Write an expression for the perimeter of the triangle shown in the picture

Which of the following is the solution to the inequality -2x-4 ≤ 11

Art [367]

Answer:

$x\geq -\frac{15}{2}$

Step-by-step explanation:

add 4 on both sides

leaves you with 15 on the right side

you then divide by negative 2

since you divide by a negative you have to switch the sign

19) Amount of oil in = amount of oil in final product

.025(x) + .09(40-x) = .055(40) (x = 2.5% amt 40 - x = 9% amt)

x = 21.54 L of 2.5 % then 9% = 18.46 L

An old house in Pomona, CA is inhabited by a variety of ghosts. Ghost appearances occur in the house according to a Poisson proc

shutvik [7]

Answer:

The probability is 0.503

Step-by-step explanation:

If the ghost appearances occur in the house according to a Poisson process with mean m, the time between appearances follows a exponential distribution with mean 1/m. so, the probability that the next ghost appearance happens before x hours is equal to:

$P(X\leq x)=1-e^{-xm}$

Then, replacing m by 1.4 ghosts per hour we get:

$P(X\leq x)=1-e^{-1.4x}$

Additionally, The exponential distribution have a memoryless property, so if it is now 1:00 p.m. and we want the probability that ghost appear before 1:30 p.m., we need to find the difference in hours from 1:00 p.m and 1:30 p.m. no matter that the last ghost appearance was at 12:35 p.m.

Therefore, there are 0.5 hours between 1:00 p.m. and 1:30 p.m, so the probability that the 7th ghost will appear before 1:30 p.m is calculated as:

$P(x\leq 0.5)=1-e^{-1.4*0.5} =0.503$

The Table Shows a proportional relationship between x and y for each Value of x and y match it to the correct unit rate y/x in i

Elden [556K]

The correct proportions are given as follows:

x = 3, y = 27: 9/1.

x = 9, y = 81: 9/1.

x = 21, y = 126: 6/1.

x = 14, y = 84: 6/1.

x = 12, y = 36: 3/1.

x = 15, y = 45: 3/1.

<h3>What is a proportion?</h3>

A proportion is a fraction of a total amount, and the measures are related using a rule of three.

The proportions for this problem are given dividing y by x, hence:

x = 3, y = 27: 27/3 = 9, hence 9/1 has to be marked.

x = 9, y = 81: 81/9 = 9, hence 9/1 has to be marked.

x = 21, y = 126: 126/6 = 6, hence 6/1 has to be marked.

x = 14, y = 84: 84/14 = 6, hence 6/1 has to be marked.

x = 12, y = 36: 36/12 = 3, hence 3/1 has to be marked.

x = 15, y = 45: 45/15 = 3, hence 3/1 has to be marked.
