Answer:
0.200
Step-by-step explanation:
The probability of obtaining a 3, in one roll of a fair die is 1/6.
Now, we have 5 rolls.
We now want to know the probability of a 3 showing up in at least one of the rolls.
This simply mean, we add the probabilities of three showing one time plus probability of three showing in 2 of the rolls e.t.c
This means we can have 3 showing up to 5 times.
We add the probabilities as follows:
(1/6) + (1/6)^2 + (1/6)^3 + (1/6)^4 + (1/6)^5 = 0.199974 = 0.200
Answer:
x = (4r +3)/(r +2)
Step-by-step explanation:
Collect x terms, then divide by the coefficient of x.
x(r +2) = 4r +3
x = (4r +3)/(r +2)
Answer:
The coordinates of the police car is (12,8)
(C) is correct option
Step-by-step explanation:
Given that,
If a police car is parked on the side of the highway, exactly four-fifths of the distance from Exit A to Exit B.
According to figure,
Suppose, The points A and B are (2,3) and (4,4)
We need to find the coordinates of the police car
Using section formula for external point
For x,
Put the value into the formula
For y,
Put the value into the formula
Hence, The coordinates of the police car is (12,8)
(C) is correct option.
Answer:
The values you need to know to create a box plot are:
lower quartile ⇒ 2nd
maximum value ⇒ 3rd
median ⇒ 5th
Step-by-step explanation:
Box plots is a type of graph that can help to organize data.
To graph a box plot the following data points must be calculated:
- The minimum value ⇒ least value
- The first quartile ⇒ lower quartile (the middle of the data before the median)
- The median ⇒ the middle value of the arranged data from smallest to greatest
- The third quartile ⇒ upper quartile (the middle of the data after the median)
- The maximum value ⇒ greatest value
After you make the box plot graph, you can display and compare distributions of data
Let us answer the question
The values you need to know to create a box plot are:
lower quartile ⇒ 2nd
maximum value ⇒ 3rd
median ⇒ 5th
