180-106=74
X is congruent to 2y
x=74
74/2= 37
y=37

(4z+6) is congruent to 106
106-6= 100
100/4 = 25
z=25

When finding the margin of error for the mean of a normally distributed population from a sample, what is Alpha, assuming a conf

MArishka [77]

The value of alpha is 0.26, assuming a confidence level of 74%.

<h3>What is the margin of error?</h3>

The significance level α is the probability of making the wrong decision when the null hypothesis is true.

Alpha levels which is also called as significance levels are used in hypothesis tests.

Given

When finding the margin of error for the mean of a normally distributed population from a sample.

The confidence interval = 74% = 0.74.

The value of the alpha is given by;

$\rm \alpha =1- Confidence \ interval$

Substitute all the values in the formula

$\rm \alpha =1- Confidence \ interval\\\\\alpha=1-0.74\\\\\alpha=0.26$

Hence, the value of alpha is 0.26, assuming a confidence level of 74%.

What is the correct inverse function for f(x) = e2x ?

Lena [83]

To solve this problem you must appy the proccedure shown below:

1. You have the following function given in the problem above:

f(x)=e^2x

2. You can rewrite is:

y=e^2x

3. Interchange the variables, as below:

x=e^2y

3. The inverse of an exponential function is the logarithm function. Thereforem you have:

ln(x)=ln(e^2y)
ln(x)=2y

4.Then, you have:

y=ln(x)/2

Therefore, the answer is:

f^-1(x)=ln(x)/2
