Prob (8) = 4/52 = 1/13
Prob(Queen) = 4/52 = 1/13
Prob ( 8 then a queen) = 1/13 * 1/13 = 1/169 answer
The probabilities are multiplied beause the 2 events are independent
Answer:
(1,5) is your answer
Step-by-step explanation:
You would have to divide the
2 and 10 by 2 and you would get (1,5)

Answer: One sample z test for means
Step-by-step explanation:
From the information given, the sample size is large. It is greater than 30. Again, the population standard deviation is given. This means that the test statistic would be the z score which is determined by the formula
z = (x - µ)/σ
Where
x = sample mean
µ = population mean
σ = population standard deviation
The probability value would be determined from the normal distribution table.
Therefore, the hypothesis test that should be used is
One sample z test for means
To write an equation to represent a given information, the equations are to
expresses the information conveyed in the situation.
The two equations that represent the given information are;
- <u>5.6·x + 4·y = 133.6</u>
Reasons:
The given information are;
Mass of the large boxes = 5.6 kg
Mass of the small boxes = 4 kg
Number of boxes delivered = 25 boxes
Total mass of the boxes delivered = 133.6 kg
Number of the 5.6 kg box delivered = x
Number of the 4 kg boxes delivered = y
Required:
To form two equations in terms of <em>x</em> and <em>y</em> to represent the situation.
Solution:
The two equations are;
- The number of boxes delivered = <u>x + y </u><u>= 25</u>
- Total weight of the boxes delivered = <u>5.6·x + 4·y </u><u>= 133.6</u>
<em>Solving the above equations with a graphing calculator gives;</em>
