Answer: x = 2
Step-by-step explanation: the interior angles of a rhombus add to 360 degrees and since half of 360 is 180, create the equation 130 + (36 +7x) and set it equal to 180. when solved 130 + (36 +7x) = 180 you get x =2
Answer:
Step-by-step explanation:
CABD is half-circle as CD is diameter and cuts the circle in half
- CABD = CA + AB + BD
- 180° = x + 70° + x
- 110° = 2x
- x = 110°/2
- x = 55°
Correct choice is d)
I thought to say the second sentence because it says that he’s going at a different constant speed but he doesn’t say compared to who... I’m leaning more to the last sentence.

Answer:
198 is the variance for the number of defective parts made each week.
Step-by-step explanation:
We are given the following in the question:
Number of parts produced each week = 20,000
Percentage of defective parts = 1%
We have to calculate the variance for the number of defective parts made each week.
We treat defective part as a success.
P(Defective part) = 1% = 0.01

Then the number defective parts follows a binomial distribution
.
Formula for variance =

Thus, 198 is the variance for the number of defective parts made each week.
