A random sample of 100 male and females was selected. Let muf be the population mean number of hours spent playing online games for females and let mum be the population mean number of hours spent playing online games for males.
Step-by-step explanation:
So we have
2 choices for cloth
3 choices for leather
2 choices for cloth
we have to multiply each individually
we just add them
3 leather+2 cloth=5 choices
she is wrong
because the asnwer is 5
ΔACB and ΔMNB are similar. Therefore the corresponding sides are in proportion:
Substitute:
Surface area of a sphere = <span>4π<span>r2</span></span>
the volume of a sphere= <span><span>43</span>π<span>r3</span></span>
so <span>5000π=<span>4/3</span><span>πr3
</span></span><span>> r^3 = 5000 x 3 / 4
=>
r^3 = 3750
</span>taking cube root on both sides
r=15.53616
hope it helps
