Plug in 2 known values to solve.

Question

[tex]a^2+b^2 = c^2\\(8)^2 + (3)^2 = c^2[/tex]

64 + 9 = c^2

c^2 = 73

Find the square root of both sides.

[tex]\sqrt{c^2} = \sqrt{73}[/tex]

The equilibrium price is 12 and the equilibrium quantity is 400.

It should be noted that on order to fund equilibrium price and quantity, we've to equate the quantity supplied and demanded. This will be:

Qd = 1060 - 55p

Qs = -200 + 50p

Qd = Qs

1060 - 55p = -200 + 50p

Collect like terms

-55p - 50p = -200 - 1060

-105p = -1260

Divide

p = 1260 / 105

p = 12

The equilibrium price is 12

Equilibrium quantity = -200 + 50p

= -200 + 50(12)

= -200 + 600

The midrange for the data items in the given frequency distribution is 30.5.

Generally, To find the midrange for the data items in the given frequency distribution, we need to calculate the midpoint of each score range. The midpoint of a range is calculated by taking the average of the lower and upper bounds of the range.

For the first score range (29-30), the lower bound is 29 and the upper bound is 30, so the midpoint is (29 + 30) / 2 = 29.5.

For the second score range (30-31), the lower bound is 30 and the upper bound is 31, so the midpoint is (30 + 31) / 2 = 30.5.

Therefore, the midrange for the data items in the given frequency distribution is 30.5.

The horizontal component of the force vector is 260 pounds, and the vertical component is 150 pounds. (Option B).

To find the horizontal and vertical components of the force vector, we can use trigonometry. The horizontal component is the force acting in the direction parallel to the ground (x-axis), and the vertical component is the force acting in the direction perpendicular to the ground (y-axis).

Given that the force is 300 pounds and makes a 30° angle with the ground, we can calculate the components as follows:

Horizontal component (F_horizontal) = Force * cos(angle)

Vertical component (F_vertical) = Force * sin(angle)

Inserting in the values:

Horizontal component (F_horizontal) = 300 pounds * cos(30°)

Vertical component (F_vertical) = 300 pounds * sin(30°)

Now, let's calculate:

Horizontal component (F_horizontal) = 300 pounds * 0.866 (rounded to 3 decimal places, cos(30°) ≈ 0.866)

F_horizontal ≈ 259.8 pounds

Vertical component (F_vertical) = 300 pounds * 0.5 (rounded to 3 decimal places, sin(30°) ≈ 0.5)

F_vertical ≈ 150 pounds

Therefore, the required components of the force vector are approximately 260 pounds and 150 pounds.

To calculate the amount of commission that Nancy Bell earned last month, we can use the following formula:

Commission = Sales * Commission Rate

In this case, the sales are $59,400 and the commission rate is 14%, so the commission is:

Commission = $59,400 * 14% = $8,356

To calculate Nancy's gross pay, we can add her salary to her commission:

Gross Pay = Salary + Commission

Gross Pay = $1,710 + $8,356 = $10,066

Therefore, Nancy earned $8,356 in commission and her gross pay was $10,066.

When faced with an instant choice requirement, the availability heuristic enables people to make decisions fast. When you are trying to decide, a lot of connected incidents or circumstances could pop into your head right away. You can conclude that some events are more common or likely than others as a result.

You tend to overestimate the possibility and likelihood of similar situations happening in the future and give this information more weight.

the area of the triangle ABC is found by using the formula 1/2 * (base * height). Here, the base is 0 and the height is 1. Thus, the area of the triangle ABC = 0.5.

Let x = 0, y = 1 in 5x2y = 31

31 = 0

Thus, the point B is (0, 0).

The area of the triangle ABC = 1/2 * (0 * 1) + (0 * 1) + (1 * 0) = 0.5.

The equation of line L is given as 5x2y = 31. To find the point B, we need to substitute x = 0 in the equation. Doing so, we get 31 = 0, which means that the point B lies on the y-axis at (0, 0).

