Hector works 10 hours per week at a part-time job. His original pay rate was $8.50 per hour, but he recently received a raise of

Fofino [41]

Answer:

$1.50

Step-by-step explanation:

Given the total weekly pay of Hector modeled by the equation;

y = 10(8.5 + x)

We are to find the amount of Hector's raise per hour x given the total oay y = $100

Substitute y = 100 into the equation and find x as shown;

y = 10(8.5 + x)

100 = 10(8.5+x)

100/10 = 8.5 + x

10 = 8.5 + x

x = 10 - 8.5

x = 1.5

Hence the amount of Hector's raise per hour is $1.50

If you randomly pick a number from 1 to 25, what is the probability that the number will have “2” as one of the digits?

Paul [167]

Answer:

$\frac{7}{25}$

Step-by-step explanation:

In the interval $n\in [1, 25]$ , there are $(25-1)+1=25$ numbers total. The number $2$ appears as the ones digit for $3$ numbers in this interval: $0\bold{2}, 1\bold{2}, 2\bold{2}$ . The subset $n\in [20, 25]$ marks the interval of numbers in the set that has the number $2$ as the tens digit. There are $(5-1)+1=5$ numbers in this set. Since $22$ is counted twice, there are a total of $5+3-1=7$ numbers in the original interval that contain the number $2$ . Therefore, the probability a random selected number from the interval has the number $2$ in it is $\fbox{$\frac{7}{25}$}$ .
