borishaifa [10]

The area of each triangular face is 40 square feet

<em><u>Solution:</u></em>

Given that,

Square pyramid has a base area of 64 square feet

The pyramid’s total surface area is 224 square feet

The total surface area of a regular pyramid is the sum of the areas of its lateral faces and its base

<em><u>Therefore, total surface area of square pyramid is given as,</u></em>

Total surface area = base area + 4(Area of traingular face)

Let "x" be the area of each traingular face

224 = 64 + 4(x)\\\\224 - 64 = 4x\\\\4x = 160\\\\x = 40

Thus area of each triangular face is 40 square feet

IgorLugansk [536]

Answer:

np = 81  , nQ = 99

Step-by-step explanation:

Given:

X - B ( n = 180 , P = 0.45 )

Find:

Sampling distribution has an approximate normal distribution

Computation:

nP & nQ ≥ 5

np = n × p

np = 180 × 0.45

np = 81

nQ = n × (1-p)

nQ = 180 × ( 1 - 0.45 )

nQ = 99

Therefore, sampling\ distribution\ has\ an\ approximately\ normal\ distribution.
