Answer:

Step-by-step explanation:

y = 5x + 2.....so we will sub in 5x + 2 for y, back into the other equation

3x = -y + 10

3x = - (5x + 2) + 10

3x = -5x - 2 + 10

3x + 5x = 8

8x = 8

x = 8/8

x = 1

y = 5x + 2

y = 5(1) + 2

y = 5 + 2

y = 7

check it... (1,7)

3x = -y + 10                           y = 5x + 2

3(1) = -7 + 10                          7 = 5(1) + 2

3 = 3 (correct)                       7 = 7 (correct)

so ur solution is : x = 1 and y = 7...or (1,7) <=====

Answer:

(1,7)

Step-by-step explanation:

Since we know that y=5x+2, we replace y in the bottom equation with 5x+2.

3x=-(5x+2)+10

Then distribute the - into both of the parentheses (multiply both terms by -1):

3x=-5x-2+10

Then add like terms:

3x=-5x+8

Add 5x to both sides:

8x=8

Divide both sides by 8:

x=1

Plug the known x value into y=5x+2:

y=5(1)+2

Multiply:

y=5+2

Final answer:

To find the probability of having 2, 3, or 4 successes in five trials where the probability of success is 40%, we calculate each scenario's probability using the binomial probability formula and sum them. The total probability is 65.3%, rounded to the nearest tenth of a percent.

Explanation:

To calculate the probability of having 2, 3, or 4 successes in five trials of a binomial experiment where the probability of success is 40%, we use the binomial probability formula:

P(X = k) = C(n, k) * p^k * (1-p)^(n-k)

Where:

P(X = k) is the probability of k successes in n trials

C(n, k) is the combination of n trials taken k at a time

p is the probability of success on an individual trial

(1-p) is the probability of failure on an individual trial

Let's calculate each probability:

P(X = 2) = C(5, 2) * 0.4² * 0.6³

P(X = 3) = C(5, 3) * 0.4³ * 0.6²

P(X = 4) = C(5, 4) * 0.4⁴ * 0.6¹

To find the total probability of having either 2, 3, or 4 successes (P(X = 2 or 3 or 4)), we add up these probabilities:

P(X = 2 or 3 or 4) = P(X = 2) + P(X = 3) + P(X = 4)

Let's use the combination formula to calculate these probabilities:

P(X = 2) = 10 * 0.4² * 0.6³ = 0.2304

P(X = 3) = 10 * 0.4³ * 0.6² = 0.3456

P(X = 4) = 5 * 0.4⁴ * 0.6 = 0.0768

Therefore:

P(X = 2 or 3 or 4) = 0.2304 + 0.3456 + 0.0768 = 0.6528 or 65.3% (rounded to the nearest tenth of a percent)

Answer:

(351.04, 368.96)

Step-by-step explanation:

Given that population mean= 360

Std devitaion = 4

margin of error = 2.5%= 0.025

Since population std deviation is known we can use Z critical value

For two tailed critical value for 2.5% would be

2.24

Margin of error = ±Critical value*std deviation

= ±2.24(4)

= ±8.96

Confidence interval =(Mean - margin of error, mean + margin of error)

Step-by-step explanation:

The value obtained by using the remainder theorem for the the  f(x)=2x5−3x4−9x3+8x2+2 at x=−3 will be 2x⁴-9x³+18x²-46x+138-(412)/(x+3).

It is defined as a special type of relationship, and they have a predefined domain and range according to the function every value in the domain is related to exactly one value in the range.

It is given that,use the Remainder Theorem to evaluate f(x)=2x5−3x4−9x3+8x2+2 at x=−3

A method for Euclidean polynomial division is the remainder theorem. This theorem states that if we divide a polynomial, P(x), by a factor, (x - a), which isn't really an element of the polynomial, we get a smaller polynomial and a remainder.

[tex]=\frac{2x^5-3x^4-9x^3+8x^2+2}{\left(x+3\right)} \\\\ =2x^4+\frac{-9x^4-9x^3+8x^2+2}{x+3} \\\\ =2x^4-9x^3+18x^2+\frac{-46x^2+2}{x+3}\\\\ =2x^4-9x^3+18x^2-46x+\frac{138x+2}{x+3} \\\\ =2x^4-9x^3+18x^2-46x+138+\frac{-412}{x+3} \\\\ =2x^4-9x^3+18x^2-46x+138-\frac{412}{x+3}[/tex]

Answer:

  3 cm

Step-by-step explanation:

The formula for the area of a rectangle is ...

  A = LW . . . . . . area is the product of length and width

Fill in the given values and solve for the width (W).

  18 cm² = (6 cm)W

  (18 cm²)/(6 cm) = W = (18/6) cm²/cm . . . . . . divide by the coefficient of W

  W = 3 cm

The width of the rectangle is 3 cm.

The width of a rectangle, with a length of 6 cm and an area of 18 cm squared, is 3 cm.

The question is asking for the width of a rectangle which we can find using the formula for the area of a rectangle. The formula is: Area = Length x Width. From the given question, we know that the area is 18 cm2 and the length is 6 cm. So, we can set up the equation: 18 = 6 x Width. To solve for width, we divide both sides of the equation by 6. This gives us Width = 18 ÷ 6 which equals 3 cm.

