Step-by-step explanation:

A discriminate of -8 is never going to give you a real root. D is wrong

You cannot have just 1 complex root, nor can you have just 1 real root unless the discriminate is 0. A and C are both wrong for the same reason. 1 complex root is impossible. They come in pairs.

So the answer is B. You have 2 complex roots.

Answer:

24:32

Step-by-step explanation:

When I saw that you wrote 'the ratios of BUTTERFLIES TO BEES' it tells me that I need to do the order of But. to Bees.  I saw you had 3:4, and you said, '32 bees' I know because of that, 32 bees needs to be the second.

I got my answer, by seeing 4x_=32.  I actually multiplied 4x8=32, and then multiplied 3x8 as well, to get 24.  Then I got my answer: 24:32!

Answer:

-10

Step-by-step explanation:

x + 75 + x + 125 = 180 add like terms

2x + 200 = 180 subtract 200 from both sides

2x = -20 divide both sides by 2

x = -10

Answer:

The point G represents: "60 dollars is the cost to dry clean 6 suits."

Step-by-step explanation:

If you look at the graph, on the bottom it shows number of suits, which is the independent. On the left it shows the cost of suits which is the dependent.

The dependent (Money) depends on the independent (Suits) so when you look at the point G you see that it is graphed on 6 suits for 60 dollars.

Answer:

(-2,-1)

Step-by-step explanation:

The solution is,  x = 3.06 and, y = -7.33..

An equation is a  mathematical statement that is made up of two expressions connected by an equal sign.  In its simplest form in algebra, the definition of an equation is a mathematical statement that shows that two mathematical expressions are equal. For instance, 3x + 5 = 14 is an equation, in which 3x + 5 and 14 are two expressions separated by an 'equal' sign.

here, we have,

5x + 4y = -14 ..(1)

y = -7x - 15

i.e. 7x + y = -15 ...(2)

for solving now, we multiply (2) by 4 , then subtract from (1),

we get,

5x + 4y = -14

20x + 4y = -60

------------------------

15x = 46

or, x = 3.06

and, y = -7.33

Hence, The solution is,  x = 3.06 and, y = -7.33.

Answer:Use the radioactive decay formula: A = Ao*2^(-t/h), where:

A = Amt of remaining after t time

Step-by-step explanation:

Ao = Initial amt

t = time of decay

h = half-life of the substance

in this problem

A = 21.5

Ao = 38

t = 1 year

h = half life of substance

Answer:

24

Step-by-step explanation:

1 ant = 6 legs

6 legs ×2 ants= 12 legs of ants

1 butterfly = 6 legs

2 butterfly ×6 legs = 12 legs of butterfly

total

12 legs of butterfly + 12 legs of ants

= 24 legs in total

Answer:

24

Step-by-step explanation:

1 ant = 6 legs

2 ants = 6 + 6 = 12

2 ants = 12 legs

1 butterfly = 6 legs

2 butterflies = 6 + 6 = 12

2 butterflies = 12 legs

12 + 12 = 24

There were 24 legs all together.

Answer:

Yes

Step-by-step explanation:

12/21 simplified is 4/7. if you divide the numerator (12) by 3 and the denominator (21) by 3, you get 4 and 7, or 4/7 if you put it together.

4/7 and 12/21 are equivalent fractions

A fraction represents a part of a whole.

We need to check whether the fractions  4/7 and 12/21  are equivalent or not.

Equivalent fractions are the fractions that have different numerators and denominators but are equal to the same value.

12/21 we have to simplify.

12 and 21 are the multiples of 3, so  divide numerator and denominator by 3

which gives 4/7

12/21=4/7

Hence, 4/7 and 12/21 are equivalent fractions

Given the following geometric sequence {0.45, 0.9, 1.8, ...}, the common ratio is 2. The common ratio = 1.8/0.9 = 0.9/0.45 = 2

Answer:

No

Step-by-step explanation:

Triangular Inequalities state that in a triangle, the sides must always be less than the sum of the other two.

You would have sides x, 2x, 3x in this case and use the inequality a+b>c.

if...

a=x, b=2x, c=3x

then...

x+2x>3x

3x>3x which is false.

Therefore you cannot make a triangle with sides proportional to 1, 2, and 3.

Step-by-step explanation:

p/q=2/3

q/r=6/5

First q is to be made same . So take LCM of 3 and 6 which is 6 only.

Now,

p/q=2×2/3×2=4/6

q/r=6/5 only

Cancel both the 6.

Therefore the answer is p/r=4/5.

Step-by-step explanation:

Answer:

Answer is -10

Step-by-step explanation:

Explanation:

First, define the variable. Let n represent the unknown number.

Next, write an equation to represent the situation. Because a quotient is the result of division, divide the unknown number by -5:

.

Then, use opposite operations and the properties of equality to solve for n. Notice that the variable, n, is divided by -5. So, to isolate n, do the opposite and multiply both sides of the equation by -5:

Finally, to check the solution, substitute -10 for n in the original equation:

The resulting statement is true, so the solution is correct.

Step-by-step explanation:

Answer:

The  upper bound of the 90% confidence interval is 0.181

Step-by-step explanation:

From the question we are told that

  The  sample size is  n  =  582

  The  number of accidents  is  k  =   91

Generally the sample proportion is mathematically represented as

         [tex]\r p = \frac{ k}{n} = \frac{582}{91 }[/tex]

=>     [tex]\r p = 0.1564[/tex]

Generally the confidence level is  90% , the level of significance is  [tex]\alpha  =  (100-90)\%[/tex]

=> [tex]\alpha =  0.10[/tex]

From the normal distribution table the critical value  of  [tex]\frac{\alpha }{2}[/tex] is  [tex]Z_{\frac{\alpha }{2} } =  1.645[/tex]

Generally the margin of error is mathematically represented as

       [tex]E  =  Z_{\frac{\alpha }{2} } * \sqrt{\frac{\r p (1 - \r p)}{n} }[/tex]

=>       [tex]E  =  1.645* \sqrt{\frac{ 0.1564 (1 - 0.1564)}{582} }[/tex]

=>        [tex]E =  0.0248[/tex]

Generally the 90% confidence interval is mathematically represented as

     [tex]0.1564 - 0.0248  <  p  <  0.1564  -0.0248[/tex]

=>   [tex]0.1316  <  p  <  0.1812[/tex]

Answer and Step-by-step explanation:

Random sample = 582

No. of accidents = 91

P = 91 / 582 = 0.156

Confidence interval for proportion of accidents:

P ± z √(p(1-p)/n)

Where,

n = 582

p = 0.156

z = 1.645

Formula:

P ± z √(p(1-p)/n)

put these values in formula, we get:

 = 0.156 ± 1.645 √(0.156(1-0.156)/582)

 = 0.156 ± 1.645 √(0.1316/582)

= 0.156 ± 1.645 (0.01483)

= 0.156 ± 0.0244

= (0.1804, 0.1316)
