If a value of 103° is added to the data, how does the mean change?
The mean increases by 1.7°.
The mean decreases by 1.7°.
The mean increases by 8.6°.
The mean decreases by 8.6°.
Answers
Answer:
The mean increases by 1.7°
Step-by-step explanation:
1) Find the mean of the numbers given first
Mean = sum of number ÷ number of numbers
Sum of numbers = 58 + 61 + 71 + 77 + 91 + 100 + 105 + 102 + 95 + 82 + 66 + 57 = 965
Number of numbers = 12
965 ÷ 12 = 80.41666....2) Find the mean of numbers including the additional 103
Sum of numbers = 58 + 61 + 71 + 77 + 91 + 100 + 105 + 102 + 95 + 82 + 66 + 57 + 103 = 1068
Number of numbers = 13
1068 ÷ 13 = 82.15384623) Find the difference
If we use the results rounded to one decimal place we will be left with 80.4 and 82.2
82.1538462 - 80.41666... = 1.7The answer closest to the options given would be 'The mean increases by 1.7'Hope this helps, have a lovely day :)

Sandy used a virtual coin toss app to show the results of flipping a coin 100 times, 500 times, and 1,000 times. Explain what most likely happened in Sandy's experiment.
Sandy's experimental probability was closest to the theoretical probability in the experiment with 100 flips.
Sandy's experimental probability was closest to the theoretical probability in the experiment with 500 flips.
Sandy's experimental probability was closest to the theoretical probability in the experiment with 1,000 flips.
Sandy's experimental probability was exactly the same as the theoretical probability for all three experiments.
Answers
Answer:
As the flips increase, the experimental probability should get closer to the theoretical probability. Meaning that the trial with 1000 coin flips should be closest to the theoretical probability, Hope this helps lmk if its correct
Answer:
the probability of flipping a coin and it landing on heads and tails are 50/50 because theres 2 options.
if you flip it 100 times the probability would be 40-60 percent of the flips would land on heads OR tails
Same with 500, 1000, and so on

Multiply the pairs of numbers and match them with their products. Tiles (-5)(4.2) (-7)(-3) (4) (5) (2.5)(-9) Pairs 22.5 21 -22.5 -21 111
Answers
Here are the pairs matched with their products:
- (-5)(4.2) matches with -21
- (-7)(-3) matches with 21
- (2.5)(-9) matches with -22.5
Pairs (4) and (5) do not have corresponding products in the given options.
(-5)(4.2) = -21
(-7)(-3) = 21
(4)(5) = 20
(2.5)(-9) = -22.5
So, the pairs of numbers and their products are as follows:
(-5)(4.2) = -21 matches with -21.
(-7)(-3) = 21 matches with 21.
(4)(5) = 20 matches with 20.
(2.5)(-9) = -22.5 matches with -22.5.

Explain how to use a pattern to find the product of a decimal
Answers
Answer: Remove, Multiply, Add (RMA)
Step-by-step explanation:
I'll share a method I use. it is removed, multiply, and add. first, you have to remove the decimals from the problem, multiply them, and add the decimals back into the problem. count the number of how many numbers are behind the decimal. for example, let's take 3. after you multiply, count three spaces to the left and place the decimal. let's take 3.12 x 2.7. first, remove the decimals. after you do that, you're left with 312 x 27. do the multiplication, and then count the number of how many numbers are behind the decimals. so, that would be three. your answer for the mutiplication problem is 8,424. since there are three spaces, you would count one, two three. to the left of 8,424. therefore, the answer is 8.424

For five days, Diego recorded the lengths, in minutes, of his walk to school. The mean for his data is 11 minutes. Determine which data set below is Diego’s, and prove that your choice is correct.
Answers
Data Set A: 9, 11, 13, 10, 12
Data Set B: 8, 10, 12, 14, 16
Data Set C: 10, 10, 10, 10, 10
Data Set D: 11, 11, 11, 11, 11
To find the mean, we sum up all the values in each data set and divide by the number of values:
Data Set A: (9 + 11 + 13 + 10 + 12) / 5 = 11 minutes
Data Set B: (8 + 10 + 12 + 14 + 16) / 5 = 12 minutes
Data Set C: (10 + 10 + 10 + 10 + 10) / 5 = 10 minutes
Data Set D: (11 + 11 + 11 + 11 + 11) / 5 = 11 minutes
Comparing the mean of each data set to 11 minutes, we can see that only Data Set A and Data Set D have a mean of 11 minutes. However, to prove that our choice is correct, we need to analyze the individual values in the data set.
In Data Set A, we can observe that the values are relatively close to 11 minutes, with some values slightly above and below. This variation suggests a realistic scenario where Diego's walk to school might take slightly different amounts of time each day.
In Data Set D, all the values are exactly 11 minutes. While it is not impossible for Diego's walk to consistently take exactly 11 minutes each day, it seems less likely than having some variation in the durations.
Based on these observations, we can conclude that the most plausible data set for Diego is:
Data Set A: 9, 11, 13, 10, 12
This data set has a mean of 11 minutes and exhibits a realistic variation in walk durations, making it the most likely choice for Diego's recorded lengths.
