What is the slope of the line? A: 3 B: - 3 C: - 1 D: 1

Shtirlitz [24]

Answer:

Step-by-step explanation:

To find the slope of a line, we can use the slope formula:

$\displaystyle m=\frac{y_2-y_1}{x_2-x_1}$

So, we will need to choose two points from the graph. Any two points will work.

Let’s choose (0, -1) and (1, 2).

So, we will let (0, -1) be (x₁, y₁) and (1, 2) be (x₂, y₂). Substitute these values into the slope formula:

$\displaystyle m=\frac{2-(-1)}{1-0}$

Evaluate:

$\displaystyle m=\frac{3}{1}=3$

Therefore, the slope of the line is 3.

Hence, our answer is A.

John and Annie have two distinguishable ponds. Initially, each of the ponds contains four ducks and five geese. John first picks

Sladkaya [172]

Answer: 4/9

Step-by-step explanation:

The probability that annie picks a duck Pt= the probability of picking a duck without accounting for the added one (Po)+ probability of picking the added bird and it's a duck(Pi)

Pt = Po+Pi

Since the total number of birds in the right pond is 10 after the addition of one by john

Po= 4/10

Pi= the of john adding a duck × the probability of annie picking the added bird

Pi= 4/9 × 1/10

Pi = 4/90

Pt= 4/10 + 4/90

Pt = (36+4)/90

Pt=40/90

Pt= 4/9

(This implies that the probability of picking a duck remain the same even after the addition of one bird from the left ponds because they both have equal proportions of duck and geese i.e the initial number of duck and geese in both right and left ponds are 4 and 5 respectively)

Thanks.
