Two methods are proposed to measure the effectiveness of a brand of sunscreen.
Method A: Survey adults visiting a beach on a busy weekend. Ask each adult which brand of sunscreen they are using, and assess their arms for sun exposure.
Method B: Volunteers are randomly assigned to one of two brands of sunscreen. Each volunteer is asked to report back at the end of the day, and their arms are assessed for sun exposure.
Which statement is a correct interpretation of these methods?
Both methods are experiments because sun exposure is assessed in both methods.
Both methods are observational studies because neither method attempts to influence responses.
Method A is an experiment because it compares many brands of sunscreen, while method B is an observational study.
Method B is an experiment because it randomly assigns volunteers a sunscreen, while method A is an observational study.
Answers
Answer: Method B is an experiment because it randomly assigns volunteers a sunscreen, while method A is an observational study.
Step-by-step explanation:
Based on the information given, we can infer that method A is an observational study. An observational study simply refers to the study whereby the researchers just observe the impact of a rise factor without them trying to change the people or things exposed to it. This can be seen as the survey adults visited the beach on the busy weekend asking each adult the brand of sunscreen that they use and then assess their arms for sun exposure.
Method B is an experiment. An experiment refers to a test that's carried out in order to evaluate a particular hypothesis or theory. Method B is an experiment because it randomly assigns volunteers a sunscreen.
Therefore, the correct option is D.

(6,0) and (0,-8)
Step-by-step explanation:
Substitute a zero for each variable
So 4(0) - 3y = 24 to find the y-int so -3y = 24, y = -8, so y-int is (0,-8)
to find x-int y = 0 so 4x - 3(0) =24 so 4x = 24, so x = 6 so x-int is (6,0)

how much less than the mean?
1.5, 0.6, 0.7, 0.85, 5.3
Answers
Answer:
The median of the numbers is 3.66 less than the mean
Step-by-step explanation:
To find the median, find the middle of the numbers
0.6, 0.7, 0.85, 1.5, 5.4
To find the mean, add all the numbers and divide by the number of numbers
0.6 + 0.7 + 0.85 + 15 + 5.4 = 22.55
22.55/5 = 4.51
To find how less, subtract the median from the mean

In the 2009 NFL regular season, quarterback Philip Rivers of the San Diego Chargers had an average of 266 passing yards per game with a standard deviation of 79 yards. Between which two values do you expect the middle 68% of his performance to be?
Your answer
A. 108 and 424
B. 29 and 503
C. 187 and 345
D. 0 and 582
Answers
Answer:
C. 187 and 345
Step-by-step explanation:
The Empirical Rule states that, for a normally distributed random variable:
Approximately 68% of the measures are within 1 standard deviation of the mean.
Approximately 95% of the measures are within 2 standard deviations of the mean.
Approximately 99.7% of the measures are within 3 standard deviations of the mean.
In this problem, we have that:
Mean of 266 yards per game, standard deviation of 79 yards.
Between which two values do you expect the middle 68% of his performance to be?
By the Empirical Rule, within 1 standard deviation of the mean. So between 266 - 79 = 187 yards and 266 + 79 = 345 yards. The correct answer is given by option C.

Find the volume of the cone in terms of pi. A cone with a radius of 5 feet and a height of 12 feet.
Answers
Answer:
V = [tex]\pi[/tex]r^2 x height
Step-by-step explanation:
Find the volume of the cone in terms of π. A cone with a radius of 5 feet and a height of 12 feet.
Answer:-Given:-Radius (r) of the cone = 5 feet.
Height (h) of the cone = 12 feet.
To Find:-The volume of the cone.
Solution:-We know,
Formula of Volume of Cone is [tex] \frac{1}{3} [/tex]πr²h
Volume of the cone = [tex] \frac{1}{3} [/tex]× π × (5)² × 12
Volume of the cone = [tex] \frac{1}{3} [/tex]× π × 5 × 5 × 12
Volume of the cone = [tex] \frac{\pi \: × \: 5 \: × \: 5 \: × \: 12}{3} [/tex]
Volume of the cone = [tex] \frac{300\pi}{3} [/tex]
Volume of the cone = 100π in³
Volume of the cone is 100π in³.
Hence, option (d) 100π in³ is correct. [Answer]levi was designing a kite. he needs to determine the measure of

