Jonathan, a college business student wants to study how many pages of notes fellow classmates took during a semester for a finan

ce class. Past data reveals that pages of notes for a finance college class has a mean of 95 , with standard deviation 25 pages. He plans to take a random sample of 30 such college students and will calculate the mean pages of notes they take to compare to the known pages of notes students take for a finance college class. For these values, the mean and standard deviation of the sampling distribution of sample means for a sample of size 30 are: μx¯=95 and σx¯=2530√=4.6. What is the probability that the sample mean for a sample of size 30 will be at least 99? You may use a calculator or the portion of the z-table given below.

Step-by-step explanation:

The sum of the interior angles of a triangle is equal to 180° so we can write

y + 2y + 3y = 180° \Rightarrow 6y = 180°

Solving for y, we get

y = 30°

So the other two angles of the triangle are

2y = 2(30°) = 60°

and

3y = 3(30°) =90°

A video game that usually costs $30.65 is marked down 60%. Kelvin determined that the new price of the game would be $18.39. Loo
sladkih [1.3K]
The error.....Kelvin just figured the 60% markdown cost...not the final price

the final price would be : 30.65 - 0.60(30.65) = 30.65 - 18.39 = 12.26
so 12.26 is the final price

or another way to do this is : if it is marked down 60%, then u r actually paying 40%......0.40(30.65) = 12.26
