x = normal water level
x - 12 - 13 = x - 25
so it is 25 feet below the normal water level
Okay so multiply everything by 2 6yrds×2=12yrds. 9ft×2=18ft. 4in×2=8in. So the answer is: 12yrds 18ft 8in
Answer: Stratified sampling
Step-by-step explanation:
Stratified sampling is a random sampling method in which the population is divided into non-coinciding groups are called strata and a sample is picked out by some design within each stratum.
Given: A researcher wants to survey people from different age groups to analyze voting patterns.
Thus he will make different groups according to different ages to analyze voting patterns that are called stratum.
Thus, Stratified sampling best accomplish this goal.
Answer:
2x + 4y = 12 and y = -1/2x + 3
Answer:
m<7 = 61
Step-by-step explanation:
These angles (<7, and <8) are adjacent to each other (they are next to each other), therefore they are supplementary (add up to 180).
180 - 119 = m<7
