Answer:

Step-by-step explanation:

n! = 1 · 2 · 3 · 4 · ... · n

6! = 1 · 2 · 3 · 4 · 5 · 6 = 720

(4! × (6 - 4)!) = (1 · 2 · 3 · 4 × 2!) = 24 × 1 · 2 = 24 × 2 = 48

Answer:

A = choosing a red marble

B = choosing a green marble

Probability of A happening = P(A) = 5/(3+5+4) = 5/12

Probability of B happening = P(B) = 4/(3+5+4) = 4/12

Probability of either happening = P(A) + P(B) = 5/12 + 4/12 = 7/12

The key word in their question is red OR green and that is why we add the two probabilities. If they ask the probability of them both happening (if they said red AND green), you would multiply P(A)*P(B).

The probability that the chosen marble is not red is [tex]\frac{7}{12}[/tex].

A probability is a number that reflects the chance or likelihood that a particular event will occur.

The formula of the probability is

[tex]P(E) = \frac{Number\ of\ favorable\ outcomes}{Total\ number\ of\ outcomes }[/tex]

Where, P(E) is the probability of an event.

According to the given question.

Number of red marbles = 5

Number of blue marbles = 4

Number of green marbles = 3

So,

The total number of marbles in a bag = 5+4+3 = 12

And, the probability that chosen marble is red = [tex]\frac{5}{12}[/tex]

Therefore,

the probability that the chosen marble is not red

[tex]=1-\frac{5}{12} \\[/tex]

[tex]= \frac{12-5}{12}[/tex]

[tex]= \frac{7}{12}[/tex]

Hence, the probability that the chosen marble is not red is [tex]\frac{7}{12}[/tex].

Answer:

correct option for first blank is 5/4 and for second blank is [tex]\frac{ 3i\sqrt{7}}{4}[/tex]

i.e m= [tex]\frac{5}{4}\pm\frac{ 3i\sqrt{7}}{4}[/tex]

Step-by-step explanation:

The given equation

[tex]m^2 - \frac {5m}{2} = \frac{-11}{2}[/tex]

and we have to find m= ______ ± ________

We can use quadratic formula to solve this question.

The above equation can be written as: [tex]m^2 - \frac {5m}{2} + \frac{11}{2} = 0[/tex]

and the formula used will be:

[tex]m= \frac{-b\pm\sqrt{b^2-4ac}}{2a}[/tex]

Putting values of a= 1, b= -5/2 and c= 11/2 and solving we get:[tex]m=\frac{-\frac{-5}{2}\pm\sqrt{{(\frac{-5}{2})}^2-4(1)(\frac{11}{2})}}{2(1)}\\\\m=\frac{\frac{5}{2}\pm\sqrt{(\frac{25}{4})-22}}{2}\\m=\frac{\frac{5}{2}\pm\sqrt{(\frac{-63}{4})}}{2}\\m= \frac{\frac{5}{2}}{2}\pm\frac{\sqrt{(\frac{-63}{4})}}{2}\\m= \frac{5}{4}\pm\frac{\sqrt{-63}}{4}[/tex]

Since there is - sign inside the √ so [tex]\sqrt{-1}[/tex] is equal to i and we have to divide [tex]\sqrt{63}[/tex] into its multiples such that the square root of one multiple is whole no so,

[tex]\sqrt{63}[/tex]  = [tex]\sqrt{9}* \sqrt{7}[/tex]=[tex]3* \sqrt{7}[/tex]

Putting value of [tex]\sqrt{63}[/tex] and [tex]\sqrt{-1}[/tex]

the value of m= [tex]\frac{5}{4}\pm\frac{ 3i\sqrt{7}}{4}[/tex]

Answer:

multiply 22.8 by 22.8

Step-by-step explanation:

The y-coordinate of the midpoint of the vertical line segment is calculated by method B. Divide 15 by 2, which gives the midpoint's y-coordinate as 7.5.

