The equation in slope-intercept form as y = 2x - 4, where 2 is the slope and -4 is the y-intercept.

The equation y = 2x - 4 can be written in slope-intercept form as y = 2x + b, where b is the y-intercept. To find the slope and y-intercept of the equation, we need to solve for b.

The y-intercept is the point where the line crosses the y-axis. To find the y-intercept, we can set x equal to 0 in the equation to get y = 2(0) - 4. This simplifies to y = -4, so the y-intercept is -4.

The slope is the rate at which the line rises. To find the slope, we can take the coefficient of x, which is 2. So the slope of the equation y = 2x - 4 is 2.

In summary, the slope of the equation y = 2x - 4 is 2 and the y-intercept is -4. We can write the equation in slope-intercept form as y = 2x - 4, where 2 is the slope and -4 is the y-intercept.

c) The probability that at least two of the four selected have earthquake insurance is 0.3660.

We have, some parts of California are particularly earthquake-prone.Suppose that in one metropolitan area, 31% of all homeowners are insured against earthquake damage. Four homeowners are to be selected at random.

Let X denote the number among the four who have earthquake insurance. The probability that the homeowner are insured against earthquake is 0.31. Let S denote a homeowner that has insurance and F denote a homeowner that does not has insurance.

a) For X = 0, {FFFF}

The probability of X = 0

= 0.69x0.69x0.69×0.69

= 0.22667

For X = 1, {SFFF, FSFF, FFSF, FFFS}

P( X = 1) = (0.31 x0.69x0.69×0.69) *4)

= -0.40735116

For X = 2,{SSFF, SFSF, SFFS, FSSF, FSFS, FFSS}

P(X= 2) = (0.31x0.31x0.69×0.69)*6

= -0.27451926

For x = 3,{SSSF, SSFS, SFSS, FSSS}

= (0.31x0.31x0.31x0.69) *4

For X = 4, {SSSS}

P(X= 4) = (0.31 <0.31 x0.31x 0.31)

(b) The most likely value for X is X = 1, since it has large probability comparing with other values.

(c) We have to calculate the probability that at least two of the four selected have earthquake insurance, P(X ≥2)= P(X=2)+ P(X=3) + P(X=4)

So, the value of k that makes the system of equations kx - 5y = 2, 6x + 2y = 7 has no solution is -1.

A system of linear equations has no solution when the equations are inconsistent, which means that there is no set of values for the variables that would make both equations true at the same time.

In the case of the system of equations kx - 5y = 2, 6x + 2y = 7, we can check for consistency by trying to find a unique solution for the system. We can use different methods such as elimination, substitution or Gaussian elimination.

If we use elimination method, we try to eliminate one of the variable from one equation and substitute it in another equation. By adding the two equations, we get: (k + 6)x = 9, which implies that the value of x is x = 9/(k+6).

Now by substituting this value into the first equation we get k*9/(k+6) - 5y = 2

And we can find the value of y by dividing both sides by -5/1: y = (2*(k+6))/(5*k)

Now if we substitute this value of x and y into the second equation:

6x + 2y = 7

We get: 6*(9/(k+6)) + 2*((2*(k+6))/(5*k)) = 7

And if we simplify this equation we get: 9 + 4/(5*k) = 7(k+6)/(k+6)

And that gives us k = -1, which means the system has no solution.

Therefore, the value of k that makes the system of equations kx - 5y = 2, 6x + 2y = 7 has no solution is -1.

Answer:

Step-by-step explanation:

It is Linear

The angle 67.5 degrees is 3 times its complement

Let us assume that the complement of the angle be p degrees.

Given that the measure of the angle is three times its complement.

So, the measure of the angle = 3p

We know that two angles are complementary when their measures add to 90 degrees.

The sum of complementary angles is 90 degrees.

So we get an equation, p + 3p = 90

We solve this equation to find the value of p.

p + 3p = 90

4p = 90

p = 90/4

p = 22.5 degrees

so, the measure of complement of the angle is 22.5 degrees.

And the required angle would be, 3 × 22.5 = 67.5 degrees

Multiplying  (1) by  y and (2) by  x

pxy+qy^2=−26y -----(3)

qx^2−pxy=7x -------(4)

Then adding  equation (3) and  (4), we get,

pxy+qy^2+qx^2−pxy=−26y+7x

qy^2+qx^2=−26y+7x

q(y2+x2)=−26y+7x

q=−26y+7xy^2+x2 --------(5)

Substitute x= -4 and y= -3  into the given system to solve it for "p" and "q". Hence, using  x=−4,y=−3 in  (5)

q = −26(−3) + 7(−4)(−3)^2 + (−4)2

q = 78 −289 + 16 = 5025 =2

The equation pair cannot be solved if the lines are parallel.

Although a system of linear equations typically has a single solution, it occasionally may have infinite or no solutions (parallel lines) (same line). When the graphs cross at a particular point, a system of linear equations has a single solution.

When the graphs are parallel, an equation system with linear components cannot be solved. The graphs of a system of linear equations have an infinite number of solutions.
