Answer:

The answer to your question is below

Step-by-step explanation:

f(x) = 27/x² - 16x

Evaluate the function when x:

x f(x)

-4 27/(-4)² - 16(-4) = 27/16 + 64 = 65.69

-3 27/(-3)² - 16(-3) = 27/9 + 48 = 51

- 2 27/(-2)² - 16(-2) = 27/4 + 32 = 38.75

- 1 27/(-1)² - 16(-1) = 27/1 + 64 = 91

1 27/(1)² - 16(1) = 27/1 - 16 = 11

2 27/(2)² - 16(2) = 27/4 - 32 = -25.25

3 27/(3)² - 16(3) = 27/9 - 48 = -45

Find the sixth term of the

Citrus2011 [14]

Answer:

$T_6 = 37.96875$

Step-by-step explanation:

Given

$a =5$

$r = \frac{3}{2}$

Required

Determine the 6th term

This is calculated as:

$T_n = ar^{n-1$

Where

$n = 6$

Substitute $n = 6$ , $a =5$ and $r = \frac{3}{2}$

$T_6 = 5 * (\frac{3}{2})^{6-1$

$T_6 = 5 * (\frac{3}{2})^{5$

$T_6 = 5 * (\frac{243}{32})$

$T_6 = 5 * \frac{243}{32}$

$T_6 = \frac{5 *243}{32}$

$T_6 = \frac{1215}{32}$

$T_6 = 37.96875$

You roll a six-sided number cube and flip a coin. What is the probability of rolling a number less than 2 and flipping heads? *

leonid [27]

Answer:

1/12

Step-by-step explanation:

First, you should already be able to understand that the only number less than 2 on this cube is 1. So, you can understand that there is a 1/6 chance because there is a total of 6 numbers, and out of those, only 1 of those are your answer.

Then, you will note that a coin only has 2 sides, so there is a 50/50 chance of getting heads, or 50%. Now, you will turn that into a fraction, which is 1/2.

Next, you will multiply to make the denominators the same. And what you do to the denominator must happen to the numerator. (1/6 * 2--> 1/12 and 1/2 * 6 = 1/12)

Hope this helps! :)

Answer:

Step-by-step explanation:

A is for sure wrong because we can see the distribution of the data showing us that the center is at 8. B is also wrong because the spread is only from 6.5 even though the table goes from 5. C would be correct because its symmetrical in shape.
