A box contains four tiles 1,4,5 and 8 as shown. Kelly chooses one time places it back in the box then chooses a second tile. What is the probability that the sum of the two chosen tiles is greater than 7?

Answers

Answer 1

Answer:

the answer to that question is 11/16

Answer 2

Using the probability principle, the probability of picking two tiles which sums above 7 is 11/16.

Recall :

Probability = required outcome / Total possible outcomes

The only way to choose two tiles which sums up to a number greater than 7 would be :

(1,8), (8, 1), (4, 5), (5,4), (4, 8), (8,4), (5,8), (8,5), {4, 4}, {5, 5}, {8, 8}

Since selection is performed with replacement ;

Total possible outcome = sample size = = 16

The probability of choosing two tiles whose sum is greater than 7 ;

11/16 =

Hence, probability of choosing tiles with a sum greater than 7 is 11/16

Therefore, the probability of picking two tiles which sums above 7 is 11/16.

HELP! i’m confused! question is in the picture

Answers

Answer:

[-6,-3]

Step-by-step explanation:

So we have the compound inequality:

[tex]2x+7\leq x+4\leq 3x+16[/tex]

Let's solve for each of the inequalities:

1)

We have:

[tex]2x+7\leq x+4[/tex]

Subtract x from both sides:

[tex]x+7\leq 4[/tex]

Subtract 7 from both sides:

[tex]x\leq -3[/tex]

So that's one of our answers.

2)

We have:

[tex]x+4\leq 3x+16[/tex]

Subtract 3x from both sides:

[tex]-2x+4\leq 16[/tex]

Subtract 4 from both sides:

[tex]-2x\leq 12[/tex]

Divide both sides by -2. Since we're dividing by a negative, flip the sign:

[tex]x\geq -6[/tex]

Therefore, our entire answer is:

[tex]-6\leq x\leq -3[/tex]

This means all values in between -3 and -6 including -3 and -6.

In interval notation, this is:

[tex][-6,-3][/tex]

So, A is -6.

And B is -3.

And we're done :)

If the length of a rectangle is increased by 120%, and its width is decreased by 20%, what is the percentage change in the area of the rectangle? (rea=length*width)

Answers

Answer:

The area of the rectangle is increased in 76 percent.

Step-by-step explanation:

The area of a rectangle ([tex]A[/tex]) is represented by the following formula:

[tex]A = w\cdot l[/tex]

Where:

[tex]w[/tex] - Width.

[tex]l[/tex] - Length.

If length is increased by 120 %and width is decreased by 20 %, the percentage change in the area of the rectangle is: ([tex]l = 2.2\cdot l_{o}[/tex], [tex]w = 0.8\cdot w_{o}[/tex])

[tex]A = (2.2\cdot l_{o})\cdot (0.8\cdot w_{o})[/tex]

[tex]A = (2.2)\cdot (0.8)\cdot w_{o}\cdot l_{o}[/tex]

[tex]A = 1.76\cdot A_{o}[/tex]

The area of the rectangle is increased in 76 percent.

A piece of wood has a width of 5 cm and a height of 10 cm. Its volume is 100 cm? What is the length of the wood?

10,000 cm

2 cm

515 cm

50 cm

Answers

Answer:

The length of a piece of wood is 2 cm.

Given:

volume = 100 cm³

width = 5 cm

height = 10 cm

length = ?

Volume is computed by multiplying the length, width, and height of an object.

Volume = length * width * height

100 cm³ = length * 5 cm * 10 cm

100 cm³ = length * 50 cm²

100 cm³ / 50 cm² = length

2 cm = length

to check:

100 cm³ = 2 cm * 5 cm * 10 cm

100 cm³ =  10 cm² * 10 cm

100 cm³ = 100 cm³

JK + KL = JL , substitute values

2x + 1 + 6x = 81, that is

8x + 1 = 81 ( subtract 1 from both sides )

8x = 80 ( divide both sides by 8 )

x = 10

Thus JK = 2x + 2 = 2(10) + 1 = 20 + 1 = 21

KL = 6x = 6 × 10 = 60

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

16

JK + KL = JL , substitute values

2x + x + 2 = 5x - 10 , that is

3x + 2 = 5x - 10 ( subtract 3x from both sides )

2 = 2x - 10 ( add 10 to both sides )

12 = 2x ( divide both sides by 2 )

6 = x

Thus

JK = 2X = 2 × 6 = 12

KL = x + 2 = 6 + 2 = 8

JL = 5x - 10 = 5(6) - 10 = 30 - 10 = 20
