This question is incomplete, the complete question is;

Given that is a standard normal random variable, find for each situation (to 2 or 3 decimals)

a. The area to the left of z is 0.8

b. The area to the left of z is 0.882

c. The area to the right of z is 0.8225

(Hint: Enter the positive z-value)

Answer:

a) z = 0.84

b) z = 1.185

c) z = -0.925

Step-by-step explanation:

a)

area to the left of z is 0.8

Making use of the standard normal table

p( Z < z ) = 0.8

we check the the probability of 0.8 in the standard normal table

so the corresponding value of z is 0.84

p( Z < 0.84 ) = 0.8

z = 0.84

b)

area to the left of z is 0.882

Making use of the standard normal table

p( Z < z ) = 0.882

we check the the probability of 0.882 in the standard normal table

so the corresponding value of z is 1.185

p( Z < 1.185 ) = 0.882

z = 1.185

c)

area to the right of z is 0.8225

Making use of the standard normal table

p( Z > z ) = 0.8225

1 - p( Z < z ) = 0.8225

p( Z < z ) = 1 - 0.8225

p( Z < z ) = 0.1775

p( Z < -0.925 ) = 0.1775

z = -0.925

Solution

The quadratic equation is

\(\sqrt{5} +1-\sqrt{5} =1\).

First, let's define an irratinal number. Irrational numbers are all numbers that can't be expressed as the fraction of 2 integers.

Let's make the result be 1, for this, we form the following equation:

\(\sqrt{5} +x=1\)

\(x=1-\sqrt{5}\)

\(\sqrt{5} +(1-\sqrt{5} )=\\ \\\sqrt{5} +1-\sqrt{5} =\\ \\1\)

\(\sqrt{5} +1-\sqrt{5} =1\).

The value of the variable a in the equation is a = 10

A linear equation is any equation with a constant rate

The equation is given as

5(a - 5) = 25

Open the brackets in the above equation

So, we have the following equation

5a - 5 * 5 = 25

Evaluate the products in the above equation

So, we have the following equation

5a - 25 = 25

Add 25 to both sides of the equation

So, we have the following equation

5a - 25 + 25 = 25 + 25

Evaluate the sum in the above equation

So, we have the following equation

5a = 50

Divide both sides by 5

So, we have

5a/5 = 50/5

Evaluate the quotient

a = 50/5

Evaluate the quotient

a = 10

Hence, the solution to the equation is a = 10

x² + (y - 3)² = 36; x² + (y + 8)² =36 represent the circles that have a diameter of 12 units and a center that lies on the Y axis.

We know that the abscissa of coordinates of a point on Y axis is 0.

So the equation of a circle center at (0, k) and radius 'r' is given by,

x² + (y - k)² = r²

Here given that the diameter of the circle must be = 12 units

So the radius of the circle = 12/2 = 6 units.

So the equation of the required circle looks like

x² + (y - k)² = 6², where k is an real number.

x² + (y - k)² = 36

So we can see that the equations x² + (y - 3)² = 36; x² + (y + 8)² =36 can be the equation of the required circle.

The circumference of a circle with one-third the curvature of a circle of radius 1 is 18.85 units

What is circumference ?

The perimeter of a circle is known as its circumference. It is the length of the circle's whole perimeter. The diameter of a circle and the constant are multiplied to get the circumference of the circle. This measurement of a circle's circumference is necessary for someone to cross a circular park or for a circle-shaped table to have a border. The units of the circumference are the same as the units of length and it is a linear value.

If a circle has a radius of 1,

the curvature is inversely proportional to this

So, the curvature= 1

A circle with a curvature of 1/3 :

radius=3

Thus, the circumference of the circle  =  2 *π * radius

                                                               =  2*π * 3

                                                               =  6π

                                                               ≈ 18.85 units

Step-by-step explanation:

You can't add them together because they don't have the same denominator so you multiply 2/3 by 4/4 and 3/4 by 3/3. The result is 8/12 and 9/12, you add it together to get 17/12. 17/12 is an improper fraction, if you want you can change it into a mixed fraction which is 1 5/12.

The vertex of the given equation is (0,12) and (1, -10). The value of y-intercept will be -12.

Given equation :

y=(x−2)2−8

y = 2x - 4 - 8

= 2x - 12

The final equation is y = 2x - 12.

