Step-by-step explanation:

Answer:

Step-by-step explanation:

No pressure. You just need to look for the number that when added to the other given number, will give the same as the sum on the other side.

For instance, The top-left question:

4+6 = x+8  (let x be the box)

x= 4+6-8

x=2.

OR, since 4 + 6 =10,

you look for a number when added to 8, that gives 10.

That number is 2.

Hope this helps :]

Answer:

Step-by-step explanation:

To find the inverse of a function, we need to switch the x and y values and solve for y (or x, depending on how the original function is written). The inverse of the function f(x) = 3x + 7 is written as f^-1(x). To find f^-1(x), we can follow these steps:

Replace the function f(x) with y to make it easier to manipulate: y = 3x + 7.

Swap the x and y variables: x = 3y + 7.

Solve for y:

Subtract 7 from both sides to get x - 7 = 3y.

Divide both sides by 3 to get (x - 7) / 3 = y.

Write the inverse function using f^-1(x) instead of y:

f^-1(x) = (x - 7) / 3

So, the inverse of the function f(x) = 3x + 7 is f^-1(x) = (x - 7) / 3.

By using the continuous interest formula, we get 8.54 years that the amount will take to double itself.

The continuous interest formula is used to calculate the future value of a compound interest investment. It is written as follows:

Future Value = Principal × [tex](1 + r)^{n}[/tex]

where Principal is the original investment, r denotes the yearly interest rate, and n denotes the number of compounding periods.

The continuous interest formula is used to compute the future worth of an investment given its current value, yearly interest rate, number of times the interest is compounded each year, and number of years held.

In the given question,

A = A_0[tex]e^{rt}[/tex]

2A_0 = A_0[tex]e^{rt}[/tex]

2 = [tex]e^{rt}[/tex]

ln(2) = rt

t = [tex]\frac{2}{r}[/tex]

t = [tex]\frac{2}{0.08}[/tex]

t = 8.54 years

The circumference of the circle is 110 m.

Let us assume that the wire has been cut into two equal halves thus the radius of the circle would be 35 m/2 = 17.5 m

Then;

C = 2πr

C = circumference

r = radius

"pi" is a mathematical constant approximately equal to 3.14 and "r" is the radius of the circle. If the diameter of the circle is known, the radius can be calculated by dividing the diameter by 2.

C = 2 * 3.142 * 17.5

C = 110 m as we can see here

The solution of x in the rhombus is 3

From the question, we have the following parameters that can be used in our computation:

The rhombus

Also, we have

LN = 14

AN = x + 4

Using the above as a guide, we have the following equation:

LN = 2 * AN

substitute the known values in the above equation, so, we have the following representation

2 * (x + 4) = 14

Evaluate the expression

x + 4 = 7

Subtract 4 from both sides

so, we have the following representation

x = 3

Hence, the solution is 3

If a TCP receiver advertises a window size of 6,353 bytes, and with a link transmission rate 10 Mbps an end-to-end propagation delay of 14.4 ms, then the utilization is 0.4%.

What is Round trip time?

The round-trip time (RTT) is the time it takes from when a browser submits a request to when it receives a response from a server, measured in milliseconds.

The time it takes for a segment to be transmitted over the link is:

time per segment = 1,126 bytes / 10 Mbps = 0.00009008 seconds

The end-to-end propagation delay is 14.4 ms, or 0.0144 seconds.

The time it takes for an ACK to be sent back from the receiver is the propagation delay plus the time it takes for the ACK segment to be transmitted over the link:

time for ack = 0.0144 seconds + (1 segment / 10 Mbps) = 0.014508 seconds

The time it takes for the sender to receive an ACK after sending a segment is the time it takes for the segment to be transmitted, plus the time it takes for the ACK to be sent back:

round trip time = time per segment + time for ack = 0.00009008 + 0.014508 = 0.0145

The number of segments that can be in flight at any given time is the window size divided by the segment size:

segments in flight = 6,353 bytes / 1,126 bytes = 5.645 segments

We can now calculate the maximum sending rate of the sender by dividing the number of segments in flight by the round-trip time:

max sending rate = segments in flight / round trip time = 387.165 segments per second

The utilization of the link is the sending rate divided by the link rate, multiplied by 100 to get a percentage:

utilization = (max sending rate / 10 Mbps) * 100 = 0.00387165 * 100 = 0.387165%

Rounding to one decimal place, the utilization is 0.4%.

