The total ways of selecting 6 numbers in 175223510 Ways.

A permutation is an grouping or the combination of items that is drawn from a set of which the placement or an arrangement of the given objects is significant. In the other terms, an arrangement of the items in the specific order is a permutation.

Total number of White balls = 59

Total number of red balls = 35

Way of choosing 5 white balls = ⁵⁹C₅

= [tex]\frac{59!}{54! 5!}[/tex]

=5006386 ways

Way of choosing 1 red ball = ³⁵C₁

=35 ways

Hence Total ways would be =

5006386 * 35 = 175223510 Ways

Hence the total ways of selecting 6 numbers in 175223510 Ways.

The slope of a line perpendicular to the given equation of line is 6.

For the stated question, the equation of the line is given as;

3x + 18y = 10

This can be written as;

y = -3/18 x  + 10/18

y = -1/6 x + 5/9

Comparing with general equation of line in slope intercept form.

y = mx + c

slope m = -1/6

The relation of slope for the two perpendicular lines are-

m x m1 = -1

m1 = -1/(-1/6)

m1 = 6

A parametric representation using spherical-like coordinates for the upper half of the ellipsoid is given by x2 = 9 + -2.25y2 + 0.25z2.

A sphere can be deformed into an ellipsoid by applying directional scalings, or more generally, an affine transformation, to it.

A quadric surface, or surface that can be described as the zero set of a polynomial of degree two in three variables, is an ellipsoid. An ellipsoid among quadric surfaces has one of the two characteristics listed below. Every cross section of a flat surface is either an ellipse, empty, or reduced to a single point (this explains the name, meaning "ellipse-like"). It can be contained in a sphere that is big enough because it is bounded.

Three pairwise perpendicular axes of symmetry intersect at an ellipsoid's center of symmetry, or the

According to our question-

To each side of the equation, add "-9y2".

4x2 + 9y2 + -9y2 + -1z2 = 36 + -9y2

combining similar terms 9y2 + -9y2 = 0

4x2 + 0 + -1z2 = 36 + -9y2

4x2 + -1z2 = 36 + -9y2

To either side of the equation, add "z2".

The total number of tests they can grade in 3 hours are 90.

What is graded test?

Your grade in an exam or written assignment is the letter or number you receive as a mark that represents your level of proficiency.

A graded exercise test (GXT) is a screening tool for determining a person's level of fitness. The test measures the cardiovascular response to exercise in order to assess the participant's capacity for exercise.

Since, the number of minutes in 3 hours is:

= 3 x 60 minutes per hour

= 3 x 60

= 180 minutes

The number of tests that Sam can grade in these 3 hours is therefore:

= ( Number of total minutes / Minutes taken by Sam for 6 tests) x 6 tests

= ( 180 / 24) x 6

= 45 tests

The number of tests that Ben can grade are:

= ( Number of total minutes / Minutes taken by Ben for 5 tests) x 5 tests

= ( 180 / 20 ) x 5

= 45 tests

So, the total number of tests they can grade in 3 hours is:

= 45 + 45

The length of the shadow is changing rate at 2.69 [tex]\frac{ft}{sec}[/tex].

What do you mean by length?

The measurement or size of something from end to end is referred to as its length. To put it another way, it is the greater of the higher two or three dimensions of a geometric shape or object. For instance, the length and width of a rectangle define its dimensions.

According to data in the given question,

We have the given information:

The height of the person is 7 ft.

The person is walking away from the post at a rate of 5ft/sec.

The height of the lamppost is 20ft.

Let the person's distance from the bottom of the light post be x ft.

And his shadow's length is y ft.

Form the similar triangles,

[tex]\frac{x+y}{20}=\frac{y}{7}\\[/tex]

7(x+y) = 20y

7x+7y = 20y

20y-7y = 7x

13y = 7x

y = [tex]\frac{7}{13}x[/tex]

Now, we will differentiating wrt t,

[tex]\frac{dy}{dt}=\frac{7}{13}\frac{dx}{dt}................(1)[/tex]

We know that,

[tex]\frac{dx}{dt}=5\frac{ft}{sec}[/tex]

Putting the value of  [tex]\frac{dx}{dt}[/tex]  in equation (1),

[tex]\frac{dy}{dt}=\frac{7}{13}.5=\frac{35}{13}=2.69\frac{ft}{sec}[/tex]

The dimensions of a right circular cylinder of maximum volume are

[tex]5\sqrt{6}[/tex] and [tex]10\sqrt{3}[/tex].

