65754.6 because the 9 in the hundreds place bumps up the five in the tenths
Answer: 

Step-by-step explanation:
- A null hypothesis is a type of hypothesis that is used in statistics that assumes there is no difference between particular characteristics of a population wheres the alternative hypothesis shows that there is a difference.
Given: A 37 bag sample had a mean of 421 grams.
Let
be the population mean.
Then, the null hypothesis would be:

whereas the alternative hypothesis would be:

Answer:
option C is correct
Step-by-step explanation:
We need to find the determinant.
= -1(7*9 - 3*9)-( -3)(4*9 - 3*3) -2(4*9 -7*3)
= -1(63-27) +3 (36 - 9) -2( 36- 21)
= -1(36)+3(27)-2(15)
= -36+81-30
= 15
Option C is correct
Answer:

Step-by-step explanation:

It's an equation of a linear function in the slope-intercept form:

<em>m</em><em> - slope</em>
<em>b</em><em> - y-intercept</em>
The domain of any linear function is the set of all real numbers.
The range of any linear function where m ≠ 0 is the set of all real number.
If m = 0, then the equation of a line is y = b. Then the range is {b}.
We have m = 1/4 ≠ 0. Therefore the range is the set of any real numbers.
