Step-by-step explanation:
For each bulb, there are only two possible outcomes. Either they are defective, or they are not. This means that we solve this problem using the binomial probability distribution.
Binomial probability distribution
The binomial probability is the probability of exactly x successes on n repeated trials, and X can only have two outcomes.
In which is the number of different combinatios of x objects from a set of n elements, given by the following formula.
And p is the probability of X happening.
In this problem we have that:
There are 100 bulbs, so .
3% are defective, so .
a) 0
b) 1
c) 2
d) 3
e) 4
e) 5
Answer:
3. x = 11.6
4. f = 2 g = 2
Step-by-step explanation:
3) (3x - 7) + (4x + 6) = 90 --> x = 11.6
4) 3f + 1 = 5f - 15 ---> f = 2
6g - 5 = 3f + 1
6g = 3(2) + 6 ---> g = 2
Answer:
Angle 1= 147
Angle 2= 33
Step-by-step explanation:
(4a+7) + (a-2) = 180
4a+7+a-2=180
5a+5=180
5a=175
a= 35
plug in 35 for A to find measurements
4(35) +7 = 147
(35) -2= 33
Because the earth is round, the distance seen on a flat map is a lot further than the distance on a globe, because of distortion. So following the circle that goes through these 3 points ( Florida, Alaska and the Philippines) it is a shorter distance to fly over Alaska.
I’m not sure what that is
