Answer:
Ans.
X=3
Step-by-step explanation:
Ok, there are several ways to solve this, I chose the one that can be more visual friendly to you.
SInce the log are based 2, we are going to be using this base on both sides of the equation, so, let Y = (3X+7).
This means.
Since Y = (3X+7)
Therefore X=3
Best of luck.
Answer:
The probability that the sample proportion will differ from the population proportion by less than 6% is 0.992.
Step-by-step explanation:
According to the Central limit theorem, if from an unknown population large samples of sizes n > 30, are selected and the sample proportion for each sample is computed then the sampling distribution of sample proportion follows a Normal distribution.
The mean of this sampling distribution of sample proportion is:
The standard deviation of this sampling distribution of sample proportion is:
The information provided is:
As the sample size is large, i.e. <em>n</em> = 276 > 30, the Central limit theorem can be used to approximate the sampling distribution of sample proportion.
Compute the value of as follows:
Thus, the probability that the sample proportion will differ from the population proportion by less than 6% is 0.992.
They are both equal to y so you can set them equal to each other to solve for x:
14x - 6 = -4x + 48
18x = 54
x = 3
To solve for y just plug 3 into the x of one of the given equations
y = 14(3) - 6
y = 42 - 6
y = 36
To check:
36 = 14(3) - 6
36 = 42 - 6
36 = 36
36 = -4(3) + 48
36 = -12 + 48
36 = 36
Hope this helped!
