Answer:
a) This is a continuous random variable because the set of possible values is an interval.
b) Height = 0.5
Graph attached.
c) P(Y≤1) = 0.5
Step-by-step explanation:
a) If the density curve of the outcomes has a constant height, we have a uniform distribution for values between 0 and 2 (outside this range, the density function has a value of 0).
This function is continous and has a value for each real number. The set of possible values has a is an interval between 0 and 2, all with equal probability (the ones that are otuside this interval have 0 probability, so they are not possible values).
b) The height is calculated so that the total area under the density curve has to be equal to 1.
Then, we have to calculate the integral between 0 and 2 of the density function:
The height is H=0.5
(Graph attached)
c) The probability can be calculated by integrating the density function (which is equal to the area under the curve) between 0 and 1, or using the graph.
With the graph, we see that the area is equal to the height (0.5) by the width of the interval (1), so the total area is 0.5 x 1 = 0.5.
The probability P(Y≤1) is equal to 0.5.
To figure this out, you have to figure out what Donovan scored.
Just divide his score (39 ÷ 50) and get 0.78.
Since we already knew this, we can figure out Marci's score. Since she score 88%, we can assume she scored somewhere in the 40's.
Once you figure out what her score was out of 50, divide it.
Your equation should look like this: 44 ÷ 50 = 0.88
This means that Marci answered 44 questions out of 50 questions correctly. (44/50)
Dear Mgreeneyesd3, the ratios of children to teacher are proportional. 6/24=1/4, so if we do cross products, then we get 24=24.
