Answer:
x = 1.1
Step-by-step explanation:
x+4.6=5.7
-4.6 = -4.6
x=1.1
Step-by-step explanation:
The slope of a line characterizes the direction of a line. To find the slope, you divide the difference of the y-coordinates of 2 points on a line by the difference of the x-coordinates of those same 2 points .
Given:
Circumference of a circle = C
Diameter of a circle = d
To find:
The relationship between the circumference, c, and diameter, d, of any circle.
Solution:
We know that, circumference of a circle is
It can be written as
![[\because d=2r]](https://tex.z-dn.net/?f=%5B%5Cbecause%20d%3D2r%5D)
On dividing both sides by d, we get
Therefore, the correct option is (F).
Answer:
y ≈ 2.5
Step-by-step explanation:
Using the Sine rule in Δ XYZ
= 
, substitute values
= 
( cross- multiply )
y sin50° = 2 sin75° ( divide both sides by sin50° )
y = 
≈ 2.5 ( to the nearest tenth )
Using a calculator, it is found that for the two-tailed test of significance, the p-value is of 0.9195.
The correlation coefficient is also called <u>Pearson's r-score</u>, and is used for two-tailed tests. To find the p-value, the information needed is:
- The value of the Pearson's r-score, that is, the value of the correlation coefficients.
- The sample size.
In this problem, we have that the correlation coefficient is of r = 0.02, with a sample size of n = 28.
- Using it as the input for a r-score calculator, the p-value is of 0.9195.
