The correct answer is: 3Explanation:
Instead of sharing the conventional tedious, method, let me share with you the simple trick here to solve these types of questions without using the calculator:
Given
![log_464](https://tex.z-dn.net/?f=log_464)
It is essentially saying that WHAT power of 4(which is the base of log) gives us the value 64. You need to find the answer to that "WHAT."
Well
![4^1 = 4 \\ 4^2 = 16 \\ 4^3 = 64](https://tex.z-dn.net/?f=4%5E1%20%3D%204%20%5C%5C%0A4%5E2%20%3D%2016%20%5C%5C%0A4%5E3%20%3D%2064)
Hence the answer is "3".
Answer:
point of estimate p = x/n
Step-by-step explanation:
p is the point estimate for the population , x is the number of success, n is the sample size.
p = Upper bound + Lower bond/ 2 for population proportion
x = Upper bond + Lower bond /2 for population mean
E = Upper bond - Lower bond /2 E is margin of error
Using equivalent decimals, the correct option regarding which lake lost the least amount of water is:
<h3>How to find the equivalent decimals?</h3>
- For a fraction, we have to divide the numerator by the denominator to find the equivalent decimal.
- For a percentage, we just have to divide the percentage by 100%.
Hence, for the three lakes, the equivalent amounts are given by:
- Lake Jensen: 1/3 = 0.3333.
- Lake Parlow: 34% = 34/100 = 0.34.
- Lake Stockton: 147/300 = 0.49.
The smallest equivalent decimal is of 0.33, hence Lake Jensen lost the least amount of water and option A is correct.

She saves £400
She spends £640
1+2+8= 11
And she likes 8 out of the 11 tracks
So the probability is 8/11 or about 73%
