The probability that the sample mean will fall within $600 of the population of average family income mean is 0.3203 or 32.03%.

Population standard deviation = σ = $4800

Sample size = n = 225

Difference between the sample mean and population mean = d = $600

We need to find the probability that the sample mean will fall within $600 of the population mean.

We can use the z-score formula for sample means to find this probability:

z = (x - μ) / (σ / √n)

where z is the z-score, x is the sample mean, μ is the population mean, σ is the population standard deviation, and n is the sample size.

Substituting the given values, we get:

z = ($600) / ($4800 / √225)

z = 0.75

Using the standard normal distribution table or calculator, we can find the probability that z is between -0.75 and 0.75:

P(-0.75 < z < 0.75) = 0.5469 - 0.2266 = 0.3203

Therefore, the probability that the sample mean will fall within $600 of the population of average family income mean is 0.3203 or 32.03%.

To obtain the remaining funds necessary to purchase the skateboard, Seth must labor for 13 hours at a rate of $7.25 per hour.

To find out how many hours Seth needs to work to earn the remaining money, we need to first calculate how much money he still needs to earn:

Money needed = Cost of skateboard - Money in the bank

Money needed = $167 - $72.75

Money needed = $94.25

Now we can use Seth's hourly rate to figure out how many hours he needs to work to earn the remaining money:

Hours needed to work = Money needed / Hourly rate

Hours needed to work = $94.25 / $7.25 per hour

Hours needed to work = 13 hours (rounded up to the nearest hour)

Therefore, Seth needs to work for 13 hours at $7.25 per hour to earn the remaining money needed to buy the skateboard.

The mathematical equations of each problem is 24 = 2x - 2, y + 16 = 85, 56 = (1/2)x - 6, x = 1/3 * 12600 and 120 + 50x = 270 and their solution are Sister is 13 years old, Arvin sold 69 cakes yesterday, You have 124 stamps, Chiz earned P4,200 this month and The horse ride lasted for 60 minutes, with 30 minutes being the initial ride and 30 minutes for the additional ride, respectively.

The translation of each problem into a mathematical equation then solution is.

Let x be the age of the sister.

Then, we have the equation:

24 = 2x - 2

Adding 2 to both sides gives:

26 = 2x

Dividing both sides by 2 gives:

x = 13

Therefore, the sister is 13 years old.

Let y be the number of cakes Arvin sold yesterday.

Then, we have the equation:

y + 16 = 85

Subtracting 16 from both sides gives:

y = 69

Therefore, Arvin sold 69 cakes yesterday.

Let x be the number of stamps you have.

Then, we have the equation:

56 = (1/2)x - 6

Adding 6 to both sides gives:

62 = (1/2)x

Multiplying both sides by 2 gives:

x = 124

Therefore, you have 124 stamps.

Let x be the amount Chiz earned this month.

Then, we have the equation:

x = 1/3 * 12600

Simplifying gives:

x = 4200

Therefore, Chiz earned P4,200 this month.

Let x be the number of 10-minute blocks for the additional horse ride time.

Then, we have the equation:

120 + 50x = 270

Subtracting 120 from both sides gives:

50x = 150

Dividing both sides by 50 gives:

x = 3

Therefore, the additional horse ride time was 3 blocks of 10 minutes, or 30 minutes in total. Adding this to the initial 30 minutes gives a total ride time of 60 minutes.

Answer:

[tex]\left(\begin{array}{cc}0&24\\13&27\end{array}\right)[/tex]

Step-by-step explanation:

I will attempt to explain using the following example. Let us consider the  product (multiplication) of the following matrices:

[tex]\left(\begin{array}{cc}a_{1,1}&a_{1,2}\\a_{2,1}&a_{2,2}\end{array}\right) \cdot \left(\begin{array}{cc}b_{1,1}&b_{1,2}\\b_{2,1}&b_{2,2}\end{array}\right) = \left(\begin{array}{cc}c_{1,1}=c_{1\times 1}&c_{1,2}=c_{1\times2}\\c_{2,1}=c_{2\times1}&c_{1,2}=c_{2\times2}\end{array}\right)[/tex]

Note that the first number in each coefficient refers to the row number, while the second number refers to the column number.

Then [tex]a_{2,1}[/tex] indicates the element in the second row and first column.

To calculate the product of two matrices, we need to multiply each row of the first matrix by each column of the second matrix.

