What is the linear equation?

An algebraic equation of the form y=mx+b is referred to as a linear equation. m is the slope, and b is the y-intercept, and all that is involved is a constant and a first-order (linear) term. The variables in the preceding equation are y and x, and it is occasionally referred to as a "linear equation of two variables."

We have,

The equation 4x=3y-7

So, here we can solve this equation for the x as well as y equals,

Firstly we will solve for x:

4x = 3y - 7

dividing the whole equation by 4 we get,

4x/4 = (3y - 7)/4

x = (3y - 7)/4

Similarly, we will solve for y:

4x = 3y - 7

3y = 4x + 7

dividing the whole equation by 3 we get,

3y/3 = (4x + 7)/3

y = (4x + 7)/3

Hence, the given equation can be solved for the value of x and y

i.e. x = (3y - 7)/4 & y = (4x + 7)/3

After updating preferences, the monopolist's probability of obtaining a promising result is P(Promising) = 17/40. So, the answer is option a.17/40

To answer this question, we need to calculate the probability that the firm will obtain a promising result, given that it has updated its preferences.

If the firm chooses not to invest in R&D, its profit is given by:

π0 = (P - C(q))q = (12 - Q - 5 - 6Q)Q = Q(7 - 7Q)

If the firm invests in R&D, its profit is given by:

π1 = P(Promising) [P(Successful) * (12 - Q - 5 - 2Q) + P(Failure) * (12 - Q - 5 - 6Q)] - 4 + [1 - P(Promising)](12 - Q - 5 - 6Q)

where P(Promising) is the probability of obtaining a promising result, P(Successful) is the probability of the new technology being successful, and P(Failure) is the probability of the new technology being a failure.

Simplifying the equation above, we get:

π1 = P(Promising) [3/8 * (7 - Q) + 5/8 * (7 - 5Q)] - Q - 1

To determine whether the firm should invest in R&D or not, we need to compare the profits under the two scenarios.

If π0 > π1, the firm should not invest in R&D. If π0 < π1, the firm should invest in R&D. If π0 = π1, the firm is indifferent between the two options.

Setting π0 = π1, we can solve for Q and obtain the threshold quantity, Q*.

Q* = 9/4

If Q* > 0, the firm will invest in R&D. Otherwise, it will not invest in R&D.

Substituting Q* into the two profit functions, we obtain:

π0 = Q*(7 - 7Q*) = 81/16

π1 = P(Promising) [3/8 * (7 - Q*) + 5/8 * (7 - 5Q*)] - Q* - 1

Substituting the values given in the question, we obtain:

π1 = P(Promising) [21/8 - 3/8Q* - 15/8] - Q* - 1

Simplifying the equation above, we get:

π1 = P(Promising) [-3/8Q* + 6/8] - Q* + 1/8

π1 = P(Promising) [-27/32] - 17/32

Setting π0 = π1, we can solve for P(Promising) and obtain:

P(Promising) = 17/40

Answer:

h = 100

Step-by-step explanation:

plz mark my answer as brainlist plzzzz vote me also

Answer:

100°

Step-by-step explanation:

Ok so it looks overwhelming at first, but you just need to make sections and break it down

You are looking for h°, so you want to make it a triangle

The angles of this triangle would be h°, 40°, and x°

You can find x° by using the 140° on the same line

it is a straight line, so that means its angle is 180°

180° - 140° = 40°

x° = 40 °

so now you know that the angles in the triangle are h°, 40°, and 40°

Every triangle has angles that measure to 180°

180° - 40° - 40° = 100°

h° = 100°

The area of the circle on the paper is 4.5 cm when traced around the edge of the quarter on a sheet of paper.

The area of the circle is equal to the product of the square of the radius of the circle and pi.

A = πr²

where 'r' is the radius of the circle

The diameter of a quarter is 2.4 cm. You trace around the edge of the quarter on a sheet of paper.

The area of the circle on the paper = πr²

Here r = (diameter of a quarter)/2 = 2.4/2 = 1.2 cm

The area of the circle on the paper = π(1.2)²

The area of the circle on the paper = π × 1.44

The area of the circle on the paper = 4.5238

Round the answer to the nearest tenth.

The area of the circle on the paper = 4.5 cm

Thus, the area of the circle on the paper is 4.5 cm

Answer:its 4.5

Step-by-step explanation:

The statement is true. A confidence interval is a statistical range that is used to estimate the unknown population parameter with a positive stage of confidence primarily based on the information accumulated from a pattern of data.

Inside the case of a share, a confidence interval presents a number potential values for the populace percentage, given the pattern share and the sample size, along with the selected stage of confidence.

For instance, if a pattern of 500 people is taken from a population to estimate the percentage of individuals who assist a particular political party, and the pattern share is observed to be 0.6, a 95% confidence interval could offer a number of values among 0.56 and 0.64 as possible values for the population percentage. This variety suggests that we're 95% confident that the actual population share lies within this interval.

Answer:

Youth tickets = $4

Step-by-step explanation:

Let x and y represent the price of adults and youth tickets respectively;

Given;

A youth ticket is half the price of an adult ticket

y = 0.5x ......1

They paid $24 for 2 adult tickets and 2 youth tickets.

2y + 2x = 24 ......2

Substituting equation 1 into 2;

2(0.5x) + 2x = 24

x + 2x = 24

3x = 25

x = 24/3 = 8

Since, y = 0.5x

y = 0.5(8) = 4

Adult tickets = $8

Youth tickets = $4

In binary representation, each bit can be either 0 or 1. Using five binary bits, we can obtain 32 different numbers. Therefore, the correct answer is (B).

