A professor graded the final exams and found that the mean score was 70 points. Which of the following can you conclude?A- All of the above.

B- The median score was 70 points.

C- 50% of the students scored below 70 points.

D- This would be a normal distribution.

Answers

Answer 1

Answer:

Answer: C) 50% of the students scored below 70%

Step-by-step explanation:

Mean is the average. To find the mean (aka average) you add up all of the scores and divide by the number of tests.

B) The mean can be 70 without any test scoring 70% so B is not true.

A) Since B is not true, then A is not a valid option.

D) We don't know any of the other data so don't know if it is skewed left, skewed right, or normal. Therefore, option D is not true.

C) If the average is 70%, then half received grades above that score and half received grades below that score. So, option C is TRUE!

The table represents a linear function. What is the slope of the function?

Answers

Slope is the change in y over the change in x.

Using the first and last value, the change in x would be the change from -4 to 4 which is 8

The change y y would be the change from -16 to 24 which is 40

The slope would be 40/8 which reduces to 5

The answer is 5

40% of the groups budget was spent on activities. If $64,000 was spent on the activities, what was the full budget? solve with the aid of a diagram. State what type of problem this is. if it's division, which type? Explain your reasoning, not just by using an equation.

Answers

Answer:

The full budget has a total value of $160,000

Step-by-step explanation:

This is a simple ratio problem and can be solved using the Rule of Three property. The Rule of Three is used to compare two ratios and find the missing part. In this case the ratios would be the following.

$(64,000)/(40 percent) = (x)/(100 percent)$

$(64,000 * 100 percent)/(40 percent) = \frac{x}$

$(6,400,000)/(40 percent) = \frac{x}$

$160,000= \frac{x}$

So now we know that 100% (The full budget) has a total value of $160,000.
