Sweet T has 2 orange picks for every 5 green. If there are 21 picks In all, how many picks are orange?

Which 2 equations would you use to solve this system?

slega [8]

Answer:

x-y=4

and

x+y=32 is your equation

difference of two number =x-y is equal to 4

sum of two number=x+y is equal to 32

x-y=4.......(1)

x+y=32.......(2)

adding equation 1 and 2

x-y +x+y=4+32

2x=36

x=36/2=16answer

substituting value of y in equation 1

16-y=4

16-4=y

y=12 answer

Solve: -23 = x - 23 * please help I'll add extra points

Serjik [45]

X=0

-23 = x - 23

Step 1 cancel equal terms on both sides of the equation

0=x

Step 2 swap the sides of the equation

x=0

dentify which type of sampling is used: random, systematic, convenience, stratified, or cluster. To determine customer opinio

Rudik [331]

Answer:

The type of sampling used is the Cluster sampling technique.

Step-by-step explanation:

- Random Sampling

In random sampling, each passenger would have an equal chance of being surveyed. If this particular scenario wanted to use random sampling, they would have used computer generated random passenger numbers and surveyed them, not just passengers all on the same bus picked randomly.

- Systematic sampling is easier than random sampling. In systematic sampling, a particular number, n, is counted repeatedly and each of the nth passengers is picked to be sampled.

- Convenience Sampling

This is the worst sampling technique. It is also the easiest. In Convenience sampling, the surveyor just surveys the first set of passengers that they find.

- Stratified Sampling

Stratified sampling divides the population into groups called strata. A sample is taken from each of these strata using either random, systematic, or convenience sampling.

- Cluster sampling

Cluster Sampling divides the population into groups which are called clusters or blocks (the different buses). The clusters are selected randomly, and every element in the selected clusters is surveyed (each passenger on the selected buses, is surveyed!). Evidently the answer to the question!

Rewrite the expression, the quotient of k decreased by 4 and 9, using the division symbol and as a fraction.

AlexFokin [52]

Answer:

(k - 4) ÷ 9

(k - 4) / 9

Step-by-step explanation:

k decreased by 4 = k - 4

quotient of k decreased by 4 and 9

= (k - 4) ÷ 9 (using division sign)

Or

= (k - 4) / 9 (as a fraction)
