Answer:
44%
Step-by-step explanation:
Solution:
Calculate percentage change
from V1 = 2000 to V2 = 1120
(V2−V1)|V1|×100
=(1120−2000)|2000|×100
= −8802000×100
= −0.44×100
= −44%change
= 44%decrease
Answer:
Use z = (x - μ)/σ or x = zσ + μ
Given: μ = 0 oC, σ = 1.00 oC
94% = .9400 on a z-table falls half-way between z = 1.55 and z = 1.56 --> z = 1.555
x = 1.555(1.00 oC) + 0 oC = 1.555 oC
P94 = 1.555 oC
Step-by-step explanation:
I believe it is D. hope this helps
Answer combine 1/2 and x.
X/2+2/3=1/6
Subtract 2/3 from both sides of the equation
X/2=1/6-2/3
Simplify the right side of the equation
-2/3 as a fraction with a common denominator, multiply by 2/2
X/2=1/6-2/3 x 2/2
Multiply 3 by 2
X/2 = 1/6 - 2/6 x 2
Combine the numerators over the common denominator
X/2 = 1-2 x2/ 6
Simplify the numerator
Multiply by -2 by 2
X/2 =1-4/6
Subtract 4 from 1
X/2= -3/6
Cancel the common factor of -3 and 6
Factor 3 out of -3
X/2 = 3(-1)/6
Cancel the common factor of 6
X/2 = 3 .-1/3.2
Rewrite the expression
X/2 = -1/2
Move the negative in front of the fraction
X/2= -1/2
Since both sides have the same Denominator the numerators must be equal.
X=-1
27 and 28 because their sum is 55 and 28-27=1
