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:

Step-by-step explanation:
Given
Shape: Trapezoid



Required
Determine the length of the second parallel side
The area of a trapezoid is:

Substitute values for Area, Height and Side1

Multiply both sides by 2


Divide both sides by 18



Hence;
<em>The length of the second parallel side is 17cm</em>
Answer:
Vertical
Step-by-step explanation:
You have a vertical line at point (6,0).
Answer:
volume = length×width×height
Step-by-step explanation:
box 1
12×2×7 = 24×7 =168
box 2
9×2×5 = 10×9 = 90
total vloume = 168+90 = 258cubic inches.
