Answer:
Null Hypothesis: p = 0.65.
Step-by-step explanation:
The null hypothesis is the expected population population, from an assumption deriving for example, from a previous experiment.
According to a researcher who was quoted in a New York Times article in March, 2011, 65% of U.S. community college students must take at least one remedial course in English
This means that the expected value of the population proportion is , which is the null hypothesis.
Null Hypothesis: p = 0.65.
1) Change the word problem into an equation:
.5x+x=213.75 where x equal the amount of money Dave earns.
2) Combine the like terms: .5x+x=1.5x
3) Now solve: 1.5x=213.75 and use multiplicative inverse to get your answer of 142.5
4) Now wait, this is the amount Dave earns not the amount Monsiha earns, however we know that Monsiha earns half that, therefore:
142.5÷2=75.25
The answer would be 'Monsiha raised $75.25 in total'.

Answer:
95 seconds
Step-by-step explanation:
At 5 seconds per box, pulling 3 boxes takes 3×5 = 15 seconds.
At 1 second per envelope, pulling 10+10+60 = 80 envelopes takes 1×80 = 80 seconds.
The total time required to provide the required envelopes is 15 +80 = 95 seconds.
Answer:
$3h+$2h=T
Step-by-step explanation:
Since we don't know how many hot dogs(h) or hamburgers(h) they will buy, you just need to use the variables and multiply by how much each one costs and then add them to get the Total (T).
45 cents will be 8.1 percent of 18 dollars
