75% of all undergraduates are in the College, 10% are in Engineering, 8% are in Commerce, 4% are in Nursing, and 3% are in Archi

Hunter-Best [27]

Answer:

the probability a randomly selected student is a third-year that they are in the College is 0.1743

Step-by-step explanation:

Given information

75% College = C = 0.75

10% are in Engineering, Eng = 0.1

8% are in Commerce, Com = 0.08

4% are in Nursing, Nurs = 0.04

3% are in Architecture, Arch = 0.03

21% Third year student = S = 0.21

21% in the College = 0.21

25% in Engineering = 0.25

49% in Commerce = 0.49

57% in Nursing = 0.57

33% in Architecture = 0.33

P(SlC) = 0.75 x 0.21 = 0.1575 is the probability of third year student in college

P(SlEng) = 0.1 x 0.25 = 0.025

P(SlCom) = 0.08 x 0.49 = 0.0392

P(SlNurs) = 0.04 x 0.57 = 0.0288

P(SlArch) = 0.03 x 0.33 = 0.0099

P(S) = P(SlEng) + P(SlCom) + P(SlNurs) +P(SlArch)

= 1- (0.025 + 0.0392 + 0.0288 + 0.0099)

= 0.9031

The probability of third year student in college is

P(ClS) = P(SlC) / P(S)

= 0.1575 / 0.9031

= 0.1743

What is the y-coordinate for the solution to the system of equations?<br><br> {y=1/2x−4<br> {y=−2x+1

katovenus [111]

Answer:

y = -3

Step-by-step explanation:

{y = x/2 - 4

y = 1 - 2 x

Substitute y = x/2 - 4 into the second equation:

{y = x/2 - 4

x/2 - 4 = 1 - 2 x

In the second equation, look to solve for x:

{y = x/2 - 4

x/2 - 4 = 1 - 2 x

Add 2 x + 4 to both sides:

{y = x/2 - 4

(5 x)/2 = 5

Multiply both sides by 2/5:

{y = x/2 - 4

x = 2

Substitute x = 2 into the first equation:

{y = -3

x = 2

Collect results in alphabetical order:

Answer:

{x = 2

y = -3

A café sells a regular cup of coffee for $1 and

Over [174]

if x is a regular cip of coffee and y is a large cup of coffee. the first part of the equation being the number of the cups of coffee and the second part expressing the price. using the method of substitution we solve for x in the first equation

x= 5-y

and then we solve for y

then we substitute the value found in the easiest equation which would be the first one and we solve for x

x + 2 = 5

x + 2 - 2 = 5 - 2

x = 3

so its 3 regular cups and 2 large
