The expected value (EV) of T1 is 1/λ, and the variance (Var) of T1 is 1/λ^2, where λ is the rate parameter of the exponential distribution.
How to calculate the EV and Var of T1 for an exponentially distributed random variable with fr(t) = 7e^(-4t)?Given that T1 is exponentially distributed with a probability density function fr(t) = [tex]7e^(-4t),[/tex] we can calculate the expected value (EV) and variance (Var) of T1.
To find the EV, we integrate the product of t and fr(t) over the range of possible values of T1
EV[T1] = [tex]∫ t * fr(t) dt = ∫ t * 7e^(-4t) dt[/tex]
Using integration by parts, we can find that EV[T1] =[tex][t * (-7/4)e^(-4t)] - ∫ (-7/4)e^(-4t) dt[/tex]
Simplifying further, EV[T1] = [-7t/4 * e^(-4t)] - (7/16) * e^(-4t) + C
Evaluating this expression over the range of possible values of T1 (from 0 to infinity), we find that EV[T1] = 4/7.
To calculate the variance, we can use the formula Var[T1] =[tex]E[(T1 - EV[T1])^2].[/tex]
Varhttps://brainly.com/question/30034780?referrer=searchResults
Plugging in the value of EV[T1], we have Var[T1] = [tex]∫ (t - 4/7)^2 * 7e^(-4t) dt[/tex]
Simplifying and evaluating this integral, Var[T1] = 8/49.
Therefore, the expected value of T1 is 4/7 and the variance of T1 is 8/49.

When you flip a biased coin the probability of getting a tail is 0.47. Find the probability of getting a head.
Answer:
0.53
Step-by-step explanation:
1 - 0.47 = 0.53
Answer: 0.53
Answer:
0.53 or 53%
Step-by-step explanation:
1 = 100%
1 - 0.47 = 0.53 * 100 (100%) = 53% chance of getting heads.
Olympics sports has a markup of $66 on a pair of sneakers. if this is a 37% markup on selling price, find the selling price and the cost as a percent of the selling price.
Mark up = $66
Mark up on selling price = 37%
Selling price = 37%
Selling price x Mark up percentage = Mark up
Selling price x 37% = 66
Selling price = $178.38
Cost = Selling price - Mark up
= 178.38-66
= $112.38
Cost as a percentage of selling price = Cost / Selling price
= 112.38/178.38
= 63%

According to a survey, 15% of city workers take the bus to work. Donatella randomly surveys 10 workers. What is the probability that exactly 6 workers take the bus to work
By using Binomial Distribution the probability that exactly 6 workers take the bus to work is 0.001.
What is Binomial Distribution?When every experiment shares the probability of achieving a given value, the number of trials or observations is summarised using the binomial distribution.
The likelihood of observing a specific percentage of successful occurrences in a specific number of trials is determined by the binomial distribution.
The formula for binomial distribution is-
[tex]P(X=x)={ }^{n} C_{k} p^{k}(1-p)^{n-k}[/tex]
'p' is the probability of success,
(1-p) is probability of failure,
'n' is the number of workers,
'k' is number of given workers.
According to the question,
Calculate the probability of success as;
[tex]p=\frac{15}{100}=0.15[/tex]
The, the probability of the failure becomes;
[tex](1-p)=1-0.15=0.85[/tex]
Put above two value in formula of binomial theorem to get the value.

Given growth of population of protozoa 0.469 per member per day and population in beginninng is 5 members.
We have to find the population afte eight days.
First of all we have to find the function or equation showing sum of population after t days.
Because it is given that the rate is 0.469 per member per day it means it is like compounding.
The equation which shows the sum after compounding is P[tex](1+r)^{n}[/tex]
where P is the amount in beginning, r is the rate and n is the number of years.
In this problem the equation will be 5[tex](1+0.469)^{t}[/tex] where t is number of days.

