The outcome of A. Sadera and Scot W. McNaryshows that A significant differences exist between learning environments along with the students in a scenario of blended courses having the lowest success.
<h3>What is the study about?</h3>
The aim of the paper was to show a research study that compared student success in a Developmental Math course offered in three different learning environments which are said to be (online, blended, and face-to-face).
Note that the study also show that the outcome of A. Sadera and Scot W. McNary was that there was a significant differences exist between learning environments along with the students in a scenario of blended courses having the lowest success.

It is is super warm and it will heat up crating climat change
The number of ways the skaters can finish the competition is 40,320 ways
The different ways 3 of the skaters finish first, second and third is 56 ways
Given the following
- Number of skaters featured = 8 skaters
If the skaters finish the competition, the number of different ways the skaters finish the competition is expressed as:
8! = 8*7*6*5*4*3*2
8! = 56*30*24
8! = 40,320.
The number of ways the skaters can finish the competition is 40,320 ways
If 3 of the skaters finish first, second and third, the number of ways this can be done is given as:
8C3 = 8!/(8-3)!3!
8C3 = 8!/5!3!
8C3 = 8*7*6*5!/5!3!
8C3 = 56 ways
Hence the different ways 3 of the skaters finish first, second and third is 56 ways

If the second mammogram also had a positive result, the probability that the woman has cancer becomes d) 0.52.
<h3>What is the probability the woman has cancer?</h3>
The probability that the woman has cancer given a positive second result can be found as:
= (Probability of having cancer and a positive result) / (Probability of a positive result regardless of cancer status)
Solving gives:
= (0.12 x 0.78) / ( (0.12 x 0.78) + (0.88 x 0.1))
= 0.0936 / (0.0936 + 0.088)
= 0.52
Full question information is:
- American Cancer Society estimates that about 1.7% of women have breast cancer.
- Susan G. Komen For The Cure Foundation states that mammography correctly identifies about 78% of women who truly have breast cancer.
- An article published in 2003 suggests that up to 10% of all mammograms result in false positives for patients who do not have cancer.