Compare this equation with slope and y-intercept formula :

y = mx+c

So that c = -12

The value of y-intercept according to the solution is -12.

To find the vertex. Let's assume x=0; Substitute in the equation

y = 2(0) -12

y = -12

The first vertex will be (0, -12)

If x = 1; y = 2(1) -12

y = -10

Then the second vertex will be (1, -10).

Hence, the vertex of the given equation is (0,12) and (1, -10). The value of y-intercept will be -12.

The total distance covered is 15000 m. The total time taken is 5220 seconds and the speed is 2.87 m/s.

We know that speed has to do with the ratio of the distance that has been covered to the time taken. The speed is a scalar quantity and as such we do not consider the direction hence we would not consider that going back in the opposite direction. The total distance can be obtained algebraically.

The total distance that the student travelled can be obtained from;

5000 m + 5000 m + 5000 m

= 15000 m

The total time taken in seconds = 1800 seconds + 1800 seconds + 1620 seconds

= 5220 second

Speed = Distance/ Time

= 15000 m/5220 second

Answer:

  (a)  m = 0.47, b = 154.30

  (b)  b = fixed costs, listed as insurance and car payments.

Step-by-step explanation:

(a) All you're required to do here is recognize that the fixed costs of $154.30 for insurance and car payments represent the constant part of the monthly expense. And, the $0.47 per mile represents the mileage-related part of the monthly expense. Of course the mileage-related charge is the product of the per-mile charge ($0.47) and the number of miles (x).

Then the monthly charge is ...

  monthly cost = mileage-related cost + constant (fixed) cost

  y = mx + b

  y = 0.47x + 154.30   ⇔   m = 0.47, b = 154.30

__

(b) The 'b' in the equation is the fixed monthly cost: $154.30 for insurance and car payment.

\(\Large \boxed{0.40 < 0.430 < 0.480 < 0.489}\)

Step-by-step explanation:

First you have to see the decimal places.

Than the number of digits there is.

So this is how we make it from least to greatest!

Since there is 3 numbers after the decimals in almost all of them...

Than let’s make ‘0.40’ into 3 numbers after the decimal too.

I am sure you have heard that if you add a ‘0’ to a decimal nothing will change right?

So let’s make 0.40 into 3 numbers after the decimal just like the other numbers!

Okay so first let’s add a zero to ‘0.40’... which now this turns into ‘0.400’

Now it will be more easier to compare least to greatest!

0.400 is the least, than comes 0.430, & than would be 0.480, & finally the greatest would be 0.489

Therefore the answer is 0.40 < 0.430 < 0.480 < 0.489.

For the inequalities y > 3x - 5 and y < -x - 1 the points of solution set is (1,-2).

What is an inequality?

In Algebra, an inequality is a mathematical statement that uses the inequality symbol to illustrate the relationship between two expressions. An inequality symbol has non-equal expressions on both sides. It indicates that the phrase on the left should be bigger or smaller than the expression on the right, or vice versa.

The given inequalities are -

y > 3x - 5

y < -x - 1

Write both the inequalities in equation form -

y = 3x - 5 ..... (1)

y = -x - 1 ....... (2)

Substitute the value of y in equation (1) -

y = 3x - 5

-x - 1 = 3x - 5

-x - 3x = -5 + 1

-4x = -4

x = 1

Substitute the value of x in equation (1) -

y = 3x - 5

y = 3(1) - 5

y = -2

Therefore, the graphs of inequalities intersect at (1,-2).

Answer: 23.94 cm

Step-by-step explanation: I am totally not sure if this is the answer, but think of it this way: Those are 2 semi circles. The formula for the area of a semi circle is A = π * r^2 / 2. For the semi circle with 6 cm, the radius is 3. So we can plug it in the formula. 3.14 * 3^2 / 2, which is 14.13. For the semi circle with 5 cm, the radius is 2.5. Again plug it in and it will be 3.14 * 2.5^2 / 2, which is 9.8125. Then, to get the total area, add the 2 final values together. 9.8125 + 14.13, which is 23.9425. Then it said "round to the nearest hundredth if necessary. We can round to the nearest hundredth, which is 23.94, so that would be the answer. That is just my thought process.

I am not really sure if it's the answer, but take a gander at my thought process and hopefully, you can agree with me.
