Because all three of these are 7.68x10^a power the determining factor in which one is the greatest is based on which one has the largest exponent -3<3<7 so this is the order from least to greatest.
(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.

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].

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.

house has increased in value by 35% since it was purchased. If the current value is $567,000, what was the value when it was purchased?
9514 1404 393
Answer:
$420,000
Step-by-step explanation:
If we say the current value (v) is 35% more than the purchase price (p), then we have ...
v = p + 0.35·p
567,000 = 1.35p
Dividing by the coefficient of p, we get ...
p = 567,000/1.35 = 420,000
The value when it was purchased was $420,000.
The width of a rectangle is 70% of its length. What is the area of the rectangle?
Answer:
the area is 130
Step-by-step explanation:
The area of the rectangle for the given case is obtained as 0.7x².
What is a Linear equation?A linear equation is a equation that has degree as one.To find the solution of n unknown quantities n number of equations with n number of variables are required. A linear equation can be solved by doing operations with the same number on both sides of the equation.
Suppose the length of the rectangle be x.
Then, its width is given as 70% × x = 0.7x.
Since, the area of the rectangle is the product of length and width, the following equation can be written as,
x × 0.7x = 0.7x².
Hence, the required expression for the area of the rectangle is given as 0.7x².
