Answer:
positive 48 ..yan yung pagkakaalam ko
Each friend gets two each
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:
Step-by-step explanation:
<u>The relationship is:</u>
<u>We have points on the graph:</u>
- (9, 28.26) and (18, 56.52)
<u>Use one of the points, substitute into equation and solve for r:</u>
- 28.26 = 3.14*9*r²
- r² = 28.26/28.26
- r² = 1
- r = 1
Double the number like 2 x5 would be 5+5
