Given there are equal amounts of each color and four colors in total, the probability is calculated out of four. As there's an equal quantity of both red and blue, the chance of drawing either a red or blue marble is 2/4.
-10w - 400 = o
w= weeks
o = remaining balance
Each of the six payments amounts to $41.50
Step-by-step breakdown:
Given,
Total cost of the bike including taxes = $349
Initial payment = $100
Remaining balance = Total cost of bike - Initial payment
Remaining balance = 349 - 100
Remaining balance = $249
She opts to pay in six equal installments, so we divide the total remaining by 6.
Monthly payment = 
Monthly payment = 
Each of the six payments amounts to $41.50

Hello!
Stratified sampling involves the categorization of the population into subgroups based on pre-established criteria for the study. These subgroups consist of homogeneous units concerning the relevant characteristics. In this instance, individuals in the groups will represent only one of the two potential opinions (support or not support) and not both.
The researcher determines the sample size desired, considering several factors such as finances, material availability, and accessibility to experimental subjects (for instance, if they are endangered species, larger sample sizes may not be feasible).
One might conduct proportionate stratified sampling by selecting a proportion of respondents who answered "yes" along with those who answered "no."
In this sampling method, taking a specific proportion from each subgroup allows for a more straightforward extrapolation of results to the overall populations. For example, if you needed a sample size of n = 20, each stratum would ideally contain half, meaning 10 from the “yes” group and 10 from the “no” group.
I hope this is helpful!
