So the "back" of the arrow is on/above -20.

The arrow points to -12.

You added something to -20 to get to -12.

So the first number is -20. You added ? to get -12. -12 is the last number / the answer to the equation.

So the equation from what you have so far is -20 + ? = -12

You need to isolate the ? so that you know what it is.

So to get rid of the -20 (make it 0), you have to add 20. -20 plus 20 equals 0, which basically means it is gone. You also have to add 20 to -12. 20 plus -12 equals 8.

Now the equation is ? = 8.

So you know that the second number is 8.

The equation makes sense; -20 + 8 = -12.

Using the Central Limit Theorem, it is found that the standard error for this sample is of 1.67.

It states that for a population of standard deviation \(\sigma\), the sampling distribution of sample means of size n has standard error \(s = \frac{\sigma}{\sqrt{n}}\).

In this problem, we have that \(\sigma = 10, n = 36\), hence the standard error is given by:

\(s = \frac{10}{\sqrt{36}} = 1.67\)

The correct option is B. 39°, alternate interior angles have same measure.

What is interior angle?

An interior angle is an angle formed inside a polygon by two adjacent sides of the polygon. In other words, when you draw a straight line between two vertices (corners) of a polygon, the angle between the two sides of the polygon that meet at those vertices is an interior angle.

When a transversal line intersects two parallel lines, it creates several pairs of congruent or supplementary angles.

Alternate interior angles are one such pair of congruent angles, which are formed on opposite sides of the transversal and between the two parallel lines. Hence, we can say that ∠3 ≅ ∠6, and ∠5 ≅ ∠4 in this case.

We know that angles 3 and 6 are congruent because they are alternate interior angles formed by the transversal line and the two parallel lines.

Therefore, the measure of angle 6 is also 39°.

The sentence that best describes the paragraph is: "The pirates didn't believe Caesar would kill them because he was their prisoner." So, the correct option is c) Pirates didn’t believe Caesar will kill them because he was their prisoner.

The paragraph recounts the events of Caesar's kidnapping by pirates while crossing the Aegean Sea. Despite being held captive, Caesar maintained an attitude of superiority. The pirates demanded a ransom of 20 talents of silver, but Caesar insisted they ask for 50. This indicates that Caesar saw himself as more valuable than the initial ransom amount suggested by the pirates.

After the ransom was paid, Caesar did not forget the pirates' actions. He raised a fleet, pursued the pirates, and captured them. The sentence implies that the pirates didn't believe Caesar would actually kill them because he was their prisoner and they likely saw his promises as mere jest.

However, Caesar, true to his word, had the pirates crucified on his own authority.

This sequence of events highlights Caesar's determination, strategic thinking, and his ability to command respect even in dire circumstances. Despite being initially taken prisoner, he managed to turn the tables on the pirates, assert his authority, and exact his revenge. So, the correct option is c) Pirates didn’t believe Caesar will kill them because he was their prisoner.

Step-by-step explanation:

You cannot divide by zero because you will get an undefined value, and this will create a hole in the graph.

Answer:

\(y = \frac{2}{x\\}\)

Explanation:

Let's check all the answers to be sure we are correct!

Choice A)  y = 2x

The domain for y = 2x is represented by the interval (-∞,∞). This shows that the domain is all real numbers.

Choice B)  y = 2 + x

The domain is represented by the interval (-∞,∞). This shows that the domain is all real numbers.

Choice C)  \(y=\frac{2}{x}\)

We know that the denominator can not be equal to zero. You must remember this! So, now we find that the domain is represented by the interval,

                                              (-∞,0) ∩ (0,∞)

This shows that the domain is all real numbers except the number zero.

Choice D) \(y = x^{2}\)

The domain is represented by the interval (-∞,∞). This shows that the domain contains all real numbers.

Therefore, our answer is choice C!

The volume of a square pyramid with a base area of 12 cm and a height of 16 cm is calculated using the formula (1/3) x (base area) x (height). Substituting the values given, the volume is 768 cubic cm.

