Answer:

Y will be 65°

Step-by-step explanation:

Since angle S is 65°, angle Y will also be 65°

What are similar shape ?

Similar shapes are shapes that have the same shape, but their sizes may vary. All equilateral triangles, squares of any side lengths are examples of similar objects. In other words, if two triangles are similar, then their corresponding angles are congruent and corresponding sides are in equal proportion.

Since quadrilateral QRST is similar to quadrilateral WXYZ, then angle Q = angle W , angle R = angle X and angle S = angle Y and angle T = angle Z.

Since angle S is 65° from the diagram shown, angle will be measured as 65°.

Answer:

The decimal 6.25 would be 6 25/100 as a mixed number. In lowest terms, it would be 6 1/4.

The total surplus at the equilibrium point is: $200,000

This is the maximum total surplus that can be achieved in the market for the digital camera.

To compute the maximum total surplus, we need to find the equilibrium quantity and price in the market for the digital camera, and then calculate the consumer and producer surplus at that point.

First, we need to set the demand and supply functions equal to each other to find the equilibrium quantity:

50 - 2P = 2P - 10

4P = 60

P = 15

Substituting this equilibrium price into either the demand or supply function, we can find the equilibrium quantity:

Q = 50 - 2(15) = 20

So the equilibrium price is $15, and the equilibrium quantity is 20,000 digital cameras.

Next, we can calculate the consumer and producer surplus at the equilibrium point. Consumer surplus is the difference between the maximum price a consumer is willing to pay for a good and the market price, summed over all consumers in the market. Producer surplus is the difference between the market price and the minimum price a producer is willing to accept for a good, summed over all producers in the market.

The demand function gives us the maximum price consumers are willing to pay for each quantity of digital cameras:

P = 25 - 0.5Q

So at the equilibrium quantity of 20,000 digital cameras, the maximum price consumers are willing to pay is:

P = 25 - 0.5(20) = 15

This is exactly the same as the market price, so there is no consumer surplus at the equilibrium point.

The supply function gives us the minimum price producers are willing to accept for each quantity of digital cameras:

P = 0.5Q - 5

So at the equilibrium quantity of 20,000 digital cameras, the minimum price producers are willing to accept is:

P = 0.5(20) - 5 = 5

The market price is $15, so the producer surplus is:

(15 - 5) * 20 = $200,000

Therefore, the total surplus at the equilibrium point is:

$200,000

This is the maximum total surplus that can be achieved in the market for the digital camera.

The angles in the quadrilateral are as follows;

x = 77°

y = 103 degrees

z = 52 degrees

The diagram above is a quadrilateral. The angles x, y and z can be found as follows:

x + 103 = 180(sum of angles on a straight line)

x = 180 - 103

x = 77 degrees

Therefore,

y = 103 degree(vertically opposite angles)

Vertically opposite angles are congruent.

The sum of angles in a triangle is 180 degrees.

Therefore,

103 + 25 + z = 180

z = 180 - 128

z = 52 degrees.

The formula for the volume of a cone, V = (1/3)·π·r²·h, indicates that doubling the radius, quadruples the volume while doubling the height doubles the volume. Therefore;

A cone is a three dimensional figure formed by lines that extend between a point and the circumference of the circular base, where the point is located on the a line perpendicular to and passing through the center of the circular base.

The formula for the volume of a cone is; V = (1/3) × π × r² × h

Where;

V = The volume of the cone

r = The radius of the cone

h = The height of the cone

Therefore;

When the radius is doubled, we get;

V₁ = (1/3) × π × (2·r)² × h = (1/3) × π × 4 × r² × h = 4 × (1/3) × π × r² × h

When the radius of the cone is doubled, the volume of the cone increases 4 times the initial volume

When the height of the cone is doubled, we get;

V₂ = (1/3) × π × r² × 2·h = 2 × (1/3) × π × r² × h = 2·V

When the height of the cone is doubled, the volume of the cone is doubled.

