2+4+5+6+8+2+5+6= 38/8 = 4.75
2+4+5+6+8+2+5+6+7 = 45/9 = 5
5 - 4.75= 0.25
C. The mean increased by 0.25
Answer:
Large Jar
Step-by-step explanation:
Large jar- 440g for £1.54
- Cost per gram for the large jar = £1.54 ÷ 440g =£0.0035 per gram
Small jar- 340g for £1.26
- Cost per gram for the small jar = £1.26÷ 340g =£0.0037 per gram
Since the cost per gram of the large jar is lower, <u>the large jar offers best value for money.</u>
Answer:
A. Five places to the left
Step-by-step explanation:
Scientific notation is a method used so we can show a very big/small number easier. Rather than putting so many zeroes, we put the number in the format of a number multiplied by 10^x.
Before putting a number into scientific notation, you need to know which number is a significant figures. In this question, there are two significant figure which is 39, all zeroes on the right is insignificant. We can move the decimal to convert the number into 3.9 * 10^5. Basically you need to move the decimal to the left if the exponent positive, but move it to the right if its negative. The exponent is +5 so we move the decimal points 5 places to the left.
