x-6=y
This is how you find Jenny's age, by subtracting 6 years from Sue's age.
Answer: Correct answer is not listed, is there an option for D? Or was the question worded wrong?
The correct answer to the question you asked would be $716.50
Step-by-step explanation:
17 hours × $24.50 = $416.50
But it says she usually earns $300, and this month she worked 17 extra hours.
So to me, that sounds like you would add her usual earnings to her extra earnings to get the total for the month.
$300 + $416.50 = $716.50
However, if there is not an option for this amount, then the question was just worded a little off and the next best answer would be $416.50 which is the amount of extra income she made while working those extra 17 hours.
Answer:
1 /4
Step-by-step explanation:
Given that :
Let :
P(S) = probability of drawing a spade
Odds in favor of drawing a spade = 1:3 ; this could be interpreted as :
P(drawing a spade)/P(not drawing a spade) = 1:3
P(S) / P(S') = 1/ 3
P(S') = 1 - P(S)
P(S) / (1 - P(S)) = 1 / 3
Cross multiply :
3P(S) = 1 - P(S)
Collect like terms
3P(S) + P(S) = 1
4P(S) = 1
P(S) = 1/4
Hence, probability ratio of drawing a spade P(S) = 1/4
The better statistics which can be used to compare the given distributions are mean and standard deviation.
<h3>What is a z-core?</h3>
A z-core is also referred to as a standard score and it can be defined as a statistical measure of the distance between a data point (raw score) and the mean, especially when standard deviation units are used.
In Mathematics, z-scores can either be negative or positive and it is generally calculated by using this formula:

<u>Where:</u>
- x is the observed data or sample mean.
is the standard deviation.
In conclusion, the better statistics which can be used to compare the given distributions are mean and standard deviation.
