Answer:
Step-by-step explanation:
To find the value of sin 45° we divide the opposite side length with hypotenuse
we then multiply this by
because denominator cannot be irrational
x
=

Answer:
There is sufficient evidence at 0.05 significant level to support company's claim.
Step-by-step explanation:
We have these informations from the question
n = 1400
P^ = 31% = 0.31
Alpha level = 5% = 0.05
Then we come up with the hypothesis
H0: P = 0.28
H1: P>0.28
From here we calculate the test statistic
z = p^ - p/√pq/n
P = 0.28
q = 1-0.28
= 0.72
z = 0.31-0.28/√(0.31*0.72)/1400
= 0.03/√0.0001594
= 0.03/0.012
= 2.5
Then we have a p value = 0.00621
The p value is less than significance level
0.00621<0.05
So the null hypothesis is rejected.
We conclude that There is sufficient evidence at 0.05 significant level to support company's claim.
For this case we must resolve each of the inequalities and find the solution set.
Inequality 1:

We subtract 7 from both sides of the inequality:

We divide between 12 on both sides of the inequality:

Thus, the solution is given by all values of x less than
Inequality 2:

We add 8 to both sides of the inequality:

We divide between 5 on both sides of the inequality:

Thus, the solution is given by all values of x greater than
The solution set is given by:
