3x+5y=2
9x+11y=14
∣⋅(−3)
−9x−15y=−6
9x+11y=14
add both sides of equations
. −4y=8 ∣:(=4)
. y=−2
substitute the value of y to the first equation
3x+5⋅(−2)=2
3x−10=2 ∣+10
3x=12 ∣:3
x=4
Answer: x=4; y=−2→(4; −2)
Answer:
p percent of the observations are less than the value and (100 - p) percent are more than this value.
Step-by-step explanation:
Given : The pth percentile is a value such that approximately
Solution :
Definition : A percentile is a measure used in statistics indicating the value below which a given percentage of observations in a group of observations falls
So, The pth percentile means p percentage of observations in a group of observations falls bellow the value
So, (100-p) percentage of observations in a group of observations falls above the value
So, Option a is true
Hence p percent of the observations are less than the value and (100 - p) percent are more than this value.
Answer:
Step-by-step explanation:
I believe it's C.33 because if 4×33=132 the rest are smaller and one of the is equal,
So in my opinion It's 33
26 inches. Technically, since this is a perimeter problem, you need to add each length to itself and then the others. If this is confusing, you essentially need to do 5+5+8+8=26 because you have two of the fives and two eights. Perimeter is much easier than area, I promise you that
X-6x=56
-5x=56/:(-5)
x=-56/5
x=-11 1/5
