Using the binomial probability formula the value of P ( X = 4 ) = 23.04 %.
Given :
Biologists estimate that a baby elk has a 44% chance of surviving to adulthood. Assume this estimate is correct. Suppose researchers choose 7 baby elk at random to monitor. Let X = the number who survive to adulthood. Use the binomial probability formula to find P ( X = 4 ).
here ,
p = 0.44
q = 0.56
Number of trials n = 7
P ( X = 4 ) = C ( n , r ) * p^r * q^n - r
= C ( 7 , 4 ) * 0.44^4 * 0.56^7 - 4
= 35 * 0.44^4 * 0.56^3
= 0.23037
≈ 0.2304
= 0.2304 * 100%
= 23.04 %

which of the following commands is most likely to display the tls handshake between a client and the server at
A widely used security technology called Transport Layer Protection, or TLS, enables privacy and data security for communications over the Internet. Encrypting communication between online applications and servers, such as when web browsers load a webpage, is one of the main applications of TLS.
When a user accesses a website through HTTPS and the browser initially starts to enquire about the website's origin server, a TLS handshake occurs
Together, the client and server will perform the following during a TLS handshake:
Indicate the TLS version (TLS 1.0, 1.2, 1.3, etc.) they'll be using.
Select the cipher suites they'll employ (see list below).
Using the server's public key and the SSL certificate authority's digital signature, confirm the server's identity.
After the handshake, generate session keys to enable symmetric encryption.

Your final grade in a class is based on your score on two tests and the final exam. You scored a 74% and 82% on the tests and an 80% on the final exam
The average grade received on two tests and the final exam is 78.67%
What is average?
The ratio of the sum of the values in a particular set to all the values in the set is the mean value, which is the definition of the average.
The average formula has numerous practical uses. If we were asked to determine the average male height in India or the average age of the men and women in a group, we would add up all the data and divide it by the total number of data points.
Given, the grades in tests are 74% and 82%. Also, the grade on final exam is 80%.
Now, considering that we have to find the average grade in tests and final exams combined, we put the average formula.
Average grade = Sum of percentages of each exam/Total exams
Thus, average is
= (74+82+80)%/3
= 236%/3
= 78.67%

Find the value of the variables in the given parallelogram.
Answer:
x = 58, y = 61
Step-by-step explanation:
We can use two properties of a parallelogram to solve this
1. The opposite angles of a parallelogram are equal
2. The sum of the 4 interior angles of a parallelogram equal 360
Using property 1,
the angle opposite angle y is also y(bottom left)2x + 3 = y + xUsing property 2
(2x - 3) + y + (y + x) + y = 360
3x + 3y + 3 = 360
3x + 3y = 360 - 3 = 357
Divide both sides by 3 to get
x + y = 357/3
x + y = 119 [2]
Add [1] and [2] together to eliminate y and get
x - y + x + y = -3 + 119
2x = 116
x = 116/2 = 58
Use equation [2]
x + y = 119
58 + y = 119
y = 119 - 58
y = 61
If line BG and CF are parallel,then the supplement of BIE = the supplement of GMD. Is this statement correct? Explain your answers
The supplement of BIE equals the supplement of GMD is a false assertion if lines BG and CF are parallel.
Describe the supplement angle.Angles with a supplementary sum are those whose sum is 180 degrees. For instance, the total of angle 130° and angle 50° is 180°, hence they are supplementary angles.
Lines BG and CF are parallel, as shown in the figure.
If BIE = X, then its supplement of BIE will be 180 - X;
similarly, if GMD = Y, then its supplement of GMD will be 180 - Y.
Since BG and CF are parallel, the supplements of BIE and GMD are interior angles on the same side ( as shown in figure)
and for parallel line the interior angle on the same side is 180
so 180 - X and 180 -Y there sum should be 180
They cannot be equal
line BG and CF are parallel, then the supplement of BIE = the supplement of GMD are not equal.

The correct option that describes the vertical asymptote is; B: There is a vertical asymptote at x = 4 because Limit of g (x) as x approaches 4 minus = infinity and limit of g (x) as x approaches 4 plus = infinity
How to find the vertical asymptote of a function?A vertical asymptote of a graph is defined as a vertical line x = a where the graph tends toward positive or negative infinity as the inputs approach a.
A vertical asymptote is a value of x for which the function is not defined, that is, it is a point which is outside the domain of a function;
In a graph, these vertical asymptotes are given by dashed vertical lines.
An example is a value of x for which the denominator of the function is 0, and the function approaches infinity for these values of x.
We are given the function;
g(x) = 2(x + 4)²/(x² - 16)
Simplifying the denominator gives;
(x² - 16) = (x + 4)(x - 4)
Thus, our function is;
g(x) = 2(x + 4)²/[(x + 4)(x - 4)]
(x + 4 ) will cancel out to give;
g(x) = 2(x + 4)/(x - 4)

You win an online auction for a toy. Your winning bid of $30 is 60% of your maximum bid. How much more were you willing to pay for the toy than you actually paid?
Answer:
I was willing to pay $20 more for the toy than I actually paid.
Step-by-step explanation:
Let us take the maximum bid be y
So,
(y × 60) ÷ 100 = 30
60y/100 = 30
60y/100 × 100 = 30 × 100
60y = 3000
60y/60 = 3000/60
y = 50
60% of $50 is $30
So,
50 - 30 = 20
Thus, I was willing to pay $20 more for the toy than I actually paid.

how long until the purchase is paid offthe total amount paidthe cost of using the credit carda. Payoff timeIf the balance is reduced by $21.45 per month, it will take ...
$650/($21.45/mo) ≈ 30.3 months
to pay off the balance.
Joe will be making payments for 31 months.
b. Payoff amountThe total amount Joe pays for his sound system is the sum of its initial cost and the total of interest payments. That sum is ...
cost + interest = total paid
$650 +168.32 = $818.32
Joe will pay a total of $818.32.
c. Credit chargesThe total amount of interest Joe pays is $168.32.

Find the value of k given that both points lie on a line passing through the origin. (−12,−2) and (k, 8)
Using the slope, the required value of k is 48.
What is the slope?In mathematics, the steeper direction of a line is overall processed by the slope or gradient of the line.
A line's slope can be used to determine how steep it is.
Theoretically, the gradient is calculated as "rise over run" (change in y divided by change in x).
Given is a line that crosses through the origin:
y = mx
Let,s take x = -12 and y = -2.
y = mx
-2 = -12m
m = -2/12
m = -1/6
m is the slope.
The equation now:
y = mx
y = -1/6x
Now, insert:
x = k and y = 8
y = mx
8 = -1/6x
x = 6*8
x = 48
Therefore, using the slope, the required value of k is 48.

How to interpret Polynomial Graphs?In polynomial graphs, we know that the roots are the points where the graph crosses or touches the x-axis.
In this given graph, we see that the graph touches the x-axis at x = 5 and then crosses the x-axis at x = -2. Thus;
The roots of the equation are -2 and 5.
However, when the graph changes sign at a point on the x-axis, it means that point represents double roots. Thus, we will now have three roots which are -2, 5 and 5. The factors of the polynomial are;
(x + 2), (x - 5)²
Now, we see that when x = 0, y = 100 from the graph. Thus;
a(0 + 2)(0 - 5)² = 100
a(50) = 100
a = 100/50
