natka813 [3]

Answer: The required probability is \dfrac{8}{125}

Step-by-step explanation:

Since we have given that

Number of spruce tree = 20

Number of maple tree = 50

Total trees = 70

We need to find the experimental probability that the next tree Colleen to get a spruce tree.

So, the probability would be :

(\dfrac{20}{50})^3=(\dfrac{2}{5})^3=\dfrac{8}{125}

Hence, the required probability is \dfrac{8}{125}

Solve the equation <br> -10 + 3x + 5x = -56 ? ??
Xelga [282]
Add like terms on the same side:
-10 + 8x = -56
Add ten to both sides
-10 + 8x + 10 = -56 +10
Simplify:
8x = -46
Divide both side by 8
8x/8 = -46/8
Simplify
x = - 5.75
The answer is x = -5.75
(The answer can also be written as -23/4 or -5 3/4)

PLZZZZ HELP The Lakeview city council is considering two different plans to help reduce the amount of pollution in the city. Pla
sdas [7]
1. The two equations follow the slope-intercept form which y=mx + b. They have the same y-intercept which is equal to 900.

2. Suppose x= 10
    Plan Alpha: y=-7x+900=-7(10)+900=830
    Plan Foxtrot: y = -17x+900 = -17(10)+900=730
    
    Between the 2 plans, the lower value is 730. Plan Foxtrot is better for reduction of pollution.

3. The city council should choose Plan Foxtrot because the reduction of pollution is much greater. Their goal would be reached faster if they go with faster reduction of pollution.
