Problem 2
The figure has one line of symmetry.
This line is vertical and passes through the direct center. Imagine folding one side to have it land perfectly on the other side.
================================
Problem 3
The letter Z has rotational symmetry.
If we were to look at the letter, close our eyes, and then rotate it 180 degrees (or have a friend do so), we wouldn't see any difference if we opened our eyes again. The "before" and "after" images being identical is what gives it rotational symmetry. Put another way, rotating the letter 180 degrees has it line up with itself.
Answer:
Step-by-step explanation:
The question is incomplete. The complete question is:
Based on data collected by the National Center for Health Statistics and made available to the public in the Sample Adult database (A-5). an estimate of the percentage of adults who have at some point in their life been told they have hypertension is 23.53 percent. If we select a simple random sample of 20 U.S. adults and assume that the probability that each has been told that he or she has hypertension is .24. find the probability that the number of people in the sample who have been told that hypertension will be: a) Exactly three (b) Three or more (c) Fewer than three (d) Between three and seven, inclusive
Solution:
This is a binomial probability distribution. If an adult is selected randomly, the outcome is either he has been told that he has hypertension or he has not been told. The probability of success, p would be that a randomly selected adult, x has been told. Therefore,
p = 0.24
n = 20
a)We want to determine P(x = 3). From the binomial probability distribution calculator,
P(x = 3) = 0.15
b) P(x ≥ 3) = 0.89
c) P(x < 3) = 0.11
d) P(3 ≤ x ≤ 7)
It would be P(x ≤ 7) - P(x ≥ 3)
P(x ≤ 7) = 0.92
Therefore,
P(3 ≤ x ≤ 7) = 0.92 - 0.89 = 0.03

False

What the attached image says that if two solids with equal heights and base areas are cut by any parallel plane to their bases then sections of equal area (volume) would be produced in them
