We can present these coordinates in tabulate form
x y
-1 0.8
0 2
1 5
2 12.5
We work the multiplicative rate of change by finding out the increase ratio
12.5 ÷ 5 = 2.5
5 ÷ 2 = 2.5
2 ÷ 0.8 = 2.5
The ratio results in the same ratio every time, which is 2.5
The multiplicative rate of change = 2.5
Answer:
50%
Step-by-step explanation:
First, draw a normal distribution plot to use for the analysis of the data. Starting at the mean in the centre. Add one standard deviation for each interval to the right, and subtract one standard deviation for each interval to the right. See attached image. According to the empirical rule, 68% of data lies within one standard deviation of the mean, 95 % of the data is within two st. dev. and 99.7% of the data is within 3 st. dev. of the mean.
From the graph it can be deducted that half of the data will lie below 50, which makes it 50%.
An easier way of determining the answer is to use the definition of a mean. A mean is the number that,when all the data is placed in ascending order, lies right in the middle of all the data.
A parallelogram is a four sided, two-dimensional shape with opposite sides that are parallel and have equal length. A triangle is a two-dimensional shape with three sides and three angles. A trapezoid is a two-dimensional shape with twoparallel sides.

Answer:
The length of the radius is 12 in
Step-by-step explanation:
To solve this problem we need to use the circumferenc formula of a circle:
c = circumference = 75in
r = radius
π = 3.14
c = 2π * r
we replace with the known values
75in = 2 * 3.14 * r
75in = 6.28 * r
75in / 6.28 = r
11.94in = r
round to the nearest inch
r = 11.94in = 12 in
The length of the radius is 12 in
