Graph A shows a positive linear association between x and y.
If the angles are 90,45,45 so the sides except hypotenuse are congruent
and the hypotenuse is equal to :
the answer is 12
hope this helps
Answer:
a) f(-1) = 1
b) f(0) = 6
c) f(2) = 8
Step-by-step explanation:
If x is lesser than 0, we have that:
f(x) = 4x + 5
Otherwhise
f(x) = x + 6
(a) f(-1)
Here x = -1.
-1 is lesser than 0
Then
f(x) = 4x + 5
f(-1) = 4*(-1) + 5 = -4 + 5 = 1
(b) f(0)
Here x = 0
When x equals 0
f(x) = x + 6
Then
f(0) = 0 + 6 = 6
(c) f(2)
Here x = 2
When x = 2
f(x) = x + 6
Then
f(2) = 2 + 6 = 8
Answer:
for the first card selected, just multiply the number of cards of that kind over the total amount (30) by the new number of cards of that kind over the new total amount (29)
sample space is 10+6+9+5=30
7. 10/30*9/29=0.103
8. 6/30*5/29
9. 9/30*6/29
10. 5/30*9/29
11. 21/30*20/29
12. 19/30*18/29
So we would want to isolate x. Start by multiplying both sides by -3. Since we are multiplying negative number, we flip the sign.
So that would be x ≥12. That means x should be greater than or equal to 12.
So now it's easy to answer.
C, D, E would be the answer.
