Answer:

Option: a is correct.

a .mean or median because there is no outlier

Step-by-step explanation:

Mean and median both try to measure the "central tendency" in a data set.

Clearly from the set of the values or data points:

{29 , 29, 29 , 28, 28, 27}

We could see that the data values are close too each other i.e. there is not outlier ( An outlier is a point that stand out of the rest points i.e. that value is either too high or low as compared to the other data points).

Here we have Mean=28.3333

and Median=28.5

Hence, the correct option is: option: a

a .mean or median because there is no outlier.

Irrational equations 64^1/3 how to simplify?

balandron [24]

For indicies, the numerator is the normal power, and the denominator is a root as such. So 1/2 would be square root, 1/3 would be cube root, 1/4 would be 4th root and so on.

So, 64^(1/3) is the third root of 64, which is equal to 4.

What is limit of (x cubed 3 x squared 4 x minus 12) as x approaches negative 3? –78 –24 30 54

Sergio039 [100]

The limit of the expression as x approaches -3 is -24

<h3>How to determine the limit of the expression?</h3>

The expression is given as:

$x^3 + 3x^2 + 4x - 12$

As x approaches -3.

The limit expression becomes

$\lim_{x \to -3} x^3 + 3x^2 + 4x - 12$

Substitute -3 for x in the expression

$\lim_{x \to -3} (-3)^3 + 3(-3)^2 - 4*3 - 12$

Evaluate the expression

$\lim_{x \to -3} -24$

Hence, the limit of the expression as x approaches -3 is -24

An article measured speeds of vehicles on several roads in the state of Kansas. On South Cedar Niles, 73 vehicles were observed,

kifflom [539]

Answer:

The sample supports the hypothesis that more than half of the vehicles in South Cedar Niles exceed the speed limit.

p-value = 0.00092

Step-by-step explanation:

To solve this problem, we run a hypothesis test about the population proportion.

Proportion in the null hypothesis $\pi_0 = 0.5$

Sample size (n) = 73

Sample proportion (p) = 49/73 = 0.6712

H0: $\pi_0 = 0.5$

Ha: $\pi_0 \geq 0.5$

Test statistic = $(p - pi)\sqrt{n} / \sqrt{\pi_0 (1-\pi_0)}$

Calculated statistic = $(0.6712 - 0.5)\sqrt{73} / \sqrt {0.5(1-0.5)} = 2.9255$

p-value = 0.00092

Since, p - value is less than or equal to 0.05, the null hypothesis must be rejected. The sample supports the hypothesis that more than half of the vehicles in South Cedar Niles exceed the speed limit.

What is the midpoint of a line segment with the endpoints (8,-3) and (-5, -9)?

Elina [12.6K]

Answer:

(1.5, -6)

Step-by-step explanation:

$(\frac{8-5}{2}=x)=(\frac{3}{2}=x)=(1.5=x)$

$(\frac{-3-9}{2}=y)=(\frac{-12}{2}=y)=(-6=y)$

(1.5, -6)
