Simplify the expression with using scientific notation (4 times 10 8)2
kifflom [539]

The scientific notation:

a\cdot10^n\\\\1\leq a < 10;\ n\in\mathbb{Z}

(4\cdot10^8)^2=4^2(10^8)^2=16\cdot10^{8\cdot2}=16\cdot10^{16}\\\\=1.6\cdot10\cdot10^{16}=1.6\cdot10^{17}

Used:

(a\cdot b)^n=a^n\cdot b^n\\\\(a^n)^m=a^{n\cdot m}\\\\a^n\cdot a=a^{n+1}

Answer: (4 × 10⁸)² = 1.6 × 10¹⁷

You multiply two integers. You increase one of them by 1 and decrease the other
snow_tiger [21]

Integers are numbers without decimals

The integers could you have multiplied are 9 and 2

Let the numbers be x and y

So, we have:

\mathbf{x \times y}

Increase x by 1 and reduce y by 1.

So, we have

\mathbf{(x +1) \times (y -1) = 6 + xy }

Open brackets

\mathbf{xy -x + y - 1 = 6 + xy}

Subtract xy from both sides

\mathbf{ -x + y - 1 = 6}

Collect like terms

\mathbf{ -x + y = 6 + 1}

\mathbf{ -x + y = 7}

Rewrite as:

\mathbf{ y -x= 7}

The above means that, the difference between the integers is 7.

There are several integers that fit the above <em>description</em>;

One possibility is: 9 and 2

PLEASE HELP ME WITH THIS!!!!!​
nadezda [96]

For the given experiment of spinning a spinner and drawing a card, we will see that:

  • A) Yes, the events are independent.
  • B) P(3 and A) = 1/16
  • C) P(5 and C) = 0
  • D) P(4) = 1/4
  •     P(B or C) = 1/2
  • E) P(3 and not D) = 3/16

<h3>What are independent events?</h3>

We say that two events are independent if the outcome of one does not affect the outcome of the other.

In this case, the outcome of the spinner clearly does not affect the outcome of the card draw, so the events are independent.

<h3>How to get the probabilities?</h3>

B) First we want to get the probability of getting 3 and A.

The probability of getting a 3 when drawing a card is given by the quotient between the numbers of card with the number 3 (only one) and the total number of cards, so we have:

p = 1/4

Similar for the case of the spinner, the letter A appears twice, and there are a total of 8 letters, then the probability is:

q = 2/8 = 1/4

The joint probability is the product of the two individual probabilities, we have:

P(3 and A) = p*q = 1/4*1/4 = 1/16

C) The probability of getting a 5 and the letter C is 0, because there is no card with the number 5.

D) P(4) is the probability of drawing the card with the number 4, this is:

p = 1/4

P(B or C) is the probability of spinning the letter B or C. There are 2 B's and 2 C's, and a total of 8 letters, so the probability is:

q = (2 + 2)/8 = 1/2

E) P(1 and not D) is equal to: P(1 and A or B or C).

P(1) is 1/4.

P(A or B or C) is 6 over 8 (because there are 6 cards that are either an A, a B, or a C)

Then the joint probability is:

P(1 and not D) = (1/4)*(6/8) = 3/16
