In jungle one year monkey population increased in a ratio of 8:7 but the next year it is decreased in the ratio of 16:17.Tell ho

AleksAgata [21]

Answer:

Population of monkeys after 2 years = 3200

Step-by-step explanation:

Total number of monkeys at the start = 2975

Increase ratio of monkey population one year = $8:7$

∴ New population of monkeys after 1 year= $Total\ population \times Increase\ ratio = 2975\times \frac{8}{7} =3400$

Decrease ratio the next year = $16:17$

∴ Population of monkeys after 2 years= $New\ population \times Decrease\ ratio = 3400\times \frac{16}{17} =3200$

Find the slope for the pair of points (1,1)(4,-4)

wolverine [178]

(1, 1) and (4, -4)

Slope formula is : m = (y₂-y₁) / (x₂-x₁)

In this case :

x₁ = 1 ; x₂ = 4 ; y₁ = 1 ; y₂ = -4

Now that you know what variable counts as what, we simply just need to plug everything in.

m = (-4 - 1) / (4 - 1)

Simplify.

m = -5/3

Therefore, your slope is -5/3
