Randy drew a rectangle inside another with the size shown below on a piece of paper. He places the paper outside during a light rain. What is the approximate probability that a raindrop that lands on the paper will fall outside the shaded region?

Answers

Answer:

[tex]Probability = 84\%[/tex]

Step-by-step explanation:

First, calculate both areas

[tex]Area = Length * Width[/tex]

The area of the outer rectangle is:

[tex]Big\ Area = 20 * 25[/tex]

[tex]Big\ Area = 500cm^2[/tex]

The area of the small rectangle is:

[tex]Small\ Area = 10 * 8[/tex]

[tex]Small\ Area = 80cm^2[/tex]

The area outside the small rectangle is:

[tex]Outside = Big - Small[/tex]

[tex]Outside = 500cm^2 - 80cm^2[/tex]

[tex]Outside = 420cm^2[/tex]

So, the probability that it falls outside the paper inside is:

[tex]Probability = \frac{Outside}{Big\ Area}[/tex]

[tex]Probability = \frac{420cm^2}{500cm^2}[/tex]

[tex]Probability = \frac{420}{500}[/tex]

[tex]Probability = 0.84[/tex]

Express as percentage:

[tex]Probability = 0.84*100\%[/tex]

[tex]Probability = 84\%[/tex]

f(x)= 3x and g(x)= -x+4, so f(g(2))=?

Answers

Answer: 6

Step-by-step explanation: first, you plug in 2 into the g(x) function. So, replace x with 2 in the second function g(x). -2 + 4 = 2. Then take that answer (2), and plug that into the x for f(x). 3 x 2 = 6

Answer:

[tex]f(g(2))=6.[/tex]

Step-by-step explanation:

We have [tex]g(x)=-x+4 \Rightarrow g(2)=-2+4=2[/tex]

Since [tex]f(x)=3x[/tex] then [tex]f(g(2))=f(2)=3.2=6.[/tex]

Answers

Answer:

√{1254×1254}=√1254²=±1254 is your answer

Step-by-step explanation:

1) Simplify 1254 × 1254 to 1572516.

[tex] \sqrt{1572516} [/tex]

2) Since 1254 × 1254 = 1572516, the square root of 1572516 is 1254.

[tex]1254[/tex]

Therefor, the answer is 1254.

Solve the system of equations -3x+7y=-18 and 4x-4y=8 by combining the equations

Answers

Answer:

(-4, -3)

Step-by-step explanation:

Using elimination by addition and subtraction works best here.

Suppose we decide to eliminate x temporarily. To do this, we multipy the first row by 4, obtaining

-12x + 28y = -72

4x - 4y = 8

Next, multiply the second row by 3, obtaining the "equivalent system"

-12x + 28y = -72

12x - 12y = 24

Combining these equations, column by column, we get:

16y = -48. So y = -3.

Now let's find x. Substitute -3 for y in the second equation:

4x - 4(-3) = 8, or

4x + 12 = 8, or

4x = 8 - 12 = -4. This tells us that x = -4.

The solution is thus (-4, -3).

how would i show work on this? A DATA set shows the number of minutes each of 153,477 students takes to complete a
reading test. The median completion time is 110 minutes. The interquartile range is 34. Which
statement about the completion times is most likely to be true?
Of these students, 25% complete the test in 110 minutes or less.
B. Of these students, 50% complete the test in 110 minutes or less.
C. Of these students, 75% complete the test in 127 minutes or less.
D. Of these students, 75% complete the test in 144 minutes or less.

Answers

Answer:

Step-by-step explanation:

half of IQR is 17

110 + 17 = 127 (this represents the 3rd quartile)

110 - 17 = 93 (this represents the 1st quartile)

The 3rd quartile represents 75% of the data so 75% of the students complete the test in 127 minutes or less

Need help with the correct answer please! Thank you. Which two triangles are congruent by the SSS Theorem? I picked D but that is the wrong answer.

Answers

Answer:

Step-by-step explanation:

RQ=TV

QS=VU

RS=TU

While proving that 2 triangles are congruent you have to consider the same side for both triangles.

The mistake you made was that you presumed that since both have equal sides they are equal,

In a sense that is true but you have align it in the correct way, in option D) it shows RQ is equal to TU which is wrong, RQ is equal to VT, you have align it in a proper way.

B) ΔRQS ≅ ΔTVU here it is align perfectly to be matched

three odd consecutive integers are such that 3 times the smallest is 9 more than twice the largest .find the three numbers

Answers

Answer: 17, 19, 21

Step-by-step explanation:

Three consecutive odd numbers: x, x+2, x+4 (since odd numbers occur every other number)

Just to show you that the numbers are x, x+2, and x+4, just say x is 13 then x+2 is 15 and x+4 is 17 (3 consecutive odd numbers)

Now the second equation:

3x = 2(x+4) + 9

three times smallest number (which is x) is equal to 2 times the largest number (x+4) plus 9

Now solve

3x = 2(x+4) +9

3x = 2x + 8 + 9

3x = 2x + 17

x = 17

x+2 = 19

x+3 = 21

A triangle has sides with lengths of 7 millimeters, 14 millimeters, and 15 millimeters. Is it a right triangle

Answers

Answer:

Step-by-step explanation:

Property of a right triangle,

(Hypotenuse)² = (leg 1)² + (leg 2)²

substituting 16 and 12 into 'a' and 'b' you get 16^2 + 12^2 = c^2

256 + 144 = c^2

400 = c^2 (square root each side to get ride of the square)

c = 20cm

2. doing the same thing you get c = 22.36 in
