A special deck of cards has 5 red cards, and 4 purple cards. The red cards are numbered 1, 2, 3, 4, and 5. The purple cards are

True [87]

Answer:

a. 9

b. 4/9 or 0.444

Step-by-step explanation:

R=red card={R1,R2,R3,R4,R5}

E=even card={R2,R4,P2,P4}

n(R)=5

n(E)=4

There 5 red and 4 purple card so, the sample space would be

Sample space=S={R1,R2,R3,R4,R5,P1,P2,P3,P4}

number of elements in sample space=n(S)=9

So, the number of elements in the sample space are 9.

P(E)=n(E)/n(S)

P(E)=4/9 or 0.444

Thus, the probability of an even numbered card is 0.444.

Una diseñadora de modas que confecciona trajes de noche, tarda 3 horas en cortar y 2 horas en coser cada vestido de fiesta. Para

ella [17]

For this case we define the following variables:

x: Number of party dresses

y: Number of suits

You have 30 hours per week to cut, that is, the first equation is given by:

$3x + 3y = 30\\$

It is also known that 25 hours per week are available for sewing, that is:

$2x + 3y = 25\\$

It has a system of two equations with two unknowns, solving we have:

$3x + 3y = 30\\\\2x + 3y = 25\\$

Multiplying the second equation by -1:

$3x + 3y = 30\\\\-2x-3y = -25\\$

Adding up:

$x + 0 = 5\\\\x = 5\\$

Substituting x in the first equation:

$3 * 5 + 3y = 30\\\\15 + 3y = 30\\$

Clearing and:

$3y = 30-15\\\\3y = 15\\$

$y = \frac{15}{3}\\\\y = 5\\$

Thus, per week, the designer can produce 5 party dresses and 5 suits working at her maximum capacity.

Answer:

5 Party dresses

5 Suits
