<u>The probability is </u><u>1/12</u>

The probability of choosing a nickel is 9/18 = 1/2. The probability of choosing a dime is 3/18 (because there are 3 dimes and since there is replacement, we still have 18 total coins to choose). With these, we get: (1/2) * (3/18) = 3/36 = 1/12

Tammy baked a batch of 20 cupcakes. Daniella baked
ElenaW [278]

Multiplication is the process of multiplying. The total number of cupcakes that are produced by the 3 girls is 44.

<h3>What is multiplication?</h3>

Multiplication is the process of multiplying, therefore, adding a number to itself for the number of times stated. For example, 3 × 4 means 3 is added to itself 4 times, and vice versa for the other number.

Given that Tammy baked a batch of 20 cupcakes and Daniella baked 4/5 as many cupcakes as Tammy. Therefore, the number of cupcakes made by Daniella is,

Number of cupcakes made by Daniella

= (4/5)×(Number of cupcakes made by Tammy)

= (4/5) × 20

= 16

Now, if Miko baked 1/2 as many cupcakes as Daniella. Therefore, the number of cupcakes made by Miko is,

Number of cupcakes made by Miko

= (1/2) × (Number of cupcakes made by Daniella)

= (1/2) × 16

= 8

Further, the total number of cupcakes that are produced are,

Number of cupcakes = 20 + 16 + 8 = 44

Hence, the total number of cupcakes that are produced by the 3 girls is 44.

Write a compound inequality that represents the annual profits P ( in millions or dollars) from 2006 to 2013.
alisha [4.7K]

Answer:

(50000000 ≤ P ≤ 90000000)

Step-by-step explanation:

The chart represents annual profits in millions of dollars. From the chart, the least annual profit is 50 million dollars and that was is the year 2009.

The highest annual profit is 90 million dollars and that was is the year 2012.

The compound inequality representing the annual profits P(in millions or dollars) from 2006 to 2013 would be

(50000000 ≤ P ≤ 90000000)
