What is 1 divided by 5^-2? Please give clear explanation. thanks.
Pani-rosa [81]
1 / 5^-2

First, let's work out the denominator.
5^ -2 = 1/25. When an exponent is negative, it means to put a 1 over the product. Like we did earlier.

Now we have 1 / (1/25). 

1 / (1/25)
Divide 1 by 25.
1 / 0.04
Divide 1 by 0.04
25

The answer is 25!

Now if you make this answer as the Brainliest I will appreciate it very much. And for a limited time answer, and no scam or joke,  you will receive your very own flying space ship! No scam at all! Try it. Just press the mark as Brainliest and watch your spaceship land in your backyard! But seriously I will appreciate it if you mark this answer as the Brainliest.

ALGEBRA QUESTION WILL GIVE BRAINLIEST IF CORRECT!!!
Ulleksa [173]

Answer:

Step-by-step explanation:

(f + g)(x) simply means that you are adding together the 2 functions that are written in terms of x.

x^3-x+x^3+2x^2-10

The only like terms we have there are the x-cubed's, so

2x^3+2x^2-x-10=(f+g)(x)

In a random sample, 10 students were asked to compute the distance they travel one way to school to the nearest tenth of a mile.
elixir [45]

Answer:

Mean = 3.12, Variance = 3.324, Standard deviation = 1.8232

Step-by-step explanation:

Total number of students = 10 students.

Given data, 1.1, 5.2, 3.6, 5.0, 4.8, 1.8, 2.2, 5.2, 1.5, 0.8

To find the mean, at first we have to take the sum of all given data and then divide with the number of students.

Let the data is X, = 1.1, + 5.2, + 3.6, + 5.0, + 4.8, + 1.8, + 2.2, + 5.2, + 1.5, + 0.8 = 31.2

Mean = 31.2 / 10 = 3.12

\text{Standard deviation, S} = \sqrt{\frac{\sum x^{2} - \left [ (\sum x)^{2}/n \right ]}{n-1}} \\S = 1.8232 \\\rm The \ Variance = S^{2} = 3.324
