Answer:
The probability that exactly one switch is good is
Step-by-step explanation:
The probability that a switch is defective is:
The probability that a switch is not defective is
Therefore, if two switches are selected, the probability that exactly 1 is good is:
Answer:
i think [after solving] that it is option B and C
Step-by-step explanation:
Recall the rule of exponents that states that (a^b)^c = a^(bc).
Here you have:
3/4 2/3
[ 5 ]
Multiply these exponents together, obtaining 1/2.
1/2
Then we have [ 5 ] and this is equivalent to √5 (answer)
The answer would be 70 degrees.
In order to find this answer, we must first look at the cos value of an angle. The unknown angle here gives us an adjacent side of 3.4 and a hypotenuse of 10. Thus, we can use the following with cos.
Cos(A) = 3.4/10 or Cos(A) = .34
As a result, we can then use the arccos function to find the answer.
acrcos(.34) = A
70.12 = A
Then when we round, we'd get 70.
