They slow down, because condensation causes them to bond together, forming a liquid.

2. $40,000
Explanation:
The sum of the two numbers is equal to 70.
- Let the first number be x.
- Let the second number be y.
In this exercise, you're required to find two numbers by translating the word problem into an algebraic expression and then solving for the unknown variables (x and y).
Translating the word problem into an algebraic expression, we have;
Two numbers differ by 8:
....equation 1.
The product of the two numbers is 713:
....equation 2.
To calculate the sum of the two numbers:
First of all, we would solve for each of the unknown variables (x and y).
From eqn. 1, we have:
....equation 3.
Substituting eqn. 3 into eqn. 2, we have:
Solving the quadratic equation by factorization, we have:
y = -23 or 31.
For the value of x, when y = 31:
x = 39
Now, we can calculate the sum of the two numbers:

The option that is not a correct description of the distribution of the amount spent by the 50 shoppers at the grocery store is D) The distribution is uniform, with all values equally likely.
<h3>What is a stemplot?</h3>
A stemplot is a graphical way of displaying numerical data that uses place value to group the data. The leftmost digits of the data values form the stem, and the rightmost digits form the leaf.
The distribution is symmetric, because the left and right halves of the stemplot are roughly mirror images of each other. The mean and median are both about $25, because the middle value of the data is $25, and the sum of the data values divided by the number of data values is also $25. The distribution is not skewed to the right or left, because there are no long tails or outliers on either side of the peak.

Complete question
The stemplot displays data on the amount spent by 50 shoppers at a grocery store. Note that the values have been rounded to the nearest dollar.
Which of the following is not a correct description of the distribution of the amount spent by the 50 shoppers at the grocery store?
A) The distribution is symmetric, with a mean and median of about $25. B) The distribution is skewed to the right, with a mean of about $30 and a median of about $25. C) The distribution is skewed to the left, with a mean of about $20 and a median of about $25. D) The distribution is uniform, with all values equally likely.
