Answer:
4.4x+1.5
Step-by-step explanation:
1.6x+7.3+-0.6x+2-7.8-3.4x =
1.6x -0.6x+3.4x +7.3+2-7.8=
4.4x + 1.5
Answer:
table:
.1, .25, .35, .2, .1
p(x=4) = .1
p(x<2) = .35
p(3≤x≤4)= .55
1.95, 1.12
Step-by-step explanation:
this is kind of hard to read, but i think i've got it
mean:
0*.1+1*.25+2*.35+3*.2+4*.1= 1.95
The second moment:
0²*.1+1²*.25+2²*.35+3²*.2+4²*.1= 5.05
the variance is the second moment minus the first moment squared (first moment is the mean) and then the standard deviation is the square root of the mean
5.05-1.95²= 1.2475 √1.2475= 1.1169 or 1.12
Answer:
(8,6)
Explanation:
The middle of the 2 x coordinates, 8 and -2 is 3. The middle of the 2 y coordinates, -6 and 6 is 0. Hence (8,6)
Answer:
k=13t/t+6
Step-by-step explanation:
kt=13t−2k(3)
Step 1: Add 6k to both sides.
kt+6k=−6k+13t+6k
kt+6k=13t
Step 2: Factor out variable k.
k(t+6)=13t
Step 3: Divide both sides by t+6.
k(t+6)t+6=13tt+6
k=13t/t+6
Well if you know what a -X graph looks like (a diagonal line that goes from the top left to the bottom right, reading the graph from left to right). The answer is simply everything under that line. However, in this case, it also includes the space that the line is in itself. This is because it's less than OR equal to -x
