The foci need to be equal distances from the center of the eclipse.

See the attached picture. I marked off all the points that were given as choice and from this you can see that that (-5,-4) and  (-5,2) are both 3 units away from the center.

The answer is: (-5,-4) and  (-5,2)

X-5/x<4

x²-5<4x
minus 4x both sides

(x-5)(x+1)<0
hmm
special points at x=-1 and x=5
when x=-2, we get 10<0 which is false
when x=0, we get -5<0 which is true
when x=6, we get 7<0 which is false
so the solution must be the range between -1 and 5

so if x<0

Dear Math Helper,
valentina_108 [34]

Answer:

n = 98, that is, she scored at the 98th percentile.

Step-by-step explanation:

When the distribution is normal, we use the z-score formula.

In a set with mean \mu and standard deviation \sigma, the zscore of a measure X is given by:

Z = \frac{X - \mu}{\sigma}

The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the pvalue, we get the probability that the value of the measure is greater than X.

In this question, we have that:

She scored 38, so X = 38

Test scores are normally distributed with a mean of 25 and a standard deviation of 6.4.

This means that \mu = 25, \sigma = 6.4

Find the percentile:

We have to find the pvalue of Z. So

Z = \frac{X - \mu}{\sigma}

Z = \frac{38 - 25}{6.4}

Z = 2.03

Z = 2.03 has a pvalue of 0.98(rounding to two decimal places).

So n = 98, that is, she scored at the 98th percentile.
