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
The table that show the function <span>y = -2x + 4? is table A.</span>
Take the length as 'x'
Width = 2x - 2
Perimeter = 44 [ Formula = 2(l + w) ]
2 (l + w) = 44
2 (x + 2x - 2) = 44
2 (3x - 2) = 44
6x - 4 = 44
6x = 44 + 4
6x = 48
x = 48/6
<u>x </u><u>=</u><u> </u><u>8</u> => length
Width = 2x - 2 = 2(8) - 2 = <u>1</u><u>4</u><u> </u><u>units.</u>
Hope it helps!
