Answer:
13.13
Step-by-step explanation:
39.39 ÷ 3
13.13
There is not a lot of work
Looking at it we can tell that 3 will go into 3 one time, and 3 will go into 9 three times because:
1 x 3 = 3
3 x 3 = 9
Answer:
So about 95 percent of the observations lie between 480 and 520.
Step-by-step explanation:
The Empirical Rule states that, for a normally distributed random variable:
68% of the measures are within 1 standard deviation of the mean.
95% of the measures are within 2 standard deviations of the mean.
99.7% of the measures are within 3 standard deviations of the mean.
In this problem, we have that:
The mean is 500 and the standard deviation is 10.
About 95 percent of the observations lie between what two values?
From the Empirical Rule, this is from 500 - 2*10 = 480 to 500 + 2*10 = 520.
So about 95 percent of the observations lie between 480 and 520.
To find out the answer, we would have to try and divide all the numbers.
Answer:
Step-by-step explanation:
WeMoveU charges an hourly rate for a moving team to load and unload a truck. The charges is a different hourly rate for a team pack and unpack boxes. Use the quotes below to determine the company's hourly rates. Weekday Move: 5hours of loading and unloading services. 4 hours of packing and unpacking service. $730 total cost. Weekend Move: 4 hours of loading and unloading services. 5 hours of packing and unpacking services. $710 total cost.
Let us represent:
Hours of Loading and Unloading = X
Hours of packing = y
5hours of loading and unloading services. 4 hours of packing and unpacking service. $730 total cost.
5x + 4y = 730..... Equation 1
Weekend Move: 4 hours of loading and unloading services. 5 hours of packing and unpacking services. $710 total cost.
4x + 5y = 710.... Equation 2
Combining both Equations together
5x + 4y = 730..... Equation 1
4x + 5y = 710.... Equation 2
We solve using Elimination method
