Answer:
The margin of error is of 0.01.
Step-by-step explanation:
We have that to find our 
level, that is the subtraction of 1 by the confidence interval divided by 2. So:
Now, we have to find z in the Z-table as such z has a p-value of 
.
That is z with a pvalue of 
, so Z = 1.037.
The margin of error is of:
In which 
is the standard deviation of the population and n is the size of the sample.
Standard deviation was 0.21.
This means that 
Sample of 450:
This means that 
What is the margin of error, assuming a 70% confidence level, to the nearest hundredth?
The margin of error is of 0.01.
Answer:
6:7
Step-by-step explanation:
divide both sides by 7...
Answer:
El lugar donde la linterna, los bancos y los árboles se encuentran nuevamente está a 300 metros del punto de inicio.
Step-by-step explanation:
Los parámetros dados son;
El espacio entre las linternas = 30 metros.
El espacio entre los bancos = 20 metros.
El espacio entre los árboles = 50 metros.
Por lo tanto, tenemos, la ubicación donde la linterna, los bancos y los árboles se encuentran nuevamente, está dada por el mínimo común múltiplo de cada una de sus distancias de separación individuales como sigue;
2 divide 30 20 50 
<u>5 divide 15 10 25</u>
3 2 5
El LCM = 2 × 5 × 3 × 2 × 5 = 300
El lugar donde la linterna, los bancos y los árboles se vuelven a encontrar está a 300 metros del punto de inicio.
The additive inverse of a complex z is a complex number
so that

P,Q,R can't be 0, because their product is nonzero. Either of S and T could be 0, but the third one only works if S is 0.
