Step-by-step explanation:
Select the correct answer from each drop-down menu.
We solve using z score formula
z-score is z = (x-μ)/σ, where x is the raw score, μ is the population mean, and σ is the population standard deviation.
The average time taken to complete a test follows normal probability distribution with a mean of 70 minutes and a standard deviation of 25 minutes.
a) The probability of a randomly selected student completing the test in 45 minutes or less is approximately equal to %.
z = 45 - 70/25
b) The probability of a randomly selected student completing the test in 95 minutes is %.
z = 95 - 70/25
Answer:
The mathematical symbols that are filled in between the numbers to make it a true equation are the multiplication signs.
Step-by-step explanation:
This questions implies that there is a need to fill in mathematical symbols that will this a true a equation.
A true equation can be described as situation whereby there the same values on the either sides of the equal sign "=". For instance, 5 + 1 = 6 is a true equation. Also, 4 * 2 = 8 is a true equation.
As regards this question, the mathematical symbols that are filled in between the numbers to make it a true equation are the multiplication signs. When the multiplication signs are filled in between the numbers, we have the following true equation:
2802 * 1811 * 123 * 441 * 3633 * 1/3 * 32^2 * 205 = 69,972,637,305,761,000,000
The intersections of lines l and m is B as that is the only point where those two lines meet
You will have to cross multiply and also distribute the fractions like this:
2/3 of 3/8 times 16
so 3/8 times 16 is 6
Now take 2/3 of 6 and youll end up with 4! :)
