Greetings!

11/4=2.75
To make 11 dozen cookies, you would need to make 2.75 times the recipe.
Therefore, you will need 2.75 times the brown sugar:

3/4*2.75
=3/4*2 \frac{3}{4}
Convert the mixed fraction into an improper fraction.
=3/4*11/4
=33/16
Convert back into a mixed fraction.
=2\frac{1}{16}

You would need 2 1/6 cups of brown sugar to make 11 dozen cookies.

Hope this helps.

A factory produces 42,000 computer monitors per day. The manager of the factory claims that fewer than 660 defective computer mo
Oksana_A [137]

Answer:

<h2> The manager's claim is likely to be true.</h2>

Step-by-step explanation:

We are given that the factory produces  42,000  computer monitors per day

And the claim is of this amount produces fewer than 660 are defective.

a random sample shows that of 240 monitors 2 are defective

to verify the factory managers claim we need to know how many 240s are there in 42000

=42000/240= 175

Since each 240 will give 2 defective monitors

175 will give= 175*2= 350

350 is less than 660 hence the managers claim is correct

What number is 53% of 470
Kazeer [188]

The word "of" is the same thing as a multiplication sign!


So instead see it this way:


53% × 470


To solve this, you can use the cross product method :


\frac{53}{100} = \frac{?}{470}


(470 × 63) ÷ 100 = ?


29 610 ÷ 100 = ?


296.1 = ?


53% of 470 is 296.1


There you go! I really hope this helped, if there's anything just let me know! :)

6. If a person adopts a pet, it's either a cat or a dog. 25% of the time, it's a cat and 75% of the time, it's a dog. If you mee
alina1380 [7]

Answer:

0.0156 probability that they got three cats.

0.4219 probability that they got three dogs.

Step-by-step explanation:

For each person there are only two possible outcomes. Either they adopted a dog, or a cat. The probability of a person adopting a cat or a dog is independent of any other person, which means that the binomial probability distribution is used to solve this question.

Binomial probability distribution

The binomial probability is the probability of exactly x successes on n repeated trials, and X can only have two outcomes.

P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}

In which C_{n,x} is the number of different combinations of x objects from a set of n elements, given by the following formula.

C_{n,x} = \frac{n!}{x!(n-x)!}

And p is the probability of X happening.

Three people:

This means that n = 3

What's the probability that they got three cats?

25% of the time it's a cat adopted, which means that p = 0.25

This is P(X = 3). So

P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}

P(X = 3) = C_{3,3}.(0.25)^{3}.(0.75)^{0} = 0.0156

0.0156 probability that they got three cats.

What's the probability that they got three dogs?

75% of the time it's a dog adopted, which means that p = 0.75

This is P(X = 3). So

P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}

P(X = 3) = C_{3,3}.(0.75)^{3}.(0.25)^{0} = 0.4219

0.4219 probability that they got three dogs.

How do you multiply the expression (3x+2)(4x-7)
Leona [35]

Answer:

You "FOIL" (First, Outer, Inner, Last).

12x^{2}  - 13x - 14

Step-by-step explanation:

You "FOIL" (First, Outer, Inner, Last). Basically, you have to multiple each term by each of the other terms.

(3x+2)(4x-7)

(3x)(4x) + (17)(3x) + (2)(4x) + (2)(-7)

12x^2 - 21x + 8x - 14

12x^2 - 13x - 14
