What is the rational roots of 4x^3+9x^2-x+10=0
9514 1404 393
Answer:
±1/4, ±1/2, ±1, ±5/4, ±2, ±5/2, ±5, ±10
Step-by-step explanation:
The rational root theorem tells you possible rational roots of this equation would be ...
±(divisor of 10)/(divisor of 4)
The divisors of 10 are 1, 2, 5, 10. The divisors of 4 are 1, 2, 4. Then the possible rational roots are ...
±1/4, ±1/2, ±1, ±5/4, ±2, ±5/2, ±5, ±10

This particular cubic has one irrational real root near -2.689. It has no rational roots.
Which equation represents a line which is parallel to the line Y= 1/2 X +3 1. y-2x=-5 2. 2x+y=-6 3. x-2y=2 4. x+2y=4
Answer:
x-2y=2.
Step-by-step explanation:
1) if to re-write all the given equations of the lines, then
y=2x-5; y=-2x-6; y=1/2x-1; y= -1/2x+4.
2) y=1/2x-1 only is parallel to the given y=1/2x+3.

A friend asked you to borrow $250 and agrees to repay it with 4% interest how much interest will you earn after eight months
Answer:
I believe in the question it only states 4% interest without any time factor so therefore it would be $10 interest for 1 month or 8 months

There are only 6 blue pens, 5 green pens and 8 red pens in a box.
One pen is taken at random from the box.
Write down the probability that this pen is blue.
Answer:
0.316
Step-by-step explanation:
Probability = (number of outcomes)/(total number of outcomes)
In this case,
the total number of outcomes is 6+5+8 = 19, and
the number of outcomes for getting a blue pen = 6
Hence,
P(blue) = 6/19 = 0.31578947368 ≈ 0.316

The directions on a sewing pattern say to cut an extra 15% of fabric to account for error.
Chloe needs 0.75 yardof fabric to make a skirt, and she cuts 0.1125 yard.
Did Chloe cut the correct amount of fabric? Why or why not?
9514 1404 393
Answer:
no; the yardage should be more than 0.75 yards
Step-by-step explanation:
A value that is 15% more than 0.75 will be a number that is greater than 0.75. The number 0.1125 is much less than 0.75, so cannot be the correct amount of fabric.
Chloe did not cut the correct amount.
(the correct amount is 0.8625 yards)
_____
Additional comment
Often, all that is needed for answering a multiple choice question properly is ...
a) an understanding of what the question is asking
b) comprehension of what the answer must look like.
Here, the directions are saying to cut more than 0.75 yards. The result will be a value that is more than 0.75 (and less than 1).
The value 0.1125 yard is 15% of 0.75 yard. The cut amount should be that much in addition to 0.75 yard: 0.75 +0.1125 = 0.8625 yard.

when you have the two points of a line (-4,5) and (0,6) then you use the m = (y2-y1)/(x2-x1) and you get m = 1/4
1. A senator is thinking about running for president. But she will only do so if more than 60% of the voters view her favorably. She gathers some data to see if she has this level of support. Which statistical method would be best for her to use?
The senator is faced with the making a decision to run for President, based
on the conclusion she can make from the data she gathers.
The statistical method that would be best for her to use is inferential
statistic method such as finding the percentage of supporters she has to a
given confidence level.
Reason:
The two main types of statistical methods are;
Inferential statistics methods; Theses are methods used to reach a
conclusion that extends past the given or available data.
Descriptive statistics methods; Theses are statistical method used as a
summary of a data set.
Given that the senator is trying to draw conclusion based on the data she
gathers, she should use inferential statistic method.
The type inferential statistic method that can be used is the confidence
interval.
From the data collected, the proportion of voters that view her favorably is
used at a given confidence level to determine the true proportion of voters
that view her favorably.
Therefore;
The statistical method that would be best for her to use is the
finding of the confidence interval which is a inferential statistic method.

Step-by-step explanation:
To find the x-intercept, substitute in 0 for y yand solve for x . To find the y-intercept, substitute in 0 for x and solve for y .
x-intercept(s): ( 6 , 0 )
y-intercept(s): ( 0 , − 2 )
Use the slope-intercept form y = m x + b to find the slope m and y-intercept b .
