To solve for x in the equation:

11.6% = x × 17.8% + (1 - x) × 8.4%

We can first convert the percentages to decimal form:

11.6% = 0.116

17.8% = 0.178

8.4% = 0.084

Substituting these values into the equation, we get:

0.116 = x  0.178 + (1 - x) × 0.084

Next, we can simplify the equation by distributing the (1 - x) term:

0.116 = x × 0.178 + 0.084 - x × 0.084

Simplifying further by combining like terms, we get:

0.116 = 0.178x + 0.084 - 0.084x

0.116 = 0.094x + 0.084

Subtracting 0.084 from both sides of the equation, we get:

0.032 = 0.094x

Finally, dividing both sides of the equation by 0.094, we get:

x = 0.3404 or approximately 0.34

Therefore, x is approximately 0.34

The surface formed by the equation 25x²+4y²+z²=100 is an ellipse.

In mathematics, an ellipse is a planar curve with two focus points, where the total of the two distances from any point on the curve to the focal points is a constant. It generalises the shape of a circle, a unique variety of ellipse in which the two focus points coincide. The eccentricity of an ellipse is used to calculate its length.

We may set one of the variables at a constant value and then plot the resulting 2D curve in the plane created by the other two variables in order to sketch the surface. This procedure can be repeated for various constant values to get a rough surface drawing.

Answer:

She read 4/5 of a book per month

Step-by-step explanation:

4/5= 4/5per month

Step-by-step explanation:

To find out how many books Tanisha read each month, we can use the formula:

books read per month = total number of books ÷ total number of months

Using the information given in the problem, we know that Tanisha read 4 books in 5 months. So we can plug those values into the formula:

books read per month = 4 ÷ 5

Simplifying the fraction by dividing the numerator and denominator by their greatest common factor, which is 1, we get:

books read per month = 4/5

Therefore, Tanisha read 4/5 of a book per month, or equivalently, 0.8 books per month.

Answer:

Karen got $8.00 per hour for babysitting. Find x, the amount she was paid for 8 hours of babysitting.

Step-by-step explanation:

the width of the garden is approximately 6.77 feet, and the length is approximately 11.77 feet (since it is 5 feet more than the width).

what is rectangle?

A rectangle is a four-sided polygon with opposite sides that are parallel and equal in length.

Let's denote the width of the garden by x. Then, according to the problem statement, the length of the garden is x + 5.

The total width of the garden and the walkway is x + 2(3) = x + 6, and the total length is x + 5 + 2(3) = x + 11.

The area of the garden itself is x(x + 5), and the area of the garden and the walkway is (x + 6)(x + 11).

The area of the walkway is the difference between the two: (x + 6)(x + 11) - x(x + 5) = 210.

Expanding and simplifying this expression, we get:

x^2 + 17x - 135 = 0

We can solve for x using the quadratic formula:

x = (-b ± sqrt(b^2 - 4ac)) / 2a

In this case, a = 1, b = 17, and c = -135, so we have:

x = (-17 ± sqrt(17^2 - 4(1)(-135))) / 2(1)

x = (-17 ± sqrt(769)) / 2

We can discard the negative solution, so we have:

x = (-17 + sqrt(769)) / 2

x ≈ 6.77

Therefore, the width of the garden is approximately 6.77 feet, and the length is approximately 11.77 feet (since it is 5 feet more than the width).

Answer:

To find the mean of a set of data, we need to sum up all the values in the set and divide by the number of values.

Sum of the data values = 19 + 23 + 35 + 41 + 42 = 160

Number of data values = 5

Mean = Sum of data values / Number of data values = 160 / 5 = 32

However, we are given that the mean is 36. Since the calculated mean is lower than the given mean, it means that we are missing a value that is higher than the other values in the set.

Let's call this missing value x. Then, we have:

(19 + 23 + 35 + 41 + 42 + x) / 6 = 36

Multiplying both sides by 6, we get:

19 + 23 + 35 + 41 + 42 + x = 216

Simplifying the left-hand side, we get:

160 + x = 216

Subtracting 160 from both sides, we get:

x = 56

Therefore, the missing value is 56, and the complete data set is:

19, 23, 35, 41, 42, 56

Now, we can calculate the mean as:

Mean = (19 + 23 + 35 + 41 + 42 + 56) / 6 = 216 / 6 = 36

So, the mean of the data values is indeed 36.

