Answer:
(0.4062, 0.5098)
Step-by-step explanation:
In a sample with a number n of people surveyed with a probability of a success of 
, and a confidence interval 
, we have the following confidence interval of proportions.
In which
Z is the zscore that has a pvalue of 
For this problem, we have that:
356 dies were examined by an inspection probe and 163 of these passed the probe. This means that 
and 
Assuming a stable process, calculate a 95% (two-sided) confidence interval for the proportion of all dies that pass the probe.
So 
= 0.05, z is the value of Z that has a pvalue of ![1 - \frac{0.05}{2} = 0.975[tex], so [tex]z = 1.96](https://tex.z-dn.net/?f=1%20-%20%5Cfrac%7B0.05%7D%7B2%7D%20%3D%200.975%5Btex%5D%2C%20so%20%5Btex%5Dz%20%3D%201.96)
.
The lower limit of this interval is:
The upper limit of this interval is:
The correct answer is
(0.4062, 0.5098)
Answer:
x = -4 ;
Step-by-step explanation:
6(x+3)=2(2x+5)
Distribution
6x+18 = 4x + 10
Subtract 4x on both sides
2x+18 = 10
Subtract 18 on both sides
2x = -8
Divided by 2
x = -4
Now if we have to substitute the value of X
6(-4+3)=2(-8+5)
Parenthesis first
6(-1) = 2(-3)
-6 = -6
Answer:
The logarithmic function modeled by the given table:
f(x) = log₃x
Step-by-step explanation:
Given Table:
x f(x)
9 2
27 3
81 4
We can see that x increases as powers of 3. And f(x) is the power.
We assume that f(x) = log₃x
Checking using the table:
for x = 9
f(x) = log₃9 = 2
for x = 27
f(x) = log₃27 = 3
for x = 81
f(x) = log₃81 = 4
Hence proved.
