what is the number of possible outcomes if two quarters are tossed at the same time and the numbers of heads and tails are counted

Answer:

a = 8 2/3.

Step-by-step explanation:

The y coordinate of the point is 5, andthe x coordinate is a so substituting for these in the given equation:

3a - 4(5) = 6

3a  - 20 = 6

3a = 26

a = 26/3

= 8 2/3

[tex]\huge\underline{\red{A}\blue{n}\pink{s}\purple{w}\orange{e}\green{r} -}[/tex]

here , we've been given a point with coordinates ( a , 5 ) and an equation ( 3x - 4y = 6 ).

Coordinate geometry deals with parameters related to points over cartesian plane , where a points , say G , has two coordinates x and y.

the coordinates are written as ( x , y ) , where x is the x coordinate or abcissa and y is the y coordinate or ordinate.

for getting the solution to the question asked , let us think of x as a and y as 5.

Now ,

substituting the values of x and y in the equation ,

[tex]3x - 4y = 6 \\ \implies \: 3(a) - 4(5) = 6 \\ \implies \: 3a - 2 = 6 \\ \implies \: 3a = 6 + 20 \\ \implies \: 3a = 26 \\ \implies \: a = \frac{26}{3} [/tex]

let's once check , if we've arrived at the correct result or no.

This can be done , by putting value of x as [tex]\frac{26}{3}\\[/tex] which is the value of a.

So ,

[tex]3x - 4y = 6 \\ \\ \implies \: \cancel3 (\frac{26}{\cancel3} ) - 4(5) = 6\\ \\ \implies26 - 20 = 6 \\ \\ \implies \: 6 = 6[/tex]

hence , verified !

Therefore ,

[tex]\bold\red{a = \frac{26}{3} }\\ [/tex]

Answer:

205 minutes

Step-by-step explanation:

If Monica has already practiced 18% of her time, we know that she has practiced [tex]\frac{18}{100}[/tex]. If this 18% corresponds to 45 min, we can have the following equation: [tex]\frac{18}{100} = \frac{45}{x}[/tex]. We can rearrange the equation to find the value of x by doing [tex]x = \frac{45 \cdot 100}{18} = 250[/tex], so she practices 250 min every Wednesday. If we subtract the time she has already practiced (45 min) we find out she still has to practice more 205 min.

Answer:

3/13

Step-by-step explanation:

There are a total of 13 letters in the word and 3 of them are A’s so 3/13 is the probability of getting an A.

The probability of getting the letter A is given by P ( A ) = 3/13

The probability that an event will occur is measured by the ratio of favorable examples to the total number of situations possible

Probability = number of desirable outcomes / total number of possible outcomes

The value of probability lies between 0 and 1

Given data ,

Let the probability of getting the letter A be P ( A )

Now , the word is given as S = { "MATHEMATICIAN " }

The number of letters in the word S = 13 letters

The number of letter A in the word = 3 A's

So , probability of getting the letter A , P ( A ) = number of letter A in the word / number of letters in the word S

On simplifying , we get

The probability of getting the letter A , P ( A ) = 3/13

Hence , the probability is 3/13

Answer:

Circumference shares the same concept with perimeter.

First, let's use the formula for the circumference of a full circle.

C = 2πr

Where 'π' stands for pi(22/7 or 3.14) and 'r' stands for the radius.

or

C = πd

Where 'π' represents pi(22/7 or 3.14) and 'd' stands for the diameter.

But, we are trying to find a semi-circle's circumference. So, what you would do is that you would divide the whole product of the formula by 2.

For this, I'll be using this formula C = πd. Though, since we are dividing by 2 we can apply that to the diameter and make it a radius in our formula.

So the 'd' in the formula will be 'r'.

Now, let's find the radius.

D/2 = R

So,

35/2 = 17.5

Use this in our formula:-

C = πr

C = 3.14(17.5)

C = 54.95 inches.

Answer:

1. x = 3

2. s = 11

3. z = 14

4. y = 2

Step-by-step explanation:

1. x + 9 = 12

12 - 9 = x

⇒ x = 3

2. s - 1 = 10

10 + 1 = s

⇒ s = 11

3. 3 = z - 11

z - 11 = 3

11 + 3 = z

⇒ z = 14

Answer:

⅛

Step-by-step explanation:

There are two sides of a coin which means that the profanity of getting one side of the coin is ½.

There are 14 candies in total of which 7 are red, meaning that the probability of getting a red candy is 7/14, which is the same as ½.

There are 6 sides to a die, of which 3 sides contain the odd numbers 1,3 and 5. This would mean that the probability of getting an odd number on the die is 3/6, which is the same as ½.

Now to work out the probability of getting a red candy, a heads and an odd number on the die, you have to times the probability of each together to get you final answer.

So it will be, ½×½×½=⅛
