Answer:

Terms: 8, (-x²), x, (-4x)

Like terms: x and (-4x)

Step-by-step explanation:

A term is a single number (positive or negative), a single variable (a letter), or several variables multiplied but not added or subtracted.

Like terms are terms that have the same variables and power like x.

Answer:

The 3 digit numbers are;

171, 152, 133, 114, 285, 266, 247, 228, 209, 399

Step-by-step explanation:

Let the 3 digit number be xyz

Since x is the Hundreds digit, y is the tens digit and z is the unit digit, we have;

100x, 10y and z

We are told the sum of this is equal to 19 times the sum of their digits.

Thus;

100x + 10y + z = 19(x + y + z)

100x + 10y + z = 19x + 19y + 19z

This gives;

81x - 9y - 18z = 0

Divide through by 9 to get;

9x - y - 2z = 0

x = (2z + y)/9

Now, we will need to select values of z and y between 0 to 9 in such a way that (2z + y) is divisible by 9 and in such a way that x > 0 but ≤ 10

The possible solutions are;

At z = 1, y = 7 and x = 1

At z = 2, y = 5 and x = 1

At z = 3, y = 3 and x = 1

At z = 4, y = 1 and x = 1

At z = 5, y = 8 and x = 2

At z = 6, y = 6 and x = 2

At z = 7, y = 4 and x = 2

At z = 8, y = 2 and x = 2

At z = 9, y = 0 and x = 2

At z = 9, y = 9 and x = 3

Compiling all these, the 3 digit numbers are;

171, 152, 133, 114, 285, 266, 247, 228, 209, 399

Answer:

a) point estimate for the population proportion of all customers who experienced an interruption

E = 0.029

b)

90% confidence interval for the proportion of all customers who experienced an interruption

(0.11441 , 0.16319)

C)

Size of the sample 'n' = 509

Step-by-step explanation:

Step(i):-

a)

An Internet service provider sampled 540 customers and found that 75 of them experienced an interruption in high-speed service during the previous month.

Sample proportion

                           [tex]p = \frac{x}{n} = \frac{75}{540} = 0.1388[/tex]

The point estimate of all customers who experienced an interruption

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

  Level of significance

                          Z₀.₀₅ = 1.96

                         [tex]E = \frac{1.96\sqrt{0.138(1-0.1388)} }{\sqrt{540} }[/tex]

                         E  =  0.029

b)

90% confidence interval for the proportion of all customers who experienced an interruption

[tex]( p - Z_{0.10} \sqrt{\frac{p(1-p)}{n} } ,p + Z_{0.10} \sqrt{\frac{p(1-p)}{n} })[/tex]

[tex]( 0.1388 -1.645 \sqrt{\frac{0.1388(1-0.1388)}{540} } ,0.1388 + 1.645 \sqrt{\frac{0.1388(1-0.1388)}{540} })[/tex]

( 0.1388 - 0.02439 , 0.1388 + 0.02439)

(0.11441 , 0.16319)

c)

Margin of error

                   [tex]M.E = \frac{Z_{0.05} \sqrt{p(1-p)} }{\sqrt{n} }[/tex]

                   [tex]0.03 = \frac{1.96 \sqrt{0.1388(1-0.1388)} }{\sqrt{n} }[/tex]

                   √n = 22.58

Squaring on both sides, we get

                 n = 509

Answer:

Width = [tex]7\frac{11}{16}[/tex] inches

Step-by-step explanation:

Given

[tex]End_1 = 2\frac{3}{4}[/tex]

[tex]End_2 = 10\frac{7}{16}[/tex]

Required

Determine the width of frame in between

To do this, we simply calculate the difference between both ends:

i.e.

[tex]Difference = End_2 - End_1[/tex]

This gives:

[tex]Difference = 10\frac{7}{16} - 2\frac{3}{4}[/tex]

Convert to improper number

[tex]Difference = \frac{167}{16} - \frac{11}{4}[/tex]

Take LCM

[tex]Difference = \frac{167 - 44}{16}[/tex]

[tex]Difference = \frac{123}{16}[/tex]

[tex]Difference = 7\frac{11}{16}[/tex]

Hence, the width of the frame is [tex]7\frac{11}{16}[/tex] inches

❤❤❤❤❤❤❤❤❤❤❤❤❤❤❤

[tex] \frac{x - 1}{2} - \frac{x - 2}{3} > \frac{x - 3}{4} \\ [/tex]

