Answer:

Independent events, 1/16

Step-by-step explanation:

What we must take into account is that they are 2 different bags, because in one bag are the black pieces and in another bag are the white feed, regardless of which piece is removed, one event has nothing to do with the other event being different bags.

Which means that they are independent events.

And the probability for each case would be 1/16, because the probability is one piece out of 16 that is in each bag.

Answer:

2y meters

Step-by-step explanation:

The first x meters are cancelled with the last x meters because after turning right two times they walk in the opposite direction that each of them started to walk.

The y meters each of them walk are also in the opposite direction, so given that each of them walked y meters, the distance between them is 2y meters.

Answer:

190

Step-by-step explanation:

550 + 25 = 575

575 - 100 = 475

475 - 202.5 = 272.5

272.5 - 82.5 = 190

The account balance at the end of the month would be; 190 dollar.

The addition is one of the mathematical operations. The addition of two numbers results in the total amount of the combined value.

We have given that Grant had an account balance of $550 in her checking account.

Then he deposits $25,

550 + 25 = 575

So he pays his annual credit card fee of $100.00,

575 - 100 = 475

Then he makes ATM withdrawals of $200.00

475 - 202.5 = 272.5

Then $80.00 from an ATM that charges a $2.50 fee per transaction.

272.5 - 82.5 = 190

Therefore, the account balance at the end of the month would be; 190 dollar.

Answer:

x = 14/3

Step-by-step explanation:

4(2x-3)+8(x-4)=2(2x+6)

Distribute

8x -12 +8x - 32 = 4x +12

Combine like terms

16x -44 = 4x+12

Subtract 4x

16x-4x -44 = 4x+12-4x

12x -44 =12

Add 44 to each side

12x-44+44 = 12+44

12x = 56

Divide each side by 12

12x/12 = 56/12

x = 14/3

Answer:

[tex]x=\dfrac{14}{3}[/tex]

Step-by-step explanation:

[tex]4(2x-3)+8(x-4)=2(2x+6)[/tex]

Expand parentheses:

[tex]8x-12+8x-32=4x+12[/tex]

Combine similar terms:

[tex]16x-44=4x+12[/tex]

Subtract 4x and add 44 to both sides:

[tex]12x=56[/tex]

Divide both sides by 12:

[tex]x=\dfrac{14}{3}[/tex]

Answer:

No, it is not in scientific notation. The first factor is not greater than or equal to 1.​

Step-by-step explanation:

Scientific notation is a method of writing numbers as the product of two factors where the first factor is a number whose absolute value is greater than or equal to 1 but less than 10.

Answer:

last option

Step-by-step explanation:

In scientific notation the number being multiplied by the power of 10 has to be in between 1 and 10, and since 0.11 doesn't satisfy this the answer is it is not in scientific notation because the first factor is not greater than or equal to 1.

Answer:

[tex][1250,1350)[/tex].

Step-by-step explanation:

It is given that a number, x, rounded to 2 significant figures is 1300.

It is possible if,

1. The value of x is greater than of equal to 1250 and less than or equal to 1300.

i.e., [tex]1250\leq x\leq 1300[/tex]     ...(1)

2. The value of x is greater than of equal to 1300 and less than 1350.

i.e., [tex]1300\leq x<1350[/tex]       ...(2)

On combining (1) and (2), we get

[tex]1250\leq x < 1350[/tex]

1350 is not included in the error interval for x.​

Interval notation is [tex][1250,1350)[/tex].

Therefore, the error interval for x is [tex][1250,1350)[/tex].

Answer:

19

Step-by-step explanation:

To write an equation for the first situation, you need to determine which factors can be changed.  The bus will not change since you can have multiple people in one.  The ticket to the museum is per person.  This will change depending on how many people there are.

450 + 15.75x

For the second equation, you need to find how many people can go for it the cost to be equal to $40 per person.  Set the equation equal to $40 per person and solve.

450 + 15.75x = 40x

450 = 24.25x

x = 18.56

Round up to 19 since you can't 0.56 of a person.

Answer: y =1

Step-by-step explanation:

Evaluating the equation for x  = 0:

y = 54 (0) + 1

y =1

The y-coordinate for the coordinate (0, y) is 1 if the coordinate (0,y) is a solution to the equation. Given the x-value of 0.

It is defined as the relation between two variables, if we plot the graph of the linear equation we will get a straight line.

If in the linear equation, one variable is present, then the equation is known as the linear equation in one variable.

The missing figure is attached to the picture.

Calculataing  the equation for x  = 0:

y = 54 (0) + 1

y = 1

Thus, the y-coordinate for the coordinate (0, y) is 1 if the coordinate (0,y) is a solution to the equation. Given the x-value of 0.

Answer:

The solution to the system of linear equation is (0,2)

The solution to the system of linear equation is (2.-3).

Simultaneous linear equations can be defined as the two- or three-variable linear equations that can be solved together to arrive at a common solution.

Here,

3x-y=9 - - - -(1)

4x+y=5 - - - - (2)

Adding equations 1 and 2

7x = 14

x = 2

Now, we have

3(2) - y = 9

-y = 9 - 6

-y = 3

y = -3

Thus, the solution of the given simultaneous equations are x = 2 and y = -3.

Answer: Then the sample space is 36.

Step-by-step explanation:

n is the number of possible combinations.

Now, as the die are of different colors, the case where:

white = 1 blue = 2, sum = 1+ 2 = 3

white = 2 blue = 1, sum = 2 + 1 = 3

are different.

So the number of possible combinations is:

6 options for the white dice and 6 options for the blue dice, so we have:

6*6 = 36 different combinations.

Then the sample space is 36.

Answer & Step-by-step explanation:

We can use the Pythagorean Theorem to find the value of x.

[tex]a^2+b^2=c^2[/tex]

For a, we will use 3.

For b, we will use 4.

For c, that will be our x.

[tex]3^2+4^2=c^2\\9+16=c^2\\25=c^2\\\sqrt{25} =\sqrt{c^2}\\ 5=c[/tex]

So, the value of x is 5.
