1. Name an example of a real-world data set, not yet mentioned in the course, where you would typically expect to see a normal d

istribution. Be sure to describe what the labels would be for the horizontal and vertical axis of the display. Then explain why you would expect a normal distribution. What range of data values would you expect to represent 1 standard deviation from the mean? (15 points; 10 for your answer, 5 for response to others' comments.)​

Answer:

1.The heights of students in a class, for example, would have a normal distribution. We expect a few students to be extremely tall and a few to be extremely short, but the majority will be in the middle. On the x-axis, we'll have heights, and on the y-axis, we'll have the frequency of the number of students with heights. According to the empirical rule, 68 percent of the data could fall within one standard deviation of the mean.

vova2212 [387]

Answer:

5700

Step-by-step explanation:

step 1 Address the formula, input parameters & values.

Input parameters & values:

The number series 2, 4, 6, 8, 10, 12, .  .  .  .  , 150.

The first term a = 2

The common difference d = 2

Total number of terms n = 75

step 2 apply the input parameter values in the AP formula

Sum = n/2 x (a + Tn)

= 75/2 x (2 + 150)

= (75 x 152)/ 2

= 11400/2

2 + 4 + 6 + 8 + 10 + 12 + .  .  .  .   + 150 = 5700

Therefore, 5700 is the sum of first 75 even numbers.

Harman [31]

Answer:

50 cm squared.

Step-by-step explanation:

All you need to do is multiply the 5 (which is the height) times 10 (which is the base).

The volume of a parallelogram is base times height.

so, 5 times 10 = 50

Please help me <br> Find f(-4)
Katyanochek1 [597]
As x < 3, you would use the equation x^{2} -5
Plus in -4 for X and you would get (-4)^{2} -5
(-4)^{2} is equal to 16.
16-5=11&#10;
f(-4)=11
