jek_recluse [69]

Answer:

57/55

Step-by-step explanation:

you have to find a common multiple, so it would be:

7/11=35/55

2/5=22/55

7/11 and 2/5 mean partial pages. she read part of a page. what she really read was 1 2/55 pages.

Suppose that the objective function coefficient for product C increases by $8. What impact will this have on the current values

maw [93]

When the objective function coefficient for the product increases by $8, the impact on the current values of the optimal solution is that the current solution will change.

<h3>What is an objective function?</h3>

An objective function simply means the function whose value is to be either maximized or minimized over the alternatives.

In this case, when the objective function coefficient for the product increases by $8, the impact on the current values of the optimal solution is that the current solution will change. The change is due to the varied objectives.

Find the probability of picking 2 blue marbles when 2 marbles are picked (with replacement) from a bag containing three blue and

Katen [24]

Answer: 0.5

Step-by-step explanation:

Given

There are 3 blue and 1 yellow marble

The chance of picking two marble out of 3 is $^3C_2$

The total no of ways of picking 2 marbles out of 4 is $^4C_2$

Therefore, the probability of picking 2 blue marbles

$\Rightarrow P=\dfrac{^3C_2}{^4C_2}\\\\\Rightarrow P=\dfrac{3\times 2}{4\times 3}\\\\\Rightarrow P=\dfrac{1}{2}$

. Mr. Marcum bought 7 tickets to a puppet show and spent $40. He bought a combination of child tickets for $4 each and adult tic

bonufazy [111]

Answer:

Mr. Marcum bought 5 child tickets and 2 adult tickets.

Step-by-step explanation:

First, assume that Mr. Marcum bought either 7 tickets of child tickets or 7 tickets of adult tickets. I'm using 7 child tickets for this working.

If Mr. Marcum bought 7 child tickets,

total money spent = $4 * 7 = $28

This is not equal to $40 and there has to be more money spent.

We should also calculate the price difference between the adult ticket and the child ticket.

Price difference per ticket = $10 - $4 = $6

This means that if Mr. Marcum bought an adult instead of a child ticket, he would spend $6 more.

In this case, Mr. Marcum has to spend $40- $28 = $12 more.

Hence, the number of adult tickets replacing the child tickets is $12/$6 = 2.

The number of child tickets = 7 - 2 = 5

The graph of an even function contains the point (3,-5). Which point must also be on the graph of the function?

Paul [167]

An even function is symmetrical about the y-axis. The mirror image of the point across the y-axis will also be on the graph. That point is found by changing the sign of the x-coordinate: (-3, -5).
