Answer: The value of x is 2 units.
Explanation:
Since we have given that
AB and CD are two chords that are intersected externally at point E.
As we know the relation regarding the above i.e.
Here,
EB=x+1
EA=x+1+11 = (x+12)
EC=x+4
ED=x+4+1 = (x+5)
Now, we put the values in the relation given above :
Hence, the value of x is 2 units.
Answer:
1.5 Kilometers and 150000 Centimeters
Step-by-step explanation:
5 × 10 -5 kilometers in 1 1 / 2 centimeters. To convert any value in centimeters to kilometers, just multiply the value in centimeters by the conversion factor 1 / 100000 . So, 1.5 centimeters times 1 / 100000 is equal to 1.5 × 10 -5 kilometers.
I hope this helps!

Answer:
The expected number of children that can pass the fitness test in a test session is 7.5 and the standard deviation is 1.37.
Step-by-step explanation:
For each children, there are only two possible outcomes. Either they pass the health test, or they do not. Whether a child can pass the test is independent with the test result of other children. This means that we use the binomial probability distribution to solve this question.
Binomial probability distribution
Probability of exactly x sucesses on n repeated trials, with p probability.
The expected value of the binomial distribution is:
The standard deviation of the binomial distribution is:
The probability for each child to pass the fitness test is 0.75
This means that
10 independent children
This means that Find the expectation and standard deviation of the number of children can pass the fitness test in a test session.
The expected number of children that can pass the fitness test in a test session is 7.5 and the standard deviation is 1.37.
