Melanie can travel 374 miles on 11 gallons. This is because when you divide 306 by 9 you get 34 so u multiply 34 by 11 and you get 374.
Answer:
The maximal margin of error associated with a 95% confidence interval for the true population mean is 2.238.
Step-by-step explanation:
We have given,
The sample size n=42
The sample mean
The population standard deviation
Let be the level of significance = 0.05
Using the z-distribution table,
The critical value at 5% level of significance and two tailed z-distribution is
The value of margin of error is
The maximal margin of error associated with a 95% confidence interval for the true population mean is 2.238.
Let's break down all the information we receive from the question.
One pair of shoes= three times as much as a scarf
One pair of shoes and one scarf= $32
We need to make an equation where 3s= pair of shoes and s=scarf. We then need to put one pair of shoes + one scarf = 32.
3s+s=32
Now add.
4s=32
You could use 4s=32 (or 32÷4=s).
Answer:
x + x / 2 = -7 + -2 / 2 = -4.5
