A bakery uses ounces of icing for every of a cake. What is the unit rate in ounces of icing per cake?

mr_godi [17]

Answer:

The unit rate in ounces of icing per cake is 40 4/5 or 204/5

Complete statement and question:

A bakery uses 10 1/5 ounces of icing for every 1/4 of a cake. What is the unit rate in ounces of icing per cake

Source: A previous question found at brainly

Step-by-step explanation:

1. Let's review the information given to us to answer the question correctly:

Size of icing for every 1/4 of a cake = 10 1/5 ounces or 51/5 ounces

2. What is the unit rate in ounces of icing per cake?

For answering the question, we will use the Rule of Three Simple, this way:

Unit rate in ounces of icing per cake * 1/4 of a cake = Total cake * Unit rate in ounces of icing per 1/4 of a cake

Replacing with the real values, we have:

Unit rate in ounces of icing per cake * 1/4 = 1 * 51/5

Unit rate in ounces of icing per cake = 51/5 / 1/4

Unit rate in ounces of icing per cake = 51/5 * 4/1

Unit rate in ounces of icing per cake = 204/5 ounces or 40 4/5 ounces

The unit rate in ounces of icing per cake is 40 4/5 or 204/5

Suppose that 70% of the orders on a particular website are shipped to the person who is making the order and the remaining 30% a

Lera25 [3.4K]

Answer:

0.18 ; 0.1875 ; No

Step-by-step explanation:

Let:

Person making the order = P

Other person = O

Gift wrapping = w

P(p) = 0.7 ; P(O) = 0.3 ; p(w|O) = 0.60 ; P(w|P) = 0.10

What is the probability that a randomly selected order will be a gift wrapped and sent to a person other than the person making the order?

Using the relation :

P(W|O) = P(WnO) / P(O)

P(WnO) = P(W|O) * P(O)

P(WnO) = 0.60 * 0.3 = 0.18

b. What is the probability that a randomly selected order will be gift wrapped?

P(W) = P(W|O) * P(O) + P(W|P) * P(P)

P(W) = (0.60 * 0.3) + (0.1 * 0.7)

P(W) = 0.18 + 0.07

P(W) = 0.1875

c. Is gift wrapping independent of the destination of the gifts? Justify your response statistically

No.

For independent events the occurrence of A does not impact the occurrence if the other.
