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
Basically, what you need to do is subtract 275 from 425. When you do that, you get 150, so that was the change in her score. I hope this helps! :)
Since r = h, we can substitute that into the equation
<span>V = pi * r^2 * r = pi * r^3 </span>
<span>Since we know the volume, we can put that in too. </span>
<span>64 pi = pi * r^3 now let's divide both sides by pi. </span>
<span>64 pi/pi = pi * r^3/pi </span>
<span>64 = r^3 </span>
<span>cuberoot(64) = r </span>
<span>cuberoot (2^6 )=r </span>
<span>4 = r</span>

9 Ibs(pounds) + 6 oz(ounces) ⇒ ounces
First, let's find out how many 1 pound is equal to in ounces.
Since 1 pound is equal to 16 ounces, multiply the 9 pounds by 16.
Now, add the remaining 6 ounces to 144 ounces, which is also 9 pounds.
The answer is 150 ounces.
Hope this helps!☺
Answer:
x = 11.
Step-by-step explanation:
We have 2 lines crossing 3 parallel lines so:
5/6 = x-1 / 12
6(x-1) = 5*12
6x - 6 = 60
6x = 66
x = 11.
