Solution

(a) You are equally likely to get any of the six numbers.

(b) You would expect to get a six in about 1

6

of the throws, so 100 sixes.

(c) Yes, in fact you would expect to get about 100 of each number.

Use one of the following to describe each one of the statements (a) to (d).

Certain

Very likely

(a) It will snow tomorrow.

Dwayne earned $530 working 2 jobs. One job pays $14 per hour and the other pays $10 per hour. He worked a total of 45 hours how
Naddik [55]

Answer:

Dwayne worked 20 hours for first job and 25 hours for second job.

Step-by-step explanation:

Let the number of hours worked by Dwayne in first job = x

Let the number of hours worked by Dwayne in second job = y

Then, \[x + y = 45\] ----------------- (1)

First job pays $14 per hour

Second job pays $10 per hour

=> \[14x + 10y = 530\] ------------- (2)

Solving (1) and (2):

\[y = 45 - x\]

Substituting in (2):

\[14x + 10 (45-x) = 530\]

=> \[14x + 450- 10x = 530\]

=> \[4x  = 530 - 450\]

=> \[4x  = 80\]

=> \[x  = 20\]

Substituting in (1):

\[y = 45 - x\]

=> \[y = 45 - 20\]

=> \[y = 25 \]
