Answer:

78% probability it contains no defects

Step-by-step explanation:

We have that:

10% have defects in shafts only.

8% have defects in bushings only.

4% have the two types of defects.

An assembly is selected arandom, what is the probability it contains no defects

Either it has at least one defect, or it has no defects. The sum of these probabilities is 100%. So

D + ND = 100

Probability that it has a defect

D = 10 + 8 +4 = 22%

No defects:

22 + ND = 100

ND = 78

78% probability it contains no defects

Find the area of a circle with a diameter of 16.
mylen [45]

Answer:

A = 64 pi

or approximately 200.96

Step-by-step explanation:

The diameter is twice the radius

d = 2r

16 = 2r

Divide by 2

16/2 = 2r/2

8 =r

The area of a circle is

A = pi *r^2

A = pi*(8)^2

   = pi *64

Or if we approximate pi as 3.14

A = (3.14) * (64)

A = 200.96

The angle looking up at the sun is 70°. A flagpole casts a shadow of 15 ft. Draw a diagram and find the height of the flagpole
dangina [55]

Answer:

The length of the flagpole be 41.2 ft .

Option (A) is correct .

Step-by-step explanation:

As given

The angle looking up at the sun is 70°.

A flagpole casts a shadow of 15 ft .

Now by using the trignometric identity .

tan \theta = \frac{Perpendicular}{Base}

\ theta = 70^{\circ}

tan\ 70^{\circ} = \frac{AB}{BC}

BC = 15 ft

tan 70° = 2.75 (Approx)

2.75 = \frac{AB}{15}

AB = 2.75 × 15

     = 41.2 ft

Therefore the length of the flagpole be 41.2 ft .

Option (A) is correct .

We make the composition of both functions:
 f (x) = x ^ 2-1
 g (x) = 2x-3
 Then:
 f (g (x)) = (2x-3) ^ 2-1
 Rewriting:
 f (g (x)) = 4x ^ 2-12x + 8
 The domain of this function is all real numbers.
