How do I solve a probability question?

1 answer:

3 0

Solving probability is finding the likely hood of an event. So for example if you have 4 red circles and 3 yellow and you were trying to find the probability of picking yellow, you would add all of the blocks together. After you would put the problem into a fraction; with 3(the amount we are given) on top and 7(the total) on the bottom. I hope that helps but if it’s a more specific question, let me know!

Josh is putting up a fence around a garden that is next to a wall. He only has 54 feet of fence and the length of the garden mus

vova2212 [387]

Answer:

Length = 12 feet

Width = 30 feet

Step-by-step explanation:

Let l be the length of the garden and let w be the width:

We have system of equations

2w + l = 54

l = 2w + 6

We substitute 2w + 6 for l

2w + 2w + 6 = 54

4w + 6 = 54

4w = 54 - 6

4w = 48

w = 48/4

w = 12 feet

Width(w) = 12 feet

We find the Length

l = 2w + 6

l = 2(12) + 6

l = 24 + 6

I = 30 feet

Answer:

B) Experiment: you imposed a treatment (new fertilizer on some plants, old on others) to determine its effect.

Step-by-step explanation:

In this situation, the fertilizer developer wants to evaluate a hypothesis, not just observe, by subjecting plants to two different treatments (new and old fertilizer) in order to determine which treatment provides a more desirable effect (more plant growth).

This process configures an experiment.
