Answer:
log2(0.25) = -2
512 = 8^3
Step-by-step explanation:
- <em>Use of formula: </em><em>loga (b) = c ⇔ b = a^c</em>
Rewrite the following equation in logarithmic form.
0.25 = 2^-2
Rewrite the following equation in exponential form. log8 (512) = 3
Answer:
60 × 66,666
60 × 666,666
Step-by-step explanation:
If you look at the pattern on the top numbers, you can see that there is one six that keeps on getting added. I'm not sure of my answer, but that is what I would put.
Yes because if you look at the tenths place you will see that 8 is bigger than 7
The variance of a distribution is the square of the standard deviation
The variance of the data is 2.2
<h3>How to calculate the variance</h3>
Start by calculating the expected value using:

So, we have:

This gives

Next, calculate E(x^2) using:

So, we have:


The variance is then calculated as:

So, we have:


Approximate

Hence, the variance of the data is 2.2

Therefore, f(x) = 2x + 3 is your derivative function, and you need to find the original curve. So find the antiderivative using the given conditions...
∫f(x) = ∫2x + 3 dx
F(x) = x^2 + 3x + C
2 = (1)^2 + 3(1) + C
2 = 4 + C
C= -2
Therefore, the curve is F(x) = x^2 + 3x - 2
Proof: The derivative is the slope at every (x, y) point. The derivative of F(x) comes out to be 2x + 3, so we have found the curve. Plug in x = 1, and y = 2, so the conditions have been met.
