Probability that a randomly selected adult has an IQ less than 137 is 0.9452
<u>Step-by-step explanation:</u>
<u>Step 1: </u>
Sketch the curve.
The probability that X<137 is equal to the blue area under the curve.
<u>Step 2:
</u>
Since μ=105 and σ=20 we have:
P ( X<137 )=P ( X−μ<137−105 )= P(X−μ/ σ< 137−105/20 )
Since x−μ/σ=Z and 137−105/20=1.6 we have:
P (X<137)=P (Z<1.6)
<u>Step 3: </u>
Use the standard normal table to conclude that:
P (Z<1.6)=0.9452
∴ probability that a randomly selected adult has an IQ less than 137 is 0.9452.
Pyramid Surface Area = (½ * Perimeter of Base * Slant Height) + Base Area
Perimeter of Base = 6 * 4 = 24
Base Area = 6 * 6 = 36
Pyramid Surface Area = (½ * Perimeter of Base * Slant Height) + Base Area
Pyramid Surface Area = (½ * 24 * 6) + 36
Pyramid Surface Area = 72 + 36
Pyramid Surface Area = 108 square inches
Answer: A union B = B
The first one should’ve said A intersects B = A because the entirety of A exists in B
