Step-by-step explanation:

2. 20-12=8, 8divided by 4=2

3. 363 divided by 3=121(this is the avg of the consecutive multiples so one multiple must be 11 above and another 11 below

4.66 divided by 3=22, 22x 2 and 22 x 5

5.2 x2=4, 13-4=9, 9 divided by 2 is 4.5

tensa zangetsu [6.8K]

<u>Explanation </u><u>:</u>

<u>Given that:</u>

  • In a box 25 cards are there and 1 to 25 numbers are written on them.

  • • One card is drawn randomly.

<u>To Find:</u>

  • • What is the probability that it is multiple of 5.

<u>We know that:</u>

P(E)= F/T

<u>Where,</u>

P(E)= Probability of an event

• F= Favourable outcomes . T = Total outcomes

<u>We have:</u>

F = Number of cards which are multiple of 5

Cards having the number 5, 10, 15, 20, 25 are the multiples of 5.

So, F = 5

T = Total number of cards

• T = 25

P(F) The probabilityP(E) = The probability that it is multiple of 5

Finding the probability that it is multiple of 5:

  • P(E)= 5/25

  • P(E)=1/5

<u>Hence,</u>

The probability that it is multiple of 5 is ⅕

Step 1 is to find how far apart W and Y are:
-7 - (-31) = 24

Now find 1/8 of that distance: 1/8 • 24 = 3

Now move 3 units from -31 towards -7: -31 + 3 = -28

Scientists found that a certain particle of dust doubles every 30 minutes. If the scientists tests this out with 21 grams of the
monitta

Answer: 1.663\times 10^{30}\ gm

Step-by-step explanation:

Given

Population of dust particle doubles every 30 minutes

If the initial sample is 21 grams

The model to predict the population will be

\Rightarrow P=21\cdot 2^{2t}

Where t=time in hours

A day has 24 hours . So, for 2 days time is 48 hours

Population is given by

\Rightarrow P=21\cdot 2^{2\times 48}\\\\\Rightarrow P=21\times 2^{96}\\\\\Rightarrow P=1.663\times 10^{30}\ gm
