Answer:
Option c.
Step-by-step explanation:
Given information:
Mean = 50
Standard deviation = 6
Observed value = 60
We need to find the Z-score.
Formula for Z score is,
where, x is observed values,
is mean and
is standard deviation.
Substitute the given values in the above formula.
Therefore, the correct option is c.
I’m pretty sure it will be the last one f(x)=(3x+1)(2x-5).
Answer:
Well yes. So we know that our x intercepts are -2 and postive 3. If we look at the graph, we can see that when y=0, the quadratic is at both -2 and 3 for x.
Step-by-step explanation:
This might not be the full reason why this is the answer, but this is for sure part of why the factored form is correct
Sorry I cannot help more than that! :(
