please help me simplify this -1/9 (9-27a)=?

On the roll a special "24-sided" die, the probability that the number is a "1" or a "2" is 1/12.

The probability of rolling a "1" or "2" on a 24-sided die is the sum of the probabilities of rolling a 1 and rolling a 2, because the events are mutually exclusive.

Since each face of the 24 sided-die is equally likely to come up, the probability of rolling any particular-face is 1/24.

So, the probability of rolling a "1" is 1/24, and the probability of rolling a "2" is also 1/24.

The probability of rolling either a 1 or a 2 is the sum of these probabilities:

⇒ P(rolling a 1 or a 2) = P(rolling a 1) + P(rolling a 2),

⇒ 1/24 + 1/24,

⇒ 2/24,

⇒ 1/12.

Therefore, the required probability is 1/12.

Answer:

15 customers were outside

Step-by-step explanation:

Represent customers inside with x and customers outside with y.

So, we have:

[tex]x = \frac{1}{3}y - 2[/tex] --- First Statement

[tex]x = 3[/tex] --- Second Statement

Required

Find y

Substitute 3 for x in [tex]x = \frac{1}{3}y - 2[/tex]

[tex]3 = \frac{1}{3}y - 2[/tex]

Add 2 to both sides

[tex]2 + 3 = \frac{1}{3}y - 2 + 2[/tex]

[tex]2 + 3 = \frac{1}{3}y[/tex]

[tex]5= \frac{1}{3}y[/tex]

Multiply both sides by 3

[tex]3 * 5= \frac{1}{3}y *3[/tex]

[tex]15 = y[/tex]

[tex]y = 15[/tex]

Hence; 15 customers were outside

The solution is, Multiplication is a cows favorite type of math.

Gelett Burgess, author of The Purple Cow (1866–1951), I've never seen a Purple Cow and I've never hoped to; nevertheless, I can tell you that I'd much prefer see than be one. Death is a definite fact and a guarantee of life. Despite his unflinching devotion, Andrew Hudgins admits that the cow will inevitably die when it becomes feeble since he will slaughter it in stanza three. When she becomes too weak to provide us with fresh cream, we will cut her scarlet throat. Gelett Burgess, an American author, wrote a brief nonsensical poem titled "Purple Cow." In 1895, it was first printed.

here, we have,

In an experimental setup the independent variable is the one which can be changed and manipulated in an experiment the effect of which is observed on the dependent variable (s). The dependent variable is the one which cannot be manipulated in an experiment instead the changes occurring in a dependent variable are because of the manipulation of the independent variable. The dependent variable represents the outcome of the experiment.

According to the given situation, type of feed is the independent variable this is because of the fact that the there were two type of feeds were used one was experimented feed other was regular feed. The effect of both type of feeds has been observed on the weight of the cow which is the dependent variable.

This implies that the rate is 21.67 hours/ week

Answer:

16 subsets

Step-by-step explanation:

To know the number of subsets that the set have, we will have to find the power of the set.

Given the set a = ( a,b,c,d)

P(a) = 2^n where;

n is the total number of element in the set

n = 4

p(a) = 2^4

P(a) = 16

Hence the set has 16 subsets

Step-by-step explanation:

4(6) - 7y = -18

24 - 7y = -18

-7y= -42

y= 6

Answer: y=6

Step-by-step explanation:

4(6)-7y=-18

24-7y=-18 subtract 24 on both sides

-7y=-42 **then divide -7 on both sides**

Answer:

Step-by-step explanation:

The way to do this (I think) is to figure out the probability of not getting said king on either throw.

First Throw: P(no King Hearts) = 51/52

Second Throw: P(no King Hearts) = 50/51

Total probability = 51/52*50/51 = 50/52

Therefore the probability of getting it right is

P(KH) = 1 - 50/52 = 2/52 = 1/26

I have a feeling that this is not correct. If you get a different answer  that looks reasonable, take it.

Answer:

Mark's mass is 26 kg.

Step-by-step explanation:

Average mass of Jeremy, Mark and Zack = 28kg

Average mass of Jeremy and Zack = 29 kg

Let,

Jeremy's mass = x

Mark's mass = y

Zack's mass = z

Average of three of them = [tex]\frac{Jeremy's mass + Mark's + Zack's}{3}[/tex]

28 = [tex]\frac{x+y+z}{3}\\[/tex]

[tex]28*3 = x+y+z\\84 = x+y+z[/tex]

x+y+z = 84     Eqn 1

[tex]29 =\frac{x+z}{2}\\58=x+z\\[/tex]

x+z = 58    Eqn 2

Now putting value of x+z from Eqn 2 in Eqn 1

x + z + y = 84

58 + y = 84

y = 84 - 58

y = 26

Thereofore,

Mark's mass is 26 kg.

-2a - 2b

Step-by-step explanation:

Question : (4a + b)-3(2a + b)

= 4a + b - 6a - 3b

= 4a - 6a + b - 3b

= -2a + (-2b)

= -2a -2b

If you need detail solution here ;

first + multiply both 4a and b

first -3 multiply both 2a and b and then -3×2a= -6a

-3×b = -3b

and it will be 4a + b -6a -3b,then collect like terms

4a - 6a + b -3b

= -2a +(-2b) in this part + tims - = -

= -2a - 2b

2 units

Step-by-step explanation:

Given data

The points are  (2, 3) and (2, 5)

x1= 2

y1= 3

x2= 2

y2= 5

substitute into the distance between two points formula

d=√((x_2-x_1)²+(y_2-y_1)²)

d=√((2-2)²+(5-3)²)

d=√(2)²)

d=√4

d= 2 units

Hence the length is 2 units
