Answer:
1).false 2). false 3).true 4). true
Step-by-step explanation:
1).All whole numbers are integers, so s...” That's right! All whole numbers are integers, so since 0 is a whole number, 0 is also an integer.
3).. Integers include all whole numbers and their negative counter part e.g. … -4, -3, -2, -1, 0,1, 2, 3, 4,… Where a and b are both integers. is a rational number but not an integer. 4). All integers are rational number. Since we can rewrite an integer into a fractional form by diving it by 1. For example, 4=41 4 = 4 1 . But not all rational numbers are integer.
Its 8:2/3, we can write it as
Now we can back to 12:1 - its the result
I believe it is associative because you can plug in 7 for be and still get the same answer as if you put in b for 7.
The answer is B. 9 inches because a square has 4 equal sides. The area of a square equals length times width...
So that means all 4 sides are 9 inches
9x9=81
We have to find the critical t value for 99% confidence level and sample size of 18.
Degrees of freedom = n - 1 = 17
α = 1 - 0.99 = 0.01
α/2 = 0.01/2 = 0.005
So, from the t table we have to check the value against the column 0.005 and for 17 degrees of freedom.
This value comes out to be 2.898.
So, <span>tα/2</span> = 2.898
