Answer: 272.85
(It’s 21.4 times 12.75)
Answer:
AC = 30
Step-by-step explanation:
Start with:
Combine like terms.
Subtract from both sides of the equation.
Subtract from both sides of the equation.
Then, substitute for in
Multiply.
Finally, add.
One solution was found : t ≤ -13 (number 4)
Pull out like factors :
-3t - 39 = -3 • (t + 13)
Divide both sides by -3
Remember to flip the inequality sign:
Solve Basic Inequality :
Subtract 13 from both sides to get t≤−13
first you find the slope by making using the quation for slope
(7-3)/(0-5) and you find your slope is 4/-5. Then you can plug this into point slope form using on of the coordinates so:
y-y1=m(x-x1) --> y-3=-4/5(x-5)
then you distribute the -1 so -----> y-3=-4/5x+4 and then move the 3 over
so the answer is y= -4/5x+7
Answer:
a. is effective for use in school research.
Step-by-step explanation:
Cluster sampling is the sampling whereby we pick random few sample from the population to serve as the sample population called cluster. This cluster usually have uniform characteristics among them.
The main advantage of cluster sampling is that it is effective school research because of its cheapness and doesn't require much resources during the sampling process.
The other options are not correct because Cluster sampling have High sampling error and its biased sample.
