Which is what the length of the hypotenuse of the triangle ?
2 answers:
For this, you will be doing the pythagorean theorem, which is . In this case, the legs are 12 and 35 and the hypotenuse is AB. Using this, the equation will look like this:
Firstly, solve the exponents:
Next, add up 144 and 1225:
Lastly, square root each side, and your answer should be
In short, the hypotenuse is 37 ft, or the last option.

To draw the graph of linear equation of the form
y-a=m (x-b)
We will first write it in slope intercept form which is of the form
It will cut x axis and y axis at , respectively.
As Euclid postulate States that, Unique equation of line can be Determined by two points,So join these two points.And Infinite number of points lie on a line.

Answer:
We know that the p value is 0.1, and since is a left tailed test would be given by:
And we can find the calculated value using excel or the t table.
If we use the following excel code we got: "=T.INV(0.1,48)"
And the calculated value is
Step-by-step explanation:
State the null and alternative hypotheses to be tested
We need to conduct a hypothesis in order to determine if the true mean is lower than specified valu , the system of hypothesis would be:
Null hypothesis:
Alternative hypothesis:
Compute the test statistic
We don't know the population deviation, so for this case is better apply a t test to compare the actual mean to the reference value, and the statistic is given by:
(1)
t-test: "Is used to compare group means. Is one of the most common tests and is used to determine if the mean is (higher, less or not equal) to an specified value".
We can find the degrees of freedom for this test given by:
We know that the p value is 0.1, and since is a left tailed test would be given by:
And we can find the calculated value using excel or the t table.
If we use the following excel code we got: "=T.INV(0.1,48)"
And the calculated value is
