The average height of a basketball player for the WNBA is 72 inches tall, and the median height is 5'11". The average height of
Assoli18 [71]

Answer:

The difference in the median is 8 inches, therefore it is higher than the difference in the mean which is 7 inches.

Step-by-step explanation:

In order to solve this question we first need to calculate the difference between the median and the average on both leagues. We have:

mean dif = mean NBA - mean WNBA

mean dif = 79 - 72 = 7 inches

median dif = median NBA - median WNBA

median dif = 6'7'' - 5'11" = (6*12 + 7") - (5*12 + 11") = 79" - 71" = 8 inches

The difference in the median is 8 inches, therefore it is higher than the difference in the mean which is 7 inches.

Describe the difference between a probability derived from the analytic view (logical analysis), the Relative Frequency view (sa
oee [108]

Answer:

See the explanation

Step-by-step explanation:

<h2>Analytic View:</h2>

If and event can occur in A number of way and fail in B number of ways, then probability of its occurrence is:

P(A)= \frac{A}{A+B}

or probability of its failing is:

P(B)=\frac{B}{A+B}

<h3>Example:</h3>

Rolling a number smaller than 3 in a dice.

A= 2 (1,2)

B = 4 (3,4,5,6)

P(A)= \frac{2}{2+4}=\frac{1}{3}

<h2>Relative Frequency View:</h2>

Definition of Probability in terms of past performances (data). It can be taken as how often things happens divided by all outcomes.

<h3>Example:</h3>

A batter has 50 safe hits at 200 bats, which makes his batting average \frac{50}{200}= 0.25 which is the probability.

<h2>Subjective View:</h2>

When you define a probability due to personel beleif in the likelihood of an outcome. It involve no formal calculations and varies from person to person, depending on their past experience.

<h3>Example:</h3>

A person beleives that probability that the batter will hit safely in the next bat is 0.75

Answer:

the inequality is y>2x+1

I figured this out because watching the video showed me how to find the slope I first found my y-axis point then went down, knowing the symbol would be < I kept that in mind when I went to look for my x-axis after that put the two points into slope-intercept formula.

Leon had to buy fences, 1 yard fences would be 2$. He had to buy more yards of fences than the total he was looking for. the y-axis would be how much he spent and the x-axis would be the yards for the fences.

The answer would be B.

Add across : x + 6x = 7x

(x + 1) + (x + 5) = 2x + 6

So you get 7x / 2x + 6
