A fraction represented with its quotient and remainder is a mixed fraction. For example, 2 1/3 is a mixed fraction, where 2 is the quotient, and 1 is the remainder. So, a mixed fraction is a combination of a whole number and a proper fraction.

Given here : Two mixed fractions as 5⁵/₂₉ and 3¹²/₁₃

But 5⁵/₂₉=150/29 and 3¹²/₁₃=51/13

Answer:

-4+4i and -4-4i

Step-by-step explanation:

To start off, we can distribute the x into the x+8 to get x^2 + 8x = -20. From here we can create a polynomial by moving the -20 to the other side by adding 20 to both sides to get x^2 + 8x +20 =0. From here we can check if there is any real solutions by finding the discriminant (the sqrt part of the quadratic formula) so 8^2-4(1)(20). 16-80. Because this gets us a negative number in an actual square root, there answers we would get would be imaginary.

However to solve what the roots are, we would plug the entire equation into the quadratic equation. Getting -8+- sqrt(-64)/2 which simplified is -4+-4i. Therefore our two answers are -4+4i and -4-4i

Angle BAC is equal to 72 degrees, which is calculated by subtracting 2 times the angle of intersection between lines p and q (34 degrees) from 180 degrees.

Given that two lines p and q intersect at X at an angle of 34 degrees

Let A be a point inside the 34 degree angle formed by p and q

Then, let B be the reflection of A through line p, and let C be the reflection of A through line q

To find angle BAC,

we must first understand that a reflection of a point across a line results in an angle equal in measure to its original angle, but on opposite sides of the line of reflection.

In this case, because A is inside the 34 degree angle formed by lines p and q,

angle AXB must be equal to 34 degrees

angle AXC must also be equal to 34 degrees

Therefore, angle BAC must be equal to 180 degrees minus 2 times 34 degrees, or 72 degrees.

In conclusion, the angle BAC is equal to 72 degrees.

Step-by-step explanation:

The total area from given figure is 53.13 square units.

Area is the amount of space occupied by a two-dimensional figure. In other words, it is the quantity that measures the number of unit squares that cover the surface of a closed figure. The standard unit of area is square units which is generally represented as square inches, square feet, etc.

From the graph, we can see three shapes rectangle with length= 6 units and width= 5 units, triangle with height = 6 units and base = 3 units and semicircle with diameter = 6 units

Here, area of a rectangle is Length×Width

= 6×5

= 30 square units

Area of a triangle = 1/2 ×Base×Height

= 1/2 ×3×6

= 9 square units

Area of a semicircle = πr²/2

= 3.14×3²/2

= 3.14×4.5

= 14.13 square units

Total area = 30+9+14.13

= 53.13 square units

Answer:

Step-by-step explanation:

Buying price

$80×6= $480

Selling price

$25×4×6= $600

Profit

$600-$480=$120

The profit on six dozen calculators is $120.

To calculate the profit on six dozen calculators, we need to find the cost of purchasing six dozen calculators and the revenue from selling six dozen calculators.

Since each dozen costs $80, the cost of purchasing six dozen calculators is:
$80 x 6 = $480

Since three calculators are sold for $25, the revenue from selling six dozen calculators is:
$25 x (6 x 12/3) = $25 x 24 = $600

The profit is the revenue minus the cost:
$600 - $480 = $120

The profit on six dozen calculators is $120.

The correct question is-

The mean and standard deviation of the sample data collected on continuous variable x are −0.25 and 0.03, respectively. The following table shows the relative frequencies of the data in the given intervals.

Based on the table, do the data support the use of a normal model to approximate population characteristics?

Answer: 39.805

Step-by-step explanation: 39.81 - 39.8 = 0.01

0.01 x 0.5 = 0.005

39.8 + 0.005 = 39.805

The 95% confidence interval for the population mean is approximately (1,218, 1,271)

A 95% confidence interval for the population mean can be calculated as follows:

Calculate the standard error (SE) of the mean: SE = standard deviation/sqrt (sample size) = 38 / sqrt(16) = 12.56

Use the t-distribution to find the critical value, t*, for a 95% confidence level and degrees of freedom (df) = sample size - 1 = 15.

Calculate the margin of error (ME) as ME = t* * SE = t* * 12.56.

Calculate the lower bound and upper bound of the confidence interval: lower bound = sample mean - ME = 1,245 - ME; upper bound = sample mean + ME = 1,245 + ME.

Since the degrees of freedom for this sample size is quite small, the critical value for t-distribution can be approximated using a t-table for a 95% confidence level and df = 15. The critical value is approximately 2.131.

So, the margin of error is ME = 2.131 * 12.56 = 26.86, and the 95% confidence interval for the population mean is:

Lower bound: 1,245 - 26.86 = 1,218 (rounded to the nearest whole number)

Upper bound: 1,245 + 26.86 = 1,271 (rounded to the nearest whole number)

Therefore, the 95% confidence interval for the population mean is approximately (1,218, 1,271).
