Answer:
-2, 3
Step-by-step explanation:
We are given the following inequality:
Solving it, we have that its solution is:
So values of x of 5 and lower are counterexamples to this, which means that -2 and 3 are correct options to this question.
Answer:
The lower class boundary for the first class is 140.
Step-by-step explanation:
The variable of interest is the length of the fish from the North Atlantic. This variable is quantitative continuous.
These variables can assume an infinite number of values within its range of definition, so the data are classified in classes.
These classes are mutually exclusive, independent, exhaustive, the width of the classes should be the same.
The number of classes used is determined by the researcher, but it should not be too small or too large, and within the range of the variable. When you decide on the number of classes, you can determine their width by dividing the sample size by the number of classes. The next step after getting the class width is to determine the class intervals, starting with the least observation you add the calculated width to get each class-bound.
The interval opens with the lower class boundary and closes with the upper-class boundary.
In this example, the lower class boundary for the first class is 140.
Yes, triangle ZHY and JHI are similar triangles because if you multiply each side on Triangle ZHY by 2, they equal the sides of the Triangle from IHJ.
For example, ZH x 2= JH , YZ x 2= IJ
Width = x
Length = 3x
Perimeter = x + x + 3x + 3x = 8x
He walked 3 rounds
3 x 8x = 24x
Total distance walked = 5280 feet
24x = 5280
x = 220
Shortest side is 220 feet
Answer:
90/360 x 3.14 x 
. (put into calculator)
Step-by-step explanation:
This is a sector of a circle we can see that there is a right angle (90 degrees) so we can say there is 90/360 of a circle.
The formula for the area of a circle is pi times radius squared.
We can use this but also need to use 90/360.
We can say the area of the shape is 90/360 x 3.14 x .
