The information in assertion 2 that says Retrievers make up 15 percent of the dogs at the event is untrue.

A value or ratio that may be stated as a fraction of 100 is referred to as a percentage in mathematics. If we need to compute a percentage of a number, we should divide it by its whole and then multiply it by 100. The proportion, therefore, refers to a component per hundred. Per 100 is what the term percent signifies. The letter "%" stands for it.

Given, 35% of the dogs at a dog show are German shepherds. 10% of the dogs are poodles, 45% of the dogs are spaniels, and the rest were retrievers.

Since the rest dog breed was retrievers,

Thus, retrievers = 100- 45-35-10

retrievers = 10%

Therefore, statement 2 which states Retrievers account for 15 percent of the dogs at the show is incorrect.

Answer: We can start by using the following formula to find the time it takes for David to catch up with James:

time = (James' lead) / (David's rate - James' rate)

In this case, James' lead is 6 hotdogs, and we know that James eats 1 hotdog every 2 minutes, so his rate is 1/2 hotdog per minute. David's rate is 1.25 hotdogs per minute.

So, substituting these values into the formula:

time = (6) / (1.25 - (1/2))

time = 6 / (0.75)

time = 8 minutes

So it takes David 8 minutes to catch up with James.

Step-by-step explanation:

As the cable between the towers has the shape of a parabola, the height of the cable 200 feet from a tower is 40 feet.

Consider the origin of coordinate system at the bridge level midway between the towers and the cable has the shape of a parabola. It is the vertex of the parabola. The general equation of a parabola is given by y = a(x – h)^2 + k where (h, k) denotes the vertex. Hence, based on the provided information, the equation is;

y = a^x^2

The height of the tower above the road is 160 feet which is 400 feet from the vertex. Hence, x = 400 feet and y = 160 feet.

Substituting the values,

160 = a^(400)^2

a = 0.001

Hence, the equation of the given parabola is:

y = 0.001x^2

In order to calculate the height of the cable at 200 feet from the tower, the value of x = 400 – 200 = 200 feet

y = 0.001(200)^2 = 40 feet

Note: The question is incomplete. The complete question probably is: The towers of a suspension bridge are 800 feet apart and rise 160 feet above the road. The cable between the towers has the shape of a parabola and the cable just touches the sides of the road midway between the towers. What is the height of the cable 200 feet from a tower?

Answer:

see below

Step-by-step explanation:

length = 10

circumference = 2πr = 8 π, so r=4

8π=25.12

cut half so length = 5, so lateral surface = 8π*5 = 40π =125.6

top circle area = πr² = 3.14*4² = 3.14 *16 = 50.24

top & bottom = 2*50.24 = 100.5

so total surface of EACH after cut in half = 100.5+125.6 =226.1

TWO of them = 2*226.1 =452.2

We have designed a situation where the probability of one event (event A) is 1/5 and the probability of another event (event B) is 1/10.

To quantify the probability of each event, we can define the following events:

Then, the probability of event A is 1/5, since 1 in every 5 units of product A is defective. Similarly, the probability of event B is 1/10, since 1 in every 10 units of product B is defective.

Now, let's consider a scenario where the company receives an order for 100 units of products, with 60 units of product A and 40 units of product B. The company wants to determine the probability of the following events:

To calculate the probability of event C, we need to consider the probability of selecting a defective unit from product A and from product B, and the proportion of each product in the order. Since the order has 60 units of product A and 40 units of product B, the probability of selecting a unit of product A is 60/100 = 3/5, and the probability of selecting a unit of product B is 40/100 = 2/5.

Using the probabilities of event A and event B, we can calculate the probability of selecting a defective unit from product A or from product B as follows:

Therefore, the probability of event C can be calculated as follows:

P(C) = P(A) * P(A in order) + P(B) * P(B in order)

= (1/5 * 3/5) + (1/10 * 2/5)

= 3/25

So the probability of selecting a defective unit from the order is 3/25.

To calculate the probability of event D, we can use the complement rule, which states that the probability of an event and its complement (i.e., the event not happening) add up to 1. Therefore, the probability of event D can be calculated as follows:

P(D) = 1 - P(C)

= 1 - 3/25

= 22/25

So the probability of selecting a unit from the order at random and finding that it is not defective is 22/25.

In summary, we have designed a situation where the probability of one event (event A) is 1/5 and the probability of another event (event B) is 1/10. We have also calculated the probability of two other events (event C and event D) in a scenario where a manufacturing company produces two types of products, with different probabilities of defects, and receives an order with a certain proportion of each product.

The coordinates of point C are C(0,-sqrt(36 - x²))

An equilateral triangle has all sides of equal length and all angles of 60 degrees. Since the triangle is in the fourth quadrant, so we know that both the x and y coordinates of point C must be negative.

We can use the distance formula to find the length of the sides of the triangle:
AB = sqrt((0 - 0)² + (-6 - 0)²) = 6
BC = sqrt((x - 0)²+ (y - 0)²) = AC = sqrt((x - 0)² + (y - (-6))²) = sqrt(x² + (y + 6)² = 6

We may now use the notion that all angles in an equilateral triangle equal 60 degrees. We know that point A is at (0,-6) and point B is at (0,0), therefore we can use the slope of line AB and the length of the side to compute point C's coordinates.


Line AB has a slope of (0 - (-6))/(0 - 0) = 6/0 = undefined.The slope of a line perpendicular to AB is the negative reciprocal of AB's undefined slope; so, line AB is parallel to the x-axis. So C(x,y) has the same x-coordinate as B(0,0) but a different y-coordinate.

The length of the side is 6, so we can use this information to find the y-coordinate of point C:
y = sqrt(6² - x²) = sqrt(36 - x²)= -sqrt(36 - x²)

So, the coordinates of point C are C(0,-sqrt(36 - x²))

The length of segment EF is 6 cm.

The distance between two ends determines the length of a segment.

A segment may be straight, curved, or both straight and curved.

As the distance between two points on a line, a straight segment is the most basic kind of segment. The positions at the segment's ends are known as the endpoints.

It is possible to determine the length of a straight segment by first calculating the difference between the x- and y-coordinates of the two endpoints.

To determine the overall length of the segment, this information is then combined together. It is slightly more difficult to measure a piece that is curved.

This is so because a curved segment's length is frequently different at each location.

Mrs. Magsanoc covered 3/8 of the pizza before the phone rang.

Mr. Magsanoc covered 1/3 of the pizza while she was away.

To add the two portions, we need to find a common denominator, which is the least common multiple of 8 and 3. That is 24.

3/8 of the pizza is (3/8) * (24/8) = 3/24

1/3 of the pizza is (1/3) * (24/3) = 8/24
