Answer:

Step-by-step explanation:

Q1 It is given that CD||EF

Thus m angle C +m angle F=180°

m angle C= 180°-79°

m angle C=101°

Similarly m angle E=46°

Note same concept must be applied to rest of the questions

Crank

Answer:

the answer is c: s=40(1.1)^m, s=20(1.15)^m

Step-by-step explanation:

in option A, (0.10) and (0.15) make it exponential decay rather than exponential growth like it's supposed to be.

In option B, the rate of growth is supposed to be on the exponent, not the sales themselves in the equation

option c is correct I just finished the test

option d has the same mistake as a and b combined

If the angles of a traingle are in the ratio 2:3:4 , Find Them

DedPeter [7]

Answer:

40°, 60°, and 80°

Step-by-step explanation:

We know that the sum of the angles of a triangle is equal to 180°.

We can use this equation to solve for these angles:

180 = 2x + 3x + 4x

180 = 9x

20 = x

Then substitute the solution in for x to solve for the angles:

2(20) = 40°

3(20) = 60°

4(20) = 80°

Therefore, the angles are 40°, 60°, and 80°.

he time between arrivals of small aircraft at a county airport is exponentially distributed with a mean of one hour. Round the a

Eva8 [605]

Answer:

The answer is below

Step-by-step explanation:

The time between arrivals of small aircraft at a county airport is exponentially distributed with a mean of one hour. Round the answers to 3 decimal places.

(a) What is the probability that more than three aircraft arrive within an hour?

(b) If 30 separate one-hour intervals are chosen, what Is the probability that no interval contains more than three arrivals?

(c) Determine the length of an interval of time (in hours) such that the probability that no arrivals occur during the interval is 0.1.

Solution:

a) A poisson distribution is given by the formula:

$P(X=x)=\frac{e^{-\lambda }\lambda^x}{x!}$

λ = 1 hour

Therefore:

P(X > 3) = 1 - P(X < 3) = 1 - [P(X = 0) + P(X = 1) + P(X = 2) + P(x = 3)]

$P(X=0)=\frac{e^{-1}*1^0}{0!}=0.3679$

$P(X=1)=\frac{e^{-1}*1^1}{1!}=0.3679$

$P(X=2)=\frac{e^{-1}*1^2}{2!}=0.1839$

$P(X=3)=\frac{e^{-1}*1^3}{3!}=0.0613$

P(X > 3) = 1 - [0.3679+0.3679 + 0.1839 + 0.0613] = 0.019

b) Assuming 30 1 hour intervals, hence:

$P(X \leq 3)^{30}=[1-P(X\geq 30)]^{30}=(1-0.019)^{30}=0.5624$

c) mean = 1 hour

mean = 1 / λ

1 = 1 / λ

λ = 1

The cumulative distribution function of a continuous variable is:

$F(x)=1-e^{-\lambda x}$

$0.1=1-F(x)\\\\0.1=1-(1-e^{- x})\\\\0.1=e^{- x}\\\\-x=ln(0.1)\\\\-x = -2.3\\\\x=2.3\ hours$
