Ida needs to hire a singer for her wedding. Singer A is offering his services for an initial $65 in addition to $13.15 per hour.
Naddik [55]

Answer:

4.4 hours

Step-by-step explanation:

Let the number of hours = x

Ida needs to hire a singer for her wedding.

For Singer A

Singer A is offering his services for an initial $65 in addition to $13.15 per hour.

65 + 13.15x

Singer B

Singer B is offering her services for an initial $73 in addition to $11.35 per hour.

73 + 11.35x

We equate both singers together

Singer A = Singer B

65 + 13.15x = 73 + 11.35x

We collect like terms

13.15x - 11.35x = 73 - 65

1.8x = 8

x = 8/1.8

x = 4.4444444444 hours

Approximately = 4.4 hours

The two singers will charge the same amount of money after 4.4 hours

In a class of 125 students, 28 are computer science majors, 52 are mechanical engineering majors, 12 are civil engineers and the
Studentka2010 [4]

Answer:

The probability none mechanical engineering majors is 0.03967.

Step-by-step explanation:

Given that,

Total students = 125

Number of students in computer science = 28

Number of students in mechanical engineering = 52

Number of students in civil engineering= 12

Suppose six students from the class are chosen at random what is the probability none are mechanical engineering majors?

We need to calculate the probability none are mechanical engineering majors

Using given data

None mechanical engineering majors = \dfrac{125-52}{125}=0.584

If six students from the class are chosen at random then

The probability none are mechanical engineering majors will be

P_{nme}=(0.584)^6

P_{nme}=0.03967

Hence, The probability none mechanical engineering majors is 0.03967.
