Answer:

True

Step-by-step explanation:

You should always check just in case a mistake or miscalculation was made. To check, substitute the value you got for the variable into the equation and solve.

For example,

x=2

8x-2=14

Substitute 2 in for x

8(2)-2=14

16-2=14

14=14

Since this is true, we know that 2 is the correct solution.

irina [24]

Answer:

New bed dimension of bed 0.5 ft, 0.25 ft

New bed dimension of room 1.16 ft, 1.33 ft

Step-by-step explanation:

Given data:

bed dimension is given as 6 ft by 3 ft

room dimension is given as 14 ft 16 ft

according to the given information , new dimension of the room and bed will be 1/12 times of actual dimension. therefore we have

New bed dimension of bed $= \frac{1}{12} \times 6 ft, \frac{1}{12} \times 3 ft$

= 0.5 ft, 0.25 ft

New bed dimension of room $= \frac{1}{12} \times 14 ft, \frac{1}{12} \times 16 ft$

= 1.16 ft, 1.33 ft

The probability that a rental car will be stolen is. 4. if 3500 cars are rented, what is the approximate poisson probability tha

kozerog [31]

Using the Poisson distribution, there is a 0.8335 = 83.35% probability that 2 or fewer will be stolen.

<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.

The probability that a rental car will be stolen is 0.0004, hence, for 3500 cars, the mean is:

$\mu = 3500 \times 0.0004 = 1.4$

The probability that 2 or fewer cars will be stolen is:

$P(X \leq 2) = P(X = 0) + P(X = 1) + P(X = 2)$

In which:

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

$P(X = 0) = \frac{e^{-1.4}1.4^{0}}{(0)!} = 0.2466$

$P(X = 1) = \frac{e^{-1.4}1.4^{1}}{(1)!} = 0.3452$

$P(X = 2) = \frac{e^{-1.4}1.4^{2}}{(2)!} = 0.2417$

Then:

$P(X \leq 2) = P(X = 0) + P(X = 1) + P(X = 2) = 0.2466 + 0.3452 + 0.2417 = 0.8335$

0.8335 = 83.35% probability that 2 or fewer will be stolen.

Find the volume of a cylinder with a diameter of 8 inches and a height that is three times the radius round to the nearest hundr

patriot [66]

volume for cylinder = pi x r^2 x h

radius = half the diameter = 8/2 =4

height = 3 times the radius = 3*4 =12

using 3.14 for pi

volume = 3.14 x 4^2 x 12 = 602.88 cubic inches
