Answer:
Step-by-step explanation:
Given data:
standard deviation is 
As distribution is normal in shape and values are symmetrical
The standard deviation rule says that 95% of observation lies between the second standard deviation of the mean
so, approximately only 5% of observation lies outside the interval and normal shape is symmetric. hence approximately 0.15% of observation lies above the interval
almost 0.15% of students spent more amount is 529
A linear pair means that the sum of the angles is 180
degrees.
Therefore:
a + b = 180°
We know that:
a = b + 26°
Therefore:
b + 26 + b = 180
2b = 154
b = 77°
So,
a = b + 26 = 103<span>°</span>
The statements that I agree with, with respect to a parallelogram are:
- A parallelogram has six sides.
- Opposite sides of a parallelogram are parallel.
- All angles of a parallelogram have the same measure.
- All sides of a parallelogram have the same length.
<h3>What is a
parallelogram?</h3>
A parallelogram can be described as the quadrilateral that do contains two pairs with respect to their parallel sides.
It should be noted that the sides that can be found in the parallelogram are usually of the same length and there the sides that can be attributed to a parallelogram is usually 6.
Therefore, the option 1,2,4,5 are correct.
