Which of the following statements about Hannah’s claim is supported by the interval?
A) Hannah is likely to be incorrect because the difference in the sample means was 18.6−14.4=4.218.6−14.4=4.2 hours.
B) Hannah is likely to be incorrect because 9 is not contained in the interval.
C)The probability that Hannah is correct is 0.99 because 9 is not contained in the interval.
D)The probability that Hannah is correct is 0.01 because 9 is not contained in the interval.
E)Hannah is likely to be correct because the difference in the sample means (18.6−14.4=4.2)(18.6−14.4=4.2) is contained in the interval.

Answer:
20 + 3x ≥ 50
Step-by-step explanation:
After x days, John will have added 3x points to his total. The new total will be ...
20 +3x
We want that value to be at least 50, so we use the symbol "greater than or equal to" to express that relationship:
20 +3x ≥ 50
_____
Brainly makes available a table of math symbols so you can choose the appropriate one to use in your expression. The number 2 is not the same as the symbol ≥. Using incorrect symbols makes it very difficult to tell what the intended problem is.
It’s 58 because the length is increasing by 14
