The sample was 10 numbers.
4 of the numbers are less than 301.
So 4 out of 10 would be defective.
4/10 = 0.4 x 100 = 40%
He would expect 40% to be defective.
The answer is B. h=<span>V<span>2π<span>r<span>2</span></span></span></span>
Step-by-step explanation:
3x(x2 + 2x – 6) + 4(x2
– 6x + 2)
48 points gained in those 3 days.
Subtract 220 with 48, then add 96. Last step would be subtracting 220 with the amount they have now in those 3 days to find how much points the stock market gained in those 3 days.
Subtract 220-48.It‘ll be 172.
Add 172 with 96. 172+96=268.
Subtract 268 with how much points the stock market had 3 days ago. 268-220.
Sot eh stock market gained 48 points in 3 days.
<span>4+6(7x+7)
= 4 + 42x + 42
= 42x + 46
