Answers

Answer 1

Answer: =>32 - 6x + 7x = -15 + 28
=>32 - 6x + 7x + 15 -28 =0
=>32 -28 + 15 -6x + 7x =0
=>19 + x =0
=>x = -19

Hope it helps !!!

A set of data with a mean of 45 and a standard deviation of 8.3 is normally distributed. Find the value that is –2 standard deviations away from the mean.

Answers

45+8.3 = 53.3

45 - (2(8.3)) = 28.4

The value is 28.4 that is –2 standard deviations away from the mean.

Answer: 28.4

Step-by-step explanation:

Given : A set of data with a mean of $\mu= 45$ and a standard deviation of $\sigma=8.3$ is normally distributed.

Now, the value that is –2 standard deviations away from the mean is given by :-

$x=\mu-2\sigma\n\n\Rightrrrow\ x=45-2(8.3)\n\n\Rightarrow\ x=45-16.6\n\n\Rightrrrow\ x=28.4$

Hence, the value that is –2 standard deviations away from the mean. = 28.4

Write the equation for a parabola with the focus at(-1, 4) and the equation of the directrix x = 5.
(x + 1)2 = 3(y-4)
(y-4)2 = 12(x + 1)
(y-2)2 = -3(x – 4)
(y-4)2 = –12(x - 2)

Answers

The answer is (y - 4)2 = -12(x - 2)
Since the graph is facing the left, the starting equation would be (y - k)2 = -4p(x - h).
(h, k) is the vertex of the graph. If you plot the focus and the directrix, you can see that the distance is 6. Divide 6 by 2, thus the vertex should be 3 squares away from the focus and 3 squares away from the directrix. The vertex is (2, 4). And since the distance from the focus to the vertex and the distance from the directrix to the vertex is 3, P = 3.
Insert the numbers in and you should get the last choice.
