Answer: 3y+8
Step-by-step explanation:
Peachy Orchard Developers are preparing land to create a large subdivision of single-family homes. They have already built 15 houses on the site. Peachy Orchard plans to build six new homes every month. Write a sequence for the number of houses built, then write an equation for the sequence. Fully describe a graph of this sequence. The sequence is 21, 27, 33, 39, .... Note that sequences usually begin with the first term, where the number of months n =1.
Answer:
Step-by-step explanation:
Restaurant A data in ascending order : 67 68 72 89 96 97 120 124
Restaurant B data in ascending order : 49 56 76 78 95 98 115 126
<em>Restaurant A</em>
- Mean =
= 91.625 - Median = Since there are even number of observations so,
=
=
= 92.5
- Mid range =
=
= 28.5 - Range = Highest value - Lowest value = 124 - 67 = 57
- Variance =
,where Xi are sample values and
is mean
Solving above equation we get, variance = 493.982
- Standard Deviation =
= 22.226
<em>Restaurant B</em>
- Mean =
= 74.375
- Median = Since there are even number of observations so,
=
=
= 86.5
- Mid Range =
=
= 38.5
- Range = Highest value - Lowest value = 126 - 49 = 77
- Variance =
,where Xi are sample values and
is mean
= 727.982
- Standard Deviation =
= 26.981
Now comparing the results of two restaurants we conclude that:
- Restaurant A on an average takes more time for drive-through service than Restaurant B.
- Median time for Restaurant A is also more than Restaurant B.
- Restaurant B has more variation in time taken for drive through service as the variance & standard deviation of Restaurant B is more than A.
- There is more spread in the time data for Restaurant B as it has more range than A.
1) I’m pretty sure for this one the answer is X = 1, -1 but that’s not an option. So I’d double check with your teacher so make sure there is no typo.
