Answer:

Let's call the number of hours before 8 P.M. that Meghan babysat "x", and the number of hours after 8 P.M. "y". We can set up two equations based on the information given:

5x + 8y = 26 (this is the total amount she earned)

x + y = total number of hours she babysat

We can solve for one of the variables in terms of the other and substitute it into the first equation:

y = total number of hours - x

5x + 8(total number of hours - x) = 26

5x + 8total number of hours - 8x = 26

3x = 26 - 8total number of hours

x = (26 - 8total number of hours)/3

Now we can try different values for the total number of hours she babysat to see if we get a whole number for x:

If she babysat for 1 hour, x = (26 - 8)/3 = 6, which is not a whole number.

If she babysat for 2 hours, x = (26 - 16)/3 = 3, which is a whole number.

If she babysat for 3 hours, x = (26 - 24)/3 = 0.67, which is not a whole number.

So we know she babysat for 2 hours before 8 P.M. and 1 hour after 8 P.M.:

5(2) + 8(1) = 18

2 + 1 = 3 total hours babysat

Therefore, Meghan babysat between 6 P.M. and 9 P.M.

Second-degree functions are known as quadratics.

Quadratic Functions

Quadratic functions are second-degree. This means that the highest exponent of any term is 2. When graphed, quadratic functions form parabolas, which look like U-shape.

To find the a, b, and c values of a quadratic, the function must be set equal to zero and in standard form. Remember that standard form is when the terms are written in descending order of degree (exponent). This equation given is already set equal to zero and in standard form.

Standard Form

When in standard form, quadratics are written like ax^2+bx+c. The coefficients go in alphabetic order.

This means that for the given equation: a = 1, b = 3, c = -4. These values can be used in different ways, mainly the quadratic equation.

To simplify 3(w+11) /6w, we can first simplify the numerator by distributing the 3:

3(w+11) = 3w + 33

Now we have:

(3w + 33) / 6w

We can further simplify by factoring out a 3 from the numerator:

3(w + 11) = 3 * 1(w + 11)

So we have:

(3 * 1(w + 11)) / 6w

The 3's cancel out, leaving:

(w + 11) / 2w

Therefore, the fully simplified expression is (w + 11) / 2w.

Answer: To prove the relationship between segments AB and CD, we need to determine if they are parallel, perpendicular, or neither.

First, let's find the slope of line AB:

y − 9 = −4(x + 1)

y − 9 = −4x − 4

y = −4x + 5

So the slope of line AB is -4.

Now let's find the slope of line CD:

y − 6 = one fourth(x − 3)

y − 6 = (1/4)x − (3/4)

y = (1/4)x + (21/4)

So the slope of line CD is 1/4.

Since the slopes of the two lines are not equal and not negative reciprocals, they are neither parallel nor perpendicular. Therefore, we cannot determine the relationship between segments AB and CD based on the given information.

Step-by-step explanation:

(a) The probability that at least half the patients are under 15 years old is  0.01562.

(b)  The probability that from 2 to 5 patients are 65 years old or older is, 0.92179.

(c) The probability that from 2 to 5 patients are 45 years old or older is, 0.9216.
(d) The probability that all the patients are under 25 years of age is  0.00065.

(e) The probability that all the patients are 15 years old or older is 0.16777.

(a) We can model this situation as a binomial distribution with 8 trials, where success is a visitor age being under 15 years old and the probability of success is unknown.

To find the probability that at least half the patients are under 15 years old, we can use the binomial cumulative distribution function.

Assume that the probability of success (visitor age under 15) is 0.5,

The probability of at least half of the patients being under 15 is,

⇒ P(X ≥ 4) = 1 - P(X < 4) = 1 - (P(X = 0) + P(X = 1) + P(X = 2) + P(X = 3))

                   = 1 - (0.03125 + 0.21875 + 0.42188 + 0.3125)

                    = 0.01562

Therefore,

The probability that at least half the patients are under 15 years old is  0.01562.

(b) To find the probability that from 2 to 5 patients are 65 years old or older,

First find the probability of each individual case and then add them up. The probability of success (visitor age being 65 or older) on a single trial is unknown.

Assume it is 0.2. Then,

⇒ P(X = 2) = 0.29376 P(X = 3)

                 = 0.32496 P(X = 4)

                 = 0.21499 P(X = 5)

                 = 0.08808

Therefore, the probability that from 2 to 5 patients are 65 years old or older is,

⇒ P(2 ≤ X ≤ 5) = P(X = 2) + P(X = 3) + P(X = 4) + P(X = 5)

                           = 0.29376 + 0.32496 + 0.21499 + 0.08808

                           = 0.92179

(c) To find the probability that from 2 to 5 patients are 45 years old or older,

We need to use a different probability of success for each individual case, depending on the age of the patients scheduled for the day.

