annual rate of retreat of the glacier
Mathematics

Let's represent the given (length, years) as (x, y)

at time 0 year, the glacier is 1000 meters

at time 15 years, the glacier retreated 255 meters and that's 1000 - 255 = 745

so we have the points (0, 1000) and (15, 745)

Using the slope formula :

m=\frac{y_2-y_1_{}}{x_2-x_1}

where m represents the average annual rate of retreat.

m=\frac{745-1000}{15-0}=\frac{-255}{15}=-17

The average annual rate of retreat of the glacier is 17 meters per year

<h3>Answer:</h3>

3)  likely

4)  1/2; equally likely

<h3>Step-by-step explanation:</h3>

3) You are being asked to translate a numerical value to a subjective statement. There are no hard-and-fast rules for this. Generally, the meanings of the terms you're asked to choose from are ...

  • impossible: probability is zero. The outcome cannot occur.
  • unlikely: chances are less than even; often, "unlikely" means a probability of 10%, 5%, 1% or lower, depending on the context.
  • equally likely: probability is near 50%
  • likely: more likely than not. Again, this depends on the context.
  • certain: probability is 1. There is no chance the outcome will not occur.

An 80% probability is greater than 50%, so might reasonably be called "likely."

___

4) a. Four of the eight numbers are even, so the probability of obtaining an even number at random is 4/8 = 1/2.

  b. A probability of 50% might reasonably be called "equally likely", as the probability the event will occur is equal to the probability it won't.

In Oregon, the mean annual rainfall in Rockaway Beach is 118.88 inches and the mean annual rainfall in Falls City is 122.28 inch
JulsSmile [24]

Answer:

Step-by-step explanation:

Based on this information, you could conclude that the annual rainfall in Falls City is generally more than that of the annual rainfall in Rockaway Beach. This is based on the information provided since the numbers given are the mean annual rainfall. Meaning that this is the average amount of rain that falls in any given year in that specific location. Since the amount provided for Falls City is a larger number then it means it gets more rainfall than Rockaway Beach on average and would therefore be the safest conclusion that can be made.
