In a contest to guess the number of jelly beans in a jar, Alice guessed 25;Betty, 18;Clare,23;Dotty,19;Edith,24;and Fran,17. Two

vampirchik [111]

Answer:

<em>There are 21 jelly beans in the jar.</em>

Step-by-step explanation:

Suppose, the number of jelly beans in the jar is $x$

Two were off by 2, two were off by 3, two were off by 4. That means, the six guessed number will be: $(x+2), (x-2), (x+3), (x-3), (x+4), (x-4)$

Given that, Alice guessed 25; Betty, 18; Clare, 23; Dotty, 19; Edith, 24; and Fran, 17.

So, the sum of all six guessed number will be: $25+18+23+19+24+17=126$

Thus, the equation will be..........

$(x+2)+(x-2)+(x+3)+(x-3)+(x+4)+(x-4)= 126\\ \\ 6x= 126\\ \\ x=\frac{126}{6}=21$

So, the number of jelly beans in the jar is 21.

For the simple harmonic motion equation d=2 sin (pi/3 t), what is the maximum displacement from the equilibrium position?. . . .

Pie

<span>Yes, it is.

Here's something to think about:
The function sin(x) is never bigger than 1, no matter what number you choose to plug into it. therefore the maximum value of the equation d= 2sin(x) is 2.

I hope my answer has come to your help. Thank you for posting your question here in Brainly.
