So the scale is 3/4 cm for every 6 meters
So if you have 8 cm, we want to find the dimension of the actual wall
convert cm to meters
0.75 cm = 0.0075 meters
8 cm = 0.08 meters
![\frac{0.0075}{6} = \frac{0.08}{x}](https://tex.z-dn.net/?f=%5Cfrac%7B0.0075%7D%7B6%7D%20%3D%20%5Cfrac%7B0.08%7D%7Bx%7D)
Cross Multiply
0.0075x = 0.48
x = 64 meters
Answer:
0.018133
Step-by-step explanation:
Given that customers arrive randomly and independently at a service window, and the time between arrivals has an exponential distribution with a mean of 12 minutes.
Let X equal the number of arrivals per hour.
X is having average as reciprocal of 12 minutes
i.e. in one hour on an average expected customers to arrive is 60/12 =5
X being reciprocal of exponential is Poisson with parameter = 5
Probability that 10 customers arrive in one hour
=P(X=10)
=0.018133
Answer:
D
Step-by-step explanation:
for 20 pounds of grass seed, we need 356 pounds of fertilizer
20 pounds of grass seed : 356 pounds of fertilizer
divide both sides by 20 to get 1 pound of grass seed on one side, as we want to figure out the corresponding amount of fertilizer for 1 pound of grass seed
20 pounds of grass seed/20 : 356 pounds of fertilizer/20
1 pound of grass seed: 17.8 pounds of fertilizer
Answer:
3
Step-by-step explanation:
You have a 1 in 6 chance to roll a two. This means that every six times you roll a dice 1 of those should be a two (Obviously in the real world this wouldn't happen)
You roll the dice 18 TIMES and your chances are 1 in 6 so you take
![18 \times \frac{1}{6}](https://tex.z-dn.net/?f=18%20%5Ctimes%20%20%5Cfrac%7B1%7D%7B6%7D%20)
