Answer:

  A)  Positive (4, 2, 0), negative (0)

Step-by-step explanation:

Descartes' rule of signs tells you the number of positive real roots is equal to the number of sign changes in the coefficients (with allowance for an even number of roots possibly being complex).

The signs of the coefficients are ...

  - + - + -

so there are 4 sign changes. The number of positive real roots will be 4, 2, or 0.

__

Changing the signs of odd-degree terms, you can use the same method to determine the number of negative real roots. With those signs changed, the signs of the coefficients are ...

  - - - - -

so there are 0 sign changes. The number of negative real roots is 0.

_____

The graph shows there are no real roots of either sign. All the roots are complex.

solve the equation:
-5|3x+8|-5=-2

Answers

Answer:

x = -2 13/15

Step-by-step explanation:

-5(3x+8)-5=-2

start by multiplying out the 5 to the numbers in the parenthesis.

= -15x-40-5=-2

subtract 5 from -40

=15x-45=-2

add the 45 to itself to get rid of it and add it to -2

=15x=43

divide 43 by 15

=2.8666666666 or -2 13/15

Select all the ratio that are equivalent to 8:6.

A. 4:3
B. 6:8
C. 16:12
D. 10:8
E. 7:5

Answers

4:3 and 16:12

4 times 2 is 8

3 times two is 6 therefore

4:3 has the same value

same with the second except it is 8 and 6 times 2

Answer: A and C

Step-by-step explanation: If you take the ratio and divide both sides by 2, you get the equivalent ratio 4:3. Then if you take the ratio and multiple both sides by 2, you will get the equivalent ratio 16:12. This means that both A and C are equivalent to the ratio 8:6.

Option 1)

6a + 8s = 102

14a + 4s = 150

each adult ticket costs 9 dollars

===================================================

Explanation:

6 adult tickets and 8 student tickets bring in $102, so that means 6a+8s = 102

14 adult tickets and 4 students tickets bring in $150, so 14a+4s = 150

The system of equations is

[tex]\begin{cases}6a+8s = 102\\14a+4s = 150\end{cases}[/tex]

If we multiply both sides of the second equation by -2, we get this updated system

[tex]\begin{cases}6a+8s = 102\\-28a-8s = -300\end{cases}[/tex]

Add the equations straight down

6a+(-28a) = -22a

8s+(-8s) = 0s = 0 ... the 's' terms go away

102+(-300) = -198

So we end up with the equation -22a = -198 and that solves to a = 9 after dividing both sides by -22.

Each adult ticket costs $9

If you want the value of s, then

6a+8s = 102

6(9)+8s = 102

54 + 8s = 102

8s = 102-54

8s = 48

s = 48/8

s = 6

Meaning each student ticket costs $6

Or you could use the other equation

14a+4s = 150

14(9)+4s = 150

126+4s = 150

4s = 150-126

4s = 24

s = 24/4

s = 6

We get the same value of s

Many states run lotteries to raise money. A website advertises that it knows​ "how to increase YOUR chances of Winning the​ Lottery." They offer several systems and criticize others as foolish. One system is called Lucky Numbers. People who play the Lucky Numbers system just pick a​ "lucky" number to​ play, but maybe some numbers are luckier than others.​ Let's use a simulation to see how well this system works. To make the situation​ manageable, simulate a simple lottery in which a single digit from 0 to 9 is selected as the winning number. Any value can be​ picked, but for this​ exercise, pick 1 as the lucky number. What proportion of the time do you​ win? Run 60 trials using the random numbers given​ below, starting with the first number. 89064 27308 64568 14121 98226 65388 58732 85801 69902 78431 10380 42006

Answers

Answer:

10 percent

Step-by-step explanation:

hello,

from this question, it has been stated that the lucky number is 1

from all of these values below we are to account how many times 1 appeared in these numbers have

89064, 27308, 64568 ,14121, 98226, 65388, 58732, 85801, 69902, 78431, 10380, 42006.

the total number of 1 is 6

= 6 x 1 divided by the number of trials 60

= 6 x 1/60

= 0.1

to get the proportion, we multiply 0.1 by 100

0.1 x 100

= 10%

A professional baseball player earned $1,715,000 from
playing baseball last year.
An autobiography he had written last year sold 300,000
copies at a price of $24 each. He received 10% in
royalties on the book sales.
What was his total salary last year?
$

Answers

Answer:

The right answer is actually $2,435,000.00

Step-by-step explanation:

The reason is because you take 300,000 and times that by 24 then you get 7,200,000 then you take that and times it by 0.10 then you get 720,000 then you add that to the 1,715,000 and you get 2,435,000.

300,000 x 24 = 7,200,000

7,200,000 x 0.10 = 720,000

720,000 + 1,715,000 = 2,435,000

So, $2,435,000.00 is your answer.

The total salary last year was $2,435,000 if a professional baseball player earned $1,715,000 from playing baseball last year.

