Hope this helped.
Type it into the app or online on ‘Desmos’ it a really good graphing calculator. I hope this helps
Step by Step:
Distribute:
=5+(−3)(x)+(−3)(2)
=5+−3x+−6
Combine Like Terms:
=5+−3x+−6
=(−3x)+(5+−6)
=−3x+−1
Answer: =−3x−1

Answer:
Step-by-step explanation:
Data given and notation
n=530 represent the random sample taken
X=139 represent the yellow pods in the random sample
estimated proportion of yellow pods
is the value that we want to test
represent the significance level
z would represent the statistic (variable of interest)
represent the p value (variable of interest)
Concepts and formulas to use
We need to conduct a hypothesis in order to test the claim that the true proportion is 0.25 or 25%:
Null hypothesis:
Alternative hypothesis:
When we conduct a proportion test we need to use the z statistic, and the is given by:
(1)
The One-Sample Proportion Test is used to assess whether a population proportion
is significantly different from a hypothesized value
.
Calculate the statistic
Since we have all the info requires we can replace in formula (1) like this:
Then second integer is n+2 <--------
n + n + 2 = 24
2n = 22
n = 11
