Answer:
x=13
Step-by-step explanation:
since they are vertical angles, they equal each other so set both angles to have them equal each other to find x
Add 12 on both sides
Subtract tax from both sides
Divide by 2 for both sides
The first statement is false and answer to second statement is no.
The mentioned information does not state that x and y are linearly related or not. If they are not related in linear way, the mean value of y would not be located at the mean of the x values.
Confidence intervals indicate the mean or population of the sample. For the confidence interval of sales of pizza stores, the similar data would be required for comparison using statistics tool. Hence, the relevant data should be sales of nearby pizza stores till now. Thus, the mentioned statement is irrelevant.

Step-by-step explanation:
You would solve by taking A=1/2(7.5+2.5)*2.5=12.5
The y-value of the vertex is 49
Queremos encontrar y resolver una ecuación algebraica para encontrar el <u>número de vecinos de la casa de Rosa.</u>
La solución es: La casa de Rosa tiene 84 vecinos.
<em>La información que se nos da es:</em>
- 2/7 de el número total de vecinos son rubios.
- La cuarta parte de estos, es decir: (1/4)*(2/7) del número total, tiene ojos azules.
- Sabemos que hay 6 vecinos con ojos azules.
Si definimos a N como el número total de vecinos, tendremos que:
(1/4)*(1/7)*N = 6
Ahora solo debemos resolver esto para N, para ello multiplicamos por 4 y por 7 en ambos lados:
4*7*(1/4)*(2/7)*N = 4*7*6
2*N = 168
Ahora dividimos por 2 ambos lados:
2*N/2 = N = 168/2 = 84
<u>La casa de Rosa tiene </u><u>84</u><u> vecinos.</u>
