Think of the decimals in the probability column as percentage. So Micheal has a 30% chance of eating the next fry, Lidia would have a 10% chance, so on and so forth.
The percentage will always go up to 100%.
You're given the other people's percentages, but not Ronald.

Domarina is making bracelets. she needs 62 cm of gold wire for each bracelet. A roll of wire has 3.10 meters. How many bracelets can she make from one roll of wire.
Answer:
5
Step-by-step explanation:
To figure this out you first need to find how many centimeters 3.10 meters is worth. 3.10m=310cm. Then, since each bracelet needs 62 cm, you just do 310/62. 310/62=5 So you can make 5 bracelets with one roll of wire.

Angel decides to exceed the walking challenge goal. Describe two ways you might adjust the equation or inequality in Part A to represent Angel’s decision to exceed the goal. Give an example and explain.
Answer:
Step-by-step explanation:
The original distance that Angel wanted to walk will be represented as A
Since we don't know the additional distance Angel walked it'll be represented as B
A= the amount of distance Angel wanted to walk
B= the amount of distance Angel wanted to walk past his/her challenge goal
C= the amount of distance Angel walked originally from to past her/his challenge goal
A+B=C
Example:
I decide to work for A hours today as a challenge. Within this time I'm working I decided to extend my goal another B hours.

Which term can be used in the blank of [tex]36x^3-22x^2 -[/tex] _____ so that the greatest common factor of the resulting polynomial is 2x? Select TWO options:
A: 2
B: 4xy
C: 12x
D: 24
E: 44y
Answer:
The missing term is 4x
The missing term is 16x
Step-by-step explanation:
* Lets explain how to solve the problem
- The polynomial is 36x³ - 22x² - ..............
- We need to find the missing term such that the greatest common
factor of the resulting polynomial is 2x
The greatest power of x is 3, and there is another term with x²,
then the missing term must have x to have a greatest common
factor of the variable = x
The coefficients of the given terms are 36 and 22 , the greatest
common factor of them is 2 so we must to chose the coefficient
of the missing term with a factor 2
# Option 1:
the missing term is 4x
36x³ - 22x² - 4x = 2x(18x² - 11x - 2)
* The missing term is 4x
# Option 2:
the missing term is 16x
36x³ - 22x² - 16x = 2x(18x² - 11x - 8)
* The missing term is 16x

3) fill in the blanks:
Alita is __ years old
Jiro is __ years old
Erik is __ years old

thanks!! :)
Answer:
dudee 4 months ago you asked this question I feel bad.
Step-by-step explanation:
1) The Equation to represent the situation is
x+ x/3 + x/3-4 + 2( x/3 - 4)= 72
2) Alita is 16 years old
Jiro is 8 years oldErik is 12 years oldDawn is 36 years oldWhat is Algebra?A branch of mathematics known as algebra deals with symbols and the mathematical operations performed on them.
Variables are the name given to these symbols because they lack set values.
In order to determine the values, these symbols are also subjected to various addition, subtraction, multiplication, and division arithmetic operations.
Given:
let the age of Dawn be x.
then age of Erik = x/3
Now, Jiro is 4 years younger then Erik.
Jiro's age = x/3 - 4
and, Alita is 2 times as old as Jiro.
So, Alita's age be = 2( x/3 - 4)
As, The sum of all their ages is 72.
x+ x/3 + x/3-4 + 2( x/3 - 4)= 72
x+ x/3 + x/3-4 + 2x/3 - 8 = 72
7x/3 - 12 = 72
7x/3 = 84
x = 36
Thus,
Alita is 16 years oldJiro is 8 years oldErik is 12 years oldDawn is 36 years oldLearn more about Algebra here:

Rhonda kept track of the cats at a shelter where she volunteers. She measured how many times per day each cat ate, and she also ranked their activity level on a scale from 1 to 10 each day. She found the line of best fit for the data has the equation y=0.23x+4.1, where x represents the activity level and y
represents the number of meals eaten.
If a cat had an activity level of about 9,
approximately how many meals is it likely to have eaten?

Give the person above me brainlyest for helping!
Step-by-step explanation:
The coefficient of correlation for the given data of x and y is 0.78.
x and y have a strong, positive correlation
What is Coefficient of Correlation?
A correlation coefficient is a number between -1 and 1 that tells you the strength and direction of a relationship between variables. In other words, it reflects how similar the measurements of two or more variables are across a dataset.
Here, given values of x and y
x 1 2 3 4 5 6
y 3 4 9 7 2 18
xy 3 8 27 28 10 108
x² 1 4 9 16 25 36
y² 9 16 81 49 4 324
∑x = 21, ∑y = 43, ∑xy = 194, ∑x² = 91, ∑y² = 483, n = 6
Now, Correlation between x and y
r = (n∑xy - ∑x.∑y)/ √[{n∑x²- (∑x)²}{n∑y² - (∑y)²}]
r = ( 6 X 194 - 21 X 43 ) / √[ {6 X 91 - (21)²}{ 6 X 483 - (43)²}]
r = ( 1164 - 903) / √( 546 - 441)(2898 - 1849)
r = 261 / √ 105 X 1049
r = 261 / √110145
r = 261 / 331.88
r = 0.78
Thus, The coefficient of correlation for the given data of x and y is 0.78.
x and y have a strong, positive correlation
