pls help how do u solve for x

The probability of getting February, then a number less than 5 is:

P = 1/18

First, we need to find the two individual probabilities:

We have a total of 12 months, and we assume that the probability for each of these is the same one, then the probability of getting February will be:

p = 1/12.

Now, the standard die has 6 sides, the numbers that are less than 5 are:

{1, 2, 3, 4}

So 4 out of the 6 outcomes are less than 5, then the probability here is:

q = 4/6 = 2/3.

Then the joint probability is:

P = p*q = (1/12)*(2/3) = 2/36 = 1/18

⎡02413524−6⎦⎥⎥⎤ and B=⎣⎢⎢⎡−10021030−1⎦⎥⎥⎤

∴4A=⎣⎢⎢⎡081641220816−24⎦⎥⎥⎤ and 6B=⎣⎢⎢⎡−600126080−6⎦⎥⎥⎤ 

⇒4A−6B=⎣⎢⎢⎡0−(−6)8−016−04

Step-by-step explanation:

it all starts with having a good definition for a

a = 3x + 6

for the definition of b we need to transform the second equation

x = 1/3 b - 2 = b/3 - 2

3x = b - 6

3x + 6 = b

remember, if a = c and b = c, then it must be a = b.

that is the whole principle here. the symmetric property.

I am not sure what you must do here. so you select on the left the number of the step in the proof ?

if so, then

statement reason : number 1

a = 3x + 6 and 3x = b - 6 division : number 2

a = 3x + 6 and -b = -3x - 6 subtraction : number 3

a = 3x + 6 and b = 3x + 6 division : number 4

a = b = 3x + 6 symmetric : number 5

always remember, every change needed on one side of an equation we need to do on both sides, otherwise the equation is destroyed.

number 2 is "division" as division is a form of multiplication (and multiplication a form of division). we are multiplying by 3.

number 3 subtracts b and also 3x.

number 4 divides by -1.

and number 5 is the fished proof as mentioned above.

The value of x is -(11/7).

This problem is related to solving an algebraic equation.

In algebra there are many types of equations such as linear equation in one variable and two variable.

Here we have been given two variables and two equations which means we can solve the equation. To solve an equation in algebra it is important that the number of unknowns is equal to the number of equations given.

Given, m/1=2x+3 i.e., m=2x+3

also m/2=3x+7 i.e., m=6x+14

Now equating both the values of m;

The probability that at least one of them has been vaccinated is 0.9552

Probability:

Probability defines the possible occurrence of any particular required event.

Given,

Here we need to find in a large population, 54 % of the people have been vaccinated. if 4 people are randomly selected, what is the probability that at least one of them has been vaccinated.

Here we have to know that,

The situation where at least one out of 4 are vaccinated includes all but one possibility, that which none of the 4 are vaccinated.

The sum of all probabilities must equal 1.

Let Q be probability none of the 4 are vaccinated.

Let P be probability that at least 1 is vaccinated.

Then the probability is calculated as,

P = 1 - Q

Now if 54% are vaccinated, then 46% are not vaccinated.

Thus any given person has a probability of 0.46 of not being vaccinated.

=> Q = (0.46)⁴

=> Q = 0.0448

Then apply the value to the formula,

=> P = 1 - 0.0448

=> P = 0.9552

Therefore, the probability that at least one of them has been vaccinated 0.9552.

The correct option  is B.

In fact, a conversion factor is a number that is utilized to multiply as well as divide one set of units by another.. When converting to an equivalent value, the appropriate conversion factor must be utilized. To convert inches into feet, for example, the suitable conversion value becomes 12 inches equal to 1 foot.

Unit conversion is indeed a multi-step procedure that includes multiplying or dividing by a numerical factor, determining the appropriate number of important digits, and rounding.

The car gets 35 miles for each gallon of gas.

We need to calculate how many liters of petrol will be required for a 450-kilometer trip.

first converting km into miles:

1 km  =0.621371 miles.

So,

450 km = 450 x 0.621371

= 279.61 miles.

Now we know that :

One gallon of gasoline will get you 35 miles.

So for 279.61 miles.

Let x be the number of liters of gasoline required to travel the distance.

So

x = 279.61 / 35

x = 7.98 gallons

Now in litters:

1 gallon = 3.78541litters

So,

7.98 * 3.7854 = 30.24

                       = 3.0 x 10¹ litter

As a result, 3.0 x 10¹ litter of petrol will be used for a 450-kilometer trip.

There is a property of triangles which says that some of two sides of the triangle should be more than the third side of the triangle

So first case 6,30,5

30+6 =36 which is  more than 5

second case 5,30,6

5+30 =35 which is more than 6

third case 5,6,30

5+6 =11 which is not more than 30

as in third case the property is breached because sum of two sides of triangle is not more than third side so the figure cannot be a triangle .

Given,

Pizza pies with a choice of any of 4 toppings: pepperoni, mushrooms, green peppers, or sausage.

Here we need to find how many different pizzas can you make with anywhere from 0 to 4 toppings.

Here we need to assume that each pizza can have at most 1 serving of each topping.

Here we have four level of toppings like no serving, single serving, double serving and triple serving.

Suppose you had one topping, let's say mushrooms.  How many different possible pizzas would there be?

If you understand the setup right, there would be 4: no topping, single mushrooms, double mushrooms, or triple mushrooms.

Similarly, imagine that there are two toppings, mushrooms and sausage.

Then, there are 4 x 4 = 16 different combinations with two items.

We could continue this for a long time.  

If you have only sausage, mushroom, pepperoni and onion, then for a total of
