Consider functions f and g.

MissTica

A function assigns the values. The sum of the two function will be equal to 3[√(x-3) + 5].

<h3>What is a Function?</h3>

A function assigns the value of each element of one set to the other specific element of another set.

Given f(x)=√(x-3) and g(x)=[√(4x-12)]+15, therefore, the sum of the two function will be written as,

$(f+g)(x)= \sqrt{x-3} + \sqrt{4x-12}+15\\\\$

$= \sqrt{x-3} + \sqrt{4(x-3)}+3(5)\\\\ = \sqrt{x-3} + 2\sqrt{(x-3)}+3(5)\\\\= 3\sqrt{(x-3)}+3(5)\\\\ = 3[\sqrt{(x-3)}+5]$

Hence, the sum of the two function will be equal to 3[√(x-3) + 5].

jeka57 [31]

Answer:

a. 3/4

b. 1/2

c. 5/6

Step-by-step explanation:

From the question, We are given that:

4 different colours, 3 different font types, 5 sizes, 3 images, 5 text phrases.

If event A is the event that the design color is red, then:

P(A) = 1/4

P(A') = 1 - 1/4 = 3/4.

If event B is the event that the font size is not the smallest one, then:

P(B) = 2/3

P(B')= 1 - 2/3 = 1/3.

P(AnB) = 1/4 * 2/3 = 2/12=1/6

P(AnB')=1/4 * 1/3 = 1/12

P(A'nB') = 3/4 * 1/3=1/4

Solving the questions,

a. P(AuB) = P(A) + P(B) - P(AnB)

P(AuB) =(1/4) + (2/3) -(1/6)

P(AuB) = 9/12

P(AuB) = 3/4

b. P(AuB') = P(A) + P(B') - P(AnB')

P(AuB') = 1/4 + 1/3 - 1/12

P(AuB') = 6/12

P(AuB') = 1/2

c. P(A'uB') = P(A') + P(B') - P(A'nB')

P(A'uB') = 3/4 + 1/3 - 1/4

P(A'uB') = 10/12

P(A'uB')=5/6

Jake tossed a paper cup 50 times and recorded how it landed. The table shows the results:

Varvara68 [4.7K]

P(landing open side up)= 1/50
P(landing closed side up)=5/50=1/10
P(landing on its side)= 44/50=22/25
