Answer:

SA = 920 inches^{2}

Step-by-step explanation:

Given Data:

Slant height of square pyramid = l = 13 inches

Base edge of square pyramid = s = 20 inches

To Find Out:

Surface area of square pyramid = SA = ?

Formula:

 SA = s^{2}   +  2 * s * l

Solution:

 SA = s^{2}   +  2 * s * l

SA = 20^{2}   +  2 * 20 * 13

SA = 400  +  520

SA = 920 inches^{2}

At a manufacturing plant where switches are made, it is a known fact that 2% of all switches are defective. If two switches are
olchik [2.2K]

Answer:

The probability that exactly one switch is good is

P(x) =0.0392

Step-by-step explanation:

The probability that a switch is defective is:

P(D) = \frac{2}{100} =0.02

The probability that a switch is not defective is

P(D') = 1-P(D)=0.98

Therefore, if two switches are selected, the probability that exactly 1 is good is:

P(1=1)=P (D) P (D ') + P (D') P (D)

P(x)=(0.02)(0.98) + (0.98)(0.02)

P(x) =0.0392
