A distribution is positively skewed if which of these statements is true about the density curve that represents it?A. The left side is a mirror reflection of the right side.
B. The left tail is equal in length to the right tail.
C. The left tail is longer than the right.
D. The right tail is longer than the left.

Answers

The right answer for the question that is being asked and shown above is that: "D. The right tail is longer than the left." Positively skewed distribution is asymmetrical and points in the positive direction. So, the tail on the right is longer than that of the left.

In a factory, an assembly line can manufacture 39 widgets per second. In another factory, 6 widgets are combined to make 1 whoozit. Approximately how many days must the widget assembly line run to produce 3,500,000 whoozits?A.4 days
B.6 days
C.374 days
D.9479 days

Answers

Given:
39 widgets per seconds
6 widgets to make 1 whoozit

3,500,000 whoozits * 6 widgets/whoozits = 21,000,000 widgets
21,000,000 widgets / 39 widgets/sec = 538,461.54 seconds

1 day = 24 hours
1 hour = 60 minutes
1 minutes = 60 seconds
1 hour = 3600 seconds

3,600 seconds * 24 hrs = 86,400 seconds 
538,461.54 seconds / 86,400 seconds per day = 6.23 days.

B. 6 days.

Which graphs represent functions?

Answers

Answer:

A. Only graph B and D

Step-by-step explanation:

Hi, to answer this question we have to analyze the options given:

A function has only one output value (y) for each input value.(x)

In other words, If we draw a vertical line (anywhere on the graph) that intersects the graph in two points or more, then the graph does not represent a function because that x value has more than one output(y).

So, the correct option is:

A. Only graph B and D

What is one quarter added to three eights answer

Answers

1/4 + 3/8 = 5/8

You always have to change the denominators (which are the bottom parts of the fraction) to be the same. To make it simple you do 8 as the denominators, 2 × 4= 8.
Now all you have to do is add 2/8 + 3/8= 5/8
Easy as pie! Hope I helped you :)
You have to make the denominators the same so 1/4 and 3/8, times 1 and 4 by 2 so intead of 1/4 you have 2/8 and 2/8 + 3/8 which makes 5/8, which is a prime number so cannot be simplified
