Find the mean median and mode of the data set round to the nearest tenth 15,13,9,9,71,11,10,13,1,13

ser-zykov [4K]

Answer:

Organize: 1, 9, 9, 10, 11, 13, 13, 13, 15, 71

Mean: 16.5

Median: 12

Mode: 13

Step-by-step explanation:

Mean (average): 1+9+9+10+11+13+13+13+15+71 = 165 165/10 = 16.5

10-> how many numbers

Median (middle #): 1, 9, 9, 10, <u>11, 13</u>, 13, 13, 15, 71

(11+13)/2 = 12 <---11 and 13 because there are two middle numbers, so you calculate the average of those two #s

Mode (most frequent #): 1, 9, 9, 10, 11, <em><u>13, 13, 13</u></em>, 15, 71 --->13 appears the most

lysha is at a local library with her best friend. they've noticed a lot of cute boys in the library, and alysha bets that of the

Annette [7]

Using the binomial distribution, there is a 0.1201 = 12.01% probability that Alysha will win the bet.

<h3>What is the binomial distribution formula?</h3>

The formula is:

$P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}$

$C_{n,x} = \frac{n!}{x!(n-x)!}$

The parameters are:

x is the number of successes.

n is the number of trials.

p is the probability of a success on a single trial.

For this problem, the parameters are given as follows:

n = 20, p = 0.5.

She wins the bet if there are 12 boys, hence the probability is P(X = 12), found as follows:

$P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}$

$P(X = 12) = C_{20,12}.(0.5)^{12}.(0.5)^{8} = 0.1201$

0.1201 = 12.01% probability that Alysha will win the bet.

98. Explain in your own words, how you can tell from its equation whether a parabola opens up, down, left or right.

Nitella [24]

Answer:

The same way you tell if a parabola opens up or down, by the leading coefficient of the variable.

Step-by-step explanation:

Since the x-axis is positive to the right, a positive leading coefficient (3) means it opens to the right. eg. And a negative leading coefficient (-2) means it opens to the left.
