The equation y = 14x/z represents _____________ variation.
A.
inverse
B.
direct
C.
combined
D.
joint
Answer:
D. joint variation
Step-by-step explanation:
y = 14x/z
y is directly proportional to x and inversely proportional to y
Constant of proportionality = 14
Direct variation is given as
y = kx
Where, k = constant of proportionality
Inverse variation is given as
y = k/z
Where, k = constant of proportionality
When they are jointly combined
y = kx/z

a whale costs $14700 and depreciates in value by 8% per year. When will the whale be worth $100
Answer:
x = 60
Step-by-step explanation:
The question is asking
$14,700 * (1 - 8%)^x = $100
$14,700 * (1 - 0.08)^x = $100
$14,700 * (0.92)^x = $100
(0.92)^x = $100/$14,700
log(0.92^x) = log($100/$14,700)
x * log(0.92) = log(0.0068027)
x = log(0.0068027)/log(0.92)
x = 59.85
Since this question is asking in terms of years, we always round up (in this case to 60), as it won't fully be worth $100 by the beginning of the 59th year.

How many blue pens were there to start with?
Answer:
180 blue 70 red
Step-by-step explanation:
b= blue r = red
b+r = 250
r = (250-b)
If 40% is removed the rest is 60%
If the 70% is removed the rest is 30%
0.6b + 0.3(250-b) = 129
0.6b + 75 - 0.3b = 129
0.3b = 54
divide by 0.3
b = 180
250-180 = 70
60% 0f 180 = 108
30% of 70 = 21
108 +21 = 129

Show work please
Answer:
-6 = x
Step-by-step explanation:
7 = x + 2x - 5 - 5x
7 = 3x - 5 - 5x
7 = -2x -5

Michael is writing an article for the school newspaper. He wants to know which subject (math, reading, science, history, or physical education)
is most liked. He is trying to decide who to survey.
Which population sample does NOT produce a biased result?
A. He asks the school’s teachers
B. He asks his friends after school
C. He asks the students in his math class
D. He asks students he meets in the hallways
E. He asks every fifth student arriving at school
Answer: E is the answer
Step-by-step explanation:
The population sample that does not produce a biased result is when he asks every fifth student arriving at school. The correct option is E.
What is a survey?Surveys can be used to determine how representative each person's opinions and experiences are.
When conducted properly, surveys offer precise data about people's beliefs and actions that can be utilized to inform significant decisions.
A huge population's characteristics can be described through surveys. No other research methodology can offer such a wide range of capabilities.
This guarantees a more accurate sample to collect focused results from which to draw conclusions and make significant judgments.
Survey bias is when a question is worded or presented in a way that encourages individuals to select one response over another.
The same holds true if your queries are challenging for customers to comprehend and honestly answer.
As, when he asks every fifth student arriving at school, it can lead to an unbiased result.
Thus, the correct option is E.
