1)

a) 3/9= 0.333333333333 but you can just say 0.3
b) 4/3= 1.333333333333 but you also can say 1.33 or just 1.3

2)

a) 21/8, 21 over 8 if you solve you would get 2.625
b) 7(divide sign)4, which is also 7/4, if you solve you would get 1.75
c) 4/9 , 4 over 9 if you solve you would get 0.444444444 which is 0.4
d) 9/7, 9 over 7, if you solve it would be 1.285 which is 1.3

The three angles create a triangle. The sum of the angles of a triangle is always 180°.
Solving for x,
45° + 35° + x = 180°
x = 100°

In response to the increasing weight of airline passengers, the Federal Aviation Administration in 2003 told airlines to assume

kobusy [5.1K]

Answer:

The probability that the total weight of the passengers exceeds 4222 pounds is 0.0018

Step-by-step explanation:

The Central limit Theorem stays that for a large value of n (21 should be enough), the average distribution X has distribution approximately normal with mean equal to 182 and standard deviation equal to 30/√21 = 6.5465. Lets call W the standarization of X. W has distribution approximately N(0,1) and it is given by the formula

$W = \frac{X - \mu}{\sigma} = \frac{X - 182}{6.5465}$

In order for the total weight to exceed 4222 pounds, the average distribution should exceed 4222/21 = 201.0476.

The cummulative distribution function of W will be denoted by $\phi$ . The values of $\phi$ can be found in the attached file.

$P(X > 201.0476) = P(\frac{X-182}{6.5465} > \frac{201.0476 - 182}{6.5465}) = P(W > 2.91) = 1-\phi(2.91) = \\1-0.9982 = 0.0018$

Therefore, the probability that the total weight of the passengers exceeds 4222 pounds is 0.0018.
