Answer:
The correct answer is a) Mean =13173.6; median is 12765 no mode ; The median is the best choice because it is not skewed by the high outlier.
Step-by-step explanation:
Step 1
Arrange the data starting from the smallest to the biggest value. The arranged values are listed here as 11850, 12700,12765,13075,15478.
Step 2
Read the median and determine the mode in this data set.
The median is the value in the center which is 12765. Since every value only appears once, there is no mode for this data set.
Step 3
Calculate the mean of this data set. The mean is calculated by adding up all the values and dividing by the number of distance data available. In this case the data has 5 values, we will divide by 5. This calculation is shown below,
The mean for the data set is 13173.6
Step 4
The best measure of central tendency for this data is the median because it is not skewed by the high outlier. The mean is bigger than 4 of the data points and is skewed by the biggest distance.
whatever you do to one side, you must do to the other side to keep the equation balanced.
in order to isolate the variable (x), you need to divide by 2. Since you are dividing the right side by 2, then you must divide the left side by 2.
-10÷2 = 2÷2x
-5 = 1x
-5 = x
The second answer is correct
X-intercepts are points where the graph intersects the x-axis, i.e. when y=0.
Substitute y=0 and solve for x:
y=x^2-3x+2
0=x^2-3x+2
0=(x-2)(x-1)
By the zero product property, we deduce x-2=0 or x-1=0, i.e. x=1 or x=2.
2 is not a composite number as it can't be divided rather than 1 or other number.
hope it helps!
