suppose that a data set has an approximately symmetrical distribution, with one outlier. what could you do if you wanted to use the mean and standard deviation to characterize the data?
Answers
Answer:
The median is known as a measure of location; that is, it tells us where the data are. As stated in , we do not need to know all the exact values to calculate the median; if we made the smallest value even smaller or the largest value even larger, it would not change the value of the median. Thus the median does not use all the information in the data and so it can be shown to be less efficient than the mean or average, which does use all values of the data. To calculate the mean we add up the observed values and divide by the number of them. The total of the values obtained in Table 1.1 was 22.5
Missing alternative text , which was divided by their number, 15, to give a mean of 1.5. This familiar process isconveniently expressed by the following symbol\

A bag contains 45 dyed eggs: 15 yellow, 12 green, and 18 red. What is the probability of selecting a green or red egg.
Answers
Answer:
it's 30/45
Step-by-step explanation:
because there are 12 green and 18 red which equal 30. Then there are 45 eggs in total. So 30/45
Probability of selecting a green or red egg is equals to [tex]\frac{30}{45}[/tex].
What is probability?" Probability is defined as ratio of number of favourable outcomes to the total number of outcomes."
Formula used
Probability [tex]= \frac{Number of favourable outcomes}{Total number of outcomes}[/tex]
According to the question,
Given,
Total number of dyed eggs [tex]= 45[/tex] dyed eggs
Number of yellow eggs [tex]= 15[/tex]
Number of green eggs [tex]= 12[/tex]
Number of red eggs [tex]= 18[/tex]
Substitute the value in the formula to get the probability of each required colour egg,
Probability of green egg [tex]P(G)= \frac{12}{45}[/tex]
Probability of red egg [tex]P(R)= \frac{18}{45}[/tex]
Both are independent therefore,
P( G ∩ R) [tex]=0[/tex]
Probability of selecting a green or red egg [tex]= P(G) + P(R)[/tex]
[tex]= \frac{12}{45} + \frac{18}{45}\\\\= \frac{30}{45}[/tex]
Hence, probability of selecting a green or red egg is equals to [tex]\frac{30}{45}[/tex].

If point A is reflected across both axes, what are the coordinates of the reflected point?
Answers
Answer:
The answer is "(6,3)".
Step-by-step explanation:
In this question, the point is missing if the given point is (-6,-3) so, its solution can be defined as follows:
Throughout this question whenever we reverse the axis to the mirror at the point. The reflection of (-6,-3) is (6,3), which also is the correct value because it changes the coordinates, that's why (6,3) is the correct point.

Find the distance between the points (9, 8) and (5, 3).
Write your answer as a whole number or a fully simplified radical expression. Do not round,
___ unit
Answers
Answer:
[tex]\sqrt{41}[/tex] units
Step-by-step explanation:
To find the distance between two points, we can use the Pythagorean theorem by creating a right-angled triangle where sides a and b are the distances between the y-coordinates and x-coordinates of each point.
First let's find the distance between the x-coordinates:
(9,8): x-coordinate is 9, and (5,3): x-coordinate is 5.
9 - 5 = 4
The first side of our triangle is 4 units.
y-coordinates:
8 - 3 = 5
The second side of our triangle is 5 units.
[tex]a^{2} +b^{2} =c^{2}[/tex]
[tex]4^{2} +5^{2} =c^{2} \\16 +25 =c^{2} \\41 = c^{2} \\\sqrt{41} =\sqrt{c^{2} } \\\sqrt{41} = c[/tex]
Squareroot 41 is fully simplified as 41 is a prime number.
I have attached a picture to help visualize the triangle.

The number of green marbles based on the given ratio is 48.
What are the ratio and proportion?The ratio is the division of the two numbers.
For example, a/b, where a will be the numerator and b will be the denominator.
Proportion is the relation of a variable with another. It could be direct or inverse.
Let's say the number of blue marbles is B and the number of green marbles is G.
The ratio of blue and green marbles is 5:6.
So,
B/G = 5/6
Since B = 40
40/G = 5/6
By cross multiplication,
G = 40(6)/5
G = 48
Hence "The number of green marbles based on the given ratio is 48".
