Answer:
<em>hello your question lacks some information attached below is the complete question</em>
answer : NO
Step-by-step explanation:
Determine the probability of not selecting an obese subject in 3 trials
= P ( not obese in 3 randomly selected ) = ( 1 - 0.111 )^3
= 0.703
The probability > 0.05
hence it is insignificant therefore the answer is NO
Your answer is 75°.
To answer this question you need to use both the cosine rule and the sine rule. First, we need to find the length of side b by using the cosine rule, where a = 2 and c = √3 + 1. Then you substitute these into the equation:
b² = a² + c² - 2×a×c×cos(B)
b² = (2)² + (√3 + 1)² - 2×2×(√3 + 1)×cos(60)
b² = 4 + 4 + 2√3 - (4 - 4√3)×0.5
b² = 8 - 2 = 6
b = √6
Then you use this length in the sine rule, and find the angle:

sin(A) = (√6 + √2)/4
A = 75

Step-by-step explanation:
We have the equation:

And we want to show that:

Instead of differentiating directly, we can first square both sides:

We can find the first derivative through implicit differentiation:

Hence:

And we can find the second derivative by using the quotient rule:

Substitute:

Answer:
125
Step-by-step explanation:
By doing 6.99/87, we can figure out that each chip costs approximately 8 cents. With this in mind, we can divide 10 by 0.08 to get 125.
