Greeley [361]3 years ago
3 0

Answer:

  1. False
  2. True
  3. Maybe
  4. False

Step-by-step explanation:

I. \[x\text{ }\text{ }y\text{ }=\text{ }y\text{ }\text{ }x\]

If \[x\text{ }=\text{ }0,\text{ }y\text{ }\ne \text{ }0\]

Then, \[\text{ }\text{ }y\text{ }=\text{ }y\text{ }\]

The equation is not true for this case.

II. \[x\text{ }=\text{ }0,\text{ }y\text{ }=\text{ }0\]

Then, the equation will be satisfied.

III. \[x\text{ }\ne \text{ }0,\text{ }y\text{ }\ne \text{ }0\]

In this case the equation may or may not satisfy the condition depending upon the value of x and y.

IV. \[x\text{ }\ne \text{ }0,\text{ }y\text{ }=\text{ }0\]

Then, \[x\text{  }=\text{ }\text{ }x\]

The equation is not true for this case.

Most major airlines allow passengers to carry two pieces of luggage (of a certain maximum size) onto the plane. However, their s
igor_vitrenko [27]

Answer:

The correct option is

d) (179.20, 212.716)

Step-by-step explanation:

We have out of a random sample of 1000, 345 carried more than a bag

Therefore in the question our X = 345 passengers carry more than a piece of luggage

n = 1000

Therefore the probability of a passenger carrying more than one luggage = 345/1000 = 0.345

The confidence interval estimator of p is given by

p'+/-z_{\alpha/2}\sqrt{\frac{p'(1-p')}{n} } where p' = 0.345 = probability of desired outcome

n = 1000 = Population size

z at 95 %   = Confidence interval estimate, the value is sought from the distribution table as z value is 1.96 at 95 % confidence level

We have  0.345+/-1.96\sqrt{\frac{0.345*(0.655)}{1000} } which gives

0.3745 or 0.3155

Which gives the range of confidential interval estimate as

212.695 to 179.224 which is equivalent to

d) (179.20, 212.716).

What is the fifth term of the sequence defined by the recursive rule f(1) = 5, f(n)=f(n-1) + 3
Oxana [17]

Answer:

f(5) = 17

Step-by-step explanation:

Using the recursive rule and f(1) = 5 , then

f(2) = f(1) + 3 = 5 + 3 = 8

f(3) = f(2) + 3 = 8 + 3 = 11

f(4) = f(3) + 3 = 11 + 3 = 14

f(5) = f(4) + 3 = 14 + 3 = 17
