Answer:
18%
Step-by-step explanation:
There are 64 students with brown eyes and black hair, and 9 students with blue eyes and black hair. A total of 303 students were surveyed, so to find the percentage you would put the number of students with that trait over the total number of students surveyed. 64/303 = 21.1221%, and 9/303 = 2.9702%. 21.1221 - 2.9702 = 18.1519. When you round that to the nearest whole number, you get 18%. Therefore, the percentage of the sample population with brown eyes and black hair is larger than the percentage of the sample population with blue eyes and black hair by 18%.
Answer:78/100or39/50
Step-by-step explanation:
Answer:
y-6 = (7/6)(x-2)
---------------------------------------------------
Explanation:
The median DT goes from point D, which is given, to point T which we have to find. The point T is the midpoint of segment EF.
Use the midpoint formula to find the midpoint. Add up the x coordinates of E and F to get
-1+5 = 4
Then divide that by 2
4/2 = 2
The x coordinate of point T is x = 2
Repeat for the y coordinates
8+4 = 12
12/2 = 6
The y coordinate of point T is y = 6
So the point T is (x,y) = (2,6)
---------
We know point D is (-4,-1)
We just found point T to be (2,6)
Using the slope formula, the slope is..
m = (y2-y1)/(x2-x1)
m = (6-(-1))/(2-(-4))
m = (6+1)/(2+4)
m = 7/6
The slope is m = 7/6
Use either the coordinates of D or T. I'll use point T. So (x1,y1) = (2,6) meaning x1 = 2 and y1 = 6
We'll plug m = 7/6, x1 = 2 and y1 = 6 into the point slope equation
y-y1 = m(x-x1)
y-6 = (7/6)(x-2)
which is the final answer
168 is the answer no explanation sorry but the answer is 168
