Answer:

3, 4, and 5

Step-by-step explanation:

To put it simply, 3 + 4 + 5 = 12 and the numbers are consecutive, next to each other.

The method:

The three consecutive numbers could be called x, x + 1, and x + 2 and we know that x + x + 1 + x + 2 = 12

This can be simplified to 3x + 3 = 12. Next, subtract 3 from both sides to get 3x = 9. Now, divide both sides by 3 to get x = 3.

This means that the first number is 3 and the other numbers are 4 (3 + 1) and 5 (3 + 2).

Hope this helps!

Answer:

The numbers are 3, 4 and 5.

Step-by-step explanation:

<u>Let's name the three consecutive number x, x + 1, and x + 2.</u>

=> x + x + 1 + x + 2 = 12
=> 3x + 3 = 12
=> 3x = 9
=> x = 3

<u>Now, just substitute the value of x into all the numbers to get your answers.</u>

=> x, x + 1, x + 2
=> 3, 3 + 1, 3 + 2
=> 3, 4, 5

Hence, the numbers are 3, 4 and 5.

A basketball player makes 70% of his free throws the random numbers below represent 20 trials for a simulation let the numbers 0

Nesterboy [21]

Answer:

40%

Step-by-step explanation:

Given the result of the simulation below:

(5,5) (0,6) (9,6) (7,4) (9,1) (7,3) (0,4) (9,3) (2,9) (1,4)

(6,8) (5,3) (1,7) (1,7) (1,8) (3,5) (7,2) (2,1) (0,6) (1,8)

n(S)=20

The numbers 0 to 6 represent a made free throw .
The numbers 7 to 9 represent a missed free throw.
Therefore, any result containing 7 to 9 does not satisfy our requirement that the player makes both throws.

Let Event A be the event that the player made both throws

The pairs in which the player made both throws are:

(5,5) (0,6) (0,4) (1,4) (5,3) (3,5) (2,1) (0,6)

n(A)=8

Therefore:

$P(A)=\frac{n(A)}{n(S)}=\frac{8}{20}=0.4\\$

The probability that the player made both throws is 40%.

Lines d, e, and f are parallel. That means they have the same slope. Each of these lines has a slope of −3. Enter numbers to com

Sloan [31]

Answer:

Line d : y = -3x - 3

Line e : y = -3x - 2

Line f : y= -3x + 2

Step-by-step explanation:

Given that,

The slope of each line is -3.

Now,

We know that,

Equation of line is represented by y = mx + c

where m is the slope and c is the y-intercept.

Now,

Given that,

Line d goes through (0, - 3) and (- 1, 0).

So,

y-intercept of Line d is -3

∴ we get

Equation of Line d is : y = -3x -3

Now,

Given that,

Line e goes through (-1, 2) and (0, -2).

So,

y-intercept of Line e is -2

∴ we get

Equation of Line e is : y = -3x - 2

Now,

Given that,

Line f goes through (0, 2) and (1, -1).

So,

y-intercept of Line e is 2

∴ we get

Equation of Line f is : y = -3x + 2

Let f(x) = x2 - 81. Find f-1(x).

dusya [7]

This is equivalent to finding a function g in which $g(x^2-81)=x$ .

We simply reverse the actions of the initial function by adding 81 back and taking the square root. Therefore, $f^{-1}(x)=\sqrt{x+81}$ .
