Stop and save because you save your money and get more apples
Answer:

Step-by-step explanation:
Total Students = 28
Brown Hair = 22
NOT Brown Hair = 28 - 22 = 6
The probability of an event is the number of that event divided by total number.
So, let denote probability of without brown hair be P(NOT BROWN). So, we can say:
P(NOT BROWN) = 6/28
Reducing, we get:
P(NOT BROWN) = 3/14
Answer:
0.8r
Step-by-step explanation:
r - 0.2r
= 1r - 0.2r ← factor out r from each term
= r(1 - 0.2)
= r × 0.8
= 0.8r
Answer:
-46
Step-by-step explanation:
4-2(25)=
4-50=
-46
Let the required equation be y = mx + c; where y = 1, m = f'(0), x = 0
f(a) = sec(a)
f'(a) = sec(a)tan(a)
f'(0) = sec(0)tan(0) = 0
y = mx + c
1 = 0(0) + c
c = 1
Therefore, required equation is
y = 1.
