Answer:
a = - 6
Step-by-step explanation:
Given
- 6(a + 5) + 5a = 12 + 6a ← distribute and simplify left side
- 6a - 30 + 5a = 12 + 6a
- a - 30 = 12 + 6a ( subtract 6a from both sides )
- 7a - 30 = 12 ( add 30 to both sides )
- 7a = 42 ( divide both sides by - 7 )
a = - 6
Step-by-step explanation:
Calculate and compare the z scores.
z = (x − μ) / σ
For the male:
z = (1700 − 3277.9) / 571.6
z = -2.76
For the female:
z = (1700 − 3091.6) / 625.7
z = -2.22
The absolute value of the male z score is greater than the absolute value of the female z score. Therefore, the male newborn's weight is more extreme.

Answer:
B. 16
Step-by-step explanation:
To find the median, you must first order the numbers from least to greatest
12
12
14
18
20
23
Next, you look for the middle number. If there is no middle number, you look for the middle 2 numbers. In this case, we will need to use the middle 2 numbers. They are 14 and 18. To find the median, you must add 14 and 18 then divide it by 2.
14 + 18 = 32
32/2 = 16
So, our answer is B. 16
