Write an equation for the simple harmonic motion of a ball on a spring that starts at its lowest point of 6 inches below equilib

rium, bounces to it maximum height of 6 inches above equilibrium and returns to its lowest point in a total of 2 seconds. (think about amplitude and period)

So a general harmonic equation is Asin(2πt/T). Little t is just a variable. 6 inches is the height of one maximum and one minimum from equilibrium, so that is the amplitude A. T is the period, or the time of one cycle (or wavelength), which is 2 seconds.

The equation is therefore (in terms of seconds and inches), 6*sin(2πt/2), or 6*sin(πt).

The list shows the number of stories in the 11 tallest buildings
tangare [24]

The median and mode of the given data is 30 and 32 respectively.

Step-by-step explanation:

Given,

The number of stories in 11 buildings are 17,19,20,21,24,30,33,37,38,40,40

To find the median and mode of the data.

Formula

Mean = sum of the data ÷ number of terms

If the number of term is odd, the median = \frac{n+1}{2} th term

Mode = 3 Median - 2 mean

Now,

Mean = (17+19+20+21+24+30+33+37+38+40+40)÷11 = 29

Median = \frac{11+1}{2} th term = 6th term = 30

Hence,

Mode = 3×30-2×29

= 90-58 = 32

Two dice are thrown at the same time. Find the probability of getting
astra-53 [7]

<u>Answer</u><u>:</u>

(i) = ⅙

(ii) = 1/12

<u>Step-by-step-explaination</u><u>:</u>

Each dice have 6 number

Then for 2 dice the total number is 12

Now,

(i) the same number on both dice.

Probability (P) = no. of outcome ÷ no. of total outcomes

P = 2 ÷ 12 = ⅙

(ii) different numbers on both dice.

Probability (P) = no. of outcome ÷ no. of total outcomes

P = 1 ÷ 12 = 1/12
