Answer:
72 degrees
Step-by-step explanation:
Because you want subtract both of the number from 180 because triangles angles always have to equal 180 degrees. I hope that helped! :)
10 is twice the size of 5 thus 100% bigger
Answer:h=-2
Step-by-step explanation:
Equation:h(-6) = |2(-6) +1| +1
Step 1: Simplify
=-6h=12
Step 2:Divide both sides of the equation by -6
-6h/-6=12/-6
h=-2
Answer:
B is Geometric and its next terms are 81, 243, 729...
See example below to complete other problems.
Step-by-step explanation:
Geometric sequences have a pattern that is exponential. Because of this, they do not have a constant rate of change using addition or subtraction. Instead, they have a constant rate through multiplication and division called a common ratio. Problem B is geometric because as you subtract each y value you get a different value each time. It is not a common difference. But if you divide, you find a common ratio.
Example: 27-9= 18 27/9 = 3
9-3 = 6 9/3 = 3
etc. Common ratio of 3
Answer:
The observed value of the chi-square statistic is 34.71
Step-by-step explanation:
Given the data in the question';
Calculate the observed value of the chi-square statistic
The chi-square statistic will be;
∑
[ ( O - E)² / E ]
here O is observed frequency of th class
E is expected frequency of th class
= 1, 2 which denote the class of food experts who guess correctly and who didn't guess correctly
so
∈ = n × probability of not guessing correctly = 168 × 2/3 = 112
∈1 = n × probability of guessing correctly 168 × 1/3 = 56
so
∑[ ( O - E)² / E ] = [ ( 92 - 56)² / 56 ] + [ ( 76 - 112)² / 112 ]
= 1296/56 + 1296/112
= 23.14 + 11.57
= 34.71
Therefore, the observed value of the chi-square statistic is 34.71
