<h2>The required value of x is equal to 2.</h2>
Step-by-step explanation:
We have,
To find, the value of x in the given equation = ?
∴
By crossmultiplication, we get
3(3x) = x + 16
⇒ 9x = x + 16
⇒ 9x - x = 16
⇒ 8x = 16
⇒ x =
⇒ x = 2
∴ The value of x = 2
Thus, the required value of x is equal to 2.
Answer:
The appropriate answer is "0.0124".
Step-by-step explanation:
Given:
Test statistics,
z = 2.5
By using the z-table,
p value for one tailed test will be:
= 0.0062
For two-tailed test,
⇒
Shown below
<h2>Explanation:</h2>In this exercise, we have the following system of linear equations in two variables:
From the first equation:
Here as x increases one unit, then y decreases by one unit too. Therefore, if (0, 5) is a point on the line, then (1, 4) is also a point on the line. From here, we know that the line must pass through these two points.
From the second equation:
Here as x increases 4 units, then y increases by one unit Therefore, if (0, 10) is a point on the line, then (4,11) is also a point on the line. From here, we know that the line must pass through these two points.
By using graphing tool, we realize that both graphs intersect at a single point, which is:
The graph is shown below.