To calculate the y-coordinate of the midpoint of a vertical line segment with endpoints at (0,0) and (0,15), you can use the method of dividing the y-coordinates of the endpoints by 2. In this case, you would divide 15 by 2 to find the midpoint's y-coordinate, which is method B. Divide 15 by 2. This is because the midpoint of a line segment is found by averaging the coordinates of the endpoints, and for the y-coordinates you add them together and then divide by 2. So, the calculation is (0 + 15) / 2, which equals 7.5. Thus, the midpoint of the segment is at the point (0, 7.5).

Step-by-step explanation:

Remember,  Gloria can knit one block in 50 minutes, and they want to know how many blocks she can knit in 5 whole hours.

Which means, that is 5 squares in 4 hours, but we still have the 10 minutes from each of the 50 minutes.

So, you add up the 5 ten minutes (50 minutes) Which gives you a whole square.

Therefore, Gloria can knit 6 squares in 50 minutes.

Gloria can knit 6 blocks in 5 hours if she maintains her knitting rate of one block every 50 minutes.

Gloria can knit one block of a quilt in 50 minutes. To find out how many blocks she can knit in 5 hours, one should first convert the knitting time from hours to minutes. Since there are 60 minutes in an hour, 5 hours is equal to 300 minutes. Next, divide the total available knitting time by the time it takes to knit one block.

300 minutes / 50 minutes per block = 6 blocks
So, if Gloria knits at the same rate, she can knit 6 blocks in 5 hours.

EXPLANATION

From the given information,the income is given by the function

[tex]f(x) = 2x + 54[/tex]

where f(x) is the income in dollars and x is the area in square meters of lawn mowed.

To find the area that corresponds to John's earnings, we equate the function to the earnings and solve for x.

For the area that corresponds to 204, we have

[tex]2x + 54 = 204[/tex]

[tex]2x = 204 - 54[/tex]

[tex]2x = 150[/tex]

[tex]x = 75[/tex]

For the area that corresponds to 344, we have:

[tex]2x + 54 = 344[/tex]

[tex]2x = 344 - 54[/tex]

[tex]2x=290[/tex]

[tex]x = 145[/tex]

For the area that corresponds to 450, we have

[tex]2x + 54 = 450[/tex]

[tex]2x= 450 - 54[/tex]

[tex]2x =396[/tex]

[tex]x = 198[/tex]

For the area that corresponds to 482, we have

[tex]2x + 54 = 482[/tex]

[tex]2x= 482 - 54[/tex]

[tex]2x = 428[/tex]

[tex]x = 214[/tex]

Therefore the correct answer is A.

Check the picture below.

make sure your calculator is in Degree mode.

Thus, the kite is height of 400 ft above the ground.

Hence, option B is correct.

A triangle is a three sided polygon, which has three vertices and three angles which has the sum 180 degrees.

Given that,

Hypotenuse of tringle = 520 ft

And inclination angle = 50.2 degree

We know that if any one of interior angle is of 90 degree then the angle is said to be right angle triangle.

Since,

sinΘ = (opposite side of Θ)/Hypotenuse

Therefore,

⇒ sin50.2 = Height/520         (since opposite side is height of triangle as shown in figure)

⇒ 0.76 = Height/520  

⇒ Height = 395.2 feet ≈ 400ft  (in nearest foot)

Hence,

Height of kite is 400 ft.

Answer:

D

Step-by-step explanation:

We can see in the graph f(x) that the x intercept is [tex](1,0)[/tex].

In the table of g(x), we can see that the x intercept is [tex](-1,0)[/tex].

Since [tex]1>-1[/tex], the x intercept of the graph f(x) is greater than the x intercept of graph g(x).

ANSWER

D. The x-intercept of f(x) is greater than the x-intercept of g(x).

EXPLANATION

From the graph, f(x) touches the y-axis at y=-1.

The y-intercept of -1

The graph touches the x-axis at x=1.

This is the x-intercept.

From the table, the y-intercept is the point with x-coordinate of zero.

From the table, x=0 when y=1.

The y-intercept of g(x) is 1.

The x-intercept is where y=0.

The x-intercept is -1.

