Answer:
95% CI = ( 8.024 , 8.936 )
Step-by-step explanation:
Developing the exercise for a normal distribution then we have to calculate the degrees of freedom,
Where n, is our sample.
So in the table,
t = 2.1604
<em>**Assumptions:</em>
<em>Population is normal distributed</em>
Answer:
≈ 83.9 cm²
Step-by-step explanation:
<u>Given:</u>
- P = a+b+c = 44 cm
- a = 18 cm
- b = 12 cm
<u>Then:</u>
- c= P -(a+b) = 44 -(18+12) = 14 cm
<u>Area of the triangle is found by using Herons formula:</u>
where s = P/2 = 44/2 = 22 cm
- A = √22(22-18)(22-12)(22-14) = √22*4*10*8= √7040 ≈ 83.9 cm²

Hey I dont know how to graph it but the answer is a > 8. Hope this helps
Step-by-step explanation:
In order for us to easily answer this problem, let us make the units uniform. So 1 kiloliter is equivalent to 10 hectoliters. This would mean that 11 kiloliters is 110 hectoliters. Since 40 hectoliters is for making ice cream, only 70 hectoliters of milk is left to be used in other ways. Hope this answers your question. Have a great day!
Answer: 1 (-4)
Step-by-step explanation: f(x) is a function of x giving you a y value. 1/2 f(x) means you're halving every y value that plugging in x gives you.
