Answer:
Answer is in the pic
Step-by-step explanation:
A translation is just a movement of the figure so in this case you just add 3 to the x part of the coordinate.
so originally k (-2,5) m (-3,1) l (1,1)
add 3 to x so
k (1,5) m (0,1) l (4,1)

Answer:
Sample size should be atleast 617
Step-by-step explanation:
given that a 95% confidence interval for the mean of a population is to be constructed and must be accurate to within 0.3 unit.
i.e. margin of error <0.3
Std devition sample = 3.8
For 95% assuming sample size large we can use z critical value
Z critical = 1.96
we have
Sample size should be atleast 617 to get an accurate margin of error 0.3

The cost for a party here is the base fee, plus charges for any additional guests.
So we know for a 15-person party, the price is going to be $100. That's a flat (constant) cost.
We know that for each additional person, we add $12. So for
more people, the cost is $
.
Since 100 is constant here, we make that our y-intercept. Even with no additional guests, the cost is still $100.
We add to write