The x-intercept of f(x), which is 1, is greater than the x-intercept of g(x), which is -1

Step-by-step explanation:

[tex]m+4\leq6[/tex]

We subtract 4 from each side to get [tex]m\leq2[/tex]

Let's plug in a random point such as 0.

[tex]0+4\leq6 \\ \\ 4\leq6[/tex]

Since this is true, the inequality we made is true.

For this case we must factor the following expression:

[tex]16x ^ 2-25y ^ 2[/tex]

By definition, the formula of square difference states that:

[tex]a ^ 2-b ^ 2 = (a + b) (a-b)[/tex]

In this case:

[tex]a = 4x\\b = 5y[/tex]

Then, we can factor the expression as:

[tex](4x + 5y) (4x-5y)[/tex]

Answer:

[tex](4x + 5y) (4x-5y)[/tex]

Final answer:

The expression [tex]16x^2-25y^2[/tex]is a difference of squares and factors into the product of two binomial conjugates, which is (4x + 5y)(4x - 5y).

Explanation:

The expression [tex]16x^2-25y^2[/tex] is a difference of squares, which is a special factoring case where you have two perfect squares separated by a subtraction sign. The difference of squares can be factored into the product of two binomials that are conjugates of each other. This means that they are identical except for the sign between their terms.

The factorization is:

Therefore, the factorization of the given expression is[tex]\((4x + 5y)(4x - 5y)\).[/tex]

The distance between the point (-3, -4) and the line 2y = -3x + 6 is 23 ÷ 13.

The distance between the point (-3, -4) and the line given by the equation 2y = -3x + 6 can be found using the point-to-line distance formula:

D = |Ax + By + C| ÷ (A^2 + B^2)

Firstly, we want to put the line equation in the standard form of Ax + By + C = 0. Let us rearrange the given equation of the line to this form:

3x + 2y - 6 = 0

Where A = 3, B = 2, and C = -6. Using the point (-3, -4), we plug the values into the point-to-line distance formula:

D = |3(-3) + 2(-4) - 6| ÷(3^2 + 2^2)

D = |-9 - 8 - 6| ÷(9 + 4)

D = | -23 | ÷ 13

D = 23 /÷ 13

Since ÷ 13 is an irrational number, we can't simplify it further. Therefore, the distance is:

D = 23 ÷ 13

Step-by-step explanation:

$40/4hr = $10/1hr =10

Answer:

See explanation

Step-by-step explanation:

Zeros of the function are those values of x, for which g(x)=0, so solve the equation g(x)=0:

[tex]x^3-x^2-4x+4=0\\ \\x^2(x-1)-4(x-1)=0\\ \\(x-1)(x^2-4)=0\\ \\(x-1)(x-2)(x+2)=0\\ \\x_1=-2,\ x_2=1,\ x_3=2[/tex]

Hence, the function has three zeros, x=-2, x=1 and x=2.

To find the y-intercept, substitute x=0:

[tex]y=g(0)=0^3-0^2-4\cdot 0+4=4,[/tex]

so y-intercept is at point (0,4).

The graph of the function shows that when x is infinitely small, then y is infinitely small too and if x is infinitely large, then y is infinitely large too.

Answer:

The zeros: x = 1, -2, 2

The y-intercept:  (0, 4)

The end behavior :

x  --> + ∞, f(x) --> + ∞

x  --> - ∞, f(x) --> - ∞

Step-by-step explanation:

Zero function:

x^3 - x^2 - 4x + 4 = 0

(x^3 - x^2) - (4x - 4) = 0

x^2(x - 1) - 4(x - 1) = 0

(x^2 - 4)(x - 1) = 0

(x + 2)(x - 2)(x - 1) = 0

x + 2 = 0; x = -2

x - 2 = 0; x = 2

x - 1 = 0; x = 1

The zeros: x = 1, -2, 2

The y-intercept when x = 0 so y-intercept = 4 or (0, 4)

The end behavior of a function f(x) :  the behavior of the graph of the function at the ends of the x-axis.

As x approaches + ∞, f(x) approaches + ∞

As x approaches - ∞, f(x) approaches - ∞
