which statements are true regarding the equation? sorry it's blurry it's the best photo i could get of it all.
12345 [234]

Given that 2 large puzzle costs $16 then

2l=16

or

l=8

That means cost of 1 large puzzle = $8


Given that 3 small puzzle costs $15 then

3s=15

or

s=5

That means cost of 1 small puzzle = $5


Now we will use this information to find the correct choice.

---

First choice is <u>wrong </u>as coefficient 8 is with 8l so that gives cost of 1 large not small puzzle.

---

Second choice is <u>correct </u>as coefficient 8 is with 8l so that gives cost of 1 large puzzle.

---


Third choice is <u>correct </u>as coefficient 5 is with 5s so that gives cost of 1 small puzzle.

---


Fourth choice is <u>Wrong </u>as coefficient 5 is with 5s so that gives cost of 1 small not large puzzle.

---


Fifth choice is <u>wrong </u>as constant 128 gives total cost of not the total number of puzzles.

PLEASE HELP ASAP I always give brainliests!
nlexa [21]

first to find average age add all the ages divide by number of ages 4

5+4=9

9+6=15

15+39=54

54/4=13.5

For standard deviation find the mean/average

13.5

then subtract the mean from each number/age

5-13.5=-8.5

4-13.5=-9.5

6-13.5=-7.5

39-13.5=25.5

then square each number

-8.5^2=-72.25

-9.5^2=-90.25

-7.5^2=-56.25

25.5^2=650.25

then find the mean/average of the new numbers

-72.25+-90.25+-56.25+650.25=431.5

431.5/4=107.85

then take the square root of the new mean/average

\sqrt{ 107.875}\\10.38628903...
