Does soil without nitrogen decrease the weight of worms when compared to soil with nitrogen? The weights of 14 randomly selected

worms are taken, 7 in soil with nitrogen, and 7 in soil without nitrogen. The mean weights of worms in soil without nitrogen was 35.3 micrograms, while the mean weights of worms in soil with nitrogen was 36.3 micrograms. A researcher randomized the data over 100 trials, and the difference of means for each trial is shown in the dot plot below. What can the researcher conclude from this study?
a. The difference in weights is not significant because an original difference of means of –1 is very likely
b. The difference in weights is significant because an original difference of means of –1 is not very likely
c. The difference in weights is significant because an original difference of means of –1 is very likely
d. The difference in weights is not significant because an original difference of means of –1 is not very likely

What is the volume of this rectangular
Basile [38]
<h3>Given:</h3>
  • l= 5 m
  • b= 4 m
  • h= 3 m
<h3>Note that:</h3>
  • l= length
  • b= breadth
  • h= height
<h3>To find:</h3>

The volume of the given rectangular pyramid.

<h3>Solution:</h3>

\large\boxed{Formula:V=\frac{1}{3}lbh}

First, multiply the length (5), breadth (4) and height (3).

5×4×3

= 60 \: cm

Now, divide 60 by 3.

\frac{60}{3}

\large\boxed{V= 20 \: {m}^{3}}

<u>Therefore, the volume of the given rectangular pyramid is 20 cubic meters.</u>

|x - 12| = 4<br> please provide an explanation
geniusboy [140]

Answer: x = 16, x = 8

Step-by-step explanation:

|a| > 0, there are two solutions

|a| = 0, there is one solution

|a| < 0, there are no solutions

So, in this problem, we have two solutions.

In absolute value, the expression inside can be equal to itself OR its opposite.

Ex: |y| = y, |y| = -y

So, we can write two equations:

x - 12 = 4, x = 16

-x+12 = 4, x = 8

Check: |16 - 12| = |4| = 4

Check: |8 - 12| = |-4| = 4
