6,282 in scientific notation would be _____?

Answers

Answer:

$6.282* 10^3$

Step-by-step explanation:

In the scientific notation we write a very large number or very small number as the product of a number between 0 to 9 and an exponent of 10,

Now, when we make a number between 0 to 9 by shifting decimal to left side then the power of 10 is positive number of shifting,

Here, the given number,

6,282

By the above explanation,

the scientific notation of 6,282 is $6.282* 10^3$

The scientific notation of 6,282 is 6.282 x 10³

The numbers 1 through 50 are written with red marker on slips of paper while the numbers 51 through 100 are written with blue marker on slips of paper. All the papers are put into a bag and shuffled. One card is
randomly selected.
a. Find the probability of selecting a number less than 16 or a number written in red.
b. Find the probability of selecting a number written in blue or a multiple of 5.

Answers

A. we want to pull 15 or less from the bag and there are 100 possibilities
$(15)/(100)$ = $(3)/(20)$
the probability is 3 out of 20

B. we are trying to pull a 55,60,65,75,80,85,90,95,or 100 that is 9 possibilities out of 100

$(9)/(100)$ is the possibility of pulling a multiple of 5 that is blue

a. The probability of picking a number less than 16 or a number in red is 65/100.
b. The probability of picking a number written in blue or a multiple of 5 is 70/100.

Find the real or imaginary solutions of the equation by factoring. x^4-8x^2=-16

Answers

ANSWER
$x=2$ or $x=-2$
EXPLANATION

The given equation is
${x}^(4) - 8 {x}^(2) = - 16.$

We set everything equal to zero to obtain,

${x}^(4) - 8 {x}^(2) + 16 = 0$

We rewrite the leading term to obtain,

${( {x}^(2) )}^(2) - 8( {x}^(2)) + 16 = 0$

This has now become a quadratic equation in
${x}^(2)$

We split the middle term to get,

${( {x}^(2) )}^(2) - 4 {x}^(2)- 4x^2+ 16 = 0$

We factor to get,

${x}^(2) (x^2-4)-4( {x}^(2)-4) = 0$

We factor further to get,

$( {x}^(2) -4)(x^2-4)= 0$

This gives

$( x-2)(x+2)(x-2)(x+2)= 0$

$( x-2)^2(x+2)^2= 0$

$x=2$ or $x=-2$
