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:
The
3
mile cab ride includes a basic charge as well as the cost for the distance covered.
For a
6
mile trip, the cost is
$
4.80
which means that :
The cost of
3
miles is
$
4.80
−
$
3.00
=
$
1.80
Therefore the cost for
1
mile is
$
1.80
÷
3
=
$
0.60
The basic fee for hiring the cab is
$
3.00
−
$
1.80
=
$
1.20
So the total cost,
c
for a trip of
d
miles will be:
c
=
0.6
d
+
1.2
Check:
If
d
=
3
c
=
0.6
(
3
)
+
1.2
=
3
If
d
=
6
c
=
0.6
(
6
)
+
1.2
=
4.8

Answer:
The sides are not equal
Step-by-step explanation:
The meaning of y in this equation is the commission I think. Sorry if I’m wrong
Answer:
One answer is (x, y) = (1, 0).
See below.
Step-by-step explanation:
If (x,y) is on the x axis then y = 0.
When y = 0.
x^4 - 15x^2 + 14 = 0
Let x^2 = z, then:
z^2 - 15z + 14 = 0
(z - 1)(z - 14) = 0
So z = 1, 14.
But z = x^2,
so x could be +/- 1 or +/-√14
and (x, y) could be (1, 0), (-1, 0), (√14, 0) and (-√14, 0).
These are the zeroes of the function.
