Considering that the p-value associated for a r<em>ight-tailed test with z = 2.115</em> is of 0.0172, it is found that it is significant at the 5% level, but not at the 1% level.
<h3>When a measure is significant?</h3>
- If p-value > significance level, the measure is not significant.
- If p-value < significance level, the measure is significant.
Using a z-distribution calculator, it is found that the p-value associated for a r<em>ight-tailed test with z = 2.115</em> is of 0.0172, hence, this is significant at the 5% level, but not at the 1% level.

So for the first one it is (x-3)(x+3) this is because it is a difference of squares so you square root the 9 and the minus you do both +and - in order to keep up the -9
The zeros are:x=3 and x=-3 ( this is because you change the sign in the bracket
the others should be pretty simple to do for number 2 its a complex
the third is a simple trinomial
and fourth is simple trinomial as well
Answer:
1,75 kg
Explanation:
1 kg = 1000 g
2.5 kg = 2.5 × 1000 g = 2500 g
2500 g - 750 g = 1750 g
1750 g = 1750 ÷ 1000 kg = 1.75 kg
Answer: Undefined
Step-by-step explanation:
In geometry there are three undefined terms that we use to define other terms:
- Point → In geometry a point has a location but no dimension.
- Plane → A plane extends is a 2-dimensional surface that extends infinitely on both sides.
- Line → A line is a one-dimensional undefined figure that extends infinitely in both the directions. It has length but has no width.
Hence, the correct option is "Undefined".
