Answer:


Step-by-step explanation:
From the question we are told that
Number of math tests n=15
standard deviation 1 
standard deviation 1 
Generally given the two tailed test the null hypothesis is given as

Generally given the two tailed test the null hypothesis is given as

10x+6y=24, 15x+9y=36. If you multiply both sides by a number (2,3 etc) you get an equation that would have infinitely many solutions because they’re the same equation. Hope this could help you!! Gamer time
Answer:
B.) is the best deal
Step-by-step explanation:
A.) three six packs is $3 for each pack minus $2
$3 + $3 + $3 = $9
$9 - $2 = $7
B.) guessing the three six packs is $3 then minusing 25%
$3 - 25% = $2.25
Refer to c^2=a^2+b^2 (^2 means squared)
C is the hypotenuse and will be the longest measure
So 15^2= 9^2+12^2
225=225
If both sides are equal then the triangle is a right triangle, if the hypotenuse (or c) is lower or higher than you can determine whether it’s obtuse or acute
It would be a right triangle
It’s a ushndu hahaha hahaha Han shxvdbck dhuddj
