Answer:
B
Step-by-step explanation:
280 + 5(–5) + (–42) + 2(75) + (–200)
280 - 25 - 42 + 150 - 200
280 - 67 + 150 - 200
280 - 67 - 50
213 - 50
= $163
Answer: Minimum: 20
Quartile Q1: 23.5
Median: 27
Quartile Q3: 31
Maximum: 35
Step-by-step explanation: The five number summary gives you a rough idea about what your data set looks like. For example, you’ll have your lowest value (the minimum) and the highest value (the maximum) or where data is more concentraced. The main reason you’ll want to find a five-number summary is to find more useful statistics, like the interquartile range IQR, sometimes called the middle fifty.
It is 1/4.
9/9=1
36/9=4
9/3611/4
Answer:
x,y will be in the ratio 2:3
Step-by-step explanation:
Given that a biased coin has probability 0.6 of turning up heads
In other words, number of heads we obtain by tossing the coin would be binomial with p = 0.6 and q =1-p =0.4
If you toss one time, the distribution of U, no of heads would be
U 0 1
p 0.4 0.6
Winning amount would be 0.6x and losing amount would be 0.4y
If these two are equal then we have
