1. A right triangle has a hypotenuse of length 10 yd and one leg of length 2 yd.
Aleonysh [2.5K]

Question 1.

The Pythagoras Theorem states that the square of the hypotenuse is equal to the sum of the square of the two legs.

h^2=l_1^2+l_2^2

From the question, the hypotenuse is h=10 yd and one of the legs is 2yd.

This implies that,

10^2=l_1^2+ {2}^{2}

Evaluate the exponents

100=l_1^2+ 4

Subbtract 4 from each side

100 - 4=l_1^2

l_1^2 = 96

l_1=  \sqrt{96}

l_1 =  \sqrt{16 \times 6}

l_1 =  4\sqrt{6}

The correct answer is C

Question 2

We want to solve

{e}^{4x}  = 11

using inverse functions.

The inverse of an exponential function is a logarithmic function.

We take natural log of both sides to get;

ln({e}^{4x})   =  \ln(11)

Recall that

\ln( {a}^{n} )  = n  \ln(a)

This means

4x \ln({e})   =  \ln(11)

Logarithm of the base is 1

4x (1)   =  \ln(11)

4x   =  \ln(11)

Divide both sides by 4

x=  \frac{ \ln(11)}{4} \\x=0.5995\\ x = 0.6

45% is 0.45. To switch into a fraction you do 45 over 100, simplified is 9/20.

Using the Poisson distribution, the probabilities are given as follows:

A. 0.0888 = 8.88%.

B. 0.1354 = 13.54%.

C. 0.8646 = 86.46%.

<h3>What is the Poisson distribution?</h3>

In a Poisson distribution, the probability that X represents the number of successes of a random variable is given by:

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

The parameters are:

  • x is the number of successes
  • e = 2.71828 is the Euler number
  • \mu is the mean in the given interval.

Item a:

10 hours, 2 calls per hour, hence the mean is given by:

\mu = 2 \times 10 = 20.

The probability is P(X = 20), hence:

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

P(X = 20) = \frac{e^{-20}20^{20}}{(20)!} = 0.0888

Item b:

1 hour, hence the mean is given by:

\mu = 2

The probability is P(X = 0), hence:

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

P(X = 0) = \frac{e^{-2}2^{0}}{(0)!} = 0.1354

Item c:

The probability is:

P(X \geq 1) = 1 - P(X = 0) = 1 - 0.1354 = 0.8646
