Answer:
sí, así es
Step-by-step explanation:
Answer:
a) For this case we can see the distribution in the figure attached is a bell shaped graph and symmetrical around 71
b) 
We can see the value of 76 labeled in the second picture attached
c) 
And using the z score we have this using the normal standard table or excel:

d) 
We can say that about 154 and 155 students scored higher than Angelica
Step-by-step explanation:
We know that X represent the random variable scores of knowledge test and is given by:

Part a
For this case we can see the distribution in the figure attached is a bell shaped graph and symmetrical around 71
Part b
For this case the z score is given by:

And replacing we got:

We can see the value of 76 labeled in the second picture attached
Part c
We want this probability:

And using the z score we have this using the normal standard table or excel:

Part d
For this case we can find the number desired like this:

We can say that about 154 and 155 students scored higher than Angelica
In the given series, we see that the first term is 3 and
the common ratio between the succeeding terms is -3. To solve for the sum of
the first 8 terms, we use the equation,
Sum = (a1)(1 – r^n) / (1 – r)
Substituting the known terms,
Sum
= (3)(1 – (-3)^8)/(1 - -3) = -4920
<span>Thus, the answer is -4920.</span>