The measure of angle A is 86.
What is a kite?A kite is a flying object that is tethered to the ground by a string or a cord. It typically has a light framework of bamboo, plastic, or other materials, covered with paper or fabric, and often in the shape of a diamond or triangle.
We have,
From the figure,
We see that,
6x + 4 + ∠A = 180
Now,
∠A = 4x + 26
So,
6x + 4 + 4x + 26 = 180
10x + 30 = 180
10x = 180 - 30
10x = 150
x = 15
Now,
∠A = 4x + 26 = 4 x 15 + 26 = 60 + 26 = 86
Thus,

One pizza is $12 and a cake is $18. If Matt has $84, how many pizzas can he buy at most and still afford to buy a cake
Answers
Answer:
5 pizzas
Step-by-step explanation:
So first you subtract 18 so that you know that there is at least one cake.
84 - 18 = 66
When you get 66 dollars remaining, you divide it by 12 to see how many you can afford.
66/12 = 5.5
So because you can’t say you have an additonal amount of money, you would actually round down to 5.
So Matt can buy a total of 5 pizzas and 1 cake.
Answer:
5
Step-by-step explanation:
To find the number of pizzas Matt can buy while still being able to afford a cake set up an inequality. The inequality should look like [tex]84\geq 12x+18[/tex] where x is the number of pizzas Matt bought. Then, solve the inequality by first subtracting 18 from both sides, [tex]66\geq 12x[/tex]. Next, divide both sides by 12, [tex]5.5\geq x[/tex]. This means that Matt can buy 5 pizzas. At first, it might seem like you should round up; however, if you rounded up at all then Matt could not afford the cake, so you must round down.
A hotel restaurant has a 75% customer approval rating for its service. The restaurant has a 60% customer approval rating for its service and its food. What is the probability that a restaurant customer approves of the food if he or she approves of the service?
Answers
The probability that a restaurant customer approves of the food given that they already approved of the service is 0.8, or 80%.
What is probability?Probability can be defined as the ratio of favorable outcomes to the total number of events.
Let's use Bayes' theorem to solve this problem.
= P(approves of food | approves of service)
By Bayes' theorem, we can express this probability in terms of the probabilities of approving of the service and the food separately:
P(approves of food | approves of service) = P(approves of service and food) / P(approves of service)
We know that the overall customer approval rating for the service is 75%, so:
P(approves of service) = 0.75
We also know that the customer approval rating for both the service and the food is 60%, so:
P(approves of service and food) = 0.60
Substituting these values into the formula, we get:
P(approves of food | approves of service) = 0.60 / 0.75
P(approves of food | approves of service) = 0.8
Therefore, the probability that a restaurant customer approves of the food given that they already approved of the service is 0.8, or 80%.

Please explain, I dont understand
Answers
Answer:
7 inches
Step-by-step explanation:
Now the area of a rectangle equals to length by width or in this scenario, height by base.
Therefore, we take a look at what we already have.
We got 5 inches for height and 35 squared inches as the area.
h= 5 inches a=35squared inches b=?
*Therefore, 5 x b =35
Through substitution this becomes:
*35/5= b

Step-by-step explanation:
Same beginning
Train A: 3 hours to NorthTrain B: 2 hours and 15 minutes to Southbut train B 20 kilometers per hour faster
15 minutes from 20 kilometers per hours are 5 kilometers
So, train B is 45 kilometers travel more far than train B.

3cm : 4m

9cm : 12m
now, we can calculate the area of the dining hall using the equation 12m × 4m = 48m².
