Answer:
Cost of Washer: $897
Cost of Dryer: $299
Step By Step Explanation:
washer + dryer = $1196
dryer = x
washer = 3x
x + 3x = $1196
4x = $1196
x = $1196 ÷ 4
x = $299
therefore, dryer = $299
and washer = $299 * 3
washer = $897
ANSWER
The value of this function at x=-1 is 1
EXPLANATION
The given function is
We want to find the value of this function at x=-1.
We substitute x=-1 into the function to obtain:
We multiply out to obtain:
Therefore the value of this function at x=-1 is 1.
Answer: (B) stratified random sampling.
Step-by-step explanation:
- A stratified random sampling technique is a sampling technique in which the researcher includes the participants from each group.
- He divides the entire population into groups and then he randomly selects participant from that groups of known as strata .
Here, Math department can send 6 people to a national convention and they would like to send 4 students out of 30 and 2 faculty members out of 6.
The department is considering both groups or strata of Students and faculty members as well.
And they selected 4 students randomly out of 30, and then 2 faculty members are randomly selected from the six.
Therefore , This is an example of stratified random sampling.
Hence, the correct option is (B) stratified random sampling.
