Answer:
The perimeter of this rectangle is 14x + 10
Step-by-step explanation:
You want to add all of the sides together.
First, you add 4x-2 and 3x+7
4x-2 + 3x+7 = 7x+5
Then, you multiply this answer by two, since there are two of each side with each value.
(7x+5) * 2
7x * 2 = 14x
5*2 = 10
So, (7x+5) * 2 = 14x + 10
14x + 10 is your final answer
Answer:
Based on statistical analysis the claim is of 3% of patients developing adverse reaction is valid and there is a drug problem
Step-by-step explanation:
Here we have
Percentage of patients that develop nausea em= 153/5783 *100 = 2.65 %
To test the hypothesis, we put our null hypothesis as
H₀: μ = 3%
Alternative hypothesis is then
Hₐ: μ < 3%
Therefore the test statistic is
P₀ = 0.03
= 0.0265
n = 5783
From the above we have our test statistic as -1.579 from which gives our p value as P = 0.057.
Therefore, as we have our P value less than the confidence level of 0.05, we therefore fail to reject the null hypothesis because there is sufficient statistical evidence that suggest that the proportion of patients who would have adverse reaction to the drug = 3%.

<h3>Factoring</h3>
In math, factoring or factorization is used to write an algebraic expression in factors. There are some rules for factorization. One of them is a factor out a common term for example: x²-x= x(x-1), where x is a common term.
Here you should factor the given expression.
Firstly, you should replace the variables A, B and C for the given expressions.
After that, you should find the least common multiple.
Finally, you can simplify the expression
Firstly, you should replace the variables P, Q and R for the given expressions.
