The answer is actually 80 degrees, I just took the test.
Answer:
The angles are <u>155°</u> and <u>25°</u>.
Step-by-step explanation:
Given:
Two supplementary angles are in the ratio of 31:5.
Now, to find the angles.
The sum of two supplementary angles = 180°
Let the ratio of the angles be .
So, according to question:
<em>Dividing both sides by 36 we get:</em>
So,
And,
Therefore, the angles are 155° and 25°.
Answer:
The sample size is
Step-by-step explanation:
From the question we are told that
The margin of error is E =4.266
The standard deviation is
From the question we are told the confidence level is 99% , hence the level of significance is
=>
Generally from the normal distribution table the critical value of is
Generally the sample size is mathematically represented as
=>
=>
Answer:
Rises to the left and rises to the right.
Step-by-step explanation:
Since, the given function is f(x)=, and the end behavior of the given function is determined as:
Consider the given function f(x)=, identify the degree of the function:
The degree of the function is : 4 which is even
And then identify the leading coefficient of the given function that is +2 which is positive in nature.
Hence, the function is positive and even in nature, therefore, the end behavior of the function will be rising to the left and rising to the right.
