Answer:
if ratio is 3:5 then there are 8 parts in total
Maria receives 5/8 of 240 = 150
Alberto receives 3/8 of 240 = 90
Step-by-step explanation:
The data set that has a variation, or mean absolute deviation, similar to the data set in the given dot plot is; Option D
<h3>How to Interpret Dot Plots?</h3>
The given dot plots options are as seen in the attached brainly link.
Now, the sample dot plot shows a total of 10 dots with 3 dots on 52, 2 dots on 53, 1 dots each on 54, 55, 56, 57, 58.
Looking at the options, the only one that represents the variation, or mean absolute deviation of the given sample is Option D.

Answer:
-10
Step-by-step explanation:
1. First, let's simplify both sides of the equation.
2. To find the missing value to make the equation have infinitely many solutions, we need to make both sides of the equation equal.
3. Given that information, means that 4x - 10 has to equal 4x + (-10) because:
4. Now, with the information in #2, let's see if it's true:
-

-

- (0 = 0 means that the equation has infinitely many solutions)
Therefore, the missing number is -10.
