The 0 in the number 402 is in the ten place. The number after it is 2. 2 is less than 5.
402 rounded to the nearest ten is 400
The 4 in the number 402 is in the hundreds place. The number after it is 0. 0 is less than 5.
402 rounded to the nearest hundred is 400
Answer:
the answers are a and d
Step-by-step explanation:
x+x+x=3x and you can't add a constant (2) to a variable(3x) so it would just be 3x+2
Me either hope you get help
Answer
:we are told that every year the temperature rises by 0.08degrees Centigrade,
So the difference between margin of error and the increase is much higher
That is
0.15-0.08=0.07
But remember Margin of error=Critical value *Standard deviation of population
And it is a quantity that measures accuracy
So the counter argument is that this is still an increase and it should be considered.

Answer:
The roots of the equation are
<h3>- 4 and 4</h3>
Step-by-step explanation:
First rewrite the expression
That's
x² - 16
16 = 4²
So we have
x² - 4² = 0
Using the identity
<h3>a² - b² = (a + b)(a - b)</h3>
Rewrite the expression
So we have
x² - 4² = 0 is
( x + 4)( x - 4) = 0
x + 4 = 0 x - 4 = 0
x = - 4 x = 4
The roots of the equation are
- 4 and 4
Hope this helps you
