Answer:
Total earning is $106
Explanation:
Step-by-step explanation:
Odd number between greater than 1 to less than 9 is 3,5,7
Common number which is divisible by 3,5,7.
we add 1 in 105
105 + 1 = 106
Devide 106 by 3 ,5 ,7 get remainder 1
Then
Devide 106 by even number (greater than 1 and less than 9 )
We can't get remainder as 1
So the answer is $106
Answer:
y = 2
Step-by-step explanation:
The maximum of this function is 5 and the min. is -1. Thus, the range is [-1, 5]. The midpoint of this range is the y-value of the midline:
-1 + 5
--------- = 2
2
Thus, the equation of the midline is y = 2.
Answer: 49.44807
Round that however you need to. Unfortunately the rounding instructions on the screenshot are cut off, so I cannot see what that part says.
=======================================================
Work Shown:
sin(angle) = opposite/hypotenuse
sin(22) = h/132
h = 132*sin(22)
h = 49.44807
Using the t-distribution, it is found that:
a. The <u>margin of error</u> is of 4.7 homes.
b. The 98% confidence interval for the population mean is (19.3, 28.7).
The information given in the text is:
- Sample mean of .
- Sample standard deviation of .
- Sample size of .
We are given the <u>standard deviation for the sample</u>, which is why the t-distribution is used to solve this question.
The confidence interval is:
The margin of error is:
Item a:
The critical value, using a t-distribution calculator, for a two-tailed <u>98% confidence interval</u>, with 23 - 1 = <u>22 df</u>, is t = 2.508.
Then, the <em>margin of error</em> is:
Item b:
The interval is:
The 98% confidence interval for the population mean is (19.3, 28.7).
