In art class, Ms. Ward has students draw a tile at random from a bag of tiles. Each tile has a shape drawn on it, and students m

ust center their art project around the shape they draw. If the bag contains a rectangle, rhombus, regular hexagon, trapezoid, and isosceles triangle, what is the probability that a student draws a shape with all sides congruent?

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

5x + 2y=7<br> - 2x + 6y=9
ollegr [7]

Answer:

x = \frac{12}{17} or 0.706

y = \frac{59}{34} or 1.735

Step-by-step explanation:

5x + 2y=7    ----->(eq 1)

- 2x + 6y=9 ----->(eq 2)

Multiply (eq 1) with 3

3×(5x + 2y) = 3×7  

15x + 6y = 21  ----->(eq 3)

substract (eq 3) from (eq 2)

- 2x + 6y - (15x + 6y) = 9-21

- 2x + 6y - 15x - 6y = 9-21

- 2x - 15x + 6y - 6y = 9-21

-17x = -12

x = -12 ÷ -17

x = \frac{12}{17}

put x = \frac{12}{17} in (eq 1)

5*\frac{12}{17} + 2y = 7

2y = 7- 5*\frac{12}{17}

2y = \frac{7*17 - 60}{17}

2y = \frac{119- 60}{17}

2y = \frac{59}{17}

y = \frac{59}{17*2}

y = \frac{59}{34}
