Answer:
x = 117 degrees
Step-by-step explanation:
A triangle has 180 degrees in total.
A straight line is also 180 degrees in total.
180 - 101 = 79
Angles inside the triangle
79 + 38 = 117
180 - 117 = 63
63 degrees is the missing angle
x = 180 - 63
x = 117
Answer:
3,4,5,6,7,8
Step-by-step explanation:
sum of 2 with other possible numbers:
2+1, 2+2, 2+3, 2+4, 2+5, 2+6
3, 4, 5, 6, 7, 8
Since the distances were the same you can find the average speed directly by adding the speeds then dividing by 2. No need to weight anything.
If we’re considering speed regardless of direction, the average speed is:
(24 + 16) / 2 = 40 / 2 = 20mph
However if direction matters, then one number has to be negative since the directions are opposite:
(24 - 16) / 2 = 8 / 2 = 4mph (in the positive direction)
Depending on the context, either of these could be your answer.
Answer:
Mean and Variance of the number of defective bulbs are 0.5 and 0.475 respectively.
Step-by-step explanation:
Consider the provided information,
Let X is the number of defective bulbs.
Ten light bulbs are randomly selected.
The likelihood that a light bulb is defective is 5%.
Therefore sample size is = n = 10
Probability of a defective bulb = p = 0.05.
Therefore, q = 1 - p = 1 - 0.05 = 0.95
Mean of binomial random variable: 
Therefore, 
Variance of binomial random variable: 
Therefore, 
Mean and Variance of the number of defective bulbs are 0.5 and 0.475 respectively.
