a).no sugar=1. flour=3 1/2

B). sugar= 1 1/2. Flour= 5 1/4

c) your just simplifying to the smallest possible number

Step-by-step explanation:

1/2 doubled= 1 (1/2+1\2)

1 3/4= 7/4

7/4 doubled= 14/4=3 2/4= 3 1/2(1 1/3+1 1/3)

Ok so first lets do A. Her measurements are not correct the actual double is 1 cup of sugar and 3 1/2 cups of flour
Explanation:
2=2/1

Multiply 1/2 by 2/1 you get 1
Change 1 3/4 to an improper fraction and do the same
Multiply 7/4 by 2/1 you get 14/4 which equals 3 1/2

Now B. She would do the same thing but with three instead so

1/2x3/1= 3/2= 1 1/2
7/4x3/1= 21/4= 5 1/4

Now C the process for changing a mixed number into an improper fraction is you multiply the whole number by the denominator and add it to the numerator.

F(x)=x^3+10x^2+31x+30
Colt1911 [192]

The factors of the given polynomial will be ( x + 2 ), ( x + 5 ) and ( x + 3 ).

<h3>What is an expression?</h3>

Expression in maths is defined as the collection of the numbers variables and functions by using signs like addition, subtraction, multiplication and division.

The given expression will be solved as:-

f(x) = x³ + 10x² + 31x + 30

f(x) = ( x³ + 7x² + 10x + 3x² + 21x + 30

f(x) = ( x² + 7x + 10 ) ( (x + 3 )

f(x) = ( x²+ 5x + 2x + 10 ) ( x + 3 )

f(x) =[ x ( x+ 5 ) +2 ( x+ 5) ] ( x + 3 )

f(x) = ( x + 5 ) ( x + 2 ) ( x + 3 )

Therefore factors of the given polynomial will be ( x + 2 ), ( x + 5 ) and ( x + 3 ).

When Alice spends the day with the babysitter, there is a 0.6 probability that she turns on the TV and watches a show. Her littl
slava [35]

Answer:

a) There is a 48% probability that both Alice and Betty watch TV tomorrow.

b) There is a 48% probability that Betty watches TV tomorrow.

c) There is a 12% probability that only Alice watches TV tomorrow.

Step-by-step explanation:

We have these following probabilities:

A 60% probability that Alice watches TV.

If Alice watches TV, an 80% probability Betty watches TV.

If Alice does not watch TV, a 0% probability that Betty watches TV, since she cannot turn the TV on by herself.

a) What is the probability that both Alice and Betty watch TV tomorrow?

Alice watches 60% of the time. Betty watches in 80% of the time Alice watches. So:

P = 0.6*0.8 = 0.48

There is a 48% probability that both Alice and Betty watch TV tomorrow.

b) What is the probability that Betty watches TV tomorrow?

Since Betty only watches when Alice watches(80% of the time), this probability is the same as the probability of both of them watching. So

P = 0.6*0.8 = 0.48

There is a 48% probability that Betty watches TV tomorrow.

c) What is the probability that only Alice watches TV tomorrow?

There is a 60% probability that Alice watches TV tomorrow. If she watches, there is an 80% probability that Betty watches and a 20% probability she does not watch.

So

P = 0.6*0.2 = 0.12

There is a 12% probability that only Alice watches TV tomorrow.
