(b-2)x = 8

In the given equation, b is a constant. If the equation

has no solution, what is the value of b ?

Step 1

identify

b is a constant, so (b-2) is a constant too.

If the equation has no solution, it is, there is not a value of x to satisfy (b-2)x=8

Step 2

solve for x

This value becomes indeterminate when the denominator takes the value of zero,it is

so , the value of b=2 makes the equation has no solution.

Answer

A) 2

The equation of the circle in standard form is (x + 5)² + (y)² = 9/4.

The general representation of the equation is:

(x-h)² + (y-k)²= r²

Where (h,k) is the coordinates of the center of the circle and r is the radius.  And x and y are the corresponding x and y values of the point the circle passes through

Since we have the coordinate of the center as (-5,0)  and the circle passes through (-5, 3/2). Therefore:

h = -5, k = 0, x = -5 and y = 3/2

Let's put these values in the formula.

(x-h)² + (y-k)²= r²

(-5 - (-5) )² + (3/2 - 0)² =  r²  

(-5 + 5)² + (3/2)²= r²

(0)² + (3/2)²= r²

(3/2)² = r²

r = 3/2

Putting radius, r = 3/2,   h = -5 and k = 0 back into the formula wiil give:

(x + 5)² + (y - 0)²= (3/2)²

(x + 5)² + (y)² = 9/4

Therefore,the standard form of the equation of the circle is (x + 5)² + (y)² = 9/4.

Answer:

Step-by-step explanation:

The wood is (8/9) foot long. If cut into 4 pieces, each piece would be (8/9)/4 foot long.

(8/9)/4

((8/9)(1/4)= 8/36 or 2/9 foot long for each piece.

If he sells all 4 pieces for a total of $10, he will charge $10/4) = $2.50 each.

The probability that the nurse will find the two patients is P =  0.49.

We know that the probability that the nurse finds the client on a particular day is 0.7

So, each time that the nurse goes that a home, that probability is the same and is independent of what happened before.

So if the nurse goes to two houses, the probability that she will find the client on the first home is 0.7

And the probability that she will find the client on the second home is 0.7

Then the joint probability (the product of the two individual ones) is:

P = 0.7*0.7 = 0.49

The hypotenuse of the given right angle triangle is: 50 cm

What is hypotenuse?

In mathematics, the hypotenuse is the longest side of a right angle triangle. It is defined as the standard formula, which states that the square of the hypotenuse is equal to the square of their adjacent sides.

According to the question, to calculate the hypotenuse with the given parameters. First name all the three vertices.

AB = 30 cm; BC = 40 cm; AC = ?

Using standard hypotenuse formula, which states:

AB² + BC² = AC²

⇒ 30² + 40² = AC²

⇒ AC² = 900 + 1600 = 2500

⇒ AC = 50 cm

The measure of the angles 2 and 3 are 70°

What is an angle?

An angle is a figure in Euclidean geometry created by two rays, called the sides of the angle, that share a common termination, called the vertex of the angle. Angles created by two rays are located in the plane containing the rays. Angles also were generated when plane cross. These are known as dihedral angles. An angle defined by two intersecting curves is the angle of the rays lying tangent to the respective curves at their point of junction. Angle can also refer to the measurement of an angle or of a rotation. In the case of a geometric angle, the arc is defined by the sides and is centered at the vertex.

Given, angle 1 = 40°

and, angle 2 = angle 3 = x

In a triangle, sum of angles = 180°

or, m∠1 + m∠2 + m∠3 = 180°

or, 2x = 180-40

or, 2x = 140

or, x = 140/2 = 70°

Hence, the measure of the angles 2 and 3 are 70°

Answer:

y = 2x+4

Step-by-step explanation:

2x - y = -4

We add y on both sides:

2x - y + y = -4 + y

so 2x = -4 + y

We now add 4 on both sides:

2x + 4 = -4 + 4 + y,

so 2x+4 = y,

so y = 2x+4

So intercept for y = 2x+4

The 96th term of the arithmetic sequence (1, -12, -25,.......) is 1234.

We are provided with the arithmetic sequence mentioned below;

1, -12, -25,...........

