Answer:

the answer is the fourth row

Answer:

hi! the answer is row four.

Step-by-step explanation:

it contains 14, 7, 2, -7, and -14

14 and -14 are opposite integers

&

7 and -7 are opposite integers

so, the row that has opposite integers would be row four.

Answer:

blank: 0.02

lettered: 0.98

vowel: 0.42

consonant: 0.56

Step-by-step explanation:

In the figure attached, the number of tiles of each letter are shown.

number of blank outcomes: 2

number of lettered outcomes: 98

number of vowel outcomes: 9 + 12 + 9 + 8 + 4 = 42

number of consonant outcomes: 98 - 42 = 56

Total number of outcomes: 100

Probability that first tile drawn is a blank tile: 2/100 = 0.02

Probability that first tile drawn is labeled with a letter: 98/100 = 0.98

Probability that first tile drawn is a  vowel: 42/100 = 0.42

Probability that first tile drawn is a consonant: 56/100 = 0.56

It's A, 1/5^9.

Ya take the two exponents, and subtract them. Now ya have 5^-9/5.

Since we can't have a negative exponent, we put it on the bottom.

So we get the answer 1/5^9. Hope this helps!

Answer:

1/5^9

Step-by-step explanation:

5^-6 goes down and become 5^6

then 5^3 is times 5^6, when multiplying two same bases their power has to be added not multiplied. so 6 plus 3 is 9. the nine is the power.

the final answer is 1/5^9 or the first choice

Weight of wood block is 15.543 ounces.

Given that;

Height of block = 4 inches

Diameter of block = 3 inches

1 cubic inch of wood = 0.55 ounces

Find:

Weight of wood block

Computation:

Radius of block = 3 / 2

Radius of block = 1.5 inches

Volume of toy = πr²h

Volume of toy = (3.14)(1.5)²(4)

Volume of toy = (3.14)(2.25)(4)

Volume of toy = 28.26 cubic inch

Weight of wood block = Volume of toy × 0.55 ounces

Weight of wood block = 28.26 × 0.55 ounces

Weight of wood block = 15.543 ounces

Hello there!

Mean is the average of a set of numbers.

To find the mean, we have to add all the numbers and divide by how many there are.

Add: 68 + 55 + 72  

Equals: 195

However, we have to find the mean of the 3 rounds in the 4th fight.

Add: 55 + 42 + 40

Equals: 137

Then, we divide it by 3.

Equals: 45.7

Next, add it to 195 since it was of 3 separate fights.

195 + 45.7 = 242.5

Lastly, divide it by 6 since there were 6 numbers in the data set.

Divide: 242.5/6

Equals: 40.42

Therefore, our mean for the 4 fights is 40.42 or 40.

There's another answer that we can get by simply adding up all the numbers and dividing it by 6.

Add: 68 + 55 + 72 + 55 + 42 + 40

Equals: 332

Then, we divide by 6.

Divide: 332/6

Equals: 55.33

So, yeah 55.33 would be the better mean then 40 since 40 makes it seem very low.

Answer:

Step-by-step explanation:

substitute a point value into the equation to find the missing number (the y-intercept)

you could either substitute (0,-4) or (1,2) into the equationn

y = 6x + b

-4 = 6(0) +b

-4 = 0+b

b = -4

or

y = 6x +b

2 = 6(1) + b

2= 6 +b

b= -4

Answer:

-4

Step-by-step explanation:

Y = mx+b is the slope intercept form of the equation

where m is the slope and b is the y intercept

The y intercept is where the line crosses the y axis

It is the value where x is zero

(0,-4)  the x value is zero so the y intercept is -4

Answer:

(-2y+5x) / (3x - 2y)

Step-by-step explanation:

If we write this sentence, we have:

((-2/x) + (5/y)) / ((3/y) - (2/x))

If we do LCM in the denominators of each fraction, we have:

((-2y+5x)/xy) / ((3x - 2y)/xy)

We can cut the 'xy' in the numerator and denominator of the whole fraction:

(-2y+5x) / (3x - 2y)

The final expression we have is (-2y+5x) / (3x - 2y)

Answer:

  y = 1/2x^2 +6

Step-by-step explanation:

The quadratic regression function of a calculator or spreadsheet is useful for this purpose. It shows you the equation is ...

  y = 1/2x^2 +6

_____

Alternate solution

Another way to approach this is to look at first and second differences of the y-values.

