Answer:
Mean= 44.2
Median=45
Mode=6
Range=50
Step-by-step explanation:
Mean= (10x1 +30x2 + 40x3 +50x2 +60x4)/12
= 530/12
=44.17
=44.2
Median= 40+50 /2
=45
Mode= 6
Range= 60-10
=50
Answer:
0.1
Step-by-step explanation:
anything after the decimal (.) becomes a sogfig
2500 because 25% of 2000 is 500 and 2000+500 is 2500? tell me if im wrong!
<em>Answer:</em>
<em>n = 1067</em>
<em>Step-by-step explanation:</em>
<em />
<em>Since nothing is known, we would assume that 50% of the computers use the new operating system.
</em>
<em>So, standard error = 0.5/SQRT(n)
</em>
<em>Z-value for a 95% CI = 1.9596
</em>
<em>So, margin of error = 1.9596 x 0.5 / SQRT(n) = 0.03
</em>
<em>So, n = 1067 (approx.)</em>
<em />
<em>This will be your approximate answer : n = 1067</em>
Hey!

Writing scientific notation in numeral is solving for the equation.
Multiply 10 to 6.4 seven times.
6.4 x 10 = 64
64 x 10 = 640
640 x 10 = 6,400
6,400 x 10 = 64,000
64,000 x 10 = 640,000
640,000 x 10 = 6,400,000
6,400,000 x 10 = 64,000,000
