Okay well if u lose 1.1% every year means you are left with a 'REMAINING' percentage of 98.9% which is 0.989

Answer: She should use 0.989 as the common ratio.

Step-by-step explanation:

Given: A conservationist determines that a particular beach is eroding at a rate of 1.1% each year.

i.e. the rate of decay k= 1.1%=0.011

When writing an explicit formula to represent the amount of beach remaining each year, the common ratio 'r' for decay rate k is written as :

r=(1-k)=(1-0.01)=0.989

Hence, she should use 0.989 as the common ratio.

A city in the Pacific Northwest recorded its highest temperature at 91 degrees F and its lowest temperature at 12 degrees F for
docker41 [41]

Answer:

(A)12-19

Step-by-step explanation:

To construct a frequency distribution, we follow the steps below.

1. Find the largest and smallest values.

91 and 12 respectively

Compute the Range = Maximum - Minimum=91-12=79

2. Determine the number of classes desired.

In this case, we desire 10 classes

3. Next, we find the class width by dividing the range by the number of classes and rounding up.

79÷10 = 7.9

Rounded Up, Class Width=8

4. Pick a suitable starting point less than or equal to the minimum value.

Since our minimum value is 12, we pick a class starting with 12 and give a class width of 8.

Therefore the upper and lower limits of the first class is given as:

12-19.
