An 8-pound bag of apples costs $17.50. What is the unit price?

Vesnalui [34]

8 pound bag full of apples = $17.50

The unit price is the amount we need to pay per bag.

Now, we need to set up a proportion.

8/17.50 = 1/x

Cross multiply.

8*x = 8x
17.50 * 1 = 17.50

8x = 17.5

Divide

8x/8 = 17.5/8
x= 17.5/8

x= 2.18

2.18 dollars per pound.

One gram of protein contains 4 calories. One gram of fat contains 9 calories. A snack has 60 calories from p grams of protein an

nikitadnepr [17]

Answer:

1.5 grams of protein.

Step-by-step explanation:

The equation that represents the relationship between protein and fat is as follows :

4p + 9f = 60 ....(1)

We need to find the grams of protein are there if there are 6 grams of fat in the snack.

Put f = 6 in the above equation (1).

4p + 9(6)= 60

4p + 54 = 60

Subtract 54 to the both sides,

4p + 54-54 = 60-54

4p = 6

⇒ p = 1.5 grams

It means the snack contains 1.5 grams of protein.

Answer:

i. A bar graph is an appropriate display.

ii. A bar graph is appropriate because the frequencies are given.

Step-by-step explanation:

A bar graph is a graphical method that can be used to present an information from a sample of data. It requires drawing of bars of equal width and distance with respect to the information given.

While a pie chart is a method that requires presenting information in a circular chart with respect to each data in sectors of different central angles.

For the given question, the most appropriate method to use is the bar graph with respect to the given information. Thus, the statements that are correct about the data in the table are:

i. A bar graph is an appropriate display.

ii. A bar graph is appropriate because the frequencies are given.

Alice and Bob take turns in rolling a fair dice. Whoever gets "6" first wins the game. Alice starts the game. What are the chanc

WINSTONCH [101]

Answer:

Probability of Alice win the game is $\frac{6}{11}$

Step-by-step explanation:

When a die is rolled then probability of getting 6 is $=\frac{1}{6}$

So probability of winning the game $P(W)=\frac{1}{6}$

Now probability of losing the game $P(L)=1-\frac{1}{6}=\frac{5}{6}$

It is given that Alice starts the game

So either Alice win the game in 1st attempt or 3rd or 5th .....

So probability that Alice win the game $=P(W)+P(L)P(L)P(W)+P(L)P(L)P(L)P(L)P(W)+.....$

So $P(w)=\frac{1}{6}+\frac{5}{6}\times \frac{5}{6}\times \frac{1}{6}+\frac{5}{6}\times \frac{5}{6}\times\frac{5}{6} \times \frac{5}{6}\times \frac{1}{6}......$

Now taking $\frac{1}{6}$ common and applying sum of infinite GP $P(W)=\frac{1}{6}\times \frac{1}{1-\frac{25}{36}}=\frac{1}{6}\times \frac{36}{11}=\frac{6}{11}$

Probability of Alice win the game is $\frac{6}{11}$
