Answer: 13/25
Step-by-step explanation: Think of 0.52 as fifty-two hundredths which can be written as the fraction 52/100.
Since 52/100 is not in lowest terms, we divide the numerator and the denominator by the greatest common factor of 52 and 100 which is 14 and we get the equivalent fraction 13/25.
Therefore, 0.52 is equivalent to 13/25.
You must factor.
The factored form is equal to the assigned form.
Values a, b correspond to the factored 1, -1.
Value of x however remains unknown. But we can change that.
Given factored result,
We can set expression equal to 0 then find such x that when added with number a or b results with 0.
Hence x has 2 solutions.
Hope this helps.
Answer:
1/2x + 17 = 8
Step-by-step explanation:
1/2x + 17 = 8
1/2x = -9
x = -9/0.5
x = -18
Answer:
The maximal margin of error associated with a 95% confidence interval for the true population mean is 2.238.
Step-by-step explanation:
We have given,
The sample size n=42
The sample mean
The population standard deviation
Let be the level of significance = 0.05
Using the z-distribution table,
The critical value at 5% level of significance and two tailed z-distribution is
The value of margin of error is
The maximal margin of error associated with a 95% confidence interval for the true population mean is 2.238.
