What is the difference between the values of I-10| and 19| ?

The indicated probability P(x >43) of the random variable x normally distributed is 0.8414.

Abraham de Moivre, a Frenchman, was the first to recognize the normal distribution (1667-1754). The curve was later developed further and its equation was developed by Carl Friedrich Gauss (1777–1855); for this reason, it is also more generally referred to as the "Gauss bell" or "Gaussian distribution."

Any point (x) from a normal distribution can be converted to the standard normal distribution using the formula z = (x-mean) / standard deviation (z).

Given:

Mean u = 50

Standard Deviation o = 7

To find the probability P(x>43),

= [tex]P(\frac{x - 50}{7} > \frac{43 - 50}{7} )[/tex]

= [tex]P(z > -1) = 0.8414[/tex]

So, the equation to determine the number of months is 200 + 10x = 0 + 60x.

Let x be the number of months you can belong to each gym for it to cost the same at both places.

The equation to determine the number of months is:

200 + 10x = 0 + 60x

To solve for x, we can subtract 200 from both sides of the equation:

10x = -200

And finally, we divide both sides by 10:

x = -20

Therefore, you can belong to each gym for -20 months for it to cost the same at both places. But since month are positive numbers, x=-20 is not a solution. Therefore, the statement is not true, the cost will never be the same for both gyms.

In a dice, there are 3 even and 3 odd numbers.

So, to calculate the required probability, we will have to calculate the probability of getting an odd number in all of them.

Probability of getting odd number in 1 dice = 3/6 = 1/2

Probability of getting odd number in 4 dice =

1/2 x 1/2 x 1/2 x 1/2 = 1/16

Therefore, probability of getting atleast one even number is 1 - 1/16 = 15/16

The volume of the spherical glass bulb is approximately 14.1 cubic cm.

To find the volume of a spherical glass bulb, we can use the formula for the volume of a sphere:

[tex]V = 4/3 * pi * r^3[/tex]

Where V is the volume, pi is a mathematical constant (approximately equal to 3.14), and r is the radius of the sphere.

We know the diameter of the bulb is 31.5mm and to find the radius of the sphere, we divide the diameter by 2.

So, radius (r) = 31.5mm / 2 = 15.75mm

Now we can substitute this value into the formula for the volume of a sphere:

[tex]V = 4/3 * pi * (15.75mm)^3[/tex]

We can convert the value of radius from mm to cm by multiplying it by 10^-3

[tex]V = 4/3 * pi * (15.75 * 10^{-3})^3[/tex]

Now we can calculate the value of V

V ≈ 14.1 cubic cm

A perpendicular force is applied to a beam. The maximum force is 12 kN. The resulted shear function is S(x) = - 2x²

When a perpendicular force is applied to static material (in this case, a beam), shearing forces occur.

Shearing force is calculated as the algebraic sum of all transverse forces acting on either side of a beam or frame section.

First, look at the ratio between forces (in y-direction) and x.

y/x = 12/3

y = 4x

Let S(x) = shear function.

Applying Newton's first law on y-axis:

∑Fy = 0

S + x · 4x · 1/2 = 0

S + 2x² = 0

Where;

V is volume

r is radius

h is height

We are given;

Radius(r) = diameter/2 = 2.5/2 = 1.25 ft

Height(h) = 5 ft

Thus;

V = π * 1.25² * 5

V = 24.53125 ft³

There are approximately 7.48 gallons of water in a cubic foot, therefore;

#SPJ1

Answer: 183.49 gallons (D)

Step-by-step explanation:

Okay you are trying to find how many gallons of water the water cooler can hold.

So start by using the formula for the volume of a cylinder.

V = πr^2h

First find the radius, which is half the diameter.

The diameter is 2.5 so divide that by 2 to find the radius.

2.5/2 = 1.25

Now that you know the radius, times it by itself:

1.25 x 1.25 = 1.5625

Now multiply 1.5625 by the height, which is 5.

1.5625 x 5 = 7.8125

Now multiply 7.8125 by 3.14

7.8125 x 3.14 = 24.53125

And finally, multiply 24.53125 by 7.48

24.53125 x 7.48 = 183.49375 gallons

Now round to the nearest hundredth:

183.49 gallons

The value of upper quartile is, 300.

The value of 7th decile is, 250.2.

The value of 35th percentile is, 100.

Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.

We have to given that;

The donations are as follows,

⇒ 50, 50, 50, 100, 100, 100, 150, 150, 200, 250, 250, 300, 300, 400, 500.

Now, We find the values as;

a) The upper quartile is,

⇒ Qₐ = a/4 (n + 1)

Here, n = 15

So, We get;

⇒ Q₃ = 3/4 (15 + 1)

        = 3/4 × 16

        = 12

So, Q₃ is in 12th position.

So, The value of Q₃ = 300

The value of 7th decile is,

⇒ D₇ = 7/10 (15 + 1)

        = 7/10 × 16

        = 11.2

Here, 11.2 is between the position 11th and 12th position which are 250 and 300 respectively.

Then, We get;

⇒ 300 - 250 = 50

Hence, The value of D₇ = 250 + 0.2

                                     = 250.2

Now, The value of 35th percentile is,

⇒ Pₐ = a/100 (n + 1)

⇒ P₃₅ = 35/100 (15 + 1)

         = 35/100 × 16

         = 5.6

Here, 5.6 is between the 5th and 6th position which are 100 and 200 respectively.

Hence,  P₃₅ = 100

This is a condition known as ankylosis, and it describes a situation in which two bones lose their contact with each other.

Ankylosis can result from a variety of causes, including trauma, infection, or degenerative joint diseases. In cases of trauma, the articulating surfaces of the bones can be damaged, leading to a complete absence of contact between the two bones. Similarly, if an infection is present, the cartilage and ligaments of the joint can be destroyed, leading to ankylosis.

Finally, in cases of degenerative joint diseases, such as arthritis, the joint's articulating surfaces can be damaged, leading to a complete loss of contact between the two bones.

The symptoms of ankylosis vary depending on the severity of the condition. In mild cases, the patient may experience stiffness, pain, and reduced range of motion in the joint. In more severe cases, the joint may become completely immobile, and the patient may have difficulty walking or performing other activities.

Membership cost per month = $20

Price of a slice of pizza for members = $2

How much would Alang have to pay the pizza shop if he bought 17 slices of pizza this month?

The total cost of Alang on 17 slices of pizza = membership cost per month + prices of 17 discounted pizza

$20 + $2(6) = $32

What would be the monthly cost for a slice of pizza

The monthly cost of Alang a slice of pizza = membership cost per month + price of 1 discounted pizza

$20 + 2 = $22

So,

Alang would have to pay $32 if he bought 17 slices of pizza this month.

The cost of a slice of pizza is $22

Answer:

Since 21 and 22 are vertical angles, they are congruent. Therefore, m/1 = m22.

Using the equation m/1 = (17x + 1) we can find the measure of the angle m22.

m22 = (17x + 1)

Since ZK and ZL are complementary angles, the sum of their measures is 90 degrees.

mZK + mL = 90

Using the equations mZK = (3x + 3) and mL = (10x-4) and substituting them in the equation, we can find the measure of each angle.

3x + 3 + 10x - 4 = 90

13x - 1 = 90

13x = 91

x = 7

Therefore, mZK = (3x + 3) = (3(7) + 3) = 24 and mL = (10x-4) = (10(7) - 4) = 66
