Answer:
13 units
Step-by-step explanation:
Rectangle ABCD has coordinates A(-1,-6), B(-1,7), C(1,7), D(1,-6)
We want to find the length of AB.
We use the absolute value method to find the length of AB.
Since the first coordinates are the same for A(-1,-6) and B(-1,7).
The distance is given by;
The length of AB is 13 units.
Answer:
See the explanation and figure attached.
Step-by-step explanation:
For this case the first step is order the data on increasing order and we got:
0,3,4,5,6,7,9,12,12,15,18,18,19,22,24,24,,25,30,33,36
For this case we assume that the lower class limit is -0.5 and each class present a width of 10 so we have this:
Interval Frequency Relative Frequency
[-0.5-9.5) 7 7/20=0.35 (35%)
[9.5-19.5) 6 6/20=0.30 (20%)
[19.5,29.5) 4 4/20=0.2 (20%)
[29.5-39.5] 3 3/20 =0.15 (15%)
Total 20 100%
The relative frequency is calculated as , where
represent the frequency for the interval and n =20 the total of values given.
And then the histogram is on the figure attached.
As we can most of the values are on the left part so then we can conclude that the distribution on this case is skewed to the right. (Mode<Median<Mean)
Answer:
<em>Expected Payoff ⇒ $ 1.50 ; Type in 1.50</em>
Step-by-step explanation:
Considering that 1 out of the 100 tickets will have a probability of winning a 150 dollar prize, take a proportionality into account;
<em>Thus, Solution ; Expected Payoff ⇒ $ 1.50</em>
