Answer:

Sara drives 22.5 miles per gallon and 299.25 miles in 13.3 gallons of gas.

Step-by-step explanation:

Sara drives 72 miles on 3.2 gallons of gas and we have to calculate how many miles per gallon she can drive.

By unitary method

∵ 3.2 gallons of gas is used to drive = 72 miles

∴ 1  gallon of gas is used to drive = 72÷3.2 miles

                                                       = 22.5 miles

∴ 13.3 gallons of gas is used to drive = 13.3×22.5 = 299.25 miles

Therefore Sara drives 22.5 miles per gallon of gas and on 13.3 gallons of gas she drives 299.25 miles.

In the figure below, ZAPE and ZEPD are congruent.
Taya2010 [7]

Answer:

54degrees

Step-by-step explanation:

From the given diagram;

2<P + 136 + 74 + 42  = 360 (sum of angle at a point is 360degrees)

2<P +252 = 360

2<P = 360 - 252

2<P = 108

<P = 108/2

<P = 54

Hence the measure of <P is 54degrees

A company that manufactures guitars has a fixed cost of $100,000. It costs $100 to produce each guitar and the selling price is
miv72 [106K]

a. Write the cost function:: C(x) = 100x + 100,000 where x is number of guitars

---------------------------------

b. Write the revenue function:: R(x) = 300x where x is number of guitars

-----------------------

c. Find the profit function.

Profit = Revenue - Cost

P(x) = R(x) - C(x)

P(x) = [ R(x) ] - [ C(x) ]

P(x) = [ 300x ] - [ 100x+100,000 ]

P(x) = 300x - 100x-100,000

P(x) = 200x - 100,000

The break even point is when the profit is 0 dollars. You don't lose any money. And you don't gain any money.

Solve 125x - 100,000 = 0

125x = 100,000

x = 800 (# of guitars made and sold)

likoan [24]

The completion of the tabs are:

  • The value of \bar p is the sample proportion.
  • The value of  \bar q is found by evaluating 1-\=p
  • The value of n is the sample size.
  • The value of E is the margin of error.
  • The value of p is the population proportion.
  • α = 0.05.

<h3>What is the margin of error.?</h3>

You may calculate how many percentage points your findings will deviate from the actual population figure by using something called a margin of error.

In conclusion

  • The worth of p^ is the fraction of the sample.
  • The worth of p^ is discovered by assessing
  • The sample size is given by the number n.
  • The margin of error is expressed as E's value.
  • The population percentage is represented by the value of p.
  • α = 0.05.

In conclusion,