Answer:

Solid / plane

Step-by-step explanation:

A cross-section is a geometric concept, representing the intersection of a solid and a plane. The shape of the cross-section depends on how the plane intersects with the solid. A related physics concept is the continuity equation which states that the amount of incompressible liquid entering a cross-sectional area must equal the amount leaving it.

In mathematical terms, a cross-section is usually the intersection of a 3-dimensional solid with a plane. This concept is often used in Geometry. For instance, if we intersect a cylinder with a plane perpendicular to the base of the cylinder, the cross-section will be a circle which is the same size as the base of the cylinder. On the other hand, if the plane is parallel to the axis of the cylinder, the cross-section would be a rectangle.

A related concept, from the field of Physics, as described in Figure 14.28, is the continuity equation, usually applied when analyzing fluid dynamics. The equation posits that the volume of fluid entering a cross-sectional area of a duct or pipe must equal the volume of fluid leaving it, assuming the fluid is incompressible. This is because the mass of liquid cannot change within a closed system.

Answer:

x=7 is the answer

3x+6=27 is the equation

x=7 is the correct answer for the equation.

To solve the equation 3x + 6 = 27, subtract 6 from both sides and then divide by 3 to get x = 7. Verify by substituting x = 7 back into the original equation. This confirms the solution is correct by making a true statement.

Step by Step Solution:

When solving an algebraic equation, the goal is to find the value of the variable that makes the equation true. For example, consider the equation 3x + 6 = 27. To solve for x, follow these steps:

Subtract 6 from both sides of the equation: 3x + 6 - 6 = 27 - 6, which simplifies to 3x = 21.

Next, divide both sides by 3: 3x / 3 = 21 / 3, which gives x = 7.

To verify the solution, substitute x = 7 back into the original equation: 3(7) + 6 = 27. Simplifying this, we get 21 + 6 = 27, which is a true statement, verifying our solution.

Note that an identity in algebra is an equation that is true for all values of the variable, such as 6 = 6. In our example, the solution x = 7 makes both sides of the original equation equal, thus satisfying the equation.

Answer:

Dimension= [tex](4\times 7)\ feet[/tex]

Step-by-step explanation:

Given: Area of Carport= 28 feet²

           The height of the carport is 1 feet less than 2 times its length.

Lets assume the length of Carport be "w"

∴ Height of carport= [tex](2w-1)\ feet[/tex]

We know, Area of rectangle= [tex]width\times length[/tex]

∴[tex]28= w\times (2w-1)[/tex]

Using distributive property of multiplication.

⇒ [tex]28= 2w^{2} -w[/tex]

Subtracting both side by 28.

⇒ [tex]2w^{2} -w-28= 0[/tex]

Using the quadratic formula to solve the equation.

⇒ [tex]2w^{2} -w-28= 0[/tex]. what are the values of w.

Solving by using quadratic formula.

Formula: [tex]\frac{-b\pm \sqrt{b^{2}-4(ac) } }{2a}[/tex]

∴ In the equation [tex]2w^{2} -w-28= 0[/tex] , we have a= 2, b= -1 and c= -28.

Now, subtituting the value in the formula.

= [tex]\frac{-(-1)\pm \sqrt{(-1)^{2}-4(2\times -28) } }{2\times 2}[/tex]

= [tex]\frac{1\pm \sqrt{1 - 4(-56) } }{4}[/tex]

Opening parenthesis.

= [tex]\frac{1\pm \sqrt{1+224 } }{4}[/tex]

= [tex]\frac{1\pm \sqrt{225}}{4}[/tex]

We know 15²=225

= [tex]\frac{1\pm \sqrt{15^{2}}}{4}[/tex]

we know √a²=a

= [tex]\frac{1\pm 15 }{4}[/tex]

Now we have two solution

= [tex]\frac{16}{4} \ or\ \frac{-14}{4}[/tex]

Ignoring negative base or width or carport

∴ w= [tex]\frac{16}{4} = 4[/tex]

Hence, Length of carport is 4 feet

next subtituting the value of length to get height of carport

Height of carport= [tex](2w-1)\ feet[/tex]

⇒ Height of carport= [tex](2\times 4-1)[/tex]

⇒ Height of carport= [tex]7\ feet[/tex]

Hence dimension of rectangular carport= [tex](4\times 7)\ feet[/tex]

Final answer:

The correct system of linear inequalities that models Kim's work situation is option B, which includes the inequalities x + y ≤ 15 and 5x + 7y ≥ 65. These inequalities account for the maximum hours she can work and the minimum income she wants to earn. The correct option is B.

Explanation:

The student is asking for the system of linear inequalities that models Kim's work situation based on the hours she can work at two different jobs with different hourly rates. To model this situation, we have two variables: x for the number of hours worked at the first job and y for the hours at the second job. The first inequality comes from the maximum hours she can work, which is 15. Therefore, the combined hours worked at both jobs cannot exceed 15, which gives us:

x + y ≤ 15

The second inequality is derived from Kim's target earnings, which is at least $65. So, the income from both jobs combined must be at least $65, which gives us:

5x + 7y ≥ 65

Taking into account the given options, the correct system of linear inequalities is represented by option B:

x + y ≤ 15

5x + 7y ≥ 65