Given the radius of sphere is 15 cm.

Let's assume radius of right circular cylinder = r

height of right circular cylinder = h.

Since the cylinder is inscribed in the sphere, their centers will coincide. As a result, the height is divided into two equal portions from the sphere's center. Therefore, we can apply Pythagoras' Theorem to get the cylinder's half-height in terms of radius.

[tex]R^2 = r^2 + (h/2)^2[/tex].

[tex]r^2=R^2-h^2/4[/tex]

Volume of cylinder = [tex]\pi r^2h[/tex]

Now we can substitute value of [tex]r^2[/tex] in volume of cylinder.

V =  π*([tex]R^2[/tex] - [tex]h^2[/tex]/4)*h

taking  R = 15 .

V = π*(225 - [tex]h^2[/tex]/4)*h

V = π*225*h - π*[tex]h^3[/tex]/4

For maximum volume we have to do derivative of volume = 0

derivative with respect to h.

V' = π*225 - 3*π[tex]h^2[/tex]/4

V' = 0

π*225 - 3*π[tex]h^2[/tex]/4 = 0

3*[tex]h^2[/tex]/4 = 225

[tex]h^2[/tex] =  75*4

h = [tex]10\sqrt{3}[/tex]

put the value of h in [tex]r^2=R^2-h^2/4[/tex]

[tex]r^2[/tex] = 225 - (300/4)

Answer:

  100°

Step-by-step explanation:

You have two supplementary angles in the ratio 7:2, and you want the measure of their positive difference.

The sum of supplementary angles is 180°. The sum of the ratio units in the ratio 7:2 is 7+2 = 9, so each ratio unit must stand for 180°/9 = 20°.

The difference in ratio units is 7 -2 = 5, so the difference in the angles will be 5·20° = 100°.

The measure of their difference is 100°.

__

Additional comment

The two angles are 7·20° = 140°, and 2·20° = 40°. The difference is 140° -40° = 100°.

The breadth of the confidence interval grows as the confidence level does. The breadth of the confidence interval reduces as the confidence level rises.

Generally speaking, the more information we know on the level of the population parameter, the narrower a confidence interval becomes. As a result, we want to make sure that all of the confidence intervals are as small as feasible. So let's look at the variables that influence the mean's t-interval width.

The margin of error grows as the degree of confidence does because we require a broader interval to improve our level of confidence that the interval includes the population mean.

Because the standard error is reduced as sample size increases, confidence intervals are narrower.

When bananas cost 75 cents per pound over the previous month, the increase was 8%. Today, we notice that the price per pound has increased to 81 cents.

In essence, percentages are fractions with a 100 as the denominator. We place the percent sign (%) next to the number to indicate that the number is a percentage. For instance, you would have received a 75% grade if you answered 75 out of 100 questions correctly on a test (75/100). A value or ratio that may be stated as a fraction of 100 is referred to as a percentage in mathematics. If we need to compute a percentage of a number, we should divide it by its whole and then multiply it by 100. The proportion therefore refers to a component per hundred. Per 100 is what the term percent signifies. The letter "%" stands for it.

The probability of having L greater than Shelia's mean glucose level is 0.03 for L = 144.48.

Sheila's glucose level is shown to have a normal distribution, with a mean of 128 mg/dl and a standard deviation of 8 mg/dl.

L represents the patient's blood test level.

The probability that the mean glucose level, 128 mg/dl, is greater than L is given as 0.03.

To find L,

P(128>L) = 0.03

= 1 - P(128 ≤ L) = 0.03

=P(128 ≤ L) = 0.98

We know that we can find the probability of any normal distribution by converting it to standard form and then checking the p-value.

P(X < x) = Φ[(x - μ)/σ]

μ = mean

σ = standard deviation

=Φ[(L - 128)/8] = 0.98

(L - 128)/8 = 2.06

The ball will need to travel 126 feet since it will be dropped from a height of 6 feet and then bounce 10/11 feet.

A number is split in division, which is a straightforward procedure. The simplest way to conceptualize it is as a set of things being distributed among a set of individuals, as in the example given above. In mathematics, division is the process of dividing a number into equal parts and calculating the maximum number of equal parts that may be formed. For instance, dividing 15 by 3 results in the division of 15 into 3 groups of 5 each.

The sum of all possible values, weighted by the likelihood of each value, constitutes the mean of a discrete probability distribution of the random variable X. Each possible value of X must be multiplied by its probability, P(x), before being added to determine the mean.
