5) Obtuse triangle because the top angle is more than 90 degrees
Answer:
length=4 1/4
Step-by-step explanation:
- 1 3/4 + 2 1/2
- convert 2 1/2 into 2/4 since 2 is half of 4
- add the converted number and 1 3/4 fractions
- 2/4 and 3/4 added will make 1 1/4
- add 1 1/4, 2 and 1 and it will equal 4 1/4
3x (4x^4-5x)
add all of the numbers with a x to get
12x^4
and 12x^4=
20736x
Answer:
substitute that value for x in the polynomial and see if it evaluates to zero
Step-by-step explanation:
A "zero" of a polynomial is a value of the polynomial's variable that make the expression become zero when it is evaluated. As an almost trivial example, consider the polynomial x-3. The value x = 3 is a zero because substituting that value for x makes the expression evaluate as zero.
3 -3 = 0
___
Evaluating polynomials can be done different ways. Straight substitution for the variable is one way. Using synthetic division by x-a (where "a" is the value of interest) is another way. This latter method is completely equivalent to rewriting the polynomial to Horner form for evaluation.

In the attachment, Horner Form is shown at the bottom.
The measure represents the standard deviation of the sample means and is used in place of the population standard deviation when the population parameters are unknown is; t-test.
<h3>Which measure is used when the population parameters are unknown?</h3>
A hypothesis test for a population mean when In the case that the population standard deviation, σ, is unknown, carrying out a hypothesis test for the population mean is done in similarly like the population standard deviation is known. A major distinctive property is that unlike the standard normal distribution, the t-test is invoked.
