Answer:
Linear pair angle of 40 is
=180-40
=140
If, the two rays are parallel
Therefore, the two rays are parallel and the straight line is transversal
Therefore, (?) angle =140 corrosponding angle
Your answer is 140
Answer:
5
Step-by-step explanation:
6-6/7
using pemdas it's:
6/7= 0.857
6-0.857=5.143
5.143 to the nearest whole number is 5
The confidence interval at 95% level is
7106.87 < μ< 14255.27
<h3>What is meant be mean and standard deviation?</h3>
The ratio of sum of observations to the total number of observation is known as mean. It is one of the central tendency in the statistics. It gives an idea about the central value present in the data. The most sensitive measure of central tendency is mean. It is very easy to calculate. Mean playa a crucial role in daily life. The two types of means are Arithmetic mean and Geometric mean.
Standard deviation is a measure in the statistics. The amount of variation of a set of values is known as standard deviation. Standard deviation is denoted by σ.
As per given data
90% confident level for amount of electricity used in community of Austin is
X-tx/2(n-1)s/√n < μ < X+ tx/2(n-1)s/√n
Here , n=12 , X=10681.07 , s=6893.87
Margin of error = tx/2(n-1)s/√n
=(1.796×6893.87)/√12
=3574.1996
=3574.19(approximately)
Therefore, 90% CI is,
10681.07-3574.19 ≤ μ<10681.07+3574.19
7106.87 < μ< 14255.27

Answer:
the answer is D.
Step-by-step explanation:
The given two polygons are similar to one another ~
Sides of the given polygons are in ratio of :
to put in simple Ratio ~
So, the sides of the larger polygon are :
Now, to find the Perimeter of larger polygon ~ add the side length of all sides :
