Answer:

D

y-5=3(x+1)

Step-by-step explanation:

We can see that the question is asking for the Point-Slope Form;

y-y_{1} =m(x-x_{1})

The points go into the equation for y_{1} and x_{1}

y-5=m[x-(-1)]

M would be the slope;

y-5=3[x-(-1)]

Which basically is:

y-5=3(x+1)

A student entering a doctoral program in educational psychology is required to select courses from the list of courses provided
SVEN [57.7K]

A) The possible three-course selections are as shown below.

B) The likelihood of selecting the combinations is 0.1 since there are 10 combinations in total.

<h3>How to solve probability combinations?</h3>

A combination operator can be used when we need to find the number of ways to select "k" items from a set of "n" items. It is also called a 'choose' operator where it is read as 'n choose k' and is represented and calculated as given below

From the choices given, there are 5 courses which are given below:

EPR 605

EPR 643

EPR 648

EPR 674

EPR 681

We need to find the combinations of 3 of these given 5 courses, which are given below (omitting the course code, EPR):

605-643-648

605-643-674

605-643-681

605-648-674

605-648-681

605-674-681

643-648-674

643-648-681

643-674-681

648-674-681

10 of the given choices of combinations are possible since they do not include a repeated course number.

The likelihood of selecting the combination of EPR 681, EPR 648, and EPR 605 is 0.1 since there are 10 combinations in total.

Complete question is;

A student entering a doctoral program in educational psychology is required to select three courses from the list of courses provided as part of his or her program. List all possible three-course selections. Comment on the likelihood that EPR 681, EPR 648, and EPR 605 will be selected. Select all the possible three-course selections below.

A. 648, 674, 605

B. 681, 648, 605

C. 681, 674, 605

D. 681, 681, 648

E. 674, 643, 674

F. 674, 605, 643

G. 681, 648, 674

H. 681, 681

I. 681, 648, 643

J. 648, 605, 643

K. 648, 674, 643

L. 681, 605, 643

M. 643, 694, 643

N. 681, 674, 643

Can someone please help me with this? ​
geniusboy [140]

Answer: B and D

Step-by-step explanation:

First, solve the terms inside of the parenthesis. As a general rule, whenever you multiply two terms that have the same base, you can add their exponents.

Applying this rule, the base in the problem is 6, and the exponents are 3 and -4. The sum of 3 and -4 leaves -1. Therefore, this is one of our solutions:

(6^-^1)^-^3

When you have an exponential term raised to another exponent, you can simply multiply the exponents. In the previous solution given above, multiply -1 and -3 to get 3. Therefore our second solution is:

6^3
