Twelve is the product of three and a number.
Product: an answer given due to multiplication.
Since Twelve is described as the product of three and a number, it is our answer.
?? = 12
Twelve is the product of three and a number. since it is a product, that means their was multiplication involved. using the clues "Three and a number", we can deduce that these are multiplied to get our product, which is twelve.
if it says number, then that represents the unknown variable of the equation. this is usually defined as X or any other letter(s) if their is more than one variable or if it is specified.
3X = 12
Answer: he must pay $650 interest
Step-by-step explanation:
2000 x 0.650 x 1/2 = 650
Answer: y = -2/3x + 5
Step-by-step explanation: you find the slope by finding “rise/run”. the rise is -2, and the run is 3, so the slope is -2/3. the y intercept is 5
To find the slope of the line, you need two points.
(-2 , 5) and (3 , -5)
5 - (-5) / -2 - 3
10 / -5 = -2
The slope of the line is -2. So your answer is C.
Answer:
D. All of the above
Step-by-step explanation:
Samples may be classified as:
Random: Basically, put all the options into a hat and drawn some of them.
Systematic: Every kth element is taken. For example, you want to survey something on the street, you interview every 5th person, for example.
Cluster: Divides population into groups, called clusters, and each element in the cluster is surveyed.
Stratified: Also divides the population into groups. However, then only some elements of the group are surveyed.
In this problem:
Two random samples are selected and combined. The combination is a random sample. So A. is correct.
They are not balanced. More male professors than female are chosen. So B. is correct.
The teachers are divided into groups(male and female). And some members of each group are selected. So C. is correct.
So the correct answer is:
D. All of the above
