From unit prices gotten, the price of one feet of annel fabric is cheaper than the price of one feet of fleece fabric.

A unit price is defined as the price for one item or measurement, such as a pound, a kilogram, or a pint. This can be used to compare the same type of goods sold in varying weights and amounts.

The parameters are;

3 yards of annel fabric costs $12.60

5 feet of fleece fabric costs $8.75.

From conversion units;

1 yard =  3 feet

Thus;

3 yards = 3 * 3 = 9 ft

Thus;

Unit price of Annel fabric = 12.6/9 = $1.4 per ft

Unit price of fleece fabric = 8.75/5 = $1.75 per ft

Step-by-step explanation:

[tex]\sqrt[3]{64xy^{3}}[/tex] = [tex]\sqrt[3]{64}[/tex] × [tex]\sqrt[3]{x}[/tex] × [tex]\sqrt[3]{y^{3}}[/tex]

a = coefficient

∴a = 4

[tex]x^{b}[/tex] = [tex]x^{-2}[/tex]×[tex]\sqrt[3]{x}[/tex]

   = [tex]x^{-2}[/tex]×[tex]x^{\frac{1}{3}}[/tex]

   = [tex]x^{\frac{-6}{3} + \frac{1}{3}}[/tex]

   = [tex]x^{\frac{-6+1}{3}}[/tex]

[tex]x^{b}[/tex] = [tex]x^{-\frac{5}{3}}[/tex]

∴b = [tex]-\frac{5}{3}[/tex]

[tex]y^{c}[/tex] = [tex]y^{-4}[/tex]×[tex]\sqrt[3]{y^{3}}[/tex]

   = [tex]y^{-4}[/tex]× [tex](y^{3})^{\frac{1}{3}}[/tex]

   = [tex]y^{-4}[/tex] × [tex]y[/tex]

   = [tex]y^{-4 + 1}[/tex]

[tex]y^{c}[/tex] = [tex]y^{-3}[/tex]

On solving the provided question, we can say that by unitary method, Total capital of the firm  = Rs. 85,000

The unit technique is an approach to problem-solving that involves first determining the value of a single unit, then multiplying that value to determine the required value. The unit method, to put it simply, is used to extract a single unit value from a supplied multiple. For instance, 40 pens would cost 400 rupees, or the price of one pen. The process for doing this may be standardized. a single country. anything that has an identity element. (mathematics, algebra) (Linear algebra, mathematical analysis, mathematics of matrices or operators) Its adjoint and reciprocal are equivalent.

A measurement unit is a standard quality used to express a physical quantity. Also it refers to the comparison between the unknown quantity with the known quantity.

Given that;

The expression is,

⇒ 3.4 × 10⁵ g . cm² / s²

Now, We know that;

Answer: D, 3x+12

Step-by-step explanation: Distributing a number means that you have to multiply the number by all of the numbers inside the parentheses. 3*x is 3x, and 3*4 is 12.  3x+12 is 3x+12.

Answer:

Step-by-step explanation:

There are several ways to approach this problem, but one common method is to use the complementary counting principle, which states that the number of favorable outcomes can be obtained by subtracting the number of unfavorable outcomes from the total number of outcomes. In this case, the favorable outcome is that the sample contains at least one defective phone, and the unfavorable outcome is that the sample contains no defective phones.

The number of possible samples of 4 phones out of 15 can be calculated as the number of combinations of 4 items from a set of 15, which can be written as:

C(15, 4) = 15! / (4! * (15 - 4)!) = 1365

The number of samples containing no defective phones can be calculated as the number of combinations of 4 phones out of the remaining 12 non-defective phones, which can be written as:

C(12, 4) = 12! / (4! * (12 - 4)!) = 495

So, the number of samples containing at least one defective phone can be calculated as:

1365 - 495 = 870

Therefore, out of the 1365 possible samples of 4 phones, 870 of them contain at least one defective phone.

Answer:

$416.67

Step-by-step explanation:

8% = 0.08

adding 8% to something means you add 0.08 of it

original = 100% = 1

original + 8% increase = 1 + 0.08 = 1.08

1.08 of original price = new price = 450

1.08 * original price = 450

450/1.08 = original price = $416.67

The points are scattered in the scatterplot and thus, a line would not be appropriate because the points follow a nonlinear pattern.