Assume that the probability of success (visitor age being 45 or older) is 0.6. Then,

⇒ P(X = 2) = 0.2304 P(X = 3)

                 = 0.3456 P(X = 4)

                 = 0.2592 P(X = 5)

                 = 0.0864

Therefore, the probability that from 2 to 5 patients are 45 years old or older is,

⇒ P(2 ≤ X ≤ 5)  = P(X = 2) + P(X = 3) + P(X = 4) + P(X = 5)

                            = 0.2304 + 0.3456 + 0.2592 + 0.0864

                            = 0.9216

(d) To find the probability that all the patients are under 25 years of age, we can assume that the probability of success (visitor age under 25) is unknown.

Assume it is 0.3. Then,

⇒ P(X = 8) = [tex]0.3^8[/tex]

                 = 0.00065

Therefore, the probability that all the patients are under 25 years of age 0.00065.

(e) To find the probability that all the patients are 15 years old or older, we can assume that the probability of success (visitor age being 15 or older) is unknown.

Assume it is 0.8. Then,

⇒ P(X = 8) = [tex]0.8^8[/tex]

                 = 0.16777

Therefore, the probability that all the patients are 15 years old or older is approximately 0.16777.

The area of the circle given a diameter of 24 inches is 452 square centimeters

To calculate the area of a circle with a diameter of 24cm, we first need to find the radius.

The radius is half the diameter, so it would be 12cm.

Once we have the radius, we can use the formula for the area of a circle, which is A = πr².

Substituting the value of the radius into the formula gives us:

A = π(12)² = 144π

Answer:

40 and 27

Step-by-step explanation:

Answer:Let's call the two numbers x and y.

From the problem, we know that:

x + y = 67 (equation 1)

and

x - y = 13 (equation 2)

To solve for x and y, we can use the method of elimination. We can add equations 1 and 2 to eliminate y:

(x + y) + (x - y) = 67 + 13

Simplifying this equation, we get:

2x = 80

Dividing both sides by 2, we get:

x = 40

Now we can use equation 1 to solve for y:

x + y = 67

40 + y = 67

Subtracting 40 from both sides, we get:

y = 27

Therefore, the two numbers are 40 and 27.

The original price of the car is 85,000. b. The car loses 3,400 in value per year. c. The car will totally depreciate after 25 years. This is because 85,000 divided by 3,400 equals 25.

Value in math is the result of a mathematical operation or equation. It is a number or quantity assigned to a mathematical expression. Value can also refer to the worth of an object or activity, such as the value of a specific type of currency or the value of a certain action. Value can refer to the magnitude of a number or a quantity relative to other numbers or quantities, such as the value of a particular number on a scale.

a.  The original price of the car can be calculated by setting x=0 in the equation, which gives 85,000. This means that the original price of the car is 85,000.

b. The value of the car decreases by 3,400 per year. This is calculated by looking at the coefficient of x in the equation, which is −3,400. This means that for every year that passes, the value of the car decreases by 3,400.

c. The car will take 25 years to totally depreciate. This is calculated by setting the equation equal to 0 and solving for x. The equation 0 = −3,400x + 85,000 can be rearranged to x = 25. This means that the car will take 25 years to totally depreciate.

Answer:

Step-by-step explanation:

Let's start with the initial amount of gravel in the mound, which is g pounds.

After 300 pounds are added, the total amount of gravel in the mound becomes:

g + 300

Then, two orders of 600 pounds are sold and removed from the mound. So, the total amount of gravel in the mound after these two orders are sold becomes:

g + 300 - 2(600) = g + 300 - 1200 = g - 900

Finally, we know that at the end of the day, the mound has 1400 pounds of gravel. So, we can set up an equation:

g - 900 + 300 = 1400

Simplifying this equation, we get:

g - 600 = 1400

Adding 600 to both sides, we get:

g = 2000

Therefore, the initial amount of gravel in the mound was 2000 pounds.

where "a" is the expression to be added.

To solve for "a", we can isolate "a" on one side of the equation by adding 7 to both sides:

3x - 7 + a + 7 = 0 + 7

Simplifying the left side, we get:

3x + a = 7

Therefore, the expression that must be added to 3x - 7 to equal 0 is:

a = -3x + 7

We can check that this is correct by substituting -3x + 7 for "a" in the original equation:

3x - 7 + (-3x + 7) = 0

Simplifying the left side, we get:

3x - 3x - 7 + 7 = 0
