Answer:

Step-by-step explanation:

i think i dont know that much

The probability that the basketball player makes his first three-point shot on the third attempt is 0.38.

A discrete probability distribution known as a geometric distribution may be used to describe the likelihood of experiencing success for the first time following a string of failures. Up until the first success, a geometric distribution can undergo an infinite number of trials.

The number of separate trials necessary to achieve success is described by the geometric distribution,

which is a probability distribution.

In this scenario, the basketball player's three-point accuracy rate is 25%, which indicates that the probabilities of success (hitting a three-point shot) and failure (missing a three-point shot) are 0.25 and 1-p, respectively.

The likelihood that the basketball player will make his first three-point shot on the third try,

according to the geometric distribution formula, is:

P(x = 3) = (1-p)⁽³⁻¹⁾ × p

           = (0.75)²  × 0.25

           = 0.38

Hence,  there is a 38% probability that the basketball player will make his first three-point shot on the third attempt.

Answer:

x = 0

y = 3/7

(4)

x = 6

y = -11

Step-by-step explanation:

the beginning was right, but get mistake was then to add the 2 equations but the parts with the y terms she suddenly subtracted.

no, one operation for everything. and then maybe another operation (and again for everything present).

so, some would multiply by -2 and then truly add.

or, as we will do it now to refuse as much as possible from your friend's work, we multiply by 2 and then SUBTRACT !

5x + 7y = 3

3x + 14y = 6

multiply the first equation by 2 and then subtract the second one.

10x + 14y = 6

- 3x + 14y = 6

-----------------------

7x + 0 = 0

=>

x = 0

then we use this e.g. in the first equation to get y :

5×0 + 7y = 3

7y = 3

y = 3/7

10x + 3y = 27

3x - 5y = 73

let's go e.g. for 15y (multiply the fits by 5 and the second by 3)

50x + 15y = 135

+ 9x - 15y = 219

------------------------

59x + 0. = 354

59x = 354

x = 6

10×6 + 3y = 27

60 + 3y = 27

3y = -33

y = -11

It is 18.67031

Step-by-step explanation:

[tex]thats \: it[/tex]

The nearest hundred-thousandth of the number is 18.67031.

To find the nearest hundred-thousandth.

Decimals are the numbers, which consist of two parts namely, a whole number part and a fractional part separated by a decimal point.

If the digit is less than 5, round down the nearest digit. If the digit is more than or equal to 5, round up the nearest digit.

the given number is 18.670308 ,then round up the nearest digit is 18.67031.

So, the nearest hundred-thousandth of the number is 18.67031.

Answer: 7

Step-by-step explanation:

1. multiply both sides by -6 so the -6 on the right side could cancel out and the left side would be -6:  1= a-13/-6 ==> -6=a-13

2. add both sides by 13 so -13 on the right side could cancel out and the left side would be -6+13: -6=a-13 ==> -6+13=a-13+13

3. you know -6+13 equals 7 right? so the answer is a=7

Hey there! I'm happy to help!

We want to get the a all by itself. For me, I always like to have the variable on the left side, so first, let's just flip this around.

[tex]\frac{a-13}{-6} =1[/tex]

What we want to do is get all of the constants (numbers without variables) on the right side. This will leave a all on its own.

We see that the quantity a-13 is being divided by -6. To undo this, we will just multiply both sides by -6. This will cancel out that -6 and get us closer to having the a isolated.

[tex]\frac{a-13}{-6} *-6=1*-6\\\frac{a-13}{1}=-6\\a-13=-6[/tex]

Now we add 13 to both sides to undo the -13 on the left side.

[tex]a-13+13=-6+13[/tex]

[tex]a+0=7\\a=7[/tex]

Answer:

  C)  41

Step-by-step explanation:

The angles of the linear pair are supplementary, so you have ...

  (x +16)° +123° = 180°

  x = 41 . . . . . . . . . . . . . . divide by °, subtract 139

Answer:

x = 41

Step-by-step explanation:

The angles shown are supplementary

Supplementary angles add up to equal 180

This means that x + 16 + 123 = 180

x + 16 + 123 = 180

Solve for x

Combine like terms ( add 16 and 123 )

x + 139 = 180

Subtract 139 from both sides

x = 41

Answer:

22 cubes

Step-by-step explanation:

Hi! I'm happy to help!

Perimeter is the total length of all the sides.

Let's start out with the top left corner and work our way counterclockwise.

For our first segment, we start from the top left corner and go to the bottom left corner, this is a length of 3, let's start our equation:

3+

Next, we are at the bottom left corner, let's go to the bottom right corner. This is a length of 5. Let's expand our equation:

3+5+

Now we are at the bottom right corner, let's go to the top right corner. This is also a length of 3. Let's add that to our equation:

3+5+3+

Now we are at the top right corner, lets go to the top middle right corner, which is to the left one unit. Let's add this:

3+5+3+1+

Now, let's head down 2 units to the inside of our shape.

3+5+3+1+2+

Move toward the center one unit:

3+5+3+1+2+1+

Move up one unit:

3+5+3+1+2+1+1+

Move left one unit:

3+5+3+1+2+1+1+1+

Move down one unit:

3+5+3+1+2+1+1+1+1+

Move left another unit:

3+5+3+1+2+1+1+1+1+1+

Start heading back up 2 units towards the top left corner:

3+5+3+1+2+1+1+1+1+1+2+

Finally, reach back 1 unit to the top left corner:

3+5+3+1+2+1+1+1+1+1+2+1=

Let's solve:

3+5+3+1+2+1+1+1+1+1+2+1=

8+3+1+2+1+1+1+1+1+2+1=

11+1+2+1+1+1+1+1+2+1=

12+2+1+1+1+1+1+2+1=

14+1+1+1+1+1+2+1=

15+1+1+1+1+2+1=

16+1+1+1+2+1=

17+1+1+2+1=

18+1+2+1=

Answer:

A

Step-by-step explanation:

You are given that x - 3 = 8

It's an equation. The first thing you do is add or subtract when you are learning how to handle equations. This is a level 1 equation. That means that the solution is just to add or subtract something.

In this case, x has 3 taken away from it. So you have to get x by  itself. The way to do that is to add 3. Then the -3 on the left disappears.

x - 3 + 3 = 8+3

x = 11

The answer is A

Answer:

don't know actually but I can elaborate the solution

Step-by-step explanation:

Answer:

[-5, 2]

Step-by-step explanation:

We have to find the interval for which f(x) <= 0, the interval is [-5, 2].

1.

Paul's present age = x

John's present age = 18

Paul's age 4 years ago = x - 4

John's age 4 years ago = 18 - 4 = 14

Also,

Paul's age four years ago was twice that of John's age four years ago.

Therefore,

Paul's age 4 years ago = 2(14)

= 28

Paul's age 4 years ago = x - 4 = 28

x - 4 = 28

x = 28 + 4

x = 32

Therefore, the present age of Paul is 32.

Cost of one bottle of milk = $3.2

Cost of five bottles of milk = $3.2 × 5 = $15

Cost of four bottles of juice = $15 - $4.4

= $10.6

Cost of one bottle of juice = x

= Cost of four bottles of juice

4

= 10.6

4

= 2.56

Therefore, one bottle of juice costs $2.56.

3.

Savings spent on personal ornaments = 1/8

Savings spent on clothing = 5/6

Total savings spent = 1/8 + 5/6

= 3/24 + 20/24

= (3+20)/24

= 23/24

Savings left = 1/24 = $130

Total amount of savings = x

As 130 is one part of the total savings,

Total amount of savings =

x = 130 × 24

x = 3120

Therefore, original amount of savings is $3120.
