4+8+(5X7)+5(7-9)=6+B
USE PEMDAS
5X7=35
4+8+35+5(7-9)=6+B
(7-9)=-2
4+8+35+5(-2)=6+B
5X-2=-10
4+8+35+-10=6+B
4+8+35+-10=37
minus both sides by 6
37-6=31
6+B-6=B
31=B or B=31
Answer:
C, 40 degrees
Step-by-step explanation:
All the angles of a triangle add to 180 degrees according to the Triangle Sum Theorem.
Since all angles sum to 180, we can set all the values to add to 180.
We have:
Combining like terms, we have:
Subtracting 60 from both sides gets us
Dividing by 3 from both sides equals
Answer:
The answer is below
Step-by-step explanation:
Given that:
Mean (μ) = 1.93, standard deviation (σ) = 1.08 pounds, sample (n) = 62.
the mean weight of discarded plastic for all household is given by:
The standard deviation of discarded plastic for all household is given by:
The confidence (c) = 90% = 0.9
α = 1 - c = 1 - 0.9 = 0.1
α/2= 0.1/2 = 0.05
The z score of 0.05 corresponds to the z score of 0.45 (0.5 - 0.05) which is 1.645. i.e.
The margin of error (E) =
The confidence interval =
We are 90% confidence that the value is between 1,7044 and 2.1556