Multiply sides by 12

[tex]12 \times ( \frac{x - 1}{2} - \frac{x - 2}{3} ) > 12 \times ( \frac{x - 3}{4} ) \\ [/tex]

[tex](12 \times \frac{x - 1}{2} ) - (12 \times \frac{x - 2}{3} ) > 12 \times \frac{x - 3}{4} \\ [/tex]

[tex](6 \times \: (x - 1)) - (4 \times (x - 2)) > 3 \times (x - 3) \\ [/tex]

[tex]6x - 6 - (4x - 8) > 3x - 9[/tex]

[tex]6x - 6 - 4x + 8 > 3x - 9[/tex]

[tex]6x - 4x + 8 - 6 > 3x - 9[/tex]

Collect like terms

[tex](6 - 4)x + 2 > 3x - 9[/tex]

[tex]2x + 2 > 3x - 9[/tex]

[tex]3x - 9 < 2x + 2[/tex]

Add sides 9

[tex]3x - 9 + 9 > 2x + 2 + 9[/tex]

[tex]3x > 2x + 11[/tex]

Subtract sides 2x

[tex] - 2x + 3x > - 2x + 2x + 11[/tex]

[tex]x > 11[/tex]

Answer:

The second to last choice

Step-by-step explanation:

Answer:

I would say 14 weeks.

Step-by-step explanation:

I solved it by subtracting what she already has from the price of the bike. $164-52= 112. Then I divided that by 8 cause she saving $8 a week and you get 14. So in 14 weeks she'll have enough money to buy the bike.

Answer:

Area = 3x² + 7x + 3

Perimeter = 8x + 8

Step-by-step explanation:

The figure can be decomposed into two: a large rectangle and a smaller rectangle.

✍️Dimensions of the large rectangle:

Length = (x + 1) + x = x + 1 + x = (2x + 1)

Width = (x + 3)

Area = length × width

Area = (2x + 1)(x + 3)

Expand

2x(x + 3) +1(x + 3)

2x² + 6x + x + 3

Area = 2x² + 7x + 3

✍️Dimensions of the large rectangle:

Length = x

Width = x

Area = length × width

Area = x × x = x²

✍️Area of the figure = area of the large rectangle + area of the smaller rectangle

Area of the figure = (2x² + 7x + 3) + x²

Area of the figure = 2x² + x² + 7x + 3

✅Area = 3x² + 7x + 3

✍️ Perimeter of the figure = sum of the length of all sides of the figure = (x + 3) + x + x + x + (x + 1) + (x + 3) + (x + 1) + x

✅Perimeter = 8x + 8

Answer:

[tex]ln(4)+2\,\,ln(y)[/tex]

(the first option of the list)

Step-by-step explanation:

Using the properties of logarithms (first the logarithm of a product and then the logarithm of a power, we write:

[tex]ln(4\,y^2)=ln(4)+ln(y^2)=ln(4)+2\,\,ln(y)[/tex]

which agrees with the first option in the list of possible answers.

Answer:

8 out of 11

Step-by-step explanation:

Answer:

Step-by-step explanation:

1. 150 to 132 is a decrease of 12%

2. 275 to 242 is a decrease of 12%

3. 300 to 255 is a decrease of 15%

Thanks For the Brainliest!

Answer:

1. 150 - 12% = 132

2. 275 - 12% = 242

3. 300 - 15% = 255

Answer:

[tex]\huge\boxed{82 \textdegree}[/tex]

Step-by-step explanation:

We know that all angles in a triangle will add up to 180°. Since we know the measure of all 3 angles, we can create this equation:

[tex]31+x+(x-15) = 180[/tex]

Let's solve for x.

Combine like terms:

[tex]31+2x-15=180[/tex]

Add 15 to both sides:

[tex]31+2x=195[/tex]

Subtract 31 from both sides:

[tex]2x=164[/tex]

Divide both sides by 2:

[tex]x= 82[/tex]

So x is 82°.

Answer:

33.333....   or   33 33/100

Step-by-step explanation:

10 potatoes makes 15 pounds of mashed potatoes can be written like 10/15

and that means x potatoes make 50 pounds of mashed potatoes

so it looks like 10/15=x/15

so 10times20divided by15=x

x=
