Answer 1

Answer:

Step-by-step explanation:

Okay, so first you take 3 × 10∧-6m back to its decimal form, giving you 0.000003. Also, take 4.5×10∧-4m back to its decimal form giving you 0.00045. You then divide 0.00045 by 0.000003 giving you 6.66666 but we then take it to 6.67 × 10∧2 which is the answer.

|_____________ l /

11m. 2m

( 13m).

Area of rectangle= Length × Width

= 11m × 3m

= 33m²

Area of triangle= ½ × base × height

To find the height= 13m - 11m = 2m

= ½ × 3 × 2

= ½ × 6

= 3m²

Area of the polygon= 33m² + 3m² = 36m²

36 is the area of that

If the probability of no rain tomorrow is 30%, what is the probability that it will rain tomorrow? Express your answer as a percent.

Answers

Answer:

70%

Step-by-step explanation:

Since the probability of no rain tomorrow is 30%, that means 30% of the probability is taken up by the chance of no rain.

Since the total probability always adds up to 100%, that means the remaining 70% of the probability must be for rain.'

So the probability that it will rain tomorrow is 70%.

You can verify this with a probability tree diagram:

Total Probability = 100%

No Rain - 30%

▼

More Likely event

▲

Rain - 70%

Since the chance of no rain is 30%, that leaves 70% for the chance of rain.

The probability that it will rain tomorrow is 70%.

What is probability?

Probability is a measure of the likelihood of an event to occur. Many events cannot be predicted with total certainty. We can predict only the chance of an event to occur i.e., how likely they are going to happen, using it. Probability can range from 0 to 1, where 0 means the event to be an impossible one and 1 indicates a certain event.

Given the problem, we need to find the probability that it will rain tomorrow.

Since, the probability of no rain tomorrow is 30%, the probability that it will rain tomorrow is 100% - 30% = 70%.

Hence, the probability that it will rain tomorrow is 70%.
