In a class in which the final course grade depends entirely on the average of four equally weighted 100-point tests, Alice has s

IgorC [24]

Answer:

between 62 and 98.

Explanation:

This question can be solved faily easy:

We denote "B" as the value average of the four test values for B score (between 80 - 89) and "X" as the score on the 4th test so to find the range of values that Alice needs to score in the 4th test we only have to replace in the next formula:

$B=\frac{94 + 77 + 87 + X}{4}$

$X=4*B-94-77-87$

We reformulate the equation in function of B

We have the next range of values for "B" (80, 81, 82, 83, 84, 85, 86, 87, 88, 89), we replace those values in the formula and operate to get the range of values we need to score in the 4th test.

$X=4*80-94-77-87=62$

$X=4*81-94-77-87=66$

$X=4*82-94-77-87=70$

$X=4*83-94-77-87=74$

$X=4*84-94-77-87=78$

$X=4*85-94-77-87=82$

$X=4*86-94-77-87=86$

$X=4*87-94-77-87=90$

$X=4*88-94-77-87=94$

$X=4*89-94-77-87=98$

As we can see for Alice to get a B for the semester she needs to score on the 4th test a score between 62 and 98 points.

Seeking niche audiences, as opposed to broadcasting's traditional audience-building concept.

Len [333]

Answer:

Narrowcasting

Explanation:

Based on the information provided within the question the term being defined in this statement is called Narrowcasting. This term (also known as niche marketing) is the process that media organizations focus on by targeting small specific groups (niches), individuals or audiences, instead of just marketing something into the bigger and wider mainstream audience. This is usually done in order to broadcast a certain message to the people that will actually care about that message.

Embryonic stem cells derived from blastocysts are pluripotent, and therefore useful in stem cell research because they ________.

Elanso [62]

Answer:

The answer is: They not only serve for Regenerative Medicine, but also for the "screening" of new drugs, and some other things.

Explanation:

Currently, studies in regenerative medicine are aimed at research and knowledge of induced pluripotent cells (iPSCs). For some, they are the cells called to take over from embryonic stem cells (ESCs), which until recently were the main objective of research in this field of biomedicine.

Since the first cultures of mouse embryonic cells derived from blastocysts were obtained in 1981, the foundations were laid for the development of the necessary methodologies that would lead later to generate human embryonic cells with characteristics similar to those of the mouse.

In addition to their interest in Regenerative Medicine, these types of cells are a tool of great value for the "screening" of new drugs, as well as a model to study the etiology of diseases that originate during the embryonic stage, and to study processes that occur during human embryonic development .

The answer is: They not only serve for Regenerative Medicine, but also for the "screening" of new drugs, and some other things.
