The probability that in tonight's game he misses for the first time on his 6th attempt = 0.2244

What is Probability?

A probability is a numerical representation of the likelihood or chance that a specific event will take place. Both proportions ranging from 0 to 1 and percentages ranging from 0% to 100% can be used to describe probabilities.

The Probability that the basketball player made a foul shot = 0.66 or 60%

Then the probability of good shot is = 1-0.66

= 0.34

probability that in tonight's game he misses for the first time on his 6th attempt = (1-p) 5(p)

= ( 1- 0.34)⁵ (0.34)

= 0.2244

Step-by-step explanation:

We know that Julian has $8.75 using mathematical operations.

A mathematical "operation" is the process of calculating a value utilizing operands and a math operator.

The supplied operands or integers must adhere to a set of predefined rules that are connected to the symbol of the math operator.

The five basic operations in mathematics are addition, subtraction, multiplication, division, and modular forms.

So, we know that:

Juan has $3.50.

Julian has 2½ times Juan.

So, the money Julian has is:

First, calculate 2½:

2½

4+1/2

5/2

2.5 times

The money Julian has is:

3.50 * 2.5

$8.75

Therefore, we know that Julian has $8.75 using mathematical operations.

89.086 milliliters of juice will be in a glass with 7 ice cubes.

A branch of mathematics known as algebra deals with symbols and the mathematical operations performed on them.

Variables are the name given to these symbols because they lack set values.

In order to determine the values, these symbols are also subjected to various addition, subtraction, multiplication, and division arithmetic operations.

Given:

Equation of line: y = -29 202x + 293.5.

So, for 7 ice cubes i.e., x= 7

The amount of juice is

y= -29.202 (7)+ 293.5

y= -204.414+ 293.5

y= 89.086

The Range of the length of a rectangle having fixed width and area increasing linearly is  = {y ∈ R : c ≠ 0 or y ≠ 0}, and Domain = All real numbers,

An enclosed 2-D shape called a rectangle has four sides, four corners, and four right angles (90°). A rectangle has equal and parallel, opposite sides. Since a rectangle is a two-dimensional form, it has two dimensions: length and width. The rectangle's longer side is its length, while its shorter side is its breadth.

Given:

The width of the rectangle is fixed, and the length is changing.

The line is formed when connected through the graph.

The area of the rectangle = [tex]length\times width[/tex]

So when the width is fixed, the area would increase linearly and directly proportional to length.

Calculate the range of function y = cx,

y = area as shown in the graph, x is the length, and width is constant c.

Range = {y ∈ R : c ≠ 0 or y ≠ 0}

Calculate the domain,

It can be any real number, as the area can't be negative.

Domain = All real numbers.

Therefore, Range = {y ∈ R : c ≠ 0 or y ≠ 0}, and Domain = All real numbers.

The coordinates of P and Q is found using the midpoint formula

The formula is of the form

Y = (y₂ + y₁)/2

solving for P (X, Y) Using points A(2, -1), B(-3, 4)

(X, Y) = ((2 + -3)/2, (-1 + 4)/2)

= (-1/2, 3/2)

solving for Q (X, Y) points A(2, -1), C(-5,-7)

(X, Y) = ((2 + -5)/2, (-1 + -7)/2)

The volume of the liquid in the conical flask is 980 π cm³

What is a Cone?

A cone is a three-dimensional shape in geometry that narrows smoothly from a flat base (usually circular base) to a point(which forms an axis to the centre of base) called the apex or vertex.

The volume of a cone is given by the equation

Volume of Cone = ( 1/3 ) πr²h

where r is the radius of the cone

h is the height of the cone

Given data ,

Let the two cones be A and B

Now , the smaller cone be A

The larger cone be B

The radius of the smaller cone is r = 8 cm

The height of the smaller cone is h = 20 cm

Now , the volume of the smaller cone V = ( 1/3 ) πr²h

Substituting the values in the equation , we get

Volume of cone A = ( 1/3 ) πr²h

Volume of cone A = ( 1/3 ) π x 8 x 8 x 20

Volume of cone A = 426.67 π cm³

Now ,

The larger flask is filled with height H = 20 cm

The radius of the larger cone is R = 14 cm

The height of the larger cone is H = 15 cm

Now , the volume of the smaller cone V = ( 1/3 ) πR²H

Substituting the values in the equation , we get

Volume of cone B = ( 1/3 ) πR²H

Volume of cone B = ( 1/3 ) π x 14 x 14 x 15

Volume of cone B = 980 π cm³

Therefore , the volume of the larger cone B is 980 π cm³

Hence , The volume of the liquid in the conical flask is 980 π cm³

Step-by-step explanation:

When using the distributive property, the number outside the parentheses (12) is "distributed" to each of the values inside the parentheses. In other words, 12 will be multiplied by 3/4 and 2x:

12(3/4 - 2x)

12(3/4) - 12(2x) <----- so now we successfully got rid of the parenthesis. Next, simplify

12(3/4) = 9

12(2x) = 24x

9 - 24x <----this is the final answer since it can't be simplified further

Answer: 0.4

Step-by-step explanation:

The question is asking for the probability to own a dog.

40% own a dog.

If you add all of the percentages you get 100%

40/100

=0.4

The probability is 0.4 times to randomly select a resident that only owns a dog.

Step-by-step explanation:

as you wrote correctly, proportional relationships are in the form

y = mx

that means the line has to go through the origin (0, 0). otherwise it is in the form

y = mx + b

which is still linear but not proportional.

1a.

the rate of change is between 2 points A and B

(Yb - Ya)/(b - a)

in our case e.g. (4, 5.52) and (8, 11.04)

(11.04 - 5.52)/(8 - 4) = 5.52 / 4 = 1.38

when we use other points we get the same result. we see e.g. that when we double x (pounds), then also y (cost) is doubled.

the rate of change is 1.38.

this is also called the slope of the line.

b.

as mentioned in a., when we multiply x by a factor, then y is multiplied by the same factor. it also means that the function contains (0, 0) : for 0 pounds we pay $0.

c.

y = 1.38x

2a.

the slope is (as it is the same as the rate of change) the ratio of (y coordinate change / x coordinate change) when going from one point on the line to another.

we try to find points with integer coordinates to do that.

I see e.g. (3, 4) and (6, 8).

x changes by +3 (from 3 to 6).

y changes by +4 (from 4 to 8).

so, the slope is +4/+3 = 4/3.

b.

the simplest indicator is that the line goes through the origin (0, 0), which it does.

c.

y = (4/3)x
