Jamal has the following choices for his pizza: white sauce or red sauce; white cheese or yellow cheese; and mushrooms, pepperoni or sausage. What is the probability that he creates a pizza that has red sauce and mushrooms?

Answers

Answer 1

Answer:

The probability that he creates a pizza that has red sauce and mushrooms are:

$(1)/(6)$

Step-by-step explanation:

Jamal has the following choices for his pizza:

White sauce or red sauce; white cheese or yellow cheese; and mushrooms, pepperoni or sausage.

Let A denote the event of choosing a red sauce.

and B denote the event of choosing a mushroom.

Let P denote the probability of an event.

Now we know that event A and event B are independent.

We are asked to find:

P(A∩B)

Since the two events are independent.

Hence,

$P(A\bigcap B)=P(A)* P(B)$

$P(A)=(1)/(2)$

( Since out of 2 choices i.e. white sauce or red sauce , we have to choose red sauce)

and

$P(B)=(1)/(3)$

( Since, out of 3 choices i.e. mushrooms, pepperoni or sausage we have to choose mushroom)

Hence, the answer is:

$P(A\bigcap B)=(1)/(2)* (1)/(3)$

i.e.

$P(A\bigcap B)=(1)/(6)$

Answer 2

Answer: the probability of jamal making a pizza with red sauce and mushrooms is 2/7

Answers

Answer:

Option 1 $-2a+2c$

Step-by-step explanation:

To find : Take $4a - 3b + 2c$ from $2a - 3b + 4c$ .

Solution :

The equation $4a - 3b + 2c$ ....(1)

$2a - 3b + 4c$ ....(2)

Taking (1) from (2) means subtracting equitation (2) from (1),

i.e $=(2a - 3b + 4c)-(4a - 3b + 2c)$

$=2a - 3b + 4c-4a+3b-2c$

$=-2a+2c$

So, Taking $4a - 3b + 2c$ from $2a - 3b + 4c$ is $-2a+2c$

Therefore, Option 1 is correct.

2a-3b+4c-(4a-3b+2c)
=2a-3b+4c-4a+3b-2c
=-2a+2c

Answers

P1=2x+2y=30

after modify them

P2=2*3x+2*4y=102

6x+8y=102

2x+2y=30 / * (-3)

-6x-6y= -90

6x+8y=102

we must add the 2 expressions

/ 8y-6y=102-90

2y=12

y=12:2

y=6

2*x+2*y=30

2x+2*6=30

2x+12=30

2x=30-12

2x=18

x=18:2

x=9

Isabella saved $15,000 and bought a car that cost $12,700. The insurance for the carwill cost $600 per year. How many full years will Isabella be able to pay for car
insurance with her remaining savings?

Answers

Answer:

3 full years

Step-by-step explanation:

First figure how much she has left over.

15,000-12700=2300

Each year insurance costs $600.

$2300/600 = 3.8

She almost has 4 years but can't quite pay the 4th year so the answer is 3 years.
