Answer: The Sun and the planets formed together, 4.6 billion years ago, from a cloud of gas and dust called the solar nebula. A shock wave from a nearby supernova explosion probably initiated the collapse of the solar nebula. The Sun formed in the center, and the planets formed in a thin disk orbiting around it.
Explanation: how were the planets in the solar system formed?
The least weight of a bag in the top 5 percent of the distribution is; 246
From the complete question below, we are given;
Population mean; μ = 240
Population standard deviation; σ = 3
Z-score formula is;
z = (x' - μ)/σ
- Now, we want to find the least weight in the top 5 of the distribution and as such we will use;
1 - 0.05/2 = 0.025 as significance level
Z-score at significance level of 0.025 is 1.96
Thus;
1.96 = (x' - 240)/3
3 × 1.96 = x' - 240
x' = 240 + 5.88
x' = 245.88
Approximating to a whole number gives;
x' = 246
Complete question is;
A machine is used to fill bags with a popular brand of trail mix. The machine is calibrated so the distribution of the weights of the bags of trail mix is normal, with mean 240 grams and standard deviation 3 grams. Of the following, which is the least weight of a bag in the top 5 percent of the distribution?

Tracing a model following numbered arrows on lined paper will best provide practice for automating letter recognition in kindergartners.
<h3>Who is a Kindergartners?</h3>
These are referred to as the group of children between the ages of 4 and 6 years old who attend kindergarten as a way of preparing them for nursery school. These individuals usually have a high sense of inquisitiveness and are fast learners especially when images are used to teach them about various topics in schools or at home.
Practices for letter recognition should be done with the use of tracing the models as it serves as a very important pre-writing activity and serves as the foundation of learning which helps to ensure that adequate knowledge of certain things are achieved.

Sample Response:
Producing plastics benefits the economy by employing workers and helps the economy of every state by spending billions of dollars on shipping plastic products.
Hope this helped! :3
The graph is not found here, but a residual plot shows that the line of best fit is appropriate for data when points are well distributed on the x-axis.
<h3>What is a residual plot?</h3>
A residual plot is a diagram showing residual values on the Y-axis and an independent variable on the X-axis.
This type of plot (residual plot) is used to see the matches between observed and fitted response values.
In conclusion, the graph is not found here, but a residual plot shows that the line of best fit is appropriate for data when points are well distributed on the x-axis.
