A colored chip is yellow on one side and red on the other. The chip was flipped 50 times and landed up 29 times. What is the relative frequency of the chip landing with the yellow side facing up?

A.38%
B.42%
C.56%
D.58%

Answer:

C

Step-by-step explanation:

Label the two equations:

-2x -y= 9 -----(1)

2x -9y= 1 -----(2)

(1) +(2):

-2x -y +2x -9y= 9 +1

-2x +2x -y -9y= 10

Simplify:

-10y= 10

y= 10 ÷(-10)

y= -1

Substitute y= -1 into (2):

2x -9(-1)= 1

2x +9= 1

2x= 1 -9

2x= -8

x= -8 ÷2

x= -4

Thus, the solution is (-4, -1).

the slope goes by several names

• average rate of change

• rate of change

• deltaY over deltaX

• Δy over Δx

• rise over run

• gradient

• constant of proportionality

however, is the same cat wearing different costumes.

to get the slope of a straight line we only need two points off of it, hmmm let's use from the table (-1 , 13) and (2 , 1)

[tex](\stackrel{x_1}{-1}~,~\stackrel{y_1}{13})\qquad (\stackrel{x_2}{2}~,~\stackrel{y_2}{1}) \\\\\\ \stackrel{slope}{m}\implies \cfrac{\stackrel{rise} {\stackrel{y_2}{1}-\stackrel{y1}{13}}}{\underset{run} {\underset{x_2}{2}-\underset{x_1}{(-1)}}}\implies \cfrac{-12}{2+1}\implies \cfrac{-12}{3}\implies -4[/tex]

The required rate of change in the slope-intercept form is -4. Option A is correct.

The slope of the line is the tangent angle made by line with horizontal. i.e. m =tanx where x in degrees.

Here,
Two coordinates from the table,
(-2, 17) and (-1, 13)
Now,
Rate of change = slope of the function = (13 - 17) / (-1 - (-2))
                                                                 = -4 / 1
                                                                 = -4

Thus, the required rate of change in the slope-intercept form is -4. Option A is correct.

Answer:

[tex]y = 2\sqrt{10}[/tex]

Step-by-step explanation:

In left small right triangle: we have the square of left side = 5^2 + y^2 = 25 + y^2

In right small right triangle: we have the square of right side = 8^2 + y^2 = 64 + y^2

In the large right triangle, we have (25 + y^2) + (64 + y^2) = (5 + 8)^2

89 + 2y^2 = 13^2 = 169

2y^2 = 169 - 89 = 80

y = 80/2 = 40

so

[tex]y=\sqrt{40} = 2\sqrt{10}[/tex]

Step-by-step explanation:

cake sold today :- 85

cake sold yesterday :- X

relationship between caked sold :-

Today cake sold = cake sold yesterday- 16 (ATQ)

85 = x -16

85+16= x = 101 cakes

so Arvin sold 101 cakes yesterday

Answer:

Its 101

Hope this will help you

Step-by-step explanation:

Cake he sold today-85

Let the cake he sold yesterday be x,

x = 85+16

Therefore, x= 101

Therefore, He sold 101 cakes yesterday

The degree of the polynomial P(x) is the highest power of the polynomial P(X)

A possible formula for P(x) is [tex]P(x) =(x + 5)x^2(x - 1)^2 \\[/tex]

The given parameters are:

Roots of multiplicity 2 at x=1 and x=0

Root of multiplicity 1 at x= -5

Write out the roots

x=1 and x=0 ------- Multiplicity 2

x = -5  ------- Multiplicity 1

Equate the roots to 0

x - 1 = 0 and x = 0 ------- Multiplicity 2

x + 5= 0  ------- Multiplicity 1

Place the multiplicities as the exponents of the roots

(x - 1)^2 = 0 and x^2 = 0

(x + 5)^1 = 0

Multiply the expressions

[tex](x - 1)^2 * x^2 * (x + 5)^1 = 0 * 0 * 0[/tex]

This gives

[tex](x - 1)^2 * x^2 * (x + 5) = 0[/tex]

Rewrite as:

[tex](x + 5)x^2(x - 1)^2 = 0[/tex]

Replace 0 with P(x)

[tex]P(x) =(x + 5)x^2(x - 1)^2[/tex]

Hence, a possible formula for P(x) is [tex]P(x) =(x + 5)x^2(x - 1)^2 \\[/tex]

Answer: No solution

Step-by-step explanation:

-3x+3y=4

-x+y=3

We will rewrite the first equation and then substitute it into the second equation since we are solving by substitution.

Rewriting

-3x + 3y = 4

3y = 4 + 3x

y = [tex]\frac{4}{3}[/tex] + x

Substituting

-x + y = 3

-x + ([tex]\frac{4}{3}[/tex] + x) = 3

-x + [tex]\frac{4}{3}[/tex] + x = 3

[tex]\frac{4}{3}[/tex]  = 3

Answer:  0

Step-by-step explanation:

Rewrite as y = mx + b form, where m is slope and b is the y-intercept.

2y - 3 = -4 + 7

     2y = 3

       y = 3/2

There is only the y- intercept, 3/2, therefore the slope is 0.

Given -

↠ the length of a rectangle is 11 m less than three times the width (let the width be x then length = 3x - 11)

↠the area of the rectangle is 42 m².

To find -

the dimensions of the rectangle.

Solution -

As we know,

area of rectangle = length × width

➟ 42 = (3x - 11) x

➟ 42 = 3x² - 11x

➟ 3x² - 11x - 42 = 0

now splitting the middle term to find the value of x,

➟ 3x² - (18 - 7)x - 42 = 0

➟ 3x² - 18x +7x - 42 = 0

➟ 3x (x- 6) +7(x - 6) = 0

➟ (3x + 7)(x - 6) = 0

➟ x = -7/3, 6

➟ x = 6

We will take the value of x as 6 because the value of dimensions can never be in negative.

Hence, length = 3 × 6 - 11 = 7 cm and width = 6 cm

Answer:

h > 2

Step-by-step explanation:

It may look hard, but it is not really.

1. Solve

Here we have the equation 5+h>7.

All we have to do to find h is to subtract 5 from both sides.

5+h>7

-5     -5

When you subtract 5 from both sides, you get

5 - 5 = 0

7 - 5 = 2

All is left is 0+h>2, or h > 2.

2. Substitute

To make sure, (I do this but you can if you want to) I will substitute.

The values of h have to be greater than 2. So, Let's substitute 3.

5 + h > 7 --> 5 + 3 > 7

It's simple math.

5+3=8

8>7

Now, also to confirm, let's try a value less than 2, 1.

5 + h > 7

5 + 1 > 7

6 > 7 is not true, so it is confirmed that anything less than 2 is not true and anything greater is true.

Hence, h > 2

Hope this helps :)

Answer:

6 x a number - 9 = factored

In this case, since the number is not declared as a specific number, this is the key to us factoring.

Like the number could be 6. ↓

Factoring:

[tex]6*6-9=27\\6*3-9=9\\6*9-9=45[/tex]

bonus even factor:

[tex]6*2-9=3[/tex]

These are factors and Least common multiples of 6 and 9.

Because 9 and 3 show up during half of the problem, and these are related to 6 and 9, the parents, we could measure this on a mathematical scale that this proves the factors correct.

There are other ways to factor this. See comments.
