Answer:
We conclude that he used a paired two-sample t-test.
Step-by-step explanation:
We know that the student measuring how gasoline prices change records the cost of gas at 10 randomly selected stations in her hometown. One week later, she records the price again at the same 10 stations.
We conclude that he used a paired two-sample t-test.
Because at each gas station, the student measured the price of gas twice.
The value of diameter for the given triangle inscribed in a circle will be 22.
<h3>What is a circle?</h3>
A circle is a geometrical figure which becomes by plotting a point around a fixed point by keeping a constant distance.
In our daily life, we always see circular objects for example our bike wheel.
The longest line which can be drawn inside the circle will be the diameter.
As per the given triangle inscribed a circle.
The length x +2 and 2x - 7 will be the radius of the circle and the sides of the triangle will be the tangent of the circle.
x + 2 = 2x - 7
2 = 2x - x - 7
x = 9
Thus, radius = 9 + 2 = 11
Diameter = 11 x 2 = 22 units.
Hence "The value of diameter for the given triangle inscribed in a circle will be 22".
