What is the mean for Doctor A’s data set on contacts? What is the mean for Doctor B’s data set on contacts? Write a sentence comparing the number of people who wear contacts in the two data sets.
Answers
Answer:
The mean for Doctor A's set of contacts is 107.7 and the mean for Doctor B's set of contacts is 118.6. I'll let you do the rest :)
A little reminder about mean: mean is when you add up all the numbers then divide by how many numbers there are, hoped this helped (*^▽^*)
Answer: Doctor A's set of contacts is 107.7 and the Mean for Doctor B's set of contacts is 118.6.
Step-By-Step Explanation: Upon further examination of the data sets, it is interesting to note that the age groups represented in the first and second sets differ significantly. The first set had a higher percentage of individuals aged 40 and above, while the second set had a higher percentage of individuals aged 20-30. This information could provide valuable insights into age-related trends in eye care practices and could potentially lead to the development of more targeted treatment options for different age groups.
Furthermore, it is important to consider other factors that may influence the wearing of contact lenses, such as geographical location and occupation. It would be interesting to analyze data sets from different regions and industries to identify any patterns or trends that may emerge.
In conclusion, the analysis of data sets related to eye care practices can provide valuable insights into different aspects of our lives. It is essential to continue exploring and analyzing such information to make informed decisions and improve the quality of eye care for those who wear contact lenses.

Find the surface area of a triangular prism that has a height of 11 meters and the triangular base shown. All dimensions are in meters.
S
A
=
m
2
Answers
Answer:
146 m²
Step-by-step explanation:
The total base area = base x length = 4 x 11 = 44 (1)
The area of each triangular surface = /2 x base x height = 1/2 * 4 * 3.5 = 7 and the areas of both triangular surfaces = 2 x 7 = 14 (2)
The surface area of each of the lateral surfaces = side of triangle x length = 4 x 11 = 44
The area of both lateral surfaces = 2 x 44 = 88 (3)
Adding up (1), (2) and (3) gives us 146 m² as the total surface area

Rectangle A has area of 40cm² and length 8cm. The area of rectangle B is one-half the area of rectangle A. The rectangle have the same length. What is the width of rectangle B ?

A coin is tossed 3 times and a sequence of heads and tails is recorded.
a) Determine the number of points in the sample space
b) Construct a tree diagram and list the sample space
Find the probability that:
c) No heads are tossed
d) Exactly one head is tossed
e) Three heads are tossed
Answers
Solution:
Total number of trials = 250.
Number of times three heads appeared = 70.
Number of times two heads appeared = 55.
Number of times one head appeared = 75.
Number of times no head appeared = 50.
In a random toss of 3 coins, let E1, E2, E3 and E4 be the events of getting three heads, two heads, one head and 0 head respectively. Then,
(i) getting three heads
P(getting three heads) = P(E1)
Number of times three heads appeared
= Total number of trials
= 70/250
= 0.28
(ii) getting two heads
P(getting two heads) = P(E2)
Number of times two heads appeared
= Total number of trials
= 55/250
= 0.22
(iii) getting one head
P(getting one head) = P(E3)
Number of times one head appeared
= Total number of trials
= 75/250
= 0.30
(iv) getting no head
P(getting no head) = P(E4)
Number of times on head appeared
= Total number of trials
= 50/250
= 0.20

Surface Area = 2(wl+hl+hw)
Therefore,

= 2(w * l + h * l + h * w)
= 2(14 * 24 + 11 * 24 + 11 * 14)
