Answer:
2.0015305e+15 is the answer
Answer:
x = j – f - 2
Explanation:
(x + f) + 2 = j Remove parentheses
x + f + 2 = j Subtract f from each side
x + 2 = j – f Subtract 2 from each side
x = j – f - 2
Answer:
Step-by-step explanation:
Because if you put together two trapezoids, one in a reversed position, you get a paralelogram. There the side of the parallelogram is the sum of the trapezoid bases, as in the picture.
The are of paralelogram is: A=(b+B)×h
For trapezoid, half of parallelogram:
A1=A/2=(b+B)×h/2
Answer:
1. A) the data is more spread out
2. C) the data is less spread out
Step-by-step explanation:
1) Standard Deviation is a measure of dispersion, denotes the spread of data around measure of central tendency (usually arithematic mean).
A data set with higher standard deviation implies A) Data is more spread out or scattered, & vice versa less spread for less standard deviation.
2) Interquartile range is also a measure of dispersion, denoting difference between Q1 (25th percentile) & Q3 (75th percentile).
A data set with smaller interquartile range implies C) Data is less spread out, & vice versa more spread for higher interquartile range.
