Answer:
2/7
Step-by-step explanation:
For the president position, there are 4 females from a total of 7 people.
For the vice president position, there are 3 males from 6 people left over.
So the probability is 4/7 × 3/6 = 2/7.
Answer:
gradient = 9
Step-by-step explanation:
Note that is a measure of the gradient.
Differentiate y using the power rule
(a) = na
Given
y = x² + 5x - 3, then
= 2x + 5
x = 2 : = 2(2) + 5 = 4 + 5 = 9 ← gradient
If 3 is the number missed, we want the percentage wrong
3(100)=10(x)
10x=300
Divide by 10
x=30
Answer:
12
Step-by-step explanation:
Answer:
The function is odd because it is symmetric about the origin.
Step-by-step explanation:
we know that
A function f(x) is even when
f(x)=f(-x) ----> the function is symmetry about the y-axis
A function is odd when
-f(x)=f(-x) ---> the function is symmetry about the origin
In this problem we have
f(x)=-5x
<em>Verify if the function is even</em>
For x=1 ----> f(1)=-5(1)=-5
For x=-1 ---> f(-1)=-5(-1)=5
so
f(x) is not equal to f(-x)
therefore The function is not even
<em>Verify if the function is odd</em>
we have
f(1)=-5
f(-1)=5
so
-f(1) is equal to f(-1)
-f(x)=f(-x)
therefore
The function is odd because it is symmetric about the origin.