What is the percentage?

It's the ratio of two integers stated as a fraction of a hundred parts. It is a metric for comparing two sets of data, and it is expressed as a percentage using the percent symbol.

It is given that:

A professional baseball player earned $1,715,000 from playing baseball last year.

The total earning from autobiography = 300,000x24

= 7,200,000

The royalty amount = 10% of 7,200,000

The royalty amount = 0.10x7,200,000

The royalty amount = 7,200,00

Total salary last year = 1,715,000 + 7,200,00

Total salary last year = $2,435,000

Thus, the total salary last year was $2,435,000 if a professional baseball player earned $1,715,000 from playing baseball last year.

The ratio can be defined as the proportion of the fraction of one quantity towards others. e.g.- water in milk.

Here,
Total of the ratios
CF = 3x + 2x + 1x
CF = 6x
6x = 42
x = 7
Now,

DF = DE + DF
DF = 2x + 1x
DF = 2 * 7 + 7
DF = 14 + 7
DF = 21

Thus, the required length of the DF on the line segment is 21 units.

Step-by-step explanation:

Simplify the following:

(7 + 1/4) 2^2 + (8 + 1/2 - 2)/3

2^2 = 4:

(7 + 1/4) 4 + (8 + 1/2 - 2)/3

Put 7 + 1/4 over the common denominator 4. 7 + 1/4 = (4×7)/4 + 1/4:

(4×7)/4 + 1/4 4 + (8 + 1/2 - 2)/3

4×7 = 28:

(28/4 + 1/4) 4 + (8 + 1/2 - 2)/3

28/4 + 1/4 = (28 + 1)/4:

(28 + 1)/4×4 + (8 + 1/2 - 2)/3

28 + 1 = 29:

29/4×4 + (8 + 1/2 - 2)/3

29/4×4 = (29×4)/4:

(29×4)/4 + (8 + 1/2 - 2)/3

(29×4)/4 = 4/4×29 = 29:

29 + (8 + 1/2 - 2)/3

Put 8 + 1/2 - 2 over the common denominator 2. 8 + 1/2 - 2 = (2×8)/2 + 1/2 + (2 (-2))/2:

29 + ((2×8)/2 + 1/2 + (2 (-2))/2)/3

2×8 = 16:

29 + (16/2 + 1/2 + (2 (-2))/2)/3

2 (-2) = -4:

29 + (16/2 + 1/2 + (-4)/2)/3

16/2 + 1/2 - 4/2 = (16 + 1 - 4)/2:

29 + ((16 + 1 - 4)/2)/3

16 + 1 = 17:

Using PEMDAS

Parentheses first

7 1/4 × 2²+(6 1/2)÷3

Then exponents

7 1/4 × 4+(6 1/2)÷3

Changing the mixed numbers to improper fractions

7 1/4 = (4*7+1)/4 = 29/4  and ( 2*6+1)/3 = 13/2

29/4 × 4+(13/2)÷3

Multiply and divide from left to right

29 + 13/2÷3

Using copy dot flip

29 + 13/2 * 1/3

29 + 13/6

Changing back to a mixed number

13/6 = 12/6 + 1/6 = 2 1/6

29 + 2 1/6

Add

The number which is closest to the addition of two fraction numbers, 1/2 + 1/3 is 0.8.

What is the fraction number?

A fraction number is the number which is a part of a whole number. It is written with a numerator and denominator. Fraction number are written as,

[tex]\dfrac{a}{b}[/tex]

Here, (a) is the numerator and (b) is the denominator.

We have to find the addition of two fraction number 1/2 and 1/3. Suppose the value which is closest to 1/2 + 1/3 is n. Thus,

[tex]n=\dfrac{1}{2}+\dfrac{1}{3}\\[/tex]

Cross multiply to find the addition of two numbers,

[tex]n=\dfrac{3+2}{6}\\n=\dfrac{5}{6}\\n=0.833[/tex]

Thus, the number which is closest to the addition of two fraction numbers, 1/2 + 1/3 is 0.8.

Is x=-4 a solution to the equation —3z + 10 = 5?

Answers

Answer:

No.

Step-by-step explanation:

First, note that there is no variable x inside the equation. Therefore, there is nothing for the -4 to plug into.

However, if you meant to put the same variable, it still will not work.

Plugging in -4 for z (if you meant z = -4), would give you the following:

Assuming that z = -4

-3(-4) + 10 = 5

-12 + 10 = 5

-2 ≠ 5.

Therefore, even if you did mean to put the same variable, it will still not be correct.

~

For the given equation, there is no variable x but z is a variable in the linear equation. Since x is not a variable of the equation, we can't put the value given.

But if we plug the value of -4 in place of z:

➝ -3(-4) + 10

➝ 12 + 10

➝ 22 which is not equals to 5.

Hence, this equation is not satisfying for the value of variable given that is 4. Thus, -4 is not a solution to the given equation[tex].[/tex]
