(D) A stratified random sample
Step-by-step explanation:
A stratified random samples are samples that involves the use of stratified random sampling (or stratification) which involves the partition or division of a population into smaller subgroups (called strata). The division is done based on some shared characteristics and attributes. The case above is a stratified random sample because it involves the division of shoreline(population) into 100-foot plots(stratas or subgroups).
Answer:
x = 20
Step-by-step explanation:
Angle 2 and Angle 5 are corresponding angles
Corresponding angles are congruent
If angle 2 = 3x - 20 and angle 5 = x + 20
Then 3x - 20 must equal x + 20 ( because corresponding angles are congruent )
Notice that weve just created an equation that we can use to solve for x
We now solve for x using the equation we created
3x - 20 = x + 20
Step 1 add 20 to both sides
3x = x + 40
Step 2 Subtract x from both sides
2x = 40
Step 3 divide both sides by 2
x = 20

Answer:
30 yards per minute.
Step-by-step explanation:
Unit rate is basically when the denominator is 1. In this case, 450 is divisible by 15, so if you divide that, you get 30.
