Answer:
use highlighters and go through your notes to highlight important info. I use different highlights for different sections to help separate the information. The different colors on different parts of the notes really help me know what the info for the notes was about and it's good to review them by going over them in color. Hopefully this helps :)
To answer this item, we are first to calculate the values of the length of this particular metal rod that is 0.045 cm less than the given,
Lower limit = 20.5 cm - 0.045 cm = 20.455 cm
Also, we calculate for the upper limit by adding 0.045 cm to the given length.
Upper limit = 20.5 cm + 0.045 cm = 20.545 cm
Thus, the answer to this item is D.
The conclusion based on the mean of the ball and the distance traveled is D. Inferences cannot be made about all the golf balls produced on that day.
<h3>How to deduce the inference?</h3>
From the information given, a golf pro randomly selects a ball, not knowing the type of ball, hits it and end of the session, the mean distance traveled for the new type of golf ball was found to be greater than the mean distance for the original-style golf ball.
In this case, inferences cannot be made about all the golf balls produced on that day; however, the conclusion can be made that the new type of golf balls travel farther than the original type of golf ball for this golf pro.

Answer:
£121
Step-by-step explanation:
5/12 of the total coins = 5/12 x 96 = 40 ⇒ 40 coins are £2 coins
26 of the coins are £1 coins
Number of 50p coins = 96 - 40 - 26 = 30 ⇒ 30 of the coins are 50p coins
Total money collected = 40 x £2 + 26 x £1 + 30 x £0.50 = £121
(rememberinf to convert 50p into £s)