Answer: Balu originally had 40 sweets.

Step-by-step explanation:

Let x be the number of sweets Balu originally had.

After Amal gives one third of his sweets to Balu, Balu's number of sweets becomes x + (1/3)x = (4/3)x.

After Balu gives one third of his sweets to Chandran, Chandran's number of sweets becomes 40 + (1/3)(4/3)x = 40 + (1/3)x.

After Chandran gives one third of his sweets to Amal, Amal's number of sweets becomes (2/3)x + (1/3)(40 +(1/3)x) = (2/3)x + (1/3)x + 40/3 = (5/3)x + 40/3.

Since all three of them now have the same number of sweets, we can set the number of sweets each of them has equal:

(4/3)x = (5/3)x + 40/3.

Now, we will isolate x by rearranging the equation. Subtracting (5/3)x from both sides, we get:

(4/3)x - (5/3)x = 40/3

Simplifying the left side:

-x/3 = 40/3

Dividing both sides by -1/3:

x = 40

Thus, Balu originally had 40 sweets.

The time JBLM will you be the closest to Mt. Rainier will be 5.12 minutes.

A measurement of the distance between two places along a line or line segment.

The plane's flight route follows the line.

y = -125/135x = -25/27x

The direction of the perpendicular line passing across Mt. Rainier is,

y = 27/25(x -56) -40

In standard form, these two equations are,

25x +27y = 0

27x -25y = 2512

The coordinates at the closest approach are the answers to these two equations:

(x, y) = (33912/677, 31400/677)

The Pythagorean theorem (distance formula) states that the distance d from the origin to this point is as follows:-

d = 1256√(2/677) km

The airplane's speed can be used to convert this distance to time:

1256√(2/677) X 60/800 =  94.2√(2/677) ≈ 5.120019 mins

So, 5.12 minutes after leaving JBLM, Mt. Rainier will be the nearest.

Based upon this information, (2) I and III only statements can be proven.

From the given information, we can prove that statement II is true, i.e., BD bisects ABC.

Proof:

Since BD is the perpendicular bisector of ADC, we have AD = CD and ∠ADB = ∠CDB = 90°. Thus, triangles ABD and CBD are congruent (by the hypotenuse-leg congruence criterion), which implies AB = BC and ∠ABD = ∠CBD. Therefore, BD bisects ∠ABC.

However, we cannot prove that statements I or III are true based solely on the given information.

Statement I (BD is a median) would be true if we had additional information that AD = DB = DC, but this is not necessarily true based on the given information.

Statement III (△ABC is isosceles) would be true if we had additional information that AB = BC, but this is not necessarily true based on the given information. In fact, it is only guaranteed that AB = BC if AD = BD = DC, which is not necessarily the case.

Therefore, the correct answer is (2) I and III, only.

The linear equation that passes through the two given points is:

y = (-1/3)*x - 2/3

A general linear equation can be written as:

y = a*x + b

Where a is the slope and b is the y-intercept.

If a line passes through the points (x₁, y₁) and (x₂, y₂) then the slope can be written as:

a = (y₂ - y₁)/(x₂ - x₁)

Here we know that the line passes through (4, -2) and (-2, 0), then the slope is:

a = (0 + 2)/(-2 - 4)= 2/-6 = -1/3

y = (-1/3)*x + b

To find the value of b, we can replace the values of any of the points in the equation, if we use (-2, 0) we will get:

0 = (-1/3)*-2 + b

0 = 2/3 + b

-2/3 = b

The linear equation is y = (-1/3)*x - 2/3

the two negatives become positive

The answer is (a) MX + MY. Whether or not X and Y are independent, we cannot simplify (a) or (b) further.

The mean of X + Y is:

E(X + Y) = E(X) + E(Y)

So the answer is not (a) or (b).

(c) is incorrect because the formula given is only true if X and Y are independent, but no such assumption is given in the problem.

(d) is also incorrect because we cannot simply divide the means by the standard deviations to get the standard normal variables, especially when the variables X and Y have different means.

Therefore, the answer is (a) MX + MY.

Standard Deviation is a measure which shows how much variation (such as spread, dispersion, spread,) from the mean exists. The standard deviation indicates a “typical” deviation from the mean. It is a popular measure of variability because it returns to the original units of measure of the data set.
