I would say No hope this helps you.
so
y=-8/9x+4
Your y intercept is 4
For every 9 units you go (to the right) along the x axis, you go 8 units down on the y axis.
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:
34
Step-by-step explanation:
2b + 7z when b = 3, z = 4
2*3 = 6
7*4 = 28
28 + 6 = 34
Hope this helps!