Therefore, doubling the radius of the cone which increases the volume to four times the initial volume has the greater effect on the volume of the cone than doubling the height which doubles the volume of the cone.

Answer: To find the critical value for a 80.4% confidence interval for a normal approximation of a binomial distribution, we need to find the z-score that corresponds to the 80.4% confidence level. We can do this using a standard normal table or using a z-score calculator.

Using a z-score calculator, we can find that the z-score corresponding to 80.4% confidence level is approximately 0.931. This means that 80.4% of the data falls within 0.931 standard deviations of the mean.

So, the critical value that corresponds to a confidence level of 80.4% is approximately 0.931.

Step-by-step explanation:

If Mr.Curry has 264 pictures on 4 shelves in his house.

The number of pictures on each shelf can be found by dividing the total number of pictures by the number of shelves:

264 ÷ 4 = 66

So, there are 66 pictures on each shelf.

To find the number of tens Mr. Curry regrouped as ones, we can use long division to see the process of dividing 264 by 4.

When dividing 264 by 4, the first step is to divide 2 by 4, which gives a quotient of 0 with a remainder of 2. Then, you bring down the next digit (6), and form the number 26. Dividing 26 by 4 gives a quotient of 6 with a remainder of 2. Finally, you bring down the last digit (4), and form the number 264. Dividing 264 by 4 gives a quotient of 66 with no remainder.

Therefore, Mr. Curry regrouped 2 tens as ones (or 20 as 10 + 10), which is the same as regrouping 20 ÷ 10 = 2 tens as ones.

on solving the provided question we can say that length of the major arc angle  is [tex](29/6)\pi or 4.83\pi[/tex].

In Euclidean geometry, an angle is a shape that is made up of two rays, known as the angle's sides, that meet at a point in the middle known as the angle's vertex. Two rays may combine to form an angle in the plane where they are positioned. When two planes collide, an angle is also created. These are referred to as dihedral angles. An angle in plane geometry is the possible configuration of two rays or lines that share a termination. The origin of the English term "angle" is the Latin word "angulus," which meaning "horn." The vertex is the point where the two rays, also known as the sides of the angle, converge.

The measure of the complement of angle is 45 degrees.

Let's call the measure of the angle "x". The complement of the angle is defined as 90 degrees minus the measure of the angle, so the complement of the angle is 90 - x.

If the measure of the angle is less than its complement, then we can write the following inequality:

x < 90 - x

Now we can isolate x by subtracting x from both sides:

0 < 90 - 2x

And then dividing both sides by -2:

0 > -45 + x

Finally, subtracting x from both sides:

-x > -45

So, we have:

x < 45

So, the complement of the angle is 90 - x, which is greater than 90 - 45 = 45 degrees.

The probability of hitting the bullseye if the dart is thrown 40 times is approx. 3 times.

The quantity of occurrences of an event is referred to as its frequency. The concept of relative frequency is experimental rather than theoretical. It is experimental, therefore if we repeat the trials, we can get different relative frequencies. To determine the frequency, we must first:

Number of occurrences for the entire population

Frequency count for a particular demographic segment

If we know the two frequencies mentioned above, we can use the following formula to get the relative frequency probability. A subgroup's formula is as follows:

Subgroup Count / Overall Count: Relative Frequency

Given that, a player hits the bullseye with a dart 8% of the time.

Step-by-step explanation:

Measure of length in scale drawing = Measure of actual length

                                             6 inches = 24 feet

                                               ∴ 1 inch = [tex]\frac{24}{6}[/tex] feet

∴Unit multiplier applied:

                  ∴1 inch in scale drawing = 4 feet of actual measurement

         
Measure of width in scale drawing = Measure of actual width

                                             x inches = 40 feet

                                           ∴ x inches = (40 feet) × ([tex]\frac{1 inch}{4 feet}[/tex])

Measure of width in scale drawing   = 10 inches

Area of rectangular floor in the scale drawing = (Length) × (Width)

                                                                                = (6 inches) × (10 inches)

                                                                                = 60 square inches
