Answer:

Only 71 is an outlier.

Step-by-step explanation:

The give data is

71, 84, 133, 140, 158, 166, 170, 171, 188, 198

Divide the data in two equal parts.

(71, 84, 133, 140, 158), (166, 170, 171, 188, 198)

Now, divide each parenthesis in two equal parts.

(71, 84), 133, (140, 158), (166, 170), 171, (188, 198)

It means first quartile is 133 and third quartile is 171.

The interquartile range is

$IQR=Q_3-Q_1=171-133=38$

If the data lies outside the range $[Q_1-1.5(IQR),Q_3+1.5(IQR)]$ , then the data set has outliers.

$[Q_1-1.5(IQR),Q_3+1.5(IQR)]=[133-1.5(38),171+1.5(38)]$

$[Q_1-1.5(IQR),Q_3+1.5(IQR)]=[76,228]$

It means if the data lies outside the interval [76,228], then it is an outlier.

Since 71∉[76,228], therefore only 71 is an outlier.

Consider a total of 1,000 people. If it was said that within 1 deviation (of the mean) of all people like MATH 123, how many of

Lesechka [4]

Answer:

680 students

Step-by-step explanation:

The 68 - 95 - 99.7 rule (empirical rule) states that 68% of the population lies within one standard deviation of the mean, 95% of the population lies within two standard deviations and 95% of the population lies within three standard deviations.

Hence since it was said that within 1 deviation (of the mean) of all people like MATH 123, therefore the number of people that like MATH 123 is:

number of people that like MATH 123 = 68% of the population

number of people that like MATH 123 = 0.68 * 1000

number of people that like MATH 123 = 680 students

SpyIntel [72]

Answer:

$\frac{8}{9}{x}^{2}$

Step-by-step explanation:

All you do is multiply straight across [both denominator and numerator] to arrive at your answer. Then, multiplying two x's together gives you ${x}^{2}$ . So, with all that being said, you have your answer.

Helen [10]

Answer:

y= 1/12(x-0)^2+0

this answer works as an upward parabola

Step-by-step explanation:

The formula for a veritcal parabola is y=1/4p(x-h)^2+k
(h,k)= coordinates of the vertex of the parabola
p= absolute value of the distance from the vertex to the focus/directrix
In this problem, it is given that the vertex is at the origin (0,0) and the focus (the bulb), is 3 centimeters away from the vertex.
Now, you know the values of the variables. Fill in the values
FROM THE FORMULA: 1/4p turns into 1/12 since p is 3.
(x-h)^2+k turns into (x-0)^2+0, since h and k where the values of the vertex which was 0,0
once all the variables are given values (except x and y) you have made your equation!
The answer is y=1/12(x-0)^2+0

MARK BRAINLIEST! this took forever, and I know this is the right answer since I got a perfect grade when I turned mine in.