Sequence of y-values:

  6, 6.5, 8, 10.5, 14

Sequence of first differences:

  0.5, 1.5, 2.5, 3.5

Sequence of second differences:

  1, 1, 1, 1

The leading coefficient of the quadratic is half the value of the second differences: a = 1/2. The constant in the quadratic is the y-intercept, the value when x=0. The first point gives that as 6.

__

Now, you can check some other point to see what the linear term coefficient might be:

  y = 1/2x^2 +bx +6

For x=2, this is ...

  8 = 1/2(2^2) +b(2) +6 = 8 +2b . . . . . substitute (x, y) = (2, 8), simplify

  0 = 2b   ⇒   b = 0

Then the quadratic is ...

  y = 1/2x^2 +6

_____

Additional comment

You may not know the relation between second differences and the leading coefficient. The most general way to solve this is to write three equations in the unknown coefficients. Since y has integer values for x=0, 2, 4, you may want to use these. For (x, y) = (0, 6), (2, 8), and (4, 14), you have ...

  y = ax² +bx +c

After finding c=6 in the first equation, you have two equations in 2 unknowns:

The solution to these is a=1/2, b=0, as above.

Sample answer for Edmentum and Plato:

Answer:

y=4x

Step-by-step explanation:

In a proportional relationship, two values always have the same ratio to each other. This means that when we look at the equation of a line, y=mx+b, where m=slope and b=how much more plus the slope y is, there cannot be a "b" value.

An example of this is:

If the slope is 3,

y=3x

If x=2, y=6

If x=5, y=15

We can see that for every pair of coordinates, the ratio (5) between x and y remain the same.

y cannot have anything added to i (ex: y=3x+1), otherwise the ratio would change.

Ex:

If the equation is y=3x+1,

If x=1, y=4

If x=2, y=7

We can see that the ratios between the two numbers (1/4, 2/7) are not the same.

In this problem, the only equation without "b" is y=4x. Therefore, the answer is y=4x.

Answer:

The big number is 41 and the small number is 32.

Step-by-step explanation:

b + s = 73

2b - s = 50        Add these equations together

3b = 123            Divide both sides by 3

b = 41

Now plug this into the first equation to find s

41 + s = 73

-41       - 41

s = 32

Answer:

59

Step-by-step explanation:

Since b and the angle with measure 31 must add up to 90, you can set up the following equation.

b+31=90

b=90-31

b=59 degrees

Hope this helps!

Answer: 59 degrees

Step-by-step explanation:

Since it is a 90-degree angle all you do is subtract 90 from 31 and get 59.

Answer:

see explanation

Step-by-step explanation:

Differentiate [tex]\frac{4-x}{x}[/tex] using the quotient rule, given

y = [tex]\frac{f(x)}{g(x)}[/tex] , then

[tex]\frac{dy}{dx}[/tex] = [tex]\frac{g(x)f'(x)-f(x)g'(x)}{g(x)^2}[/tex]

Here f(x) = 4 - x ⇒ f'(x) = - 1

g(x) = x ⇒ g'(x) = 1 , thus

[tex]\frac{dy}{dx}[/tex] = [tex]\frac{-x-(4-x)}{x^2}[/tex] = [tex]\frac{-x-4+x}{x^2}[/tex] = - [tex]\frac{4}{x^2}[/tex]

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

Given

y = 3x² + [tex]\frac{4-x}{x}[/tex], then

[tex]\frac{dy}{dx}[/tex] = 6x - [tex]\frac{4}{x^2}[/tex] ← evaluate for x = 2

[tex]\frac{dy}{dx}[/tex] = 6(2) - [tex]\frac{4}{4}[/tex] = 12 - 1 = 11 ← as required
