Answer:

1/237.12.

Step-by-step explanation:

The probability of winning the minimum award can be calculated by multiplying the probability of picking 4 numbers correctly from 1 to 51 and then multiplying by the probability of picking 1 number correctly from 1 to 42.

The probability of picking 4 numbers correctly from 1 to 51 is given by the formula:

(number of combinations of 4 numbers from 51) / (number of combinations of 5 numbers from 51)

= (51 choose 4) / (51 choose 5)

= 51! / (4! * 47!) / (51! / (5! * 46!))

= (51 * 50 * 49 * 48) / (5 * 4 * 47 * 46)

= 19600 / 10,946

= 1/5.6 approximately

The probability of picking 1 number correctly from 1 to 42 is given by the formula:

1/42

The final probability of winning the minimum award is given by multiplying the above two probabilities:

1/5.6 * 1/42 = 1/237.12

So, the probability of winning the minimum award is approximately 1/237.12.

What exactly are expressions?

Expressions in mathematics are mathematical assertions that comprise at least two phrases that contain numbers, variables, or both, and are connected by an operator in between. Addition, subtraction, multiplication, and division are examples of mathematical operators. For example, x + y is an expression in which x and y are terms separated by an addition operator. There are two sorts of expressions in mathematics: numerical expressions, which include simply numbers, and algebraic expressions, which contain both numbers and variables.

e.g. A number is 6 more than half of another number, which is x. In a mathematical expression, this proposition is expressed as x/2 + 6. Complex riddles are solved using mathematical expressions.

Now,

as shown in figure the model is shaded uptil 3

and in 1 unit there are 5 total boxes which are divided in 2 parts

Step-by-step explanation:

For the two given graphs, the value for vector equation is obtained as [tex]\vec{w} = 2\vec{u} + \vec{v}[/tex].

What is a vector?

A vector in mathematics is a quantity that not only expresses magnitude but also motion or position of an object in relation to another point or object. Euclidean vector, geometric vector, and spatial vector are other names for it.

From first graph it is seen that -

[tex]\vec{u}= < 1,1 >[/tex] and [tex]\vec{v}= < -1,2 >[/tex]

From second graph it is seen that -

[tex]\vec{w}= < 1,4 >[/tex]

So, it is obtained that -

[tex]a\vec{v}+b\vec{u}=\vec{w}[/tex]

Substitute all the values in the equation -

a<-1,2> + b<1,1> = <1,4>

<-a,2a> + <b,b> = <1,4>

<-a+b,2a+b> = <1,4>

The two equation obtained are -

-a + b = 1

2a + b = 4

Subtracting the equation 1 from 2 -

2a + b - (-a + b) = 4 - 1

2a + b + a - b = 3

3a = 3

a = 1

Substitute the value of a in equation 1 -

-1 + b = 1

b = 1 + 1

b = 2

So, the equation [tex]a\vec{v}+b\vec{u}=\vec{w}[/tex] becomes -

[tex]\vec{v} + 2\vec{u} = \vec{w}[/tex]

Therefore, the vector is obtained as [tex]\vec{w} = 2\vec{u} + \vec{v}[/tex].

Step-by-step explanation:

The probability that the last red ball was the 8th ball out is 3/10

Number of red  balls = 3 red balls

Number of black balls = 7 black balls

Then you randomly draw the balls out one by one without replacement.

The probability is the ratio of the number of favorable outcomes to the total number of outcomes

The equation will be

Probability = Number of favorable outcomes / Total number of outcomes

Total number of outcomes = 3 + 7

= 10

Substitute the values in the equation

The probability that the last red ball was the 8th ball out = 3/10

Let's call the radius of the circle "r". The formula for the area of a sector of a circle is given by:

(θ/360) * π * r^2,

where θ is the central angle of the sector in degrees.

In this case, we know that the central angle is 315° and the area of the sector is 504π, so we can set up an equation as follows:

(315/360) * π * r^2 = 504π

Solving for r, we can isolate it on one side of the equation:

r^2 = 504 / (π * (315/360))

To simplify the expression on the right-hand side, we can divide both the numerator and denominator by 45 (which is a factor of both 315 and 360):

r^2 = 504 / (π * (7/8))

Finally, taking the square root of both sides gives us:

r = sqrt(504 / (π * (7/8)))

So the radius of the circle is approximately 17.14 inches.

The two real distinct solutions for the quadratic equation are x = 3 and x = -3.

Which means x - 3 and x + 3 are the factors of the equation.

Hence;

So the answer is C. (x - 3)^2.

Step-by-step explanation:

The complete square corresponding to x^2 - 6x is (x - 3)^2.

A complete square is a trinomial that can be written in the form (x - a)^2, where a is a constant. To find the complete square of x^2 - 6x, we need to rewrite x^2 - 6x into the form (x - a)^2. We do this by adding and subtracting a constant term to make the trinomial a perfect square.

x^2 - 6x + 9 = (x - 3)^2

So the answer is C. (x - 3)^2.

Answer:

(24) + (20) + (8) = 52 ft^2

Step-by-step explanation:

This figure is a compound of 3 rectangles that can be split up like in my attached picture.

The top, horizontal rectangle is 8x3 = 24 sq ft.

The bottom, almost square rectangle is 4x5 = 20 sq ft.

The middle rectangle has a height of 4 feet and a width of (8-6) = 2 feet.

So, its area is 4x2= 8 sq ft.

The compound figure is the sum of all of these areas:

24 + 20 + 8 = 52

The area of the compound figure is 52 sq ft.

Area of 1 = 8 * 3 = 24

Area of 2 = 4 * 2 = 8

Area of 3 = 5 * 4 = 20

Total area = 24 + 8 + 20 = 52

The first term of an arithmetic progression is 5 and the 10th term is 95. The sum of the first 10 terms is 455.

The sum of the first 10 terms of an arithmetic progression (A.P.) can be found using the formula:

S_n = n/2 * (2a + (n-1)d)

where a is the first term, d is the common difference, and n is the number of terms.

Given that the first term is 5 and the 10th term is 95, we can find the common difference (d) using the formula:

a_n = a + (n-1)d

Plugging in n = 10 and a = 5, we get:

95 = 5 + (10 - 1)d

Solving for d, we get:

d = (95 - 5) / (10 - 1) = 9

Now that we know the common difference, we can find the sum of the first 10 terms:

S_10 = 10/2 * (2 * 5 + (10 - 1) * 9) = 10/2 * (10 + 81) = 10/2 * 91 = 455

So, the sum of the first 10 terms is 455.
