To do this, we simply consider the inequalities that bound the values of x.
The inequalities are:
and
Combine the first two inequalities:
and
For the inequality to be true, we must have:
In interval notation, the inequality is:
Answer:
Step-by-step explanation:
If this is
then you distribute the 3 to both terms inside the parenthesis (the 2 and the c^-5). 2 cubed is 8. The rule for the power to power is that you multiply the powers together to get -15. So the final simplification is
Answer: a) -0.2252, b) 0.8219
Step-by-step explanation:
Since we have given that
Sample size n = 100
Probability that candies are blue = p= 0.26
Probability that company claims that it is blue candy = P = 0.27
So, Q = 1-P= 1-0.27 = 0.73
So, Null hypothesis :
Alternate hypothesis :
So, the test statistic would be
Since α = 0.05
So, critical value of z = 1.96
p-value = P(Z>Z(calculated)
Using the excel function , we get that
Hence, a) -0.2252, b) 0.8219
