It is a negative graph and if you take the peak- the y intercept, it gives you the value of b. make that value negative and you should get your answer. i also put my answer in the comments if you wanted it, but you said you didn’t so..
Answer: (97.63, 99.77)
Step-by-step explanation:
Given the data:
99.6 99.7 97.9 98.6 97.7
Using calculator, we can obtain the mean and standard deviation of the sample data:
Mean(m) = 98.7
Standard deviation = 0.93
Sample size (n) = 5
Using the relation to find confidence interval :
Mean ± Zcrit * (s/√n)
Zcrit at 99% = 2.576
98.7 ± 2.576 * (0.93 / √5)
Lower limit : 98.7 - (2.576 * 0.4159086) = 97.6286194464 = 97.63 ( 1 decimal place)
Upper limit : 98.7 + (2.576 * 0.4159086) = 99.7713805536 = 99.77 ( 1 decimal place)
(97.6, 99.8)
Step-by-step explanation:
The area of a triangle equals 1/2*base of triangle*height of triangle. Think about when you're finding the area of a square, you multiply the base times its height. A triangle is half of a square so then you just multiply it by 1/2.
