In a certain city, 27% of the families have a MasterCard, 19% have an American Express card, and 22% have a Visa card. Nine perc

Natasha2012 [34]

Answer:

35%

Step-by-step explanation:

Data provided in the question:

P(Master card) = 27% = 0.27

P(American express card) = 19% = 0.19

P( Visa card ) = 22% = 0.22

P( Master and American express card ) = 9% = 0.09

P( Visa and master card ) = 14% = 0.14

P( American express and visa card ) = 6% = 0.06

Now,

The probability of selecting a family that has either a Visa card or an American Express card

= P( Visa card ) + P( American express card ) - P( Visa and American express card )

= 0.22 + 0.19 - 0.06

= 0.35

or

= 0.35 × 100% = 35%

PLEASE HELP ME WITH THIS I WILL MARK BRAINLIEST!! Classify each system of equations as having a single solution, no solution, or

Wewaii [24]

Answer:

see the explanation

see the attached figure

Step-by-step explanation:

Part 1) we have

$y=11-2x$ ----> equation A

$4x-y=7$

Isolate the variable y

$y=4x-7$ ----> equation B

Compare the slope of both lines

The slopes are different

That means

The lines intersect at one point

therefore

The system has one solution

Part 2) we have

$x=12-3y$

isolate the variable y

$y=-(1/3)x+4$ -----> equation A

$3x+9y=24$

isolate the variable y

$y=-(1/3)x+(8/3)$ ----> equation B

Compare equation A and equation B

The slopes are equal

The y-intercept are different

That means

we have parallel lines with different y-intercept

so

The lines don't intersect

therefore

The system has no solution

Part 3) we have

$2x+y=7$

isolate the variable y

$y=-2x+7$ -----> equation A

$-6x=3y-21$

isolate the variable y

$y=-2x+7$ ----> equation B

Compare equation A and equation B

The equations are identical

That means

Is the same line

so

The system has infinitely solutions

Part 4) we have

$x+y=15$

isolate the variable y

$y=-x+15$ -----> equation A

$2x-y=15$

isolate the variable y

$y=2x-15$ ----> equation B

Compare the slope of both lines

The slopes are different

That means

The lines intersect at one point

therefore

The system has one solution

Part 5) we have

$2x+y=7$

isolate the variable y

$y=-2x+7$ -----> equation A

$-4x=2y+14$

isolate the variable y

$y=2x-7$ ----> equation B

Compare the slope of both lines

The slopes are different

That means

The lines intersect at one point

therefore

The system has one solution

Part 6) we have

$x+4y=6$

isolate the variable y

$y=-0.25x+1.5$ -----> equation A

$2x=12-8y$

isolate the variable y

$y=-0.25x-1.5$ ----> equation B

Compare equation A and equation B

The slopes are equal

The y-intercept are different

That means

we have parallel lines with different y-intercept

so

The lines don't intersect

therefore

The system has no solution
