The answer would be i\sqrt{95}.

-81-14=-95; this gives us √(-95).

The complex number i is defined as the square root of negative 1.  This means we can take this out of the square root, and that gives us
i\sqrt{95}

Answer: A

Step-by-step explanation: once you line the numbers up in order from least the greatest, the two middle numbers will be 12. Add 12 + 12 and you get 24. Then divide it by 2 and get 12. That is your median. Your 1st quartile will be 10. Your second quartile will be 15. Your minimum number is 4 and your maximum number is 18.

Why is C the answer for this question?
Grace [21]

Step-by-step explanation:

A left Riemann sum approximates a definite integral as:

\int\limits^b_a {f(x)} \, dx \approx \sum\limits_{k=1}^{n}f(x_{k}) \Delta x \\where\ \Delta x = \frac{b-a}{n} \ and\ x_{k}=a+\Delta x \times (k-1)

Given ∫₂⁸ cos(x²) dx:

a = 2, b = 8, and f(x) = cos(x²)

Therefore, Δx = 6/n and x = 2 + (6/n) (k − 1).

Plugging into the sum:

∑₁ⁿ cos((2 + (6/n) (k − 1))²) (6/n)

Therefore, the answer is C.  Notice that answer D would be a right Riemann sum rather than a left (uses k instead of k−1).

Census Bureau data shows that the mean household income in the area served by a shopping mall is $64,500 per year with the stand
Elenna [48]

Considering the situation described, the null hypothesis is given as follows:

H_0: \mu = 64,000.

<h3>What are the hypothesis tested?</h3>

At the null hypothesis, it is tested if the <u>mean is the same as in the Census</u>, of $64,000, hence:

H_0: \mu = 64,000.

At the alternative hypothesis, it is tested if the mean is different from the Census, hence:

H_1: \mu \neq 64,000.
