Let's say that each pizza is sliced into 8 equal sized pieces, I have to make all of the fraction have the denominator of 8.
Conor: 1/4 * 2/2 = 2/8
Tyler: 3/4 * 2/2 = 6/8
Brandon: 2/8
Audrey: 4/8
Then I'll put the fractions in order from least to greatest. 2/8, 2/8, 4/8, 6/8. Then you would have to multiply each fraction by 2 since there are two pizzas that have 8 equally sized pieces.
Brandon: 2/8 *2/2 = 4/16
Conor: 2/8 * 2/2 = 4/16
Audrey: 4/8 * 2/2 = 8/16
Tyler: 6/8 * 2/2= 12/16
This means that Tyler ate the most of the two pizzas.
Answer:
(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).
<span>System 1 and system 2, because the second equation in system 2 is obtained by adding the first equation in system 1 to two times the second equation in system 1
This is the correct answer because not only is it true but it also follows the property of solving systems of equations with adding the equations. To prove that it is true:
2nd equation in system #2 = 1st equation in system #1 + 2(2nd equation in system #1)
</span>10x − 7y = 18 == 4x − 5y = 2 + 2(<span>3x − y = 8)
10x - 7y = 18 == 4x - 5y = 2 + 6x - 2y = 16
10x = 7y = 18 == 10x - 7y = 18</span>