A square pyramid is a geometric solid with four triangular sides that meet at the apex, which is a single point. It also has a square base. The triangle faces are all right triangles that are congruent, which means they are identical in size and shape, with one leg equal to the height of the pyramid and the other two legs equal to the slant height of the pyramid.

A square pyramid with a base edge of 12 cm and a height of 16 cm has a base area of:

Area of square base = \((edge)^2 = 12^2\) = 144 sq. cm

The volume of the pyramid can be calculated using the formula:

Volume = (1/3) x (base area) x (height)

Substituting the values given:

Volume = (1/3) x 144 x 16

Volume = 768 cubic cm

Therefore, the volume of the square pyramid is 768 cubic cm.

Answer:

XY = 92 units

Step-by-step explanation:

Similar Shapes

Two shapes are similar if all their corresponding side measures are in the same proportion.

The triangles UVW and YVX are similar because their side lengths are in the proportion 1:2, given the tick marks provided in the drawing.

This means that the measure of VX is twice the measure of VW,

The measure of YV is twice the measure of UV

The measure of XY is twice the measure of UW

This last proportion gives the equation:

z + 46 = 2z

Solving for z:

z = 46

Thus, XY = z+46 = 92

XY = 92 units

Based on the cross-price elasticity of Demand, we can conclude that good X and good Y are substitutes.

Let's calculate the cross-price elasticity of demand using the given information:

a. Find the percentage change in quantity demanded of good Y:

Percentage Change in Quantity Demanded of Good Y = (New Quantity Demanded - Initial Quantity Demanded) / Initial Quantity Demanded * 100

Percentage Change in Quantity Demanded of Good Y = (6250 - 5000) / 5000 * 100 = 25%

b. Find the percentage change in the price of good X:

Percentage Change in Price of Good X = (New Price - Initial Price) / Initial Price * 100

Percentage Change in Price of Good X = (5 - 4) / 4 * 100 = 25%

Now, we can calculate the cross-price elasticity of demand:

Cross-Price Elasticity of Demand = Percentage Change in Quantity Demanded of Good Y / Percentage Change in Price of Good X

Cross-Price Elasticity of Demand = 25% / 25% = 1

b. Based on the calculated cross-price elasticity of demand, we can determine the types of goods:

If the cross-price elasticity of demand is positive (as in this case, where it is 1), it indicates that the two goods are substitutes. This means that when the price of good X increases, the quantity demanded of good Y also increases, suggesting that consumers view these goods as alternatives to each other.

Therefore, based on the cross-price elasticity of demand, we can conclude that good X and good Y are substitutes.

Let R be the radius in millions of miles and let t be the time in days. Assume that when t = 0 the radius is 20 million miles and increasing then  R(t) = 20 + 1.6sin(2πt/5.2).

The equation for a sine wave is y = A sin (Bx + C) where A is the amplitude, B is the frequency and C is the phase shift.

In this case, the amplitude is 1.6.

Since the radius changes by a maximum of 1.6 million miles.

The frequency is 2π/5.2 (one full cycle of the sine wave in 5.2 days)

The phase shift is 0, since when t = 0 the radius is increasing.

The equation then becomes R(t) = 20 + 1.6sin(2πt/5.2)

1) The value of x in the triangle is; x = 25

2) The measure of each interior angle is;

25°, 40° and 115°

Exterior angle = 65°

In a triangle, from the exterior angle property, we know that the exterior angle is always equal to the sum of the interior opposite angles. Thus, we say that any two triangles will be similar provided that their corresponding angles tend to be congruent and the length of their sides will be proportional.

Thus;

x + 15 + 25 = 3x - 10

3x - x = 25 + 15 + 10

2x = 50

x = 50/2

x = 25

The measure of each interior angle is;

25°

25 + 15 = 40°

180 - (25 + 40) = 115°

Exterior angle = 180 - 115 = 65°
