Three students are playing a game using the spinner above. Each student draws three boxes on a piece of paper. The spinner is sp

un, and each student writes the number in any one of the three boxes. The spinner is spun two more times, and each time the students write the number in a remaining empty box. The students then compare numbers, and whoever has the largest three-digit number wins the game.This game would be particularly useful in helping students' understanding of:

Answer:

Probability

Step-by-step explanation:

In this game, the players rely entirely on chance to win, rather than skill. Therefore, this game would be particularly useful in helping students' understanding of probability.

(Spoken from someone who played this exact game 2 years ago to learn about probability.)

Find the a26 arithmetic sequence: -15,-35,-55,-75<br> -515 <br> 460 <br> -490
Vlad [161]

Step-by-step explanation:

<h3><u>QU</u><u>ESTION</u><u>:</u><u>-</u></h3>

<u>Fin</u>d 26th term of the A.P --15,-35,-55,-75...

<h3><u>Solu</u><u>tion</u><u>:</u><u>-</u></h3>

First term=a=-15

Common Difference=d=-20

We know that

\boxed{\sf a_n=a+(n-1)d}

\\ \:\:\:\:\sf {:}\dashrightarrow a_{26}=-15+(26-1)(-20)

\\ \:\:\:\:\sf {:}\dashrightarrow a_{26}=-15+25(-20)

\\ \:\:\:\:\sf {:}\dashrightarrow a_{26}=-15+(-500)

\\ \:\:\:\:\sf {:}\dashrightarrow a_{26}=-15-500

\\ \:\:\:\:\sf {:}\dashrightarrow {\boxed{\bf a_{26}=-515}}

Santa has many toys to deliver on Elm Street. If there are 48 kids that live on Elm
kobusy [5.1K]

Answer: 3 : 1

Step-by-step explanation:

We know that there are 48 kids in Elm street.

12 of them are boys, then the number of girls will be:

48 - 12 = 36

So there are 12 boys and 36 girls.

Then the ratio of girls to boys is 36:12

We can divide both numbers by the same number and we will get an equivalent ratio, if we divide by 12 in both sides, we have:

36/12 : 12/12

3 : 1

Then the ratio is 3 to 1.

A ball has been thrown into the air its distance from the ground is given by the function s(t)=-16t^2+96t+100
slega [8]

Answer:

For t=3 sec the velocity change from positive to negative

Step-by-step explanation:

we have

s(t)=-16t^2+96t+100

This is the equation of a vertical parabola open downward (the leading coefficient is negative)

where

s(t) is the distance in feet

t is the time in seconds

We know that

To find out when the velocity change from positive to negative, we need to determine the turning point of the quadratic equation

The turning point of the quadratic equation is the vertex

so

Convert the quadratic equation into vertex form

s(t)=-16t^2+96t+100

Factor -16

s(t)=-16(t^2-6t)+100

Complete the square

s(t)=-16(t^2-6t+9)+100+144

s(t)=-16(t^2-6t+9)+244

Rewrite as perfect squares

s(t)=-16(t-3)^2+244

The vertex is the point (3,244)

therefore

For t=3 sec the velocity change from positive to negative

A company has an opportunity to bid on three contracts. Determine which would be the best investment given the information in th
MariettaO [177]

CONTRACT  PROFIT, (P)* OF PROFIT...(P)*. TO BREAK EVEN...LOSS, (P)* OF LOSS

Southeast $45,000,            50%                       30%                           $6,000, 20%

Southwest $60,000,            35%                      40%                          $10,000, 25%

California $112,000,           20%                       40%                          $40,000, 40%


I think that the best contract would be with SOUTHEAST. It probability of having a profit is higher than the other two at 50% while its probability of incurring a loss is lesser than the other two at 20%. 

Despite the bigger value of its contract profit of the other two, these value will still be greatly affected by its corresponding probabilities.
