Mathematics

Lubov Fominskaja [6]3 years ago
6 0

Answer:

  68.44%

Step-by-step explanation:

You compute the average the way you compute any average: add up the numbers and divide by their number.

Multiplication is a useful way to shorten the effort of repeated addition.

  (64% × 3 + 58% × 7 + 88% × 3 +33% + 100% × 2)/(3 +7 +3 + 1 + 2)

  = 1095%/16 = 68.4375%

  ≈ 68.44% . . . the average mark for the class

Paladinen [302]

Answer:

<h2>C= 400P+ 600</h2>

Step-by-step explanation:

In this problem, we are to model the equation for the total cost of producing a phone

Given that the fixed cost is $600

Also, the total cost of producing 4 phones in a day is $1600

hence the cost of producing 1 phone would be 1600/4= $400

the equation for producing p phones would be

C= 400P+ 600

This equation is the same as the equation of a straight line Y=mx+c

with C=y

400= m= gradient

P=x, the dependent variable

600= c the constant term.

AveGali [126]

Answer:

The power developed by the 1st crane is twice the power developed by the 2nd crane.

Step-by-step explanation:

According to the question,

work done by both of the cranes are the same. Let it be W.

Then power developed by the first crane,

= P_{1} = \frac {W}{20} unit -----------------(1)

and, the power developed by the 2nd crane,

= P_{2} = \frac {W}{40} unit ------------------(2)

So, we get that,

P_{2} = \frac {P_{1}}{2}

So, the power developed by the 1st crane is twice the power developed by the 2nd crane.
