Answer:
P(1,-1)
Step-by-step explanation:
x=5 - 4 (left towards negative x) = 1
y= -4 + 3 (up towards positive y) = -1
Answer:
b. 0.055
Step-by-step explanation:
The point estimate of the proportion of people who wear hearing aids is
The number of people in the sample who wear hearing aids divided by the total number of people in the sample.
In this problem, we have that:
Sample of 855.
47 people in the sample had hearing aids.
47/855 = 0.0549
Rounding up
0.055
So the correct answer is:
b. 0.055
The teacher bought 195 tickets because i just did 5460 divided by 28
Answer:
The value of k is 4.
Step-by-step explanation:
To find the missing coordinate, we can use the slope equation and plug in all known values.
m(slope) = (y2 - y1)/(x2 - x1)
-1 = (k - 0)/(-2 - 2)
-1 = k/-4
Now we can solve using cross multiplication.
-1 = k/-4
k*1 = -1*-4
k = 4
