Ted is not particularly creative. He uses the pickup line​ "If I could rearrange the​ alphabet, I'd put U and I​ together." The

random variable x is the number of women Ted approaches before encountering one who reacts positively. Determine whether a probability distribution is given. If a probability distribution is​ given, find its mean and standard deviation. If a probability distribution is not​ given, identify the requirements that are not satisfied. Find the mean of the random variable x. Select the correct choice below​ and, if​ necessary, fill in the answer box to complete your choice.

Answer:

No, the sum of all the probabilities is not equal to 1.

Step-by-step explanation:

Given

\begin{array}{ccccc}x & {0} & {1} & {2} & {3} & {P(x)} & {0.001} & {0.007} & {0.033} & {0.059}  \ \end{array}

Required

Determine if the given parameter is a probability distribution

For a probability distribution to exist, the following must be true;

\sum P(x)=1

So, we have:

\sum P(x) = 0.001 + 0.007 + 0.033 + 0.059

\sum P(x) = 0.1

<em>Hence, it is not a probability distribution because the sum of all probabilities is not 1</em>

One of the events at the circus starred Gabriella the Human Cannonball. On Saturday she performed in four shows. Shot from a can
34kurt
Answer: 59.49 meters
In this case, Gabriella flew 4 times with different distance. To answer this question you just need to add all the distance, The calculation would be:

Total distance = distance 1 + distance 2 + distance 3 + distance 4
Total distance = 8.05 meters+ 17.71 meters + 14.38 meters + 19.35 meters= 59.49 meters.

a roller skating rink offers a special rate for birthday parties. On the samr day, a party for 10 skaters cost $107 and a party
olga nikolaevna [1]

Answer:

$119

Step-by-step explanation:

Let

x -----> the number of skaters

y -----> the cost for birthday parties

we have the points

(10,107) and (15,137)

step 1

Find the slope of the linear equation

The formula to calculate the slope between two points is equal to

m=\frac{y2-y1}{x2-x1}

substitute the values

m=\frac{137-107}{15-10}

m=\frac{30}{5}=6\ \frac{\$}{skater}

step 2

Find the equation of the line in point slope form

y-y1=m(x-x1)

we have

m=6\\point\ (10,107)

substitute

y-107=6(x-10)

step 3

Convert to slope intercept form

y-107=6x-60

y=6x-60+107

y=6x+47

step 4

How much would a party for 12 skaters cost?

For x=12 skaters

substitute the value of x in the equation and solve for y

y=6(12)+47

y=\$119