With five binary bits, we have five positions, and each position can have two possibilities (0 or 1). To calculate the total number of different numbers we can obtain, we need to raise 2 to the power of the number of bits. In this case, we have \(2^5,\) which equals 32. Therefore, we can obtain 32 different numbers using five binary bits. To understand this concept, we can think of each binary bit as a switch that can be either on (1) or off (0). With five switches, we have a total of 32 different combinations or numbers that can be represented. These numbers range from 0 (all switches off) to 31 (all switches on). Therefore, the correct answer is (B), which states that we can obtain 32 different numbers using five binary bits.

====================================================

Explanation:

We start off with 16 seats in the first row. Then we have 16+3 = 19 seats in the next row and 19+3 = 22 seats in the third row, and so on.

The pattern is this: 16, 19, 22, ...

We add on 3 each time we need to get another row of seats. We keep doing this until we have 25 rows in all.

We need to determine how many seats are in row n, where n is some positive whole number, aka n is a natural number.

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

Going back to the sequence {16,19,22,...} we can see that this is arithmetic because we have the same gap between the adjacent numbers. That gap being 3. This is the common difference, so d = 3.

The start term is a = 16

The nth term is...

f(n) = a + d(n-1)

f(n) = 16 + 3(n-1)

f(n) = 16 + 3n - 3

f(n) = 3n + 13

This function f(n) will quickly tells us how many seats are in a given row.

For instance, if n = 3, then,

f(n) = 3n + 13

f(3) = 3*3 + 13

f(3) = 9 + 13

f(3) = 22

This matches from the third term in {16, 19, 22, ...}. I recommend you try other values of n to help show why that function works the way it does.

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

We did all that work to find the nth term f(n) so that we can then use the formula below to sum all the terms from 1 to n

Sn = sum of the first n terms

Sn = first term + second term + ... + nth term

Sn = (n/2)*(first term + nth term)

Sn = (n/2)*( a + f(n) )

Sn = (n/2)*(16 + 3n+13)

Sn = (n/2)*(3n + 29)

Let's try n = 2 and we get

Sn = (n/2)*(3n + 29)

S2 = (2/2)*(3*2 + 29)

S2 = 35

Then note how the first two terms of {16, 19, 22, ...} add to 16+19 = 35 to help confirm that we have the correct Sn formula.

I should point out that this trick only works for arithmetic sequences.

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

We have one more step from here. Plug in n = 25 to find the sum of the first 25 terms of the arithmetic sequence {16,19,22,...}

Sn = (n/2)*(3n + 29)

S25 = (25/2)*(3*25 + 29)

S25 = 1300

Therefore, this theater has a total of 1300 seats which is the final answer.

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

You could list out all the first 25 terms of {16,19,22,...}, and then add them up, and you should get 1300 as the result. Doing such a check is tedious and often something I recommend you would use computer software for.

I used computer software to get the following

16+19+22+25+28+31+34+37+40+43+46+49+52+55+58+61+64+67+70+73+76+79+82+85+88 = 1300

This confirms the correct final answer. This part is optional in my opinion. It's just there if you're curious. Note how each term in that long sum above is incrementing by 3 each time.

In the given right angle triangle the measure of tanL, sinL, and cosL is 73.74°.

We know a right-angled triangle has three sides they are -: Hypotenuse,

Opposite and Adjacent.

We can remember SOH CAH TOA which is,

sin = opposite/hypotenuse, cos = adjecent/hypotenuse and

tan = opposite/adjacent.

Given, A right-angled triangle has side lengths 7, 24, and 25.

Here, Hypotenuse is 25, Adjacent is 7 and opposite is 24.

Now, tan = opposite/adjacent.

tanL = 24/7.

L = tan⁻¹(24/7).

L = 73.74°.

Similarly,

sinL = 24/25.

L = sin⁻¹(24/25).

L = 73.74°.

And,

cosL = 7/25.

L = cos⁻¹(7/25).

L = 73.74°.

Step-by-step explanation:

The distribution of the given function is a uniform distribution.

A strictly increasing function is the one which increases continuously in a given interval. If f-1(u) is a strictly increasing function of u, then the distribution of f-1(u) is the same as that of u. This is because a strictly increasing function preserves the rank ordering of its input, so if u-1 and u-2 are two random variables with a uniform distribution on the interval (0,1), then the rank order of f-1(u-1) and f-1(u-2) will be the same as the rank order of u-1 and u-2. Since the uniform distribution is defined by the rank order of its values, this means that the distribution of f-1(u) is also uniform on the interval (0,1).

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

7 + 3^2-2x5÷4-1x2 and (¾+ ⅛) ÷ ⅛ - 2^2

Express the exponents properly

This gives

7 + 3² -2  * 5 ÷ 4 - 1 * 2 and (¾+ ⅛) ÷ ⅛ - 2²

Evaluate the exponents

So, we have the following representation

7 + 9 - 2 * 5 ÷ 4 - 1 * 2 and (¾+ ⅛) ÷ ⅛ - 4

Evaluate the expressions in brackets

So, we have the following representation

7 + 9 - 2 * 5 ÷ 4 - 1 * 2 and 7/8 ÷ ⅛ - 4

Solve the products and quotients

7 + 9 - 2.5 - 2 and 7 - 4