We know that, the rule to calculate the nth term in an arithmetic sequence is

[tex]a_{n}[/tex] = [tex]a_{1}[/tex] + ( n - 1 ) d                             equation 1

Here, d is the difference between two consecutive terms in the arithmetic sequence , [tex]a_{1}[/tex] is the first term, n is the number of terms and [tex]a_{n}[/tex] is the nth term.

We have,

n = 96

[tex]a_{1}[/tex] = 1

d = -12 -1 = -13

Now, substitute these values in equation 1 i.e, formula of arithmetic sequence and on substituting we will get

[tex]a_{96}[/tex] = 1 + ( 96 - 1 ) ( -13 )

[tex]a_{96}[/tex] = 1 - (95) (13)

[tex]a_{96}[/tex] = 1 - 1235

[tex]a_{96}[/tex] = 1234

So, we can conclude that the 96th term of the arithmetic sequence  is 1234.

Statistically significant results occur in a research data when the difference between two groups is not likely to occur on its own, without the benefit of the independent variable. Statistically significant findings suggest that the researchers' outcomes are unlikely to be a result of chance, and that there is a relationship between the variables under investigation in the larger population.

Two decimals are 0.34, 0.83, and 0.83 and Holland could have used it to make a sum of 2.

A number system is defined as a way to represent numbers on the number line using a set of symbols and approaches. These symbols, which are known as digits, are numbered 0 through 9. Based on the basic value of its digits, different types of number systems exist.

We get x + x = 2x by using x to signify our missing values and the assumption that there are two missing values. We obtain the equation 2x + 0.34 since it is the product of these integers and 0.34; after setting it equal to 2, 2x + 0.34 equals 2.

First, take 0.34 off both sides to get 2x = 1.66. To get x = 0.83, divide both sides by 2 now.

Therefore, the decimals are 0.34, 0.83, and 0.83.

probability | 0.20   0.15   0.05   0.1  0.25  0.1   0.15

If a random variable x has values x₁, x₂, .. ,xₙ with their corresponding probabilities given for each of them P(xₐ), then probability that x ≥ xₐ, for some a = 1, 2, .. , n is,

        P(x ≥ xₐ) = P(xₐ) + P(xₐ₊₁) +...+P(xₙ).

Here we need to find the probability that the random variable x is greater than equal to 5. So we need to add up the probabilities corresponding to the random variables x  ≥ 5.

So here, probability that x ≥ 5 is

P(x ≥ 5) = P(5) +P(10) + P(15) + P(20)

Answer: 72

Step-by-step explanation:

The average is 90.

To calculate the average, you add the grades and divide by the total amount of them. The number of grades is 5. We need to know what value of x satisfies the following equation:

[tex]90 = \frac{96+90+87+95+x}{5}[/tex]

To solve the equation, we first multiply each side by 5, netting:

450 = 96 + 90 + 87 + 95 + x.

Then we subtract each grade from each side.

450 - 378 = 378 - 378 + x

The value of 'x' is highlighted in the box

We need to find the function in slope-intercept form. We thus need the y-intercept and slope. We know there are 38000 gallons in the pool already, so the y-intercept is 38000. The pool drains 12 per minute, so the slope is -12.

y = mx + b
y = -12x + 38000

To find the time it takes to drain the pool, we need to find x where y = 0, so we set the equation to 0 and solve for x.

0 = -12x + 38000
-38000 = -12x
-38000/-12 = -12x/-12
3167 = x

Now, to fill it back up, the y-intercept is 0. We know the slope is 16, so the equation is:

y = 16x

Finally, we need to find 16x = 38000. This is simple enough.

y = 16x
38000 = 16x
38000/16 = 16x/16
2375 = x

Answer:

x = 45, y = 85

Step-by-step explanation:

In this figure we can see a Z-angle, which tells us that x = 45

In a triangle, the sum of the angles is 180 degrees,

so the unknown angle in the triangle is 180 - 45 - 85 = 50

For a straight line, the total angle is 180 degrees,

, so y + x + unknown angle of triangle = 180

since x = 45, and unknown angle of triangle = 50,

y = 180 - 45 - 50 = 85

This can also be seen when you realise that the two parallel lines give an F-angle, which tells us that Y = 85
