Answer:If n is divisible by 10, then it is divisible by 2 or divisible by 5. ... 2. Let f : X → Y and g : Y → X be functions, and suppose that f ◦ g ... There are many different choices of (p, q) ∈ Z × Z+ which are assigned the same value by f. For example, f(1,1)=1= f(2,2). ... Since f is not an injection by part (a), it is not a bijection, either. 3 ...

Step-by-step explanation:
For the null hypothesis,
H0: p = 88
For the alternative hypothesis,
Ha: p < 88
Considering the population proportion, probability of success, p = 0.88
q = probability of failure = 1 - p
q = 1 - 0.88 = 0.12
Considering the sample,
Sample proportion, P = x/n
Where
x = number of success = 21
n = number of samples = 32
P = 21/32 = 0.66
We would determine the test statistic which is the z score
z = (P - p)/√pq/n
z = (0.66 - 0.88)/√(0.88 × 0.12)/32 = - 3.83
The corresponding p value would be determined by looking at the normal distribution table for the area below the z score. Therefore,
P value = 0.00006

Please go into more detail about the question then u will be able to help you
Each adult ticket is 6$, so if you sell adult tickets you gain dollars.
Similarly, each student ticket is 2$, so if you sell adult tickets you gain dollars.
So, the total is
Since, in your case, a=90 and s=50, the expression becomes
