e someone help me.
Solve for X.
1) (2x+1/3)=2x
2)Jeydas soccer team sells T-Shirts to raise money for new equipment. For each T-Shirt sold, the team raises $8. Parents also make a donation of $100 toward equipment. What is the equation that represents the total amount raised,y, if x-T shirts are sold?
3)Mercury is the closest planet to the Sun at a distance of 36 million miles.The closest star to the sun is Próxima Centauri, which is 4.24 light years away. A light year is 5.9*10^12 miles.
Part A) Write the distance in miles form mercury to the sun in scientific notation.
Part B) How many miles from the sun is Proxima Centaurl? Express your answer in Scientific notation.
Part C) About how many times greater is the distance from the sun to proxima centaurl compared to the distance from the sun to mercury? Express your answer in scientific notation.

Answer:
Assuming a standard significance level of the best conclusion for this case would be:
4. There is not enough evidence to show that more than 35% of community college students own a smart phone (P-value = 0.034).
Because
If we select a significance level lower than 0.034 then the conclusion would change.
Step-by-step explanation:
Data given
n=300 represent the random sample taken
X=120 represent the people who have a smart phone
estimated proportion of people who have a smart phone
is the value that we want to test
z would represent the statistic (variable of interest)
represent the p value (variable of interest)
System of hypothesis
We need to conduct a hypothesis in order to test the claim that the true proportion of people who have a smart phone is higher than 0.35, the system of hypothesis are.:
Null hypothesis:
Alternative hypothesis:
The statistic is given by:
(1)
Calculate the statistic
Since we have all the info requires we can replace in formula (1) like this:
Statistical decision
Since is a right tailed test the p value would be:
