Answer:
a) Mean=0 and Standard deviation=1
b) The z-scores have no units of measurement
Step-by-step explanation:
When we convert all the pulse rates of women to z-scores using the formula;
the mean is 0 and the standard deviation is 1.
The reason is that, the resulting distribution of z-scores forms a normal distribution which has a mean of 0 and a standard deviation of 1.
b) The z-scores are standardize scores and has no units of measurement. They give us how many standard deviations below or above the mean of the corresponding values.
Question 1:
For this case we must rewrite the following equation:
If we add 3x to both sides of the equation we have:
Thus, we have that an equivalent expression is option C.
Answer:
Option C
Question 2:
For this case we must solve the following equation:
Subtracting 5 from both sides of the equation we have:
Dividing between -5 on both sides of the equation we have:
Answer:
Option B
Answer: 76 meters
Step-by-step explanation:
top side left blank = 18 because it is congruent to the bottom
left side blank is 4 + 4 + 4 (right side lengths added)
left side blank is 12
add all side lengths together for perimeter
12 + 18 + 4 + 8 + 4 + 8 + 4 + 18 = 76
76 meters
