The percentage of boys 16- to 17-years-old who wear a size 11 shoe or larger is 3.59%.
<u>Step-by-step explanation:</u>
Step 1: Sketch the curve.
The probability that X>27.9 is equal to the blue area under the curve.
Step 2:
Since μ=25.2 and σ=1.5 we have:
P ( X > 27.9 ) = P ( X−μ > 27.9−25.2 )
⇒ P ( X−μ/σ > 27.9−25.2/1.5)
Since Z=x−μσ and 27.9−25.21.5=1.8 we have:
P ( X>27.9 )=P ( Z>1.8 )
Step 3: Use the standard normal table to conclude that:
P (Z>1.8)=0.0359

Therefore , The percentage of boys 16- to 17-years-old who wear a size 11 shoe or larger is 3.59%.
Hello!
To understand this question we first need to find some common measurements to make this math easier.
One day is equal to 24 hours.
One hour is equal 60 minutes.
One day in hours would be equal to 24 · 60, or 1440 minutes.
1440 is equal to 100% of our day.
To find 50% we can then divide that value in half to get 720 minutes.
Half of that value, or 25%, is equal to 360 minutes.
Answer:
120 degrees
Step-by-step explanation:
Since p is parallel to q, <6 and <8 are congruent because of corresponding angles.
m<8=m<6
120=m<6
Since m<8 is 120, and the two angles are congruent, the m<6 is also 120 degrees.
Like 5+0=5 or maybe 5+1 and 6-1
