Answer:
Do you mean 2x<2 or
X <2 or do you mean x²<2
Step-by-step explanation:
If your question is X²<2
Then
Total outcomes=5
Possible outcomes=3(-1,0,1)
Probability of x²<2=3/5
If your question means probability of2x<2
Then
Total outcomes=5
Possible outcomes=3 (-2,-1,0)
Probability of 2x<2=3/5
If your question means x< 2
Then
Total outcomes=5
Possible outcomes=4 (-2,-1,0,1)
Probability of x <2 =4/5

3 bags, sorry if this is wrong the question doesnt make much sense to me
No, 3+13>14. If it were a right triangle both sides would be equal
Answer:
34% of lightbulb replacement requests numbering between 47 and 52
Step-by-step explanation:
The Empirical Rule states that, for a normally distributed random variable:
68% of the measures are within 1 standard deviation of the mean.
95% of the measures are within 2 standard deviation of the mean.
99.7% of the measures are within 3 standard deviations of the mean.
In this problem, we have that:
Mean = 52
Standard deviation = 5
Between 47 and 52:
52 is the mean and 47 is one standard deviation below the mean.
By the Empirical Rule, 68% of the measures are within 1 standard deviation of the mean.
Since the normal distribution is symmetric, of those, 34% are within 1 standard deviation below the mean and the mean(47 and 52) and 34% are within the mean and one standard deviation above the mean(52 and 57).
So
34% of lightbulb replacement requests numbering between 47 and 52
40.72 is the answer rounded to the nearest hundredth
