Answer: the z score is 1
Step-by-step explanation:
Since the head circumference for boys at birth is normally distributed,
we would apply the formula for normal distribution which is expressed as
z = (x - µ)/σ
Where
x = head circumference for boys at birth.
µ = mean head circumference
σ = standard deviation
From the information given,
µ = 34.5cm
σ = 1.3 cm
For a boy born with a head circumference of 35.8cm, the z score is
z = (35.8 - 34.5)/1.3
z = 1
Answer: 19/21
Step-by-step explanation: find the same multiple for both so you can combine them
Answer: 
2. Vertex: (-5, 4) Focus: (-6, 4) Directrix: x = -4
<u>Step-by-step explanation:</u>
The vertex form of a parabola is y = a(x - h)² + k or x = a(y - k)² + h
- (h, k) is the vertex
- p is the distance from the vertex to the focus
- -p is the distance from the vertex to the directrix
1) y = (x + 3)² - 6 → a = 1 (h, k) = (-3, -6)

Hi there, -5*10/9*8=-50/72, -50/72 simplified is -25/36. Therefore, the answer is A. -25/36
Here is a little advice use mult tke 3 jars x 2 rocks which is 6 rocks then 4 buckets by 3 rocks is 12 rocks now add 12 + 6 = that's gonna be your answer.
