Answer: x + 4y - z
Step-by-step explanation:
Answer:
The third quartile is 56.45
Step-by-step explanation:
The given parameters are;
The first quartile, Q₁ = 30.8
The median or second quartile, Q₂ = 48.5
The mean, = 42.0
Coefficient of skewness = -0.38
The Bowley's coefficient of skewness (SK) is given as follows;
Plugging in the values, we have;
Which gives;
-0.38×(Q₃ - 30.8) = Q₃ + 30.8 - 2 × 48.5
11.704 - 0.38·Q₃ = Q₃ - 66.2
1.38·Q₃ = 11.704 + 66.2 = 77.904
Q₃ = 56.45
The third quartile = 56.45.
Answer:
15.839 rounded to the nearest tenth is 15.8. This is because when we round it to the nearest hundredth it becomes 15.84 and then to the tenth it becomes 15.8, since 4 is less than 5.
Iva got the correct answer and Lorraine's answer was incorrect. Lorraine did everything correct except 1 common mistake at the end. At the end of the problem, you have the equation 2x = 20. Instead of dividing by 2, it's possible that Lorraine mixed up the steps and divided by 10 on both sides to get x = 2. You're supposed to divide 2x by 2 and 20 by 2 to get a quotient of 10.

Answer:
The outcomes are given means
1H: the dice rolled into a 1, and the result of the coin flip is heads.
Then, the list will be:
1H, 2H, 3H, 4H, 5H, 6H, 1T, 2T, 3T, 4T, 5T, 6T
Where T means tails, H heads, and each number corresponds with one of the possible numbers of the dice.
You also can calculate the number of possible outcomes by multiplying the total outcomes of each experiment.
For the dice, we have 6 outcomes
for the coin, we have 2 outcomes.
From the coin and the dice at the same time, we have 6*2 = 12 outcomes, which coincides with the 12 possible outcomes listed above.
