Which equation is a linear function? y=2^x -1 y=x/2-5 y=2/x +3 y=x^2 +7
1 answer:
Answer:
Second Choice.
Step-by-step explanation:
That is the linear function. Any coefficients with higher degrees won't be considered as a linear function.
So we can cut out the first and last choice.
Then we have only two choices which are
The second equation is called <u>Rational</u><u> </u><u>Function</u><u> </u>where a variable is a denominator.
Therefore, the correct answer is second choice.

Answer:
We conclude that the machine is under filling the bags.
Step-by-step explanation:
We are given the following in the question:
Population mean, μ = 436.0 gram
Sample mean, = 429.0 grams
Sample size, n = 40
Alpha, α = 0.05
Population standard deviation, σ = 23.0 grams
First, we design the null and the alternate hypothesis
We use one-tailed(left) z test to perform this hypothesis.
Formula:
Putting all the values, we have
Now,
Since,
We reject the null hypothesis and accept the alternate hypothesis. Thus, we conclude that the machine is under filling the bags.
