Answer:  H_0:\mu=421

H_a : \mu\neq421

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 \mu be the population mean.

Then, the null hypothesis would be:

H_0:\mu=421

whereas the alternative hypothesis would be:

H_a : \mu\neq421

If k = -3 what is the value of k + (2k - 10) ?<br><br> A. –19<br> B. –7 <br> C. 1<br> D. –14
gladu [14]

Answer:

A

Step-by-step explanation:

We have the expression k+(2k-10)

We want to find the value when k is -3. So, substitute -3 for k and evaluate:

\Rightarrow (-3)+(2(-3)-10)

Multiply:

=-3+(-6-10)

Subtract:

=-3+(-16)

Add:

=-19

Therefore, our answer is A.

Why did the math teacher open a window company?
umka2103 [35]

A math teacher opened a window company because he loves seeing shapes or geometrical polygons such as rectagles, squares or quadrilaterals in general as well as triangles in his works. Of course, the math teacher is already familiar with these shapes and how to calculate the angles in between.
