It’ll take 3 days to paint the house together
Daniel [21]3 years ago

Answer:

1/6 + 1/5 = 1/x,  3 days

Step-by-step explanation:

a) x days will take to paint the house together.

b) 1/6 part of the house, Noah paints for 1 day.

1/5 part of the house, Owen paints for 1 day

1/x part of the house they paint for 1 day together, and also we can write that

(1/6 + 1/5) part of the house they paint for 1 day together.

So, we can write equation

1/6 + 1/5 = 1/x

c) 1/6 + 1/5 = 1/x

30x*1/6 + 30x*1/5 = 30x*1/x

5x + 6x = 30

11x = 30

x = 30/11 ≈2.72 ≈ 3 days

In the figure, line segment VR is parallel to line segment US and m<1 = 45 degrees what is m<4?
Jobisdone [24]

The measure of ∠4 is 45°.

Solution:

Line segment VR is parallel to the line segment US.

m∠1 = 45°

∠1 and ∠4 are corresponding angles.

<em>If two lines are parallel, then the corresponding angles are congruent.</em>

m∠1 = m∠4

45° = m∠4

m∠4 = 45°

The measure of ∠4 is 45°.

The table below shows the number of shoppers at Jacob's store over a period of five months:
Olin [163]

We are given table

Month :         1     2        3         4         5

Shoppers:   50  250   1250   6250  3250

so, we have

first term =50

a_1=50

Second term =250

a_2=250

Third term =1250

a_3=1250

a_4=6250

a_5=31250

now, we can find ratios

\frac{a_2}{a_1} =\frac{a_3}{a_2}=\frac{a_4}{a_3}=\frac{a_5}{a_4}=5

we can see that all ratios are same and 5

so, this is exponential

so, option-D..........Answer

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
