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.
probability that the committee will be made up of all math teachers = total number of maths teacher / total number of teachers

what is angle 3 is complement of angle 4 and m/4 = 47 degrees. find m angle 3??
Answer:
m= 188 and Angle 3 = 90-47 = 43
Step-by-step explanation:
Answer:
[see below]
Step-by-step explanation:
From the question given, angle 3 is a complement of angle 4, and angle 4 is 47 degrees.
Complementary angles add up to 90 degrees.
[tex]90 - 47 = 43[/tex]
Angle three should measure 43 degrees.

En 3 paquetes iguales hay 24 velitas en total. A) ¿Cuántas habrá en 19 paquetes iguales? B) ¿Cuántos paquetes iguales a estos se podrían armar con 320 velitas?
Answer:
A) En 19 paquetes habrá 152 velitas.
B) Se podrían armar 40 paquetes iguales con 320 velitas.
Step-by-step explanation:
La regla de tres simple directa consiste en una relación de cantidades con proporcionalidad directa, que se da cuando dadas dos cantidades correspondientes son magnitudes directamente proporcionales. Esto es, si al multiplicar o dividir una de ellas por un número, la otra queda multiplicada o dividida por ese número.
La regla de tres simple permite hallar un cuarto término de una proporción conociendo los otros tres.
Siendo a, b y c datos conocidos y x la incógnita, la regla de tres simple se aplica de la siguiente manera:
a ⇒ b
c ⇒ x
Entonces: [tex]x=\frac{c*b}{a}[/tex]
A) En este caso la regla de tres simple se aplica de la siguiente manera: si en 3 paquetes hay 24 velitas, en 19 paquetes ¿Cuántas velitas habrá?
3 paquetes → 24 velitas
19 paquetes → x
Entonces [tex]x=\frac{19 paquetes*24 velitas}{3 paquetes}[/tex]
x= 152 velitas
En 19 paquetes habrá 152 velitas.
B) En este caso la regla de tres simple se aplica de la siguiente manera: si hay 24 velitas en 3 paquetes, hay 320 velitas ¿Cuántos paquetes se podrán armar?
24 velitas → 3 paquetes
320 velitas → x
Entonces [tex]x=\frac{320 velitas*3 paquetes}{24 velitas}[/tex]
x= 40 paquetes
Se podrían armar 40 paquetes iguales con 320 velitas.

The scale drawing of a field in the shape of a triangle is shown below. What is the actual area, in square meters, of this feild?
Answer:
The area of the field is 70 square meters
Step-by-step explanation:
Given
See attachment for scale drawing
Required
The actual area
From the scale drawing, we have;
[tex]Base = 7[/tex]
[tex]Height = 5[/tex]
So, the area of the scale is:
[tex]Area = 0.5 * Base * Height[/tex]
[tex]Area = 0.5 * 7 * 5[/tex]
[tex]Area = 17.5[/tex] square units
Also from the attached scale,
[tex]1\ unit = 2m[/tex]
So, we have:
[tex]Area = 17.5 * (2m)^2[/tex]
[tex]Area = 17.5 * 4m^2[/tex]
[tex]Area = 70m^2[/tex]
The area of the field is 70 square meters
A grocery store collected sales data. It found that when customers buy less bread, they tend to purchase more rice. What can we conclude?
Answer:
There is a correlation between amount of bread bought and amount of rice purchased. However, there is no causation. This is because there is an increase in the amount of rice purchased with a decrease in the amount of bread bought.
Step-by-step explanation:
We see that there is a correlation between the amount of bread and the amount of rice bought .
When the bread is bought the amount of rice drops and when the amount of bread is decreased the amount of rice increases.
There is no causation meaning there is no direct affect of buying more bread or rice.Buying of rice does not directly cause the purchase of bread.
Hence there is correlation but not causation.
Correlation and causation can occur at the same time when one event causes the other.

Cos(Ф) = Adj / 5
use Pythagoras's
[tex]5^{2}[/tex] = [tex]2^{2}[/tex] +[tex]x^{2}[/tex]
25 - 4 = [tex]x^{2}[/tex]
21 = [tex]x^{2}[/tex]
[tex]\sqrt{21}[/tex] = x
Cos(Ф) = [tex]\sqrt{21}[/tex] / 5
(using the square root means the answer is exact. so leave it like that.)
Find x the missing side length of the triangle
Answer:
16.6
Step-by-step explanation:
a = 14
b = 9
c = x
a² + b² = c²
14² + 9² = x²
196 + 81 = x²
x² = 277
[tex]\sqrt{x^2} =\sqrt{277}[/tex]
x = 16.6
A rectangular plot of land has an area of 8/3 square miles and a length of 3/5 mile. What is the width of the plot of land? F.9/40 mi G.5/8 mi H.1 3/5 J.4 4/9
Answer:
Width = x mile = 4 4/9 mile
J.4 4/9
Step-by-step explanation:
Area of a rectangle = length × width
Area of the rectangular plot = 8/3 square miles
Length = 3/5 mile
Width = x mile
Area of a rectangle = length × width
8/3 = 3/5 * x
8/3 = 3/5x
x = 8/3 ÷ 3/5
Multiply 8/3 by the reciprocal of 3/5
x = 8/3 × 5/3
= (8*5) / (3*3)
x = 40/9
x = 4 4/9 mile
Width = x mile = 4 4/9 mile
