Answer:
slope = -
Step-by-step explanation:
calculate the slope m using the slope formula
m =
with (x₁, y₁ ) = (3, 2 ) and (x₂, y₂ ) = (- 3, 4 )
m = =
= -
Answer:
A.
B.
C.
Step-by-step explanation:
A. . Any number could work as long as the coefficients for x and y stays the same. You are basically imposing that the quantity 2x-4y (if you bring 4y to the LHS) is equal to both -3 AND
, or any number you like. But yesterday was 3/14 so let's pick a fun number!
B. Or
. Or as long as you don't pick the same ratios of x and y you're golden. But x=1 is the easiest that comes to mind
C. . To get infinitely many solutions you just have to rewrite the equation again. Maybe move things around if you prefer, or multiply everything by a number you lile.
Z=kx/y
7.9=k11/14
Cross multiply
K11=7.9x14
K =7.9x14/11
K=10.1
........
Z= kx15/22
Z=10.1x15/12
Z=12.625
Answer:
A) 2.58
B) 1.96
C) 1.65
Step-by-step explanation:
A hypothesis used to test that
against the alternatives not equal to 10
if null hypothesis is true, then distribution of test statics follow
for two sided alternatives hypothesis , then P value is
(1)
a)significance level
from 1 eq we get
Therefore FROM Z TABLE
B) significance level
from 1st equation we get
Therefore FROM Z TABLE
C) significance level
from 1 eq we get
Therefore FROM Z TABLE