Example:

[tex]c_{1,1}= (a_{1,1} \cdot b_{1,1} + a_{1,2} \cdot b_{2,1})[/tex]

Now, we can apply this to the original exercise:

[tex]\left(\begin{array}{cc}5&-2\\4&1\end{array}\right) \left(\begin{array}{cc}2&6\\5&3\end{array}\right) =\left(\begin{array}{cc}c_{1,1}&c_{1,2}\\c_{2,1}&c_{2,2}\end{array}\right)[/tex]

Next, we will calculate each value of c using the multiplication process we just discussed.

[tex]c_{1,1}= (5(2)+-2(5)) = 10-10 =0\\c_{1,2}= (5(6)+-2(3)) = 30-6 =24\\c_{2,1}= (4(2)+1(5)) = 8+5 =13\\c_{2,2}= (4(6)+1(3)) = 24+3 =27\\[/tex]

Thus, we have obtained the final result of the matrix product:

[tex]\left(\begin{array}{cc}5&-2\\4&1\end{array}\right) \left(\begin{array}{cc}2&6\\5&3\end{array}\right) =\left(\begin{array}{cc}0&24\\13&27\end{array}\right)[/tex]

Answer:

  132 in

Step-by-step explanation:

You want to know the perimeter of a triangle after the dimensions are quadrupled.

"Quadrupled" means "multiplied by 4."

The perimeter is the sum of the lengths of the sides of the triangle:

  P = 8 +10 +15 = 33 . . . . inches

If the sides are quadrupled, it is ...

  P' = 4(8) +4(10) +4(15) = 4(8 +10 +15) = 4(33) = 132 . . . . inches

As you can see, if the sides are quadrupled, the perimeter is quadrupled.

The new perimeter is 132 inches.

Multiplying 13 m by itself and multiplying the result by π gives us the area of the sidewalk as A = 530.94 m². We can calculate the area of the sidewalk with A = πr²

The area of the circular sidewalk around the flower bed can be calculated using the formula for the area of a circle: A = πr². To find the radius of the sidewalk, we need to subtract the radius of the flower bed from the diameter of the flower bed and the sidewalk. Therefore, the radius of the circular sidewalk is (19 m - 3 m - 3 m) = 13 m.Using the formula for the area of a circle, we can calculate the area of the sidewalk with A = πr², where r = 13 m.

We can use algebra to determine how many years it has been since the cost of a box of pencils was $0.00, and therefore calculate how many years the price has been increasing by $1.10 per year.

Let's say that x is the number of years since the cost of a box of pencils was $0.00.

If the price of a box of pencils is increasing by $1.10 per year, then the cost of a box of pencils x years after it cost $0.00 would be:

$0.00 + ($1.10 * x)

We know that the current cost of a box of pencils is $2.19. Setting this equal to the expression above, we can solve for x:

$0.00 + ($1.10 * x) = $2.19

$1.10 * x = $2.19

x = $2.19 / $1.10

x = 1.99

So, it has been approximately 1.99 years (or just under 2 years) since the cost of a box of pencils was $0.00, and the price of a box of pencils has been steadily increasing by $1.10 per year during that time.

The probability of having an error when confidence limits are 3 standard deviations far from the mean is approximately 0.27.

Assume that the data is normally distributed. For a normal distribution, approximately 99.7% of the data is within 3 standard deviations of the mean.

As a result, if the lower and upper specification limits are 3 standard deviations away from the mean, they encompass 99.7% of the data.

As a result, there is only a 0.3% chance of an error. Since this is a two-tailed test, the probability of an error on each side is 0.15%

As a result, the probability of an error when the lower and upper specification limits are 3 standard deviations away from the mean is approximately 0.27.

Answer:

(16x^2 + 46x + 20)/(4x + 5) ft

Step-by-step explanation:

he area of the yard is given by (8x^2+13x+5) ft^2. The length of the yard is (8x+5) ft. The width of the yard is (8x^2+13x+5)/(8x+5) ft.

The fence is along the length and two widths of the yard. Therefore, the length of the fence is 2(8x+5) ft and the width of the fence is 2(8x^2+13x+5)/(8x+5) ft.

The total length of the fence is the sum of the length and width of the fence.

Therefore, the total length of the fence is 2(8x+5) + 2(8x^2+13x+5)/(8x+5) ft.

Simplifying the expression, we get:

2(8x+5) + 2(8x^2+13x+5)/(8x+5) = (16x^2 + 46x + 20)/(4x + 5) ft.

Therefore, Karla’s dad will need (16x^2 + 46x + 20)/(4x + 5) ft of fencing.

The y-intercept is 5.5 inches, which is the initial height of the plant before it started growing.

