A dentist has male and female patients that range in ages from 10
years old to 50 years old and up as shown in the table. What is the
experimental probability that the next patient will be female and in
the age range 22-39? Enter your answer in simplified fraction
form.
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

La respuesta correcta para esta pregunta abierta es la siguiente.
Aunque no se anexaron opciones o incisos para contestar, podemos comentar lo siguiente.
Cada material en sus distintos estados de agregación, cambia de volumen de forma diferente, sin embargo todos lo hacen en cierta medida. A esta propiedad se le llama Estados de Agregación de la Materia.
Las substancias cambian su composición debido a la presión o al cambio de temperatura a la que son sometidos. A ese proceso se le conoce como el estado de agregación de la materia, cuando las moléculas y átomos que constituyen esa matera se ve sometido a una transformación en su composición.
Podemos reconocer comúnmente cuatro estados de transformación de la materia, que son, el estado de plasma, el estado gaseoso, el estado líquido y el estado sólido

The blueprint's scale is
1 inch : 9 feet. If the gym's
area is 52 square inches on the
blueprint, what is the actual
square footage of the gym?
The area of the actual gym
is_square feet.
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.

A pitcher of punch is 1/3 full. 5 people share the punch equally. How much of the remaining punch do they each get?
Answer:1 / 15 of the pitcher
Step-by-step explanation:
The pitcher is 1/3 full and 5 people want to equally share it.
The equal amount is found by dividing 1/3 by 5:
= 1/3 ÷ 5
= 1/3 * 1/5
= 1/15 of the pitcher
Each person gets 1/5 of the pitcher

The function f(t)=-16t^(2)+64 represents the height y (in feet ) of a water droplet t seconds after falling from an icicle. After how many seconds does the water droplet hit the ground
Answer:
The answer is two seconds
Step-by-step explanation:
Set the y to 0 as we are looking for the height when f(t) has hit the ground. Then factor and the two zeros of the function are -2 and 2. because the -2 is an answer that that cannot make sense for time in a real world scenario, the answer is the positive zero, or two. :-)

Step-by-step explanation:
Stella invested $6100 in an account paying interest rate of 6 1/2 % compounded monthly. Katherine invested $6100 in an account paying an interest rate of 6 5/8 % compounded quarterly. After 7 years how much more money would Katherine have in here account than Stella, to the nearest dollar
Answer:
Katherine would have $109.54 more than Stella.
Step-by-step explanation:
Giving the following information:
Stella:
Initial investment (PV)= $6,100
Interest rate (i)= 0.065/12= 0.0054 per month
Number of periods (n)= 7*12= 84
Katherine:
Initial investment (PV)= $6,100
Interest rate (i)= 0.06625/4= 0.0167
Number of periods (n)= 7*4= 28
To calculate the future value, we need to use the following formula:
FV= PV*(1 + i)^n
Stella:
FV= 6,100*(1.0054^84)
FV= $9,589.5
Katherine:
FV= 6,100*(1.0167^28)
FV= $9,699.04
Difference= $109.54
Katherine would have $109.54 more than Stella.

What is an expression? What is a triangle?A mathematical expression is a combination of terms separated by mathematical operators. For example : 2x + 3y + 6. A triangle is a polygon with three edges and three vertices. The sum of all the angles of a triangle is 180 degrees. Mathematically - ∠x + ∠y + ∠z = 180°There are different types of triangles such as - equilateral triangle , scalene triangle , isosceles triangle etc.
We have two triangles as shown in the image.
The coordinates of a triangle ABC are shifted 6 units downward and then the complete figure is reflected across the y - axis.
Therefore, the transformation given in option [1] is the correct transformation that maps ABC to DEF.

Total 109.75 108.85 23 22.5
The estimated regression line of Y on X is
Y^ = a +bX
and two normal equations are
∑Y = na + b∑X
∑XY= a∑X + b∑X²
Now X`= ∑X/ n= 22.5/5=4.5
Y`= ∑Y/ n= 23/5= 4.6
b= n∑XY- (∑X)(∑Y) / n∑X²- (∑X²)
Putting the values
b= 5(108.85) - (23)(22.5)/ 5(109.75)- (22.5)²
b= 544.25-517.5/ 548.75-506.25
b= 26.75 /42.5
b= 0.6294
and
a= Y`- bX~= 4.6- 0.6294(4.5)= 4.6-2.823= 1.767
Hence the
desired estimated regression line of Y on X is
Y^= 1.767 + 0.6294X
Y^= 1.77 +0.63X
The estimated regression co efficient b= 0.6294 indicates that the values of Y increase by 0.6294 units for a unit increase in X.

PLZ HELP, DUE TONIGHT!! Find the values of a and b such that f(x) is continuous at x=1
Answer:
a = 2, b = -4Step-by-step explanation:
To make the given piecewise function continuous we need:
ax² - b = 6 and 5ax + b = 6 at x = 1It gives us the system:
a(1²) - b = 6 ⇒ a - b = 65a(1) + b = 6 ⇒ 5a + b = 6Sum of the two:
a - b + 5a + b = 6 + 66a = 12a = 2Then b is:
