Answer:
la probabilidad es 1/11
Step-by-step explanation:
Hay 4+4+4 = 12 canicas en total en la bolsa.
Pues la posibilidad de sacar una canica azul en el principio es 4/12 o 1/3.
Y luego, no reemplaces la canica, y hay 11 canicas en total.
Por eso la posibilidad de sacar otra canica azul después es 3/11.
Son eventos independientes, y tenemos que multiplicarlos para tener la respuesta.
1/3 * 3/11 = 1/11
The difference in price per passenger for a group of 16 versus a group of 10 is $26.25
<h3>What is an
equation?</h3>
An equation is an expression that shows the relationship between two or more number and variables.
From the graph:
The cost for a group of 16 friends is $2500, while for a group of 10 friends is $1300.
Cost per passenger for 16 friend = $2500 / 16 = $156.25
Cost per passenger for 10 friend = $1300 / 10 = $130
The difference in price = $156.25 - $130 = $26.25
The difference in price per passenger for a group of 16 versus a group of 10 is $26.25

Answer:
B. AAS Congruence Theorem
Step-by-step explanation:
Previous steps showed congruence of a side of the designated triangle, and two angles that do not bracket that side. In short form, you have shown congruence of ...
Angle - Angle - Side
so the AAS congruence theorem applies.
Answer:
And we can find this probability with the normal standard distirbution or excel and we got:
Step-by-step explanation:
Previous concepts
Normal distribution, is a "probability distribution that is symmetric about the mean, showing that data near the mean are more frequent in occurrence than data far from the mean".
The Z-score is "a numerical measurement used in statistics of a value's relationship to the mean (average) of a group of values, measured in terms of standard deviations from the mean".
Solution to the problem
Let X the random variable that represent the lenghts of a population, and for this case we know the distribution for X is given by:
Where
and
We are interested on this probability
And the best way to solve this problem is using the normal standard distribution and the z score given by:
If we apply this formula to our probability we got this:
And we can find this probability with the normal standard distirbution or excel and we got:
