Hello!

So, using simple equation format, an equation could be:

$134.15 + $33.85 = m

Now we have to add the products.

134.15

+ 33.85

__________

168

Originally, Ronald had $168.

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

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).

A function is given:

stiks02 [169]

Answer:

Step-by-step explanation:

hello :

let f(x) = y so : x = g(y)

in expression = f(x) =3x+12

means : y = 3x +12 calculate : x

3x = y -12

x = (1/3)y - 4

the inverse is : g(x) = (1/3)x - 4

b)f(g(-2) = f(-14/3)

because: g(-2) = (1/3)(-2)-4 = -2/3-4 = -14/3

so : f(g(-2) = f(-14/3)=3(-14/3)+12 = - 2
