What is the probability that the selected consumer is 35–55 years old or likes crunchicles?

Tju [1.3M]

The probability that the selected consumer is 35–55 years old or likes Crunchicles is 0.444.

Number of people who liked Crunchicles = 121

Number of people who are 35 - 55 years of age = 120

Number of people who are 35-55 years of age or like crunchicles = 121 + 120 - 19

The probability that the selected consumer is 35–55 years old or likes Crunchicles = 222/500 = 0.444.

4. If u = {1,2,3,....10) A = { odd numbers up to 9} B = {numbers less than 7). Write out the members of the following sets: (i)

icang [17]

Answer:

i. {1,2,3,4,5,6,7,9}

ii. {1,3,5}

iii. {1,2,3,4,5,6,8,10}

Step-by-step explanation:

U= {1,2,3,4,5,6,7,8,9,10}

A= {1,3,5,7,9}

B= {1,2,3,4,5,6}

A U B = {1,2,3,4,5,6,7,9}

A n B = { 1,3,5}

A (prime) U B =

A(prime)= {2,4,6,8,10}

Therefore A(prime)= {1,2,3,4,5,6,8,10}

ryzh [129]

Answer:

Step-by-step explanation:

Hello,

$\dfrac{p}{q}*\dfrac{q}{p}=1=(2x+2)(2-x)\\\\ 4x-2x^2+4-2x=1\\\\ -2x^2+2x+4-1=0\\\\ -2x^2+2x+3=0\\\\$

There are two solutions

$\Delta=b^2-4ac=2^2+4*2*3=4+24=28=7*4\\x_1=\dfrac{-2+\sqrt{7*4}}{-4}=\dfrac{-2+2\sqrt{7}}{-4}=\dfrac{1-\sqrt{7}}{2}\\x_2=\dfrac{1+\sqrt{7}}{2}\\$

Hope this helps
