Answer:

The equations whose solutions are -1/2 are:

1. 4x + 1 = 6x + 2

2. 3x + 7 = 5x + 8

Step-by-step explanation:

Using the digits 0 to 9 at most one time each, the equations whose solutions are -1/2 are:

1. 4x + 1 = 6x + 2

-2x = 1

x = -1/2

2. 3x + 7 = 5x + 8

-2x = 1

x = -1/2

Answer:

64.65% probability of at least one injury commuting to work in the next 20 years

Step-by-step explanation:

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

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

In which

x is the number of sucesses

e = 2.71828 is the Euler number

$\mu$ is the mean in the given interval.

Each day:

Bikes to work with probability 0.4.

If he bikes to work, 0.1 injuries per year.

Walks to work with probability 0.6.

If he walks to work, 0.02 injuries per year.

20 years.

$\mu = 20*(0.4*0.1 + 0.6*0.02) = 1.04$

Either he suffers no injuries, or he suffer at least one injury. The sum of the probabilities of these events is decimal 1. So

$P(X = 0) + P(X \geq 1) = 1$

We want $P(X \geq 1)$ . Then

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

In which

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

$P(X = 0) = \frac{e^{-1.04}*1.04^{0}}{(0)!} = 0.3535
$

$P(X \geq 1) = 1 - P(X = 0) = 1 - 0.3535 = 0.6465$

64.65% probability of at least one injury commuting to work in the next 20 years

Find the value of x to the nearest tenth.

nlexa [21]

Answer:

x = 14.7

Step-by-step explanation:

Using the sine rule

$\frac{a}{sin(A)} = \frac{b}{sin(B)} = \frac{c}{sin(C)}$

Substitute the given values.

$\frac{7}{sin(20)} = \frac{x}{sin(46)}$

Rearrange the equation to get x on it's own.

$\frac{7sin(46)}{sin(20)} = x$

x = 14.72246211

x = 14.7 (1dp)
