anna, becky, christina, debbie, and esther are the five candidates for student representative for the school board. two students
Flauer [41]

Probability that he will choose debbie and esther as the two representatives is 1/20 .

<h3>What is the meaning of Probability ?</h3>

Probability is the stream in mathematics in which likeliness of an event to happen is studied.

The range of probability lies between 0 to 1 , where 0 indicates uncertainty and 1 indicates certainty.

It is given that anna, becky, christina, debbie, and esther are the five candidates for student representative for the school board.

two students will be selected, and they will alternate attending the school board meetings.

all five students are equally well qualified, so the school superintendent decides to draw names at random.

probability he will choose debbie and esther as the two representatives = ?

Probability of chosing debbie is 1/5

Probability of choosing Esther is also 1/5

Either of them if chosen first the probability is 1/5

and the either of them chosen second the probability is 1/4

Probability that he will choose debbie and esther as the two representatives = (1/5)*(1/4) = 1/20 .

The endpoint coordinates of AB are A(2, -10) &amp; B(12, 5). Find the coordinates of the point that is 2/5 from A to B.

<h3>Answer: \large \boldsymbol {\sf 2\sqrt{13} \approx7,2}</h3>

Step-by-step explanation:

  • Find the distance between points A and B by the formula:

  • \large  \boldsymbol {\sf D=\sqrt{(x_1-x_2)^2+(y_1+y_2)^2} }

  • \large \boldsymbol{}  \sf D=\sqrt{(2-12)^2+(-10-5)^2} =\sqrt{100+225} =\boldsymbol {\sqrt{325}=5\sqrt{13}  }  

  • By the condition we are told to find 2/5 the distance between points A and B

  • \sf \large \boldsymbol {} \dfrac{2}{5} \cdot D=5\sqrt{13}  \cdot \dfrac{2}{5} =\boxed{\sf 2\sqrt{13}}

  • We can also find the distance between them through the  Pythagorean theorem we will complete a right triangle
  • AB²=AC²+BC²
  • AB=√AC²+BC²
  • Where AC=10  ; BC=15  
  • AB=\boldsymbol {\sf \sqrt{15^2+10^2}=\sqrt{325}=5\sqrt{13}   }
  • Then 2/5* AB=2\sqrt{13}

Karl and Mark are walking through the woods dropping breadcrumbs to help them find their way home. After ten minutes, their brea
musickatia [10]

In that three minute window (13 min - 10 min = 3 min), they used 24 bread crumbs (120 - 96 = 24).

So they're using 24 bread crumbs / 3 minutes or 8 crumbs/min.

The rate of change is a decrease of 8 crumbs/min from their basket.

Omar mows lawns for $9.25 an hour. He spends $7.50 on gas for the mower. How much does he make if he works h hours?
pochemuha
It depends how many hrs it take for him to mow a lawn. For example, if he worked 3 hours on a lawn he would get 27.75 or 9.25 times 3. Minus 7.50 = 20.50
