Answer:
The water falls a total length of 2,425 feet
Step-by-step explanation:
In order to calculate the total length of the waterfall, we will find the sum of the three parts of the waterfall.
Length of upper fall = 1430 feet
Length of middle cascade = 675 feet
Length of lowe fall = 320 feet
Total length of fall = (Length of upper fall) + (Length of middle cascade) + (Length of lowe fall)
= 1430 + 675 + 320 = 2,425 feet
Total length that the water falls = 2,425 feet
Answer: c. 39.14 to 42.36
Step-by-step explanation:
We want to determine a 95% confidence interval for the average hourly wage (in $) of all information system managers
Number of sample, n = 75
Mean, u = $40.75
Standard deviation, s = $7.00
For a confidence level of 95%, the corresponding z value is 1.96. This is determined from the normal distribution table.
We will apply the formula
Confidence interval
= mean +/- z ×standard deviation/√n
It becomes
40.75 +/- 1.96 × 7/√75
= 40.75 ± 1.96 × 0.82
= 40.75 + 1.6072
The lower end of the confidence interval is 40.75 - 1.6072 =39.14
The upper end of the confidence interval is 40.75 + 1.6072 =42.36
Answer:
A negative number
Step-by-step explanation:
example: (-1) *( +1)= -1
(2/7)m - (1/7) = 3/14
2m/7 =(3/14) + (1/7)
2m/7 = (3/14) + 2(1/7)
here we are multiplying 2 with 1/7 to make the denominator same for addition.
2m/7 = (3/14) +(2/14)
2m/7 = (3 + 2)/14
2m/7 = 5/14
2m = (5 *7)/14
2m = 35/14
2m = 5/2
m = 5/4
m = 1.25
So the value of "m" is 1.25
Answer:
I think the answer is 2. Hope this helps!
