No, the equation cannot be written with the given information. The distance from the catapult when the watermelon reached the maximum height is needed. Since the watermelon did not start on the ground, it cannot be assumed that the maximum was reached half the distance to the landing point.

Answer: y = 14.50x + 2.99

Step-by-step explanation:

The equation is y = mx + b

y is the total cost and x is the number of shirt

We know each shirt is $14.50, and she bought x shirts, so 14.50 is the slope

The 2.99 shipping fee is the y-intercept

So our equation is

y = 14.50x + 2.99

The probability that in any given period of 400 days there will be an accident on one day is 0.2707

Given that;

In a certain industrial facility, accidents occur infrequently. it is known that the probability of an accident on any given day is 0.005 and accidents are independent of each other.

n = 400, p = 0.005

Poisson distribution is given by;

e P(x) = (λˣe^λ ) / x!

Here, Mean(λ) = np

                        = 400*0.005

                        =2

The probability that there will be an accident on one day;

(P(x = 1)) = (λxe-λ)/x!

             = 2*e-2

             = 0.2707

The probability that in any given period of 400 days there will be an accident on one day is 0.2707

Step-by-step explanation:

Sara used 3/5 cup of milk in the recipe. The answer corresponds to option (B) in the given answer choices.

The total amount of liquid used by Sara in the recipe is 1 cup. Out of this 1 cup, Sara used 2/5 cup of vinegar. Therefore, the amount of milk she used would be the difference between the total amount of liquid used and the amount of vinegar used.

Mathematically, we can represent this as:

Amount of milk = Total amount of liquid - Amount of vinegar

Amount of milk = 1 cup - 2/5 cup

Simplifying the expression on the right side, we get:

Amount of milk = 5/5 cup - 2/5 cup

Amount of milk = 3/5 cup

Therefore, Correct option is B.

The angles are which alternate exterior angles include the following: A. ∠XWY and ∠STR.

Parallel lines can be defined as two (2) lines that are cut through by a transversal and they always have the same (equal) distance apart and never meet.

The alternate exterior angle theorem states that when two (2) parallel lines are cut through by a transversal, the alternate exterior angles that are formed lie outside the two (2) parallel lines, are located on opposite sides of the transversal, and are congruent angles.

In conclusion, we can logically deduce that both ∠XWY and ∠STR are alternate exterior angles because they lie outside the two (2) parallel lines and are located on opposite sides of the transversal.

Answer:

\(4 \frac{1}{9}x\) + \(12\frac{1}{3}\) = 0

Step-by-step explanation:

Based on 2x - 9y - 12 = 0

-9y = 12 - 2x

9y = -12 + 2x

y = \(-1\frac{1}{3} + \frac{2}{9} x\)

Therefore...

5x - 4y + 7 = 0

5x - 4(\(-1\frac{1}{3} + \frac{2}{9} x\)) + 7 = 0

5x + \(5\frac{1}{3}\)  - \(\frac{8}{9} x\) + 7 = 0

\(4 \frac{1}{9}x\) + \(12\frac{1}{3}\) = 0

The probability that a student scored is 0.8.

To find the probability that a student scored less than 600 or took less than 4 years of math.

We need to add the probabilities of each of these events occurring separately, and then subtract the probability of both events occurring together.

Let P(L) be the probability that a student scored less than 600 and P(M) be the probability that a student took less than 4 years of math.

We are not given the joint probability of both events, so we need to calculate it using the formula:

P(L and M) = P(L) + P(M) - P(L or M)

where P(L or M) is the probability that a student scored less than 600 or took less than 4 years of math.

Assuming that the events of scoring less than 600 and taking less than 4 years of math are independent, we can calculate their probabilities separately:

P(L) = 0.35 (given)

P(M) = 0.25 (given)

To calculate P(L or M), we add the probability of scoring less than 600 to the probability of taking less than 4 years of math, and then subtract the probability of both events occurring together:

P(L or M) = P(L) + P(M) - P(L and M)

We don't have the value of P(L and M), so we cannot directly calculate P(L or M). However, we know that the sum of probabilities of all possible events is equal to 1.

Therefore, we can use the formula:

P(not L and not M) = 1 - P(L or M)

where P(not L and not M) is the probability that a student scored 600 or more and took 4 or more years of math.

Since we know that the events of not scoring less than 600 and taking 4 or more years of math are complementary to scoring less than 600 or taking less than 4 years of math.

We can use the complement rule to calculate P(not L and not M):

P(not L and not M) = 1 - P(L or M)

= 1 - (P(L) + P(M) - P(L and M))

= 1 - (0.35 + 0.25 - P(L and M))

= 0.4 - P(L and M)

Now we need to find P(L and M) to calculate P(not L and not M). We are not given this probability directly, so we cannot use the product rule.