Hence, option b is the correct answer.

Numerous different kinds of associations between two variables can be found using a scatterplot.

When there is no pattern visible in the points on a scatterplot, a relationship has no correlation.

When the points on a scatterplot exhibit a pattern rather than a straight line, a relationship is non-linear.

When the points on a scatterplot exhibit a largely straight line pattern, a relationship is linear. We shall look at this relationship in detail.

The graph of the quadratic function can be seen on the image at the end.

The only way to graph or sketch a function by hand, is by finding some points on the graph and then connecting them.

To find the points we need to evaluate the quadratic equation.

if x = 0

y = 5*0^2 + 2 = 2

So we have the point (0, 2)

if x = 1

y = 5*1^2 + 2 = 7

So we have the point (1, 7)

if x = -1

y = 5*(-1)^2 + 2 = 7

So we have the point (-1, 7)

You made a profit of $382.50 from selling the 45 shares of the telecommunications company.

First we need to determine the total cost of purchasing those shares, and then subtract that from the total revenue from selling them.

The total cost of purchasing the 45 shares at a price of $63.00 per share is:

45 shares x $63.00 per share = $2,835.00

The total revenue from selling the 45 shares at a price of $71.50 per share is:

45 shares x $71.50 per share = $3,217.50

To calculate the profit, we subtract the cost from the revenue:

Profit = Revenue - Cost

Profit = $3,217.50 - $2,835.00

Answer:

The total number of boats Paul counted is 24 speed boats + 5 sail boats + 1 rowboat = 30 boats.

So, the experimental probability that the next boat he sees will be a sailboat is 5 sail boats / 30 boats = 1/6.

The experimental probability of an event is defined as the ratio of the number of times the event occurs to the total number of trials or observations.

In this case, Paul observed a total of 24 + 5 + 1 = 30 boats, of which 5 were sailboats.

Therefore, the experimental probability that the next boat Paul sees will be a sailboat is:

Experimental probability = number of sailboats / total number of boats

Experimental probability = 5 / 30

Experimental probability = 1/6

So the experimental probability of seeing a sailboat next is 1/6 or approximately 0.167.

The variance of the given frequency distribution is 60.92, and the standard deviation is option (b) 7.80.

To calculate the variance of a frequency distribution, we need to first find the mean or average of the data. The formula for calculating the mean is as follows:

mean (μ) = Σfx / Σf

where Σfx represents the sum of the products of each value and its corresponding frequency, and Σf is the sum of all the frequencies.

Using the given data, we can calculate the mean as follows:

μ = (43 + 85 + 119 + 175 + 204 + 243 + 32*1) / (3+5+9+5+4+3+1)

μ = 13.5

Next, we need to calculate the deviation of each data point from the mean. To do this, we subtract the mean from each value and square the result. The formula for this is:

(x - μ)²

Using this formula, we get the following deviations for each data point:

(4 - 13.5)² = 81.00

(8 - 13.5)² = 30.25

(11 - 13.5)² = 6.25

(17 - 13.5)² = 12.25

(20 - 13.5)² = 42.25

(24 - 13.5)² = 110.25

(32 - 13.5)² = 333.22

Next, we need to multiply each deviation by its corresponding frequency, and then sum up the results. The formula for this is:

Σf(x - μ)²

Using the above deviations and frequencies, we can calculate the sum of squares as follows:

Σf(x - μ)² = 381.00 + 530.25 + 96.25 + 512.25 + 442.25 + 3110.25 + 1 x 333.22

Σf(x - μ)² = 1827.48

Finally, we can calculate the variance by dividing the sum of squares by the total number of observations (Σf). The formula for variance is:

σ² = Σf(x - μ)² / Σf

Using the above values, we can calculate the variance as follows:

σ² = 1827.48 / 30

σ² = 60.92

The standard deviation is the square root of the variance. Therefore:

σ = √(60.92)

σ = 7.80

Therefore, the correction option is (b).
