First calm down listen to the steps
1. Since there are 4 triangle so you will need to find the area and the formula is base(height)1/2 but you should probably check the formula just to make sure
2.Then you will find the area of the square which is length times width
3.Add all 5 areas together and the answer should be labeled in squared
hope that helped
Answer:
The answer is below
Step-by-step explanation:
Given that mean (μ) = 266 days, standard deviation (σ) = 16 days, sample size (n) = 16 women.
a) The mean of the sampling distribution of Xbar () is given as:
The standard deviation of the sampling distribution of Xbar () is given as:
b) The z score is a measure in statistics used to determine by how much the raw score is above or below the mean. It is given by:
For x > 270 days:
The probability the average pregnancy length exceed 270 days = P(x > 270) = P(z > 1) = 1 - P(z < 1) = 1 - 0.8413 = 0.1587 = 15.87%
Answer:
x = 26
Step-by-step explanation:
The parallel lines are Line l and Line m. The other line shown is the transversal.
When 2 parallel lines are cut by a trasversal it creates 4 euqual angles and another 4 equal angles of different measure.
The angle "5x + 7" is equal to the angle "8x - 71" since they are <em><u>alternate exterior angles.</u></em>
<em><u /></em>
So, we can equate both expressions and use algebra to solve for "x". The process is shown below:
Hence,
the value of x is 26