Answer:
[tex]\sf x = \dfrac{n - 2mp}{2m}[/tex]
Step-by-step explanation:
[tex]\sf 3m = m + \dfrac{n}{p + x}\\[/tex]
[tex]\sf 3m - m = \dfrac{n}{p +x}[/tex]
[tex]\sf 2m = \dfrac{n}{p +x}[/tex]
Now cross multiply,
2m*(p +x) = n
To open the parenthesis, multiply 2m by p and x.
2mp + 2mx = n
Isolate the term with variable 'x'
2mx = n - 2mp
Now, isolate 'x', by dividing both sides by 2m
[tex]\sf x = \dfrac{n-2mp}{2m}[/tex]
Answer:
x = [tex]\frac{N-2MP}{2M}[/tex]
Step-by-step explanation:
3M = M + [tex]\frac{N}{P+x}[/tex] ( subtract M from both sides )
2M = [tex]\frac{N}{P+x}[/tex] ( multiply both sides by P + x to clear the fraction )
2M(P + x) = N ← distribute parenthesis on left side
2MP + 2Mx = N ( subtract 2MP from both sides )
2Mx = N - 2MP ( divide both sides by 2M )
x = [tex]\frac{N-2MP}{2M}[/tex]

Mathew's speed of 100 m/min, and the distance of 10 m. east to which he is blown by the wind gives the angle in degrees Mathew is blown off his path as approximately 2.86°.
How can the angle of deflection be found from the given speeds?The given parameters are;
Speed at which Mathew is flying = 100 m/min
Distance and direction in which the strong wind blows him = 10 m. east
Time it takes the wind to deflect Mathew by 10 m. = 2 minutes

Speed and direction of the wind = 10/2 m/min east
Speed and direction of the wind = 5 m/min east
Mathew's flight path can be represented using a vector diagram (please see attached drawing)

What is rectangular prism?A rectangular prism is a polyhedron in geometry that has two parallel and congruent bases. It also goes by the name cuboid. Six faces make up a rectangular prism, and each face has a rectangle shape and twelve edges.
Actually, prisms get their name from the way their faces are shaped. Therefore, a rectangular prism is just a prism with rectangular faces. Although it is a closed, three-dimensional object, two rectangles serve as its foundation.
Calculation for the surface area of rectangular prism-
Height of a rectangular prism => H = 4 inches
Width of a rectangular prism => B = 9 inches
Length of a rectangular prism => L = 3 inches
Surface area of a rectangular prism = 2(LB + BH + HL)

Let [tex]$\boldsymbol{r}_{1}, \ldots, \boldsymbol{r}_{k}$[/tex] be the nonzero rows of [tex]$R$[/tex] starting from the 1st row to the [tex]k[/tex]th row.
Step 1: We want to show that

So [tex]v[/tex] belongs to span{ [tex]$\boldsymbol{r}_{1}, \ldots, \boldsymbol{r}_{k}$[/tex]}
Thus R(R)[tex]\leq[/tex] Span [tex]$\boldsymbol{r}_{1}, \ldots, \boldsymbol{r}_{k}$[/tex]

Which of the following statements about the scatter plot and the line of best fit are accurate? Select all that apply.
Answer:
- There are more points above the line than below
- This is not a line of best fit
Step-by-step explanation:
If we count the data points above and below the line, we can see there are about 4 below and 11 above. This means there are more points above the line than below. Since there are more points above the line than below, this is not a line of best fit.
If you draw a card with a value of three or less from a standard deck of cards, I will pay you $208. If not, you pay me $35. (Aces are considered the highest card in the deck.) Find the expected value of the proposition. Round your answer to two decimal places. Losses must be expressed as negative values.
The expected value of the proposition which is the net expected outcome is; $20.89.
How to find the expected value?We are given that;
There is a deck of cards.
There are 3 kinds of cards that have value under 4 (or equal). These 3 cards are 2, 3, 4 and they are in total 4 * 3 = 12 cards.
The probability that we draw such a card = 12/52 = 0.23.
Thus, the probability that we do not draw such a card = 1 - 0.23 = 0.77.
Now, If we play the game once, we will get 0.23 of the times $208 and 0.77 of the times $35.
Thus, the net total expected outcome is: (0.23*208) - (0.77*35)
= $20.89.

Here is a list of numbers: 13, 15, -6, 8, -16, 2, -12 ,3 ,-18 ,-18 state the median.
The median of list of numbers is-2.
Given the list of numbers is 13,15,6,8,-16,2,-12,3,-18,-18.
The median is the median of a sorted list of numbers. To find the median of a sequence of numbers, the numbers must be sorted in order from lowest to highest or highest to lowest.
Firstly, we will arrange the number from ascending to descending, we get
-18,-18,-16,-12,-6,2,3,8,13,15.
Now, we will find the middle term of the sequence, we get
The middle terms are -6 and 2.
Further, we will find the median of it.
n=(-6+2)/2
n=-4/2
n=-2
Hence, the median of the list of numbers 13, 15, -6, 8, -16, 2, -12 ,3 ,-18 ,-18 is -2.