We can use the slope-intercept form of a linear equation, y = mx + b, where m is the slope and b is the y-intercept, to solve the problem.

Since the plant is growing at a constant rate of 1.4 inches per day, the slope of the line that represents its growth is 1.4.

Let y be the height of the plant after x days. We know that the plant was 5.5 inches tall on day 0, so we have the point (0, 5.5) on the line.

Using the point-slope form of a linear equation, we get:

y - 5.5 = 1.4x

Simplifying, we get:

y = 1.4x + 5.5

Comparing the equation to the slope-intercept form, we see that the y-intercept is 5.5.

Therefore, the y-intercept is 5.5 inches.

if it is a vector

First, we need to multiply each vector component by its corresponding scalar value and then add them together.

a + 2b - c + 4d = (4)(1) + (4)(2) + (-3)(-1) + (5)(4) = 4 + 8 + 3 + 20 = 35

Therefore, the value of a + 2b - c + 4d is 35.

if it is a matrix

we can form a 1x4 matrix for vector a, b, c, and d respectively. We can also form a 4x4 matrix for the scalar values. Then we can perform matrix multiplication as follows:

(4 4 -3 5) (1 0 0 0) (0 2 0 0) (0 0 -1 0) (0 0 0 4)

= (41 + 40 - 30 + 50) (40 + 42 - 30 + 50) (40 + 40 - 3*(-1) + 50) (40 + 40 - 30 + 5*4)

Therefore, (x-2)^2 simplifies to x^2 - 4x + 4.

3- (3x+1)^2

Expanding using the formula for the square of a binomial, we get:

(3x+1)^2 = (3x)^2 + 2(3x)(1) + (1)^2

= 9x^2 + 6x + 1

Therefore, (3x+1)^2 simplifies to 9x^2 + 6x + 1.

4- (3x-1)(2x^2+5x-4)

Using the distributive property, we can multiply each term in the first polynomial by each term in the second polynomial:

(3x-1)(2x^2+5x-4) = 3x(2x^2) + 3x(5x) - 3x(4) - 1(2x^2) - 1(5x) + 1(4)

= 6x^3 + 15x^2 - 12x - 2x^2 - 5x + 4

= 6x^3 + 13x^2 - 17x + 4

Therefore, (3x-1)(2x^2+5x-4) simplifies to 6x^3 + 13x^2 - 17x + 4.

[tex](5x^8y^4)/(15x^3y^8) = (x^5/y^4) * (1/3)[/tex] is the fully simplified expression using only positive exponents.

To simplify [tex](5x^8y^4)/(15x^3y^8)[/tex], we can start by dividing the numerator and denominator by their greatest common factor, which is[tex]5x^3*y^4[/tex]:

[tex](5x^8y^4)/(15x^3y^8) = (x^8/x^3) * (y^4/y^8) * (1/3)[/tex]

Now we can simplify each term separately. First, [tex]x^8[/tex] divided by [tex]x^3[/tex] equals [tex]x^5[/tex], because when we divide two terms with the same base, we subtract their exponents:

[tex]x^8/x^3 = x^(8-3) = x^5[/tex]

Similarly, [tex]y^4[/tex]divided by[tex]y^8[/tex] equals [tex]1/y^4[/tex], because when we divide two terms with the same base, we subtract their exponents and change the sign:

[tex]y^4/y^8 = y^(4-8) = 1/y^4[/tex]

Finally, 1/3 is already in its simplest form. Putting it all together, we get:

[tex](5x^8y^4)/(15x^3y^8) = (x^5/y^4) * (1/3)[/tex]

This is the fully simplified expression using only positive exponents.

We can state that the original equation represents a fraction, where the numerator is the product of 15, the third power of x, and the eighth power of y, and the denominator is the product of 5, the eighth power of x, and the fourth power of y.

We then determined the numerator and denominator's largest common factor, which is 5x*3*y*4, in order to condense the formula. Using the exponentiation principles, we divided the numerator and denominator by this factor before simplifying each term. The end result is a fraction with x raised to the fifth power as the numerator, y raised to the fourth power as the denominator, and 3 as the common factor.

The perimeter of the shape is approximately 314.

The perimeter of a shape made from part of a circle can be found using the formula P = 2πr + 2s, where r is the radius of the circle and s is the length of the straight line segments. For example, if a shape is composed of a semicircle with radius 5 and two straight line segments of length 10, then the perimeter can be calculated as P = 2π(5) + 2(10) = 30π + 20 = 100π. To solve this calculation, we can use the value of π, which is approximately 3.14, to get the approximate perimeter of the shape as 100π ≈ 314.
