is converted into a z-score, the number of standard
deviations above or below the population mean can be measured. The z-scores on
the center are average, the scores on the left are lower than average and the
scores on the right are higher than average.
<span>2. </span>A z-score is a standard score which can be
placed on a normal distribution curve. A z-score indicates the distance of the
standard deviations from the mean (center of the curve).
Answer:
13:12
Step-by-step explanation:
52% 2400 = 1248
48% 2400 = 1152
Reduce to 13/12 = 13:12
Answer: the second and the third one are right
Step-by-step explanation:
Answer:
B - 108
Step-by-step explanation:
A regular pentagon is 540 degrees. Divide 540 by 5 (since there are five sides) which equals 108 degrees.
