Answers

Answer:

In particular, for an expression to be a polynomial term, it must contain no square roots of variables, no fractional or negative powers on the variables, and no variables in the denominators of any fractions.

So I'd say a polynomial is a finite sum of terms in which all variables have whole number exponents and no variable appears in a denominator. The leading term in a polynomial is the term of highest degree. The constant term in a polynomial is the term without a variable.

When would the median be the most effective way to describe a distribution?

The median is more likely to be accurate to the average value, even if it doesn’t calculate the average, because it is rarely affected by outliers. The mode, on the other hand, will be thrown off by outliers and won’t correctly represent most of the data.

if α and β are the zeros of p(x) = x² – 5x + 3, then find the value of α + β – αβ option (a)1, (b)2, (c)3, (d)5 please help​

Answers

Step-by-step explanation:

if you follow me I will give your answer

Answer:

» (b) 2

Step-by-step explanation:

Given equation :

p(x) = x²-5x+3

: α + β = sum of zeroes =

−(coefficient of x) / (coefficient of x²) =

-(-5) / 1 = 5/1 = 5

αβ = product of zeroes =

(constant term) /(coefficient of x²) = 3/1 = 3

So, → α + β – αβ ( α+β = 5 , αβ = 3 )

→ 5 – 3

→ 2

The price of a video game is marked up by 35%. What is the new price of the game before the markup was 40$? (help <3)

Answers

Answer:

Solution :

Selling price (S.P) = (100 + m)% ⋅ C.P

Here,

M = 35, C.P =40$

Then,

S.P = (100 + 35)% ⋅ 40

S.P = 135% ⋅ 40

S.P = 1.35 ⋅ 40

S.P = 54

So, the selling price is $54.

Answer:

$54

Step-by-step explanation:

Given:

Initial price = $40Mark up = 35%

Find the mark up price:

$40 + 35% = $40 + 0.35*$40 = $40 + $14 =$54

How do I find the value of X and Y

Answers

Answer:

x= -3.6

y= -2.8

Step-by-step explanation:

9x +17 =3x-5 ( interior angles are equal)

9x-3x +17= 3x-3x -5

6x+ 17+ 5= -5+5

6x/6= -22/6

x= -3.6

3x-5= 6y+1 ( vertical angles)

3(-3.6) -5 = 6y+ 1

-10.8 -5 -1= 6y +1 -1

-16.8 = 6y

-16.8/6 = 6y/6

y= -2.8

Two cards are randomly drawn. (5 blue cards and 3 yellow cards) What is the probability of drawing two blue cards if the fist card is not included in the second draw? simlify your answer completely

Answers

Answer:

5/14

Step-by-step explanation:

The probability of drawing a particular coloured card is the number of cards that are that colour, divided by the total number of cards:

The probability of drawing a blue card on your first draw would be 5 out of (5 + 3) = 5/8

The next draw would be the same principle, but the denominator (bottom number of the fraction) would be 1 less, because you have just taken out 1 card on your first draw:

The probability of drawing a blue card on your second draw (after drawing a blue card first) would be 4 (since you have already taken one) out of (8 - 1) = 4 / 7

To find the probability of both these steps combined, you multiply the two fractions together:

5/8 x 4/7 = 20/56

The question asks you to simplify, which means that the final answer is 5/14

Hope this helps!

help i need to know what k is

Answers

Answer:

k = 5

Step-by-step explanation:

The formula for coefficient of proportionality is y = kx.

In the given problem, the Area of a rectangle corresponds to "y" in the constant of proportionality formula, and "x" is still the same. Since the formula for the area of a rectangle is: A = L × W, then:

A = y

L = k

W = x

y = kx is the same as A = LW or A =  L × W

Thus, we're looking for the value for k, which corresponds to the length (L) (which has a constant value).

Below are the calculations for the missing values in the table:

We'll start with x = 0.14, and A = 0.7 since we're given the values for them. We could plug these values into the formula for the Area of a rectangle to find the constant value of the length (L):

A = L * W

0.7 = L * 0.14

Divide both sides by 0.14 to isolate L:

0.7/0.14 = (L * 0.14)/0.14

5 = L  ←← Keep in mind, this is the coefficient of proportionality.

x = 3.1:

A = L * W

A = 5 * 3.1

A = 15.5

x = 2.5:

A = 5 * 2.5

A = 12.5

x = 1.2:

A = 5 * 1.2

A = 6

x = 0.9:

A = 5 * 0.9

A = 4.5

Next, we're given the values for the Area, but we're missing the values for x. However, we already have the value for L = 5. We could still follow the same process by plugging in the values into the formula:

A = 0.3:

A = L * W

0.3 = 5 * W  

Divide both sides by 5 to solve for W:

[tex]\frac{0.3}{5} = \frac{5 * W}{5}[/tex]

0.06 = W

A = 0.1:

A = L * W

0.1 = 5 * W  

Divide both sides by 5 to solve for W:

[tex]\frac{0.1}{5} = \frac{5 * W}{5}[/tex]

0.02 = W

Therefore, k = 5.

Subtract -5x from both sides:

1/3 + -7/4 as a fraction in simplest form

Answers

Answer:

-17/12 = -1  5/12

Step-by-step explanation:

1/3-7/4=

*find a common denominator

*multiply the first fraction times 4 and the second one times 3

4/12- 21/12

-17/14

The addition of the fractions is determined as  [tex]\frac{1}{3}+\frac{-7}{4}=\frac{-17}{12}[/tex].

Given data:

To add the fractions 1/3 and -7/4, we need to find a common denominator. The least common multiple of 3 and 4 is 12. So, we will rewrite both fractions with a denominator of 12:

1/3 = (1/3) * (4/4) = 4/12

-7/4 = (-7/4) * (3/3) = -21/12

Now, we can add the fractions:

[tex]\frac{1}{3}+\frac{-7}{4}=\frac{4}{12}+\frac{-21}{12}[/tex]

[tex]= \frac{(4 - 21)}{12 }[/tex]

[tex]=\frac{ -17}{12}[/tex]

The result is [tex]\frac{ -17}{12}[/tex] . This fraction is already in its simplest form, meaning the numerator and denominator do not share any common factors other than 1.

In simpler terms, when we add 1/3 and -7/4, we first find a common denominator of 12. Then, we rewrite the fractions with that denominator and add them.

Hence, the fraction is [tex]\frac{ -17}{12}[/tex].
