What is the solution of x^2+x-6/x-7<0

Ivenika [448]

Answer:

the solution of the equation is: $(-\infty,-3)\cup (2,7)$

Step-by-step explanation:

we are given the expression as $\frac{x^2+x-6}{x-7}$

= $\frac{(x-2)(x+3)}{(x-7)}$

we will use the number line rule for inequalities(first by making the coefficients of x positive then taking the roots on the number line and depending on the sign in the equation we start taking alternate signs and depending on the inequality take the desired region)

we get $(-\infty,-3)\cup (2,7)$ .

Volume of a Rectangular Prism: V=lwh

l=50 cm
w= 30cm
h= 40 cm

Step 1: 50×30×40= 60,000

The volume of the tank is 60,000 cubic centimeters

The water reaches a height of 28 centimeters, or 2142.9 cubic centimeters per centimeter.

Step 2: 35× 2142.9= 75001.5 cubic centimeters

Step 3) 75001.5- 60,000= 15001.5 CUBIC CENTIMETERS ARE NEEDED TO FILL THE REST OF THE TANK TO A HEIGHT OF 35 CENTIMETERS

Hope this helps!

Let X equal the number of typos on a printed page with a mean of 4 typos per page.

timama [110]

Answer:

a) There is a 98.17% probability that a randomly selected page has at least one typo on it.

b) There is a 9.16% probability that a randomly selected page has at most one typo on it.

Step-by-step explanation:

Since we only have the mean, we can solve this problem by a Poisson distribution.

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 time interval.

In this problem, we have that $\mu = 4$

(a) What is the probability that a randomly selected page has at least one typo on it?

Thats is $P(X \geq 1)$ . Either a number is greater or equal than 1, or it is lesser. The sum of the probabilities must be decimal 1. So:

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

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

In which

$P(X < 1) = P(X = 0)$ .

$P(X = 0) = \frac{e^{-4}*4^{0}}{(0)!} = 0.0183$

$P(X \geq 1) = 1 - P(X < 1) = 1 - 0.0183 = 0.9817$

There is a 98.17% probability that a randomly selected page has at least one typo on it.

(b) What is the probability that a randomly selected page has at most one typo on it?

This is $P = P(X = 0) + P(X = 1)$ . So:

$P(X = 0) = \frac{e^{-4}*4^{0}}{(0)!} = 0.0183$

$P(X = 1) = \frac{e^{-4}*4^{1}}{(1)!} = 0.0733$

$P = P(X = 0) + P(X = 1) = 0.0183 + 0.0733 = 0.0916$

There is a 9.16% probability that a randomly selected page has at most one typo on it.
