Answer:
What is 20 percent of 500.? = 100.
Step-by-step explanation:
<span>Here, we first calculate the value of 't' and then go on calculating the probability that the t-value is more than calculated t-value, given the degree of freedom (d.f. = n-1).
t.calc = (77-76)/(5/sqrt(100)) = 1/(1/2) = 2
P(x > 77) = P(t > 2, d.f. =99) = 0.0241= 2.41%</span>
Answer:
where 
is an integer
Step-by-step explanation:
We are going to isolate the trig expression first.
Subtract 5 on both sides:
Divide both sides by 3:
Now since 
is even then 
.
So we have:
implies:
Multiply both sides by 2:
or
Multiply both sides by -2:
So we can say the solution is:
( is an integer)
