<span>P(black socks): 24/42 or 12/21
P(black socks without replacement): 23/41. Consequently, the chance of randomly selecting 2 black socks, without replacement, from the basket is 12/21×23/41=276/861, equivalent to 32%. Hope this helps!</span>
An airplane flying at a speed of 950 kilometers per hour would take 0.0010526 hours to travel 1.00 kilometer.
Initially, you must determine the circle's circumference since one complete rotation corresponds to one length of the circumference. The formula to calculate circumference is C=2πr or C=πd; for a diameter of 1 meter, the circumference equals π1, which is simply π. Therefore, if it makes 8000 rotations, the distance traveled would be 8000π meters.
Answer:
Yes, La Tasha is right, since the correlation coefficient amounts to r=0

Tim operates a delivery service for local retailers, charging $1.25 for deliveries within 1.5 miles, $1.70 for distances from 1.5 miles to less than 1.75 miles, $2.15 for distances from 1.75 miles to less than 2 miles, and so on. If he increases his prices by 10%, how much will he charge for a 3 1/8 mile delivery? The cost for moving an extra 1/4 mile (between 1.75 miles and 1.5 miles) is $0.45 (calculated as $1.70 - $1.25). So, with a 10% hike, this charge becomes 1.1 × $0.45 = $0.495. Here would be Tim's adjusted rates: $1.25 for 1.5 miles, $1.745 for 1.5 to 1.75 miles, $2.24 for 1.75 to 2 miles, $2.735 for 2 to 2.25 miles, $3.23 for 2.25 to 2.5 miles, $3.725 for 2.5 to 2.75 miles, $4.22 for 2.75 to 3 miles, and $4.715 for 3 miles to 3.25 miles. Therefore, delivering a package 3 1/8 miles would cost $4.715.
