What is (-6)^8/(-6)^2

Mathematics

inn [45]3 years ago

So, you're looking for:
\frac{(-6)^{8} }{(-6)^{2}}
With exponents when you're dividing, you can subtract the exponents when the bases are the same. It works for this.
8-2= 6, So now it's (-6)^6
It's an even exponent, so the answer will be a positive number.
(-6)^6=  46,656
You can even make sure that you're correct by not changing the expression.
So, the answer is 46,656.

Juliette [100K]

Answer: 0.4667

Step-by-step explanation:

According to 68–95–99.7 rule , About  99.7% of all data values lies with in 3 standard deviations from population mean (\mu).

Here , margin of error = 3s , where s is standard deviation.

As per given , we have want our sample mean \overline{x} to estimate μ μ with an error of no more than 1.4 point in either direction.

If 99.7% of all samples give an \overline{x} within 1.4 , it means that

3s=1.4

Divide boths ides by 3 , we get

s=0.466666666667\approx0.4667

Hence, So \overline{x} must have 0.4667 as standard deviation so that 99.7 % 99.7% of all samples give an \overline{x} within 1.4 point of μ .

Alarger number is 2 more than 4 times a smaller number. The larger number is also 8 more than 2 times the smaller number. 4x+2 y
Umnica [9.8K]

Answer:

the value of the smallest number is 3

Step-by-step explanation:

The computation of the value of the smaller number is shown below:

Given that

y = 4x + 2

y = 2x + 8

Now equate these two equations

4x + 2 = 2x + 8

4x - 2x = 8 - 2

2x = 6

x = 3

Hence, the value of the smallest number is 3

The same is to be considered

There are two colored marbles and one white marble in a box. Julie mixes the marbles and then Sam draws two marbles at random wi
tino4ka555 [31]
At first there are three marbles for Sam to pick from. the possibility of drawing a colored marble is 2/3. if Sam picks one of the colored marbles, the possibility of therefore (if he'd drawn the colored marble) drawing the second colored marble is 1/2. for the possibility of those happening consequently, we have to multiply the possibilities. 2/3 * 1/2 is 2/6 is 1/3. which means Sam wins in 33.333...% cases. Julie has a better chance of winning.

adding a white marble would change the possibilities to 1/2 and 1/3 consequently, meaning Sam wins in 1/2 * 1/3 = 1/6 = 16.7% cases, which is even less fair.

adding a colored marble would change the possibilities to 3/4 and 2/3 consequently, meaning Sam wins in 3/4 * 2/3 = 6/12 = 50% cases, which finally makes the game fair.
