Answer:

Sample Response: As the number of trials changes, the distribution changes. Since there is a 50% chance of rolling an even number, having a small number of successes is less likely when the number of rolls increases.

Step-by-step explanation:

Also, heart and rate if you found this answer helpful!! :) (P.S It makes me feel good to know I helped someone today!!)  :)  

Answer:

I believe the answer is D

Step-by-step explanation:

Given:

The given expression is

[tex]-4(x+2)-2x+4[/tex]

To find:

The two other equivalent expressions.

Solution:

We have,

[tex]-4(x+2)-2x+4[/tex]

Using distributive property, we get

[tex]=-4(x)-4(2)-2x+4[/tex]

[tex]=-4x-8-2x+4[/tex]

So, one equivalent expression is [tex]-4x-8-2x+4[/tex].

On further simplification, we get

[tex]=(-4x-2x)+(-8+4)[/tex]

[tex]=6x-4[/tex]

Therefore, the second and fully simplified equivalent expression is [tex]6x-4[/tex].

Answer:

1/4

Step-by-step explanation:

If there are two pies and eight friends, then 4 friends split each pie. I know this because if you divide eight by two (because there are 8 friends and 2 pies) then you get 4, which means then 4 friends split each pie. You would then figure out how many slices you need to split each pie into. Since there are 4 people per pie, you would split each pie into 4 sections. Each friend would get 1/4 of a pie.

I hope this makes sense to you. If you need any more help, please let me know. I'm always happy to help! :]

Answer:

B. $63.19

Step-by-step explanation:

You will pay $63.19 for a item with original price of $78.99 when discounted 20%. In this example, if you buy an item at $78.99 with 20% discount, you will pay 78.99 - 15.798 = 63.19 dollars.

Step-by-step explanation:

Answer:

B; one solution

Step-by-step explanation:

Here, we want to get the number of solutions the system of linear equations has

From what we have in the diagram, we can see that the two lines cross at a point

The point at which these two lines meet is the solution to the system

What we are saying is that the (x,y) of the point at which the two equations meet represent the solution

Answer:

16 eggs

Step-by-step explanation:

Steps to answering this question

Number of eggs needed for one cookie = 4/30 = 0.1333

Number of eggs needed for 120 cookies = 0.1333 x 120 = 16 eggs

Answer:

- ( 5x + y ) ( x + 5y )

or

-5x^2 - 5y^2 - 26xy

Answer:

Step-by-step explanation:

4(x^2-2xy+y^2)-9(x^2+2xy+y^2)

4x^2-8xy+4y^2-9x^2-18xy-9y^2

-5x^2-26xy-5y^2

-5x^2-xy-25xy-5y^2

-x(5x+y)-5y(5x+y)

(-x-5y)(5x+y) or you can also remove the negative one to get

-(x+5y)(5x+y)

Answer:

[tex]\bold{5x-5}[/tex]

Step-by-step explanation:

Hi there!

The Distributive property states that

[tex]\bold{a(b+c)=ab+ac}[/tex]

So, we take a number a, multiply it by b and c, and then add the products.

Now, let's solve the given math problem:

[tex]\bold{5(x-1)}[/tex]

[tex]\bold{5x-5}[/tex]

Hope it helps! Enjoy your day!

Answer:

Length = 16 in

Width = 12 in

Step-by-step explanation:

Given:

Area of a rectangle = 192 in²

Ratio(length to width) = 4:3

Find:

Length and the width

Computation:

Ratio(length to width) = 4:3

So,

Length = 4a

Width = 3a

Area of a rectangle = Length x Width

192 = 4a x 3a

192 = 12a²

a² = 16

a = 4

Length = 4a = 4 x 4 = 16 in

Width = 3a = 3 x 4 = 12 in

Step-by-step explanation:

Answer:

Correct

Step-by-step explanation:

To isolate the variable of x, simply add 16 to 11 which is 27 and now it is set up as 4.5x=27 and 27/4.5, it = 6

Answer:

Gray and all are right.

Step-by-step explanation:

4.5x + 16 = 11.5

4.5x = 11.5 - 16

4.5x = -4,5

x = -4.5/4.5

x = -1

4.5x + 27 = -9

4.5x = -9 - 27

4.5x = -36

x = -36/4.5

x = -8

4.5x - 16 = 11

4.5x = 11 + 16

4.5x = 27

x = 27/4.5

x = 6

-4.5x + 27 = 45

-4.5x = 45 - 27

-4.5x = 18

x = 18/-4.5

x = -4

Answer:

The answer is

[tex]18\sqrt{3} [/tex]

If you need any explanation in it or anything on math you can communicate with me on Whats on this number +201557831028 or in email or face or anything

Step-by-step explanation:

This triangle is equilateral

Then

[tex]db = \frac{1}{2} ab = .5 \times 12 = 6 [/tex]

By using the phythgorth thearm you can find CD

[tex]cd = \sqrt{ {ab}^{2} - {db}^{2} } \\ = \sqrt{144 - 36} = 6 \sqrt{3} [/tex]

Then the eara of triangle is

[tex] \frac{1}{2} \times 6 \times 6 \sqrt{3} = 18 \sqrt{3} [/tex]

Answer:

Use photo math, it will explain it all in different forms

Answer:

1. The square root of 100

2.c=27.11

d=13.96

e=12.6

Step by step explanation:

1. 2×50=100 the geometric mean is the square root of 100

2. The diagram is made up of three right angled triangles the big outer one and two triangles inside the big one thus we can use the pythagorean theorem to come up with expressions which will help us in solving the unknown parts as below.

c²=30²-d²

c²=e²+24²

d²=e²+6²

both the following add up to c² meaning they are equal:

c²=30²-d²

c²=e²+24²

thus

30²-d²=e²+24²

I want to remain with d² only thus;

30²-24²-e²=d²

900-576=324 (squareroot of 324=18) so

d²=18²-e² and d²=e²+6²

both the above add up to d² meaning they are equal thus;

18²-e²=e²+6²

18²-6²=e²+e²

324-36=2e²

318=2e²

159=e²

e=12.61

Thus d²=e²+6²

d²=12.61²+6²

d²=159+36

d²=195

d=13.96

c²=e²+24²

c²=12.61²+24²

c²=159+576

c²=735

c=27.11

I hope this helps

Answer:

[tex]5^{12}[/tex]

Step-by-step explanation:

Lets say there's a number 'x' and there's an expression [tex](x^a)^b[/tex] where 'a' & 'b' are also numbers , the simplified form of the expression is [tex]x^{a \times b}[/tex].

So ,

[tex](5^4)^3 = 5^{4 \times 3} = 5^{12}[/tex]

First Question:

Follow PEMDAS

Parentheses, Exponents, Multiplication or Division, Addition or Subtraction

3 ÷ [tex]\frac{1}{4}[/tex] × (12 + 2³)

= 3 ÷ [tex]\frac{1}{4}[/tex] × (12 + 8)

= 3 ÷ [tex]\frac{1}{4}[/tex] × (20)

= 3 × 4 × 20

= 12 × 20

= 240

Second Question:

change the mixed number into an improper fraction:

[tex]3\frac{2}{3}[/tex] = [tex]\frac{11}{3}[/tex]

= [tex]\frac{11}{3}[/tex] ÷ [tex]\frac{3}{4}[/tex]

= [tex]\frac{11}{3}[/tex] × [tex]\frac{4}{3}[/tex]

= [tex]\frac{44}{3}[/tex]

rounded to WHOLE number: 14 containers
