A system of equations is graphed on the coordinate plane. 2y=3x−14y=6x−2 Select the number of solutions for the system of equati
1 answer:
The pair of the linear system has a unique solution. Then the number of solutions is exactly one.
<h3>What is the linear system?</h3>It is a system of an equation in which the highest degree of the variable is always 1. A one-dimension figure that has no width. It is a combination of infinite points side by side.
Given
The equations are 2y = 3x - 14 and y = 6x - 2.
We know the condition.
The system of equations follows the condition.
The graph is shown below.
Since the pair of the linear system has a unique solution.
Thus, the number of solutions is exactly one.

Answer:
<u>Step-by-step explanation:</u>
Note the following identities: tan² x = sec²x - 1
tan² x + sec x = 1
(sec² x -1) + sec x = 1
sec² x + sec x - 2 = 0
(sec x + 2)(sec x - 1) = 0
sec x + 2 = 0 sec x - 1 = 0
sec x = -2 sec x = 1
Answer:
The test statistic is t = 3.36.
Step-by-step explanation:
You're testing the claim that the mean difference is greater than 0.7.
At the null hypothesis, we test if the mean difference is of 0.7 or less, that is:
At the alternate hypothesis, we test if the mean difference is greater than 0.7, that is:
The test statistic is:
In which X is the sample mean, is the value tested at the null hypothesis, s is the standard deviation of the sample and n is the size of the sample.
0.7 is tested at the null hypothesis:
This means that
A survey of 35 people was conducted to compare their self-reported height to their actual height.
This means that
From the sample, the mean difference was 0.95, with a standard deviation of 0.44.
This means that
Calculate the test statistic
The test statistic is t = 3.36.
By taking <span>logarithmic of base 10
