The following stem-and-leaf plots compare the ages of 30 actors and 30 actresses at the time they won the Oscar award for Best A
stealth61 [152]

The image of the stem-and-leaf plots is in the attachment.

Answer: (a) 31 years; (b) 59 years; (c) 56 years

Step-by-step explanation: Steam and leaf is a table that shows the digits of the data value split into a "stem", which represents the first digit, and a "leaf", which is the last digit.

For example, the first row of the table in the attachment, indicate a "stem" 2 and the first number of a "leaf" is 1, so the actress has 21 years.

(a) According to the table, the youngest actor to win an Oscar has a "stem" 3 and the first "leaf" from the right is 1, so the actor has 31 years.

(b) The oldest actress is 80 and the youngest is 21, so difference is:

80 - 21 = 59

The difference is 59 years.

(c) The oldest age shared by 2 actors is 56 years.

I need help with these.
sattari [20]

Answer:

See below.

Step-by-step explanation:

1.

5^2 + 12^2 = x^2

25 + 144 = x^2

169 = x^2

x = 13

2.

3^2 + x^2 = [sqrt(10)]^2

9 + x^2 = 10

x^2 = 1

x = 1

3.

1^2 + x^2 = 4^2

1 + x^2 = 16

x^2 = 15

x = sqrt(15)

4.

[sqrt(27)]^2 + x^2 = 6^2

27 + x^2 = 36

x^2 = 9

x = 3

5.

15/5 = c/sqrt(29)

5c = 15 * sqrt(29)

c = 3sqrt(29)

6.

26/13 = x/12

2 = x/12

x = 24

Let's find.

\\ \rm\Rrightarrow (-2x^3+x-5)(x^3-3x+4)

\\ \rm\Rrightarrow x^3(-2x^3+x-5)-3x(-2x^3+x-5)+4(-2x^3+x-5)

\\ \rm\Rrightarrow -2x^6+x^4-5x^3+6x^4-3x^2+15x-8x^3+4x-20

\\ \rm\Rrightarrow -2x^6+7x^4-13x^3-3x^2+19x-20

#b

Yes

It's because multiplication law states that ab=ba

-3(4x-6)=7-12x(solve)(show work)
erma4kov [3.2K]

Hi there!  

»»————- ★ ————-««

I believe your answer is:  

There is no solution to the equation.  

»»————- ★ ————-««  

Here’s why:

⸻⸻⸻⸻

\boxed{\text{Calculating the Answer...}}\\\\-3(4x-6)=7-12x\\-------------\\\rightarrow -12x+18 = 7 - 12x\\\\\rightarrow -12x + 18 - 18 = 7 - 18 -12x\\\\\rightarrow -12x=-12x-11\\\\\rightarrow-12x+12x = -12x+12x - 11\\\\\rightarrow 0 = -11\\\\\boxed{\text{This is a \underline{contradiction}. There is no solution.}}

⸻⸻⸻⸻

»»————- ★ ————-««  

Hope this helps you. I apologize if it’s incorrect.
