Find the exponential regression equation that best fits the data

RoseWind [281]

Since the opposite side of the needed value is 90°, the side that contains x is also 90°. So you would have to subtract 29 from 90 to get x

Answer:

The correct answer is actually B. x - 3y < 5

Step-by-step explanation:

Because you must convert the equation to y-intercept form first.

Which makes it y = 1/3x - 1.6

So y = 1.6 and using the slope of 1/3x you can find that x = 5

Need more points ??? solve this .....only first part for 50 points .....and follow me also!

leonid [27]

Answer:

see below

Step-by-step explanation:

i.

= √(3 + 4i)

= 2 + i

ii.

= √(-8 + 6i)

= √2(-4 + 3i)

iii.

= √(-40 - 42i)

= √-2(20 + 21i)

iv.

= √i

v.

= $\sqrt{\frac{2 + 3i}{5 - 4i} } +\sqrt{\frac{2-3i}{5+4i} }$

= $\sqrt{\frac{-2+23i}{41} } +\sqrt{\frac{2-3i}{46} }$

Reports on a student's ACT, SAT, or MCAT usually give the percentile as well as the actual score. The percentile is just the cum

Nimfa-mama [501]

Answer:

The percentile for William is 76.97.

Step-by-step explanation:

1) Previous concepts

Normal distribution, is a "probability distribution that is symmetric about the mean, showing that data near the mean are more frequent in occurrence than data far from the mean".

The Z-score is "a numerical measurement used in statistics of a value's relationship to the mean (average) of a group of values, measured in terms of standard deviations from the mean".

Let X the random variable that represent the scors of a population, and for this case we know the distribution for X is given by:

$X \sim N(25.2,6.5)$

Where $\mu=25.2$ and $\sigma=6.5$

2) Solution to the problem

We are interested in find the percentile for the score of 30 obtained by William. The best way to solve this problem is using the z score formula given by:

$z=\frac{X-\mu}{\sigma}$
