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>

Does the function satisfy the hypotheses of the Mean Value Theorem on the given interval? f(x) = ln x, [1,7] choose one letter t
inn [45]
ANSWER

B.Yes, f is continuous on [1, 7] and differentiable on (1, 7).

c\approx 3.08

EXPLANATION

The given

f(x) = ln(x)

The hypotheses are

1. The function is continuous on [1, 7].

2. The function is differentiable on (1, 7).

3. There is a c, such that:

f'(c) = \frac{f(7) - f(1)}{7 - 1}

f'(x) = \frac{1}{x}

This implies that;

\frac{1}{c} = \frac{ ln(7) - 0}{6}

\frac{1}{c} = \frac{ ln(7)}{6}

c = \frac{6}{ ln(7) }

c\approx 3.08

Since the function is continuous on [1, 7] and differentiable on (1, 7) it satisfies the mean value theorem.

5t 8=43 whats t.I WILL GIVE 50 POINTS AND IF YOU DONT RECEIVE THE POINTS TELL ME AND I WILL GIVE THEM.PLZ HELP MEEEEEEEEEEEEEEEE
lawyer [7]

==> I can't be sure of the equation.  There's a blank space
        between '5t' and '8', where an operation must be.
       I think the operation is more likely ' + ' (addition).  Brainly usually
       does show the ' - ' if it's subtraction, but goes blank if it's addition.
       Tell you what I'll do:  Since you sound so desperate, and you're being
       so generous with your points,  I'll show you how to figure it out both ways.

----------------------------------------

If it's subtraction:                 5t - 8 = 43

Add  8  to each side:              5t      = 51

Divide each side by  5 :            t     = 51/5

                                                 t     = 10 and 1/5

--------------------------------------------

If it's addition:                         5t + 8  =  43

Subtract  8  from each side:     5t        =  35

Divide each side by  5 :             t        =   7
