(a) Find a 90% confidence interval for the population mean price (per 100 pounds) that farmers in this region get for their watermelon crop (in dollars). What is the margin of error (in dollars)
Answer:
The margin of error (E) [tex]=0.49[/tex]
Step-by-step explanation:
Given,
mean [tex]\bar{x}=6.88[/tex]
standard deviation [tex]\sigma=1.90[/tex]
sample size [tex]n=41[/tex]
[tex]90\% \quad \text{confidence interval}[/tex]
Critical value [tex]=\frac{z_\alpha}{2}\quad \quad\quad[\because\;\alpha=1-\text{confidence interval}][/tex]
[tex]=1-0.90[/tex]
[tex]\Rightarrow \alpha=0.1[/tex]
Critical value [tex]=\frac{z_{0.1}}{2}[/tex]
[tex]=z_{0.05}[/tex]
[tex]=1.645[/tex]
The margin of error (E) [tex]=\frac{z_\alpha}{2} \times\frac{\sigma}{\sqrt{n} }[/tex]
[tex]=1.645\times\frac{1.90}{\sqrt{41} }[/tex]
[tex]=0.49[/tex]
Hence, The margin of error (E) [tex]=0.49[/tex]

People get energy from the food they eat. This energy is measured in calories. When you exercise, you use up or burn calories. The picture at the right shows about how many calories a 125-pound person burns each minute bowling. How many calories does a 125-pound person burn in 2 hours of bowling? 3 calorie burned each minute
Answer:
360
Step-by-step explanation:
There are 60 minutes in 1 hour, so 2 hours = 120 minutes.
Multiply 120 by 3 and you get 360.
They would burn 360 calories doing 2 hours of bowling.

The shop stocks 3 times as many Coca-Colas as Coke Zeros. There are a total of 36 on the shelf. How many of each type of drink are there?
Please explain thank youu!
Answer
There are 12 coke zeros and 24 coca-colas
Step-by-step explanation:
If there are 36 drinks in total and the shop stocks 3 times as many cokes than coke zeros you would have to divide 36 by 3 and that gets you 12 coke zeros and to check your work you can do 12 times 3 which would be 3 times the cokes which makes a total of 36 and 36 - 12 = 24 cokes.

f(x) = -2² – 3x + 3
Find f (7)
Answer:
[tex]f(7) = -22 \\[/tex]
Step-by-step explanation:
Whenever there is a question asking to find something like f(7), it is asking you to substitute the number within those parentheses for the matching variable within the function.
To find f(7), first substitute 7 for all the x's within the function. Then, following PEMDAS, simplify like how you normally would. Multiply out [tex]-2^2[/tex], then multiply 3 by 7, then add all the numbers together.
[tex]\\f(7) = -2^2-3(7)+3\\f(7) = -4 - 21 + 3\\f(7) = -25 + 3\\f(7) = -22[/tex]
Thus, [tex]f(7) = -22 \\[/tex].
