Answer:
13.79%
Step-by-step explanation:
A solution is made by dissolving 24 millimeters of saline in 150 millimeters of pure solution
Therefore percent of saline in the pure solution can be calculated as follows
= 24/24+150 × 100
= 24/174 ×100
= 0.1379 ×100
= 13.79%
Hence the percent of saline in the pure solution is 13.79%
Answer:
Option B) the minimum acceptable chance of making a type I error.
Step-by-step explanation:
We define significance level as:
- It is denoted by α.
- It is the probability of rejecting the null hypothesis when it is true.
- Thus, it is the type I error.
- Lower significance levels indicate that stronger evidence are required to reject the null hypothesis.
- We compare the significance level to the p-value to decide whether to accept or reject the null hypothesis.
- It is the probability of false positive.
- The probability of making a type I error is α, which is the level of significance.
- For example: A significance level of 0.05 indicates that there is a 5% chance that we are wrong when we reject the null hypothesis because it is actually true. To lower this risk, you must use a lower value for α.
Option B) the minimum acceptable chance of making a type I error.
A 4x25=100 10x10=100 making 100 a common multiple of 4 and 10.
Correspondence theories claim that true beliefs and true statements correspond to the actual state of affairs.
1/27 = 3^(-3)
3^(3x+6) = 3^(-3)
When bases are the same, all you need to do is set the exponents equal to each other:
3x+6 = -3
3x = -9
x = -3
