Answer:
C. Skewed
Step-by-step explanation:
You can tell because the box in this box and whisker plot is on the right side of the line meaning that it is skewed.
Y=mx+b
m = slope
y = -3x/4 +b
4 = -3*0/4 + b
4 = b
y -3x/4 + 4
Answer:
A
E
Step-by-step explanation:
sqrt25 is 5 and since sqrt29 is bigger than sqrt 25 the inequality is true
sqrt4 is 2 and since sqrt 3 is less than 4 the inequality is false
sqrt49 is 7 and since sqrt50 is bigger than 49 it is false
sqrt64 is 8 and since 61 is smaller than 64 it is false
sqrt 36 is 6 and since sqrt 31 is smaller the equation is true
Answer:
Then the probability that exactly 6 bridges in the sample are structurally deficient is 0.1063 or 10.63%
Step-by-step explanation:
Let X the random variable of interest "number of bridges in the sample are structurally deficient", on this case we now that:
The probability mass function for the Binomial distribution is given as:
Where (nCx) means combinatory and it's given by this formula:
And we want to find this probability:

And if we use the probability mass function and we replace we got:
Then the probability that exactly 6 bridges in the sample are structurally deficient is 0.1063 or 10.63%