However, we know that the number of students who scored less than 600 and took less than 4 years of math is 80, and the total number of students is 400. Therefore, we can use the formula:

P(L and M) = number of students who scored less than 600 and took less than 4 years of math / total number of students

= 80 / 400

= 0.2

Substituting this value in the formula for P(not L and not M), we get:

P(not L and not M) = 0.4 - P(L and M)

= 0.4 - 0.2

= 0.2

Therefore, the probability that a student scored less than 600 or took less than 4 years of math is:

P(L or M) = 1 - P(not L and not M)

= 1 - 0.2

= 0.8

So the probability that a student scored less than 600 or took less than 4 years of math is 0.8.

Yoona will charge $20.75 to walk 8 dogs based on the trend of Yoona charges to walk dogs.

First, find the pattern in the amount that Yoona charges to walk each additional dog.

Additional cost to walk 2 dogs:

= 40 - 37.25

= $2.75

Additional cost to walk 3 dogs:

= 37.25 - 34.50

= $2.75

Additional cost to walk 4 dogs:

= 34.50 - 31.75

= $2.75

Every extra dog therefore leads to a fall in price by $2.75. For eight dogs, Yoona would charge:

= 40 - (7 x 2.75)

= 40 - 19.25

Answer: It will take 12 hours for the price of the jacket to decrease by $18

Step-by-step explanation: All you got to do for this problem is 18 divided by 1.50 to get $12.

Answer:

Mango = 0.5, Peach = 1.75

Step-by-step explanation:

Let x represent the price of mango

Let y represent the price of peach

Melanie: 8x + 6y = 14.50

Jaya: 4x + 7y = 14.25

Isolate for a variable in one of the equations (just pick a random one, you don't have to pick mine)

4x + 7y = 14.25 => x = (14.25 - 7y)/4 = 3.5625 - 7/4y

Plug into other equation

8x + 6y = 14.50

8(3.5625 - 7/4y) + 6y = 14.5

28.5 - 14y + 6y = 14.5

28.5 - 14.5 = 14y - 6y

14 = 8y

y = 1.75

4x + 7y = 14.25

4x + 7(1.75) = 14.25

4x + 12.25 = 14.25

4x = 2

A. The equation d = s * t shows relationship between the quantities.

B. They would cover a distance of 10 miles in 20 minutes.

C. Rounded to the nearest tenth, the biker would bike for 96.0 minutes.

What is distance?

Distance is the measure of the physical space between two objects or points. It is a scalar quantity that is usually measured in units such as meters, kilometers, miles, etc. In physics, distance is considered to be a fundamental concept and is often used in conjunction with time to calculate other physical quantities, such as speed and acceleration.

a. We can define the following variables:

t: time in minutes

d: distance traveled by the biker in miles

s: speed of the biker in miles per minute

Using these variables, we can write the equation d = s * t to represent the relationship between them.

b. If the biker rides for 20 minutes, we can use the equation d = s * t to find the distance traveled. Assuming the biker's speed is 0.5 miles per minute, we get:

d = 0.5 * 20 = 10 miles

Therefore, the biker would travel 10 miles in 20 minutes.

c. If the biker traveled 48 miles, we can use the equation t = d / s to find the time taken, where s is again assumed to be 0.5 miles per minute:

t = 48 / 0.5 = 96 minutes

Rounded to the nearest tenth, the biker would have ridden for 96.0 minutes to cover 48 miles.

A rectangle in Euclidean plane geometry is a quadrilateral with four right angles. You might also describe it as follows: a quadrilateral that is equiangular, which indicates that all of its angles are equal. The parallelogram might also have a straight angle. Squares are rectangles with four equally sized sides. A quadrilateral of the shape of a rectangle has four 90-degree vertices and equal parallel sides. As a result, it is sometimes referred to as an equirectangular rectangle. Because its opposite sides are equal and parallel, a rectangle is also known as a parallelogram.

Given that the length of the rectangular space is three times its breadth

The chamber has a 56-meter perimeter.

Assume that the room's width is x.

As a result, the room is three times as long.

The room's perimeter is now equal to 2(3x + x).

The correct response is d) All the above. The arithmetic mean is equal to the median, the median is equal to the mode, and the mode is equal to the arithmetic mean.

If the data are graphed symmetrically, the distribution demonstrates 0% skewness regardless of how long or fat the tails are. When the median of a data set is utilized, 50% of the data points in the collection have values lower than or equal to the median, and 50% of them have values greater than or equal to the median. The middle score in the set is known as the median. The first step in calculating the median is to order the data points from smallest to greatest. The median in an odd-numbered set will be the value that falls exactly in the middle of the list. You must determine the average of the two middle numbers in a set of even numbers. The average is determined by summing up each value individually and dividing that sum by the total number of observations.
