What are the possible rational roots of the polynomial equation?
0=2x9−3x7+11x+10
Answer:
+-1, +-2,+-5, +-10
Step-by-step explanation:
you first find all the numbers that can go into the constant which is 10, so negative and positive 1 can go into 10, negative and positive 2 can go into 10 etc.
The possible rational roots of the polynomial equation
[tex]1,-1} , +\frac{1}{2} , -\frac{1}{2} , +2,-2, +5,-5, +\frac{5}{2} ,-\frac{5}{2} ,+10,-10[/tex]
Given :
The polynomial equation is
[tex]2x^{9}-3x^{7}+11x+10=0[/tex]
To find out possible rational roots, we use rational root theorem
Rational root of the form
[tex]\frac{p}{q}[/tex] where p is the constant and q is the leading coefficient
p=10 and q=2
Lets write all the factors of 10 and 2
Factors of 10 are 1,2,5,10
factor of 2 are 1,2
Rational root of the form
[tex]+- factors of \frac{p}{q} =+-\frac{1,2,5,10}{1,2}[/tex]
We consider both positive and negative factors. Ignore the repeated roots
So possible rational roots are
[tex]1,-1} , +\frac{1}{2} , -\frac{1}{2} , +2,-2, +5,-5, +\frac{5}{2} ,-\frac{5}{2} ,+10,-10[/tex]

Some of the other shades of paint are more yellow than others. Which mixture(s) are the most yellow? chiesta haces of this paint are more yellow Explain your reasoning.
9514 1404 393
Answer:
2, 5, 6
Step-by-step explanation:
If we number the mixes 1-6 from top to bottom, then the fraction of the total that is yellow is ...
1. 1/(3+1+2) = 1/6
2. 2/(5+2+3) = 2/10 = 1/5
3. 2/(6+2+4) = 2/12 = 1/6
4. 4/(12+4+8) = 4/24 = 1/6
5. 6/(15+6+9) = 6/30 = 1/5
6. 8/(20+8+12) = 8/40 = 1/5
Mixes 2, 5, and 6 are the most yellow. (1/5 > 1/6)

Consider the function f(x) = -2x+15 . What is the value of y when x = 3?
Answer:
f(3) = 9
Step-by-step explanation:
Step 1: Define
f(x) = -2x + 15
x = 3
Step 2: Substitute and Evaluate
f(3) = -2(3) + 15
f(3) = -6 + 15
f(3) = 9
Write in slope intercept form:
(-5,-11) and (-2,1)
Answer:
y = 4x + 9
Step-by-step explanation:
First, find the slope of the line, which is the change in y/the change in x:
(-11-1)/(-5-(-2)) = -12/-3 = 4
That leaves you with the equation:
y = 4x
But notice, when x = -2 in the equation, y = -8, but we want it to be 1, so we add 9 to the end of the equation:
y = 4x + 9

evaluate the absolute value expression for x= -3 and y= -6
Answer:
-4
Step-by-step explanation:
So we are given the expression: | y - x | + y - 1, and we have our values for (x,y): (-3,-6).
So, we can just start plugging things in and simplifying, so:
| -6 + 3 | - 6 - 1 = | -3 | -7
= 3 - 7
= -4

Two part-time instructors are hired by the Department of Statistics and each is assigned at random to teach a single course in probability, inference, or statistical computing. Assume that more than one section of each course is offered. List the outcomes in the sample space [Hint: each element consists of a pair of assignments]. Find the probability that they will teach different courses. Note: carefully define your notation (e.g. any events) in words before solving the problem.
Answer:
The probability that they will teach different courses is [tex]\frac{2}{3}[/tex].
Step-by-step explanation:
Sample space is a set of all possible outcomes of an experiment.
In this case we will write the sample space in the form (x, y).
Here x represents the course taught by the first part-time instructor and y represents the course taught by the second part-time instructor.
Denote every course by their first letter.
The sample space is as follows:
S = {(P, P), (P, I), (P, S), (I, P), (I, I), (I, S), (S, P), (S, I) and (S, S)}
The outcomes where the the instructors will teach different courses are:
s = {(P, I), (P, S), (I, P),(I, S), (S, P) and (S, I)}
The probability of an events E is the ratio of the number of favorable outcomes to the total number of outcomes.
[tex]P(E)=\frac{n(E)}{N}[/tex]
Compute the probability that they will teach different courses as follows:
[tex]P(\text{Different courses})=\frac{n(s)}{n(S)}=\frac{6}{9}=\frac{2}{3}[/tex]
Thus, the probability that they will teach different courses is [tex]\frac{2}{3}[/tex].

Step-by-step explanation:
If: \qquad AC = 64 AB = 7x + 8, and BC= 3x+6, Find BC
The answer is 21.
First you Add both AB and BC which is 10x +14. Then you put 64 into the equation. 10x+14=64. Subtract 14 from 64 which is 50. So 10x=50. Then divide 10 from 50. which would be x=5. So if you plug it in. It would be 21.

Mr. Nell is painting his coffee table. The micture that he adds to the paint is made of 5/6 cup
baking soda for every 5 tablespoons of water.
What is the rate in cups of baking soda per tablespoon of water?
Answer:
1/6 cups
Step-by-step explanation:
5/6 /5 = 5/6 divided by 5
= 5/6 x 1/5
= 1/6
so your answer is 1/6 cups of baking soda per tablespoon of water
yw ;)
The rate for cups of baking soda per tablespoon of water is 1/6.
What is Division method?Division method is used to distributing a group of things into equal parts. Division is just opposite of multiplications. For example, dividing 20 by 2 means splitting 20 into 2 equal groups of 10.
Given that;
The mixture that he adds to the paint is made of 5/6 cup baking soda for every 5 tablespoons of water.
Hence, The rate for cups of baking soda per tablespoon of water is,
⇒ 5/6 ÷ 5
⇒ 5/6 × 1/5
⇒ 1/6

The "cold start ignition time" of an automobile engine is being investigated by a gasoline manufacturer. The following times (in seconds) were obtained for a test vehicle: 1.75, 1.92, 2.62, 2.35, 3.09, 3.15, 2.53, and 1.91. (a) Calculate the sample mean and sample standard deviation. (b) Construct a box plot of the data.
Answer:
(a) The sample mean and sample standard deviation are 2.415 and 0.5342 respectively.
(b) Shown below.
Step-by-step explanation:
The data set provided is:
S = {1.75, 1.92, 2.62, 2.35, 3.09, 3.15, 2.53, and 1.91}
(a)
Compute the sample mean and sample standard deviation as follows:
[tex]\bar x=\frac{1}{n}\sum\limits_{i}{x_{i}} =\frac{1}{8}\times 19.32=2.415\\\\\\s=\sqrt{\frac{1}{n-1}\sum\limits_{i}{(x_{i}-\bar x^{2})^{2}}}=\sqrt{\frac{1}{8-1}\times 1.9976}=0.5342[/tex]
Thus, the sample mean and sample standard deviation are 2.415 and 0.5342 respectively.
