The real answer is y=-1/2+9 !
<span>First step is find total height of all the figures expressed in feet:
Liem: 6 ft 2 inch = 6,167 ft
Eli: 5 ft 9 inch = 5,75 ft
Faith 6 ft
Simon: 5 ft 4 inch = 5,34 ft
To calculate the total height we need to know that 12 inches are 1 foot
6’2”+5’9”+6+5’4”= 22 ft 15 inch = 23 ft 3 inch
Another way is by adding decimal figurel:
6,167 + 5,75 + 6 + 5,34 = 23,25 feet
Then we know that 3 feet are 1 yard, so then total height is:
23,25 / 3 = 7,75 yards</span>
Answer:
The 95% confidence interval = (98.225, 98.655)
Step-by-step explanation:
The formula for Confidence Interval =
Mean ± z × standard deviation/√n
Where Mean = 98.44°F
Standard deviation = 0.30°F
n = number of samples is 10
Because our number if samples is small, we use the t score confidence interval formula
Mean ± t × standard deviation/√n
Degrees of Freedom = n - 1
= 10 - 1 = 9
We find the t score of 95% confidence interval and degrees of freedom 9
= 2.262
Hence,
Confidence interval = 98.44 ± 2.262 × 0.30/√10
= 98.44 ± 0.214592162
Confidence Interval
98.44 - 0.214592162
= 98.225407838
≈ 98.225
98.44 + 0.214592162
= 98.654592162
≈ 98.655
The 95% confidence interval = (98.225, 98.655)
<em>Answer : </em><em>15 days</em>

<em>Explanation?</em>
<em>Well considering it takes them 3 days to make 8, we would divide 40 by 8 which is 5 and multiply 3 and 5 to get 15 days in total.</em>
