A student bikes 1/4 mile to school. After school, the student bikes 1/3 mile to a cousin’s house. Finally, the student bikes 7/1

gizmo_the_mogwai [7]

The miles the student biked in two weeks is 11 2/3 miles.

The distance the student bikes is given in fractions. Fractions are numbers that are made up of numerator and denominators. An examples of a fraction is 1/4. 1 is the numerator and 4 is the denominator.

In order to determine the distance biked in 2 weeks, the distance biked in a day has to be determined.

Distance biked in a day = (1/4 + 1/3 + 7/12)

14/12 = 1 2/12 = 1 1/6

Distance he would travel in 2 weeks

1 1/6 x 10

7/6 x 10 = 70 /6 = 11 2/3 miles

1. Solve the system by substitution.

zubka84 [21]

Answer:

The required solution is (0.128,13.82)

Step-by-step explanation:

Consider the provided system of equation.

$-2.5x+y=13.5$ ......(1)

$12.25x - y=-12.25$ ......(2)

We need to solve the system of equation by substitution method.

Consider the equation 1.

$-2.5x+y=13.5$

$y=13.5+2.5x$ ......(3)

Substitute the value of y in equation 2.

$12.25x - (13.5+2.5x)=-12.25$

$12.25x-13.5-2.5x=-12.25$

$9.75x-13.5=-12.25$

$9.75x=-12.25+13.5$

$9.75x=1.25$

$x\approx 0.128$

Now substitute the value of x in equation 3.

$y=13.5+2.5(0.128)$

$y\approx 13.82$

Hence, the required solution is (0.128, 13.82)

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:

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