2 2/3 Divided by 4 would be 2/3 because 2 2/3 equals 8/3 and 2 goes into 8 4 times.

First we change our mixed number to an improper fraction...

2 2/3 ÷ 4 =
8/3 ÷ 4

To divide fractions we multiply the reciprocal of the divisor..

8/3 ÷ 4/1 =
8/3 × 1/4 = 8/12 = 2/3

Fittoniya [83]

Answer:

$-7y$

Step-by-step explanation:

Our equation is:

$\left(1x-5y\right)-1\left(x+2y\right)$

First we dritribute

Now we have, $x-5y-x-2y$

$Combine$ light terms

and we get $-7y$

nirvana33 [79]

1) with the the following equation you can find the slope having two points

m = Y2-Y1/X2-X1 , A(-3,0) B(3,2)

m= 2-(0) / 3-(-3) m = 2/6 = 1/3, the correct option is C

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:

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