Answer:
The length of x in the simplest radical form with a rational denominator will be:
Step-by-step explanation:
Given
hypotenuse = 5
angle Ф = 60°
To determine
x = ?
Using the trigonometric ratio
cos Ф = adjacent / hypotenuse
here
Ф = 60°
adjacent of 60° = x
hypotenuse = 5
so substituting Ф = 60°, adjacent = x and hypotenuse = 5 in the equation
cos Ф = adjacent / hypotenuse
so


switch sides

Multiply both sides by 5

Simplify

Therefore, the length of x in the simplest radical form with a rational denominator will be:
Answer:
the P value is 45.22%
Step-by-step explanation:
The computation of the P value is as follows;
Given that
standard deviation = 14.9
mean = 675
Reduction in diameter= 673.2
Based on the above information,
We have to applied the following formula i.e.

Now the P value for -0.1208 is 0.4522 i.e. 45.22%
Hence, the P value is 45.22%
The same is to be considered
