Answer:

2/15

Step-by-step explanation:

Probability calculates the likelihood of an event occurring. The likelihood of the event occurring lies between 0 and 1. It is zero if the event does not occur and 1 if the event occurs.

For example, the probability that it would rain on Friday is between o and 1. If it rains, a value of one is attached to the event. If it doesn't a value of zero is attached to the event.

Experimental probability is based on the result of an experiment that has been carried out multiples times

experimental probability that the next patient will be female and in

the age range 22-39 =  females in  the age range 22-39 / total number of patients

total number of patients = 56 / 420

To transform to the simplest form. divide both the numerator and the denominator by 28

Answer:

A. (x - 5)^2 + (y + 4)^2 = 9

Step-by-step explanation:

The standard equation of a circle is in the form:

(x - h)^2 + (y - k)^2 = r^2

where (h, k) is the center and r is the radius. We can substitute what we have:

(x - 5)^2 + (y + 4)^2 = 9

Answer:

D, I think. Screenshot attached with the points.

Step-by-step explanation:

We have given two points (0, 6) and (-8, 0). The third point (8, -6) will make a complete right-angle triangle.

A right-angle triangle is a triangle that has a side opposite to the right angle the largest side and is referred to as the hypotenuse. The angle of a right angle is always 90 degrees.

We have given two points  (0, 6) and (-8, 0). we want to find Which of the following points would create a right triangle.

Answer:

(4,2) or x=4, y=2

Step-by-step explanation:

As your question asks, we'll solve the system of equations by substitution, where we'll solve for the value of one variable and than substitute that value into the other equation and solve for the two variables

we're given the system:

2x+4y=16

3x-2y=8

Let's take the first equation:

you can isolate either x or y, but I'll do x for this problem

2x+4y=16

subtract 4y from both sides

2x=-4y+16

divide both sides by 2

x=-2y+8

now take the second equation (3x-2y=8) and substitute -2y+8 as x

3(-2y+8)-2y=8

do the distributive property

-6y+24-2y=8

combine like terms

-8y+24=8

subtract 24 from both sides

-8y=-16

divide by -8

y=2

we found the value of y. However, we also need to find the value of x

above, we said that x=-2y+8; since we found the value of y, we can substitute that value into the equation and find x

so:

x=-2(2)+8

x=-4+8

x=4

the answer is x=4, y=2. If you need it as a coordinate point, it's (4,2)

Hope this helps!

Answer:

Step-by-step explanation:

Slope of the line

[tex] = \frac{8 - 4}{1 - 3} \\ \\ = \frac{4}{ - 2} \\ \\ = - 2[/tex]

The estimated equation of line is y = 8x+ 20

A linear equation is defined as an equation in which the highest power of the variable is always one.

Two points on the line (5, 60), (3, 44)

[tex]y- y_1= \frac{y_2-y_1}{x_2-x_1} (x-x_1)[/tex]

[tex]y- 60 = \frac{60-44}{5-3} (x-5)[/tex]

[tex]y- 60 = \frac{16}{2} (x-5)[/tex]

[tex]y = 8 (x-5)+ 60[/tex]

[tex]y = 8x+ 20[/tex]

Hence, the estimated equation of line is y = 8x+ 20

Answer:

9.6 ounces of butter, 8 ounces of sugar, 12 ounces of flour, 4 eggs

Explanation: 20 / 16 = 4/5. 16 is four-fifths of 20. So multiply 4/5 with everything.

12 * 4/5 = 9.6 ounces

10 * 4/5 = 8 ounces

15 * 4/5 =  12 ounces

5 * 4/5 = 4 eggs

Answer:

30.2%

Step-by-step explanation:

Use the percent error formula:

| (experimental - actual) / actual | x 100

Plug in the experimental and actual values:

| (experimental - actual) / actual | x 100

| (56 - 43 ) / 43 | x 100

(13 / 43) x 100

= 30.2

So, the percent error is 30.2%

Answer:

4212 square feet.

Step-by-step explanation:

If the blueprint's scale is 1 inch : 9 feet.

Square both sides

(1in)² = (9ft)²

1in² = 81ft²

Given the  gym's  area as 52 square inches, hence;

52in² = x

Divide both expressions

1/52 = 81/x

x = 52 * 81

x = 4212ft²

Hence the area of the actual gym  is 4212 square feet.

Answer:

5.33 Seconds

Step-by-step explanation:

This is because you have to do the quadratic equation and solve.

The time required to hi the water is 5.33 seconds.

A quadratic equation is a second-order polynomial equation in a single variable x as ax^2+bx+c=0 with a ≠ 0 . A quadratic equation as an equation of degree 2, meaning that the highest exponent of this function is 2.

For the given situation,

The function is h(t)= -16t^2+16t+370

The roots of this function can be found by using the formula,

[tex]t=\frac{-b+\sqrt{b^{2}-4ac } }{2a}[/tex] or [tex]t=\frac{-b-\sqrt{b^{2}-4ac } }{2a}[/tex]

Here, a=-16, b=16, c=370

⇒ [tex]t=\frac{-16+\sqrt{16^{2}-4(-16)(370) } }{2(-16)}[/tex] or [tex]t=\frac{-16-\sqrt{16^{2}-4(-16)(370) } }{2(-16)}[/tex]

⇒ [tex]t=\frac{-16+\sqrt{23936} }{-32}[/tex] or [tex]t=\frac{-16-\sqrt{23936} }{-32}[/tex]

⇒ [tex]t=\frac{-16+154.712}{-32}[/tex] or [tex]t=\frac{-16-154.712}{-32}[/tex]

⇒ [tex]t=\frac{138.712}{-32}[/tex] or [tex]t=\frac{-170.712}{-32}[/tex]

⇒ [tex]t=-4.33[/tex] or [tex]t=5.33[/tex]

Time cannot be negative. So the value is 5.33.

Hence we can conclude that the time required to hi the water is 5.33 seconds.