Answer:

32

Step-by-step explanation:

To find the mean of a set of numbers, we add up all the numbers and then divide by the total number of values.

Adding up the values:

19 + 23 + 35 + 41 + 42 = 160

We have a total of 5 values, so we divide the sum by 5:

160 / 5 = 32

Therefore, the mean of the given data values is 32, not 36.

14[tex]\frac{1}{2}[/tex] x 6[tex]\frac{1}{2}[/tex] x 6[tex]\frac{1}{2}[/tex]

Step-by-step explanation:

The variability of the mean is 0.154

The total of all values divided by all of the values constitutes the result of a set, also called as the arithmetic mean. It is considered to be the most popular central trend indicator, and the word "mean" is commonly used to describe it. The average of a figure is known to as the average.

We are Given a normal distribution, the MAD and standard deviation (SD) are roughly inversely proportional to one another as follows:

=> MAD = 1.4826 × SD

Here we can calculate the standard deviation as follows:

=> SD = MAD / 1.4826

Since the MAD in this instance is provided as 3.2,

=> SD ≈ 3.2 / 1.4826 ≈ 2.16

The standard error of the mean (SEM), can be determined as follows, then gives the variability of the mean.

=> SEM ≈ SD / sqrt(n)

=> CV Equals SD/mean

The probability that a randomly selected driver in the 20-24 age bracket will be in a car crash during the next year is 0.86%.

It is unlikely for a driver in that age bracket to be involved in a car crash during a year

The resulting probability of 0.0086 is relatively low.

The approximate probability can be calculated by dividing the number of drivers who were in a car crash in the last year by the total number of drivers in the 20-24 age bracket:

Probability = Number of drivers in a car crash / Total number of drivers in the age bracket

Probability = 3/350

Probability ≈ 0.0086

The equation which represents a proportional relationship from the given set of equations is y = 4x.

What is meant by a proportional relationship?

Relationships between two variables that are proportional occur when their ratios are equal. Another way to consider them is that in a proportional relationship, one variable is consistently equal to the other's constant value. y= k x, where k is the proportionality constant, is the equation that depicts a directly proportional relationship, or a line. y = k(1/x) or xy = k, where k is the proportionality constant, is the equation that depicts an indirectly proportional relationship, or a line. One can argue that two variables are in a proportional relationship if one variable is always equal to a constant multiplied by the other variable.

So according to the above explanation, we can say that the equation y = 4x is an example of a proportional relationship.

This is because the ratio y/x is always a constant 4.

Therefore the equation which represents a proportional relationship is y = 4x.

The general form of the equation for the given circle centered at O(0, 0) is B. x² + y² - 41 = 0.

A circle is a round, two-dimensional shape with all points on its boundary equidistant from its center.

Since the center of the circle is O(0,0), the equation of the circle will have the form x² + y² + ax + by + c = 0. To find the values of a, b, and c, we can use the fact that point B(4, 5) lies on the circle. Substituting the coordinates of B into the equation and simplifying, we get:

4² + 5² + a4 + b5 + c = 0

16 + 25 + 4a + 5b + c = 0

41 + 4a + 5b + c = 0

We now have one equation with three variables, so we need more information. Since the center of the circle is (0,0), we know that the distance from the center to any point on the circumference is equal to the radius of the circle. The distance between points (0,0) and (4,5) is the length of the line segment joining them, which can be found using the distance formula:

[tex]\sqrt{(4-0)\² + (5-0)\²} = \sqrt{(16+25) }= \sqrt{41}[/tex]

Therefore, the radius of the circle is √(41). We can use this fact to eliminate one of the variables in the equation we derived earlier. Since point (0,0) lies on the circle, we can substitute its coordinates into the equation to get:

41 + 0a + 0b + c = 0

c = -41

Now we can substitute this value of c back into the equation we derived earlier to get:

41 + 4a + 5b - 41 = 0

4a + 5b = 0

Finally, we have two equations with two variables, which we can solve to get:

a = -5/4

b = 4/5

Substituting these values into the equation of the circle, we get:

x² + y² - 5x/4 + 4y/5 - 41 = 0

Multiplying by 20 to eliminate fractions, we get:

20x² + 20y² - 25x + 16y - 820 = 0

Simplifying, we get:

x² + y² - 25/4x + 4/5y - 41 = 0

Which is equivalent to:

x² + y² - 41 = 0