Next, since the line M is perpendicular to L and passes through A, we can assume that it is a horizontal line passing through (0, 1). Thus, the point C is the point of intersection of L and M, which is (1, 0).

Finally, the area of the triangle ABC is found by using the formula 1/2 * (base * height). Here, the base is 0 and the height is 1. Thus, the area of the triangle ABC = 0.5.

Step-by-step explanation:

The logical statement [tex]$(a \wedge b) \rightarrow(b \vee c)$[/tex] is a tautology. Hence, Option B is the most appropriate answer to the given question.

A tautology is a logical statement where the conclusion is always equivalent to the premise. No matter what the individual parts are, the result is always a true statement; i.e. a tautology is always true. The opposite of tautology is either a contradiction or a fallacy.

a. let us check the first option.

[tex](a \vee b) \rightarrow(b \wedge c)=(a+b)^{\prime}+b c[/tex]

[tex](a \vee b) \rightarrow(b \wedge c)=a^{\prime} b^{\prime}+b c[/tex]

Therefore, [tex]$(a \vee b) \rightarrow(b \wedge c)$[/tex] is a contingency and not a tautology.

b. let us check the second option.

[tex](a \wedge b) \rightarrow(b \vee c)=a b \rightarrow b+c[/tex]

[tex](a \wedge b) \rightarrow(b \vee c)=(a b)^{\prime}+b+c[/tex]

[tex](a \wedge b) \rightarrow(b \vee c)=a^{\prime}+b^{\prime}+b+c[/tex]

[tex](a \wedge b) \rightarrow(b \vee c)=a^{\prime}+1+c[/tex]   (since, b' + b = 1)

[tex](a \wedge b) \rightarrow(b \vee c)=1.[/tex]

Therefore, [tex]$(a \wedge b) \rightarrow(b \vee c)$[/tex] is a tautology.

c. let us check the third option.

[tex](a \wedge b) \rightarrow(b \rightarrow c)=(a+b) \rightarrow\left(b^{\prime}+c\right)[/tex]

[tex](a \wedge b) \rightarrow(b \rightarrow c)=(a+b)^{\prime}+b^{\prime}+c[/tex]

[tex](a \wedge b) \rightarrow(b \rightarrow c)=a^{\prime} b^{\prime}+b^{\prime}+c[/tex]

[tex](a \wedge b) \rightarrow(b \rightarrow c)=b^{\prime}+c[/tex]

Therefore, [tex]$(a \wedge b) \rightarrow(b \rightarrow c)$[/tex] is contingency but not a tautology.

d. let us check the fourth option.

[tex](a \rightarrow b) \rightarrow(b \rightarrow c)=\left(a^{\prime}+b\right) \rightarrow\left(b^{\prime}+c\right)[/tex]

[tex](a \rightarrow b) \rightarrow(b \rightarrow c)=\left(a^{\prime}+b\right)+b^{\prime}+c[/tex]

[tex](a \rightarrow b) \rightarrow(b \rightarrow c)=a b^{\prime}+b^{\prime}+c[/tex]

[tex](a \rightarrow b) \rightarrow(b \rightarrow c)=b^{\prime}+c[/tex]

Therefore, [tex]$(a \rightarrow b) \rightarrow(b \rightarrow c)$[/tex] is contingency but not a tautology.

Answer:

To have 4 times as many apples as bananas, Amadou could have bought 4 apples for every 1 banana, or 8 apples for every 2 bananas, or 16 apples for every 4 bananas.

4 apples : 1 banana

8 apples : 2 bananas

16 apples : 4 bananas

We can use the fact that the total cost of the apples and bananas was $9 to determine the number of apples and bananas that Amadou bought. Since each apple costs $1, Amadou bought 9 apples if he bought no bananas, or 7 apples if he bought 2 bananas, or 5 apples if he bought 4 bananas.

9 apples : 0 bananas

7 apples : 2 bananas

5 apples : 4 bananas

Therefore, the possible combinations of apples and bananas that Amadou could have bought are 9 apples and 0 bananas, 7 apples and 2 bananas, or 5 apples and 4 bananas.
