Hello.

Use the Distributive Property which states

a(b+c)=ab+ac

Simplify:

[tex]\hookrightarrow[/tex] [tex]\mathrm{3(9k-1)}[/tex]

[tex]\hookrightarrow[/tex] [tex]\mathrm{27k-3}[/tex]

Be sure to multiply 3 by both terms inside the parentheses.

I hope it helps.

Have an awesome day.

Hey there!

The Distributive Property states that

a(b+c)=ab+ac

where

a, b, and c can be either constants or variables.

Now that we know what the property states, let's simplify:

3(9k-1)

multiply:

3 times 9k and 3 times -1

27k-3

Hope everything is clear.

Let me know if you have any questions!

Answer:

No, Hillary is incorrect. There's 20oz of punch for every 4 servings.

Step-by-step explanation:

80oz / 20oz = 4

16 servings / 4 = 4 servings

So, instead of there being 20oz of punch for every 5 servings, there would be 20oz of punch for every 4 servings.

Answer: 17 degrees

Step-by-step explanation: Because you have angle A= 163, you can tell that angle B is 17 degrees (sum of angles on one side of a straight line add up to 180). Line M and line N are parallel, so they have corresponding angles, making angle B and angle X are the same. See picture attached for my diagram :). hope this helped!

Answer:

1/9

Step-by-step explanation:

4 people use all three facilities, then

16 - 4 = 12 people use the gym and the track and do not use the pool;

9 - 4 = 5 people use the pool and the track and do not use the gym;

19 - 4 = 15 people use the gym and the pool and do not use the track.

At least two facilities use 4 + 12 + 5 + 15 = 36 people, 4 of them use all three facilities. Thus, the probability that a randomly selected person which uses at least two facilities, uses all the facilities is 4/36 which is equivalent to 1/9

Using the z-distribution, as we have the standard deviation for the population, it is found that the smallest sample size required to obtain the desired margin of error is of 77.

The confidence interval is:

[tex]\overline{x} \pm z\frac{\sigma}{\sqrt{n}}[/tex]

In which:

The margin of error is given by:

[tex]M = z\frac{\sigma}{\sqrt{n}}[/tex]

In this problem, we have that the parameters are given as follows:

[tex]M = 3, z = 1.645, \sigma = 16[/tex].

Hence, solving for n, we find the sample size.

[tex]M = z\frac{\sigma}{\sqrt{n}}[/tex]

[tex]3 = 1.645\frac{16}{\sqrt{n}}[/tex]

[tex]3\sqrt{n} = 1.645 \times 16[/tex]

[tex]\sqrt{n} = \frac{1.645 \times 16}{3}[/tex]

[tex](\sqrt{n})^2 = \left(\frac{1.645 \times 16}{3}\right)^2[/tex]

[tex]n = 76.97[/tex]

Rounding up, the smallest sample size required to obtain the desired margin of error is of 77.

Answer:

Step-by-step explanation:

Multiply: (3x - 5)(-x + 4)

By applying the distributive property,

(3x - 5)(-x + 4)

= (3x)(-x) + (3x)(4) - (5)(-x) - (5)(4)

= -3x^2 + 12x + 5x - 20

= -3x^2 + 17x - 20

That is the simplified product in standard form.

Let's see

[tex]\\ \rm\longmapsto (3x-5)(-x+4)[/tex]

[tex]\\ \rm\longmapsto 3x(-x+4)-5(-x+4)[/tex]

Answer:

-1/3

Step-by-step explanation:(if treasure of change is "rate of change")

Equation of a line: mx + b

m=-1/3: slope

b: y-intercept

^Whenever working with an equation of slope/rate of change the above variables have specific meanings.

Slope is another term for rate of change so the rate of change would be -1/3.

m=-1/3=slope/rate of change

b=4=y intercept

The line plot is used to show the lengths of the string colors using  check marks above the line

From the complete question, we have the following frequency table

Blue string          4 in

White string         [tex]3\frac 12 \ in[/tex]

Brown string         [tex]3\frac 14 \ in[/tex]

Green string         [tex]4\frac 34 \ in[/tex]

Express as improper fraction

String color      Length

Black string        [tex]\frac {14}4 \ in[/tex]

Blue string          [tex]\frac{16}4\ in[/tex]

White string        [tex]\frac {14}4 \ in[/tex]

Brown string       [tex]\frac {13}4 \ in[/tex]

Green string        [tex]\frac {19}4 \ in[/tex]

Since the lengths are fractions and the string color is a text, then

We plot the lengths on the x-axis and the string color on the y-axis

Answer:

[1,∞)

Step-by-step explanation:

Let's try to plug in some numbers.

When solving a problem fo range, the best place to start is where you can let the (x - b) part = 0.

This is what I mean

3(x-6)² + 1

Let x = 6

3(0)² + 1 = 1

Look how we have a 0 inside the parentheses.

That's what I mean.

Now let's try using terms smaller than 6.

Now, let's try plugging in 5

3(-1)² + 1 = 4

Now try plugging in 4

3(-2)² + 1 = 13

Looks like we will just keep going up.

Now let's try using terms bigger than 6.

Plugging in 7

3(1)² + 1 = 4

Plugging in 8

3(2)² + 1 = 13

We just go up both ways because of the x squared term.

So our smallest value is at x = 6 where we have y = 1.

If we go either direction forever to the right or left the terms to get bigger, where it approaches infinity.

So, 1 will have parentheses as it can be reached and infinity will have parentheses as it is unreachable and goes on forever.

Answer:

$68.00

Step-by-step explanation:

16 x 425 = 6800

Just move the decimal 2 places to the left to get 68

Matthew spends $68 on gas as the rate of gas is $4.25 per gallon.

Per unit is a technique of expressing a quantity's value in terms of a base or reference quantity. Each system variable or quantity in a per-unit system is normalized in relation to its own base value.

Given Matthew bought 16 gallons of gas for $4.25 per gallon.

Since the price per gallon = 4.25

The price of the gas for 16 gallons = 4.25 * 16

The price of the gas for 16 gallons = 68.00

Therefore, Due to the $4.25 per gallon price, Matthew spends $68 on gas.

Answer:

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

Explanation:

The first task is to sort the items given.

The sorted set is {18, 20, 22, 26, 28, 30, 31}

There are 7 values in that set. The median is going to be in slot 4 because n/2 = 7/2 = 3.5 rounds to 4.

The value in slot 4 is 26, meaning the median is 26.

There are 3 values below the median, and 3 values above it.

L = lower set = items below the median

L = {18,20,22}

U = upper set = items above the median

U = {28,30,31}

The median of set L is 20, showing that Q1 = 20 is the first quartile.

The median of set U is 30, meaning Q3 = 30 is the third quartile.

The min and max are exactly what they sound like: they are the smallest and largest items. In this case, we have min = 18 and max = 31.
