$4.15n - ($250 + $2.45n)

Now that we have our expression, let's set it greater than or equal to 0

$4.15n - ($250 + $2.45n) >= 0

Let's simplify the left side.

$4.15n - $250 - $2.45n >= 0.

Combine like terms.

$1.7n - $250 >= 0

Add $250 to both sides.

$1.7n >= $250

Divide both sides by $1.7

n >= 148

You would need to make 148 light sabers to make a positive profit.

The probability distribution for a
Klio2033 [76]

Answer:

.3

Step-by-step explanation:

The probability distribution in the second row simply shows the probabilities for each number in the first row.

To find the probability that x is between -5 and 5, you can add the probabilities -5 < x < 5.

P(-5) = 0.15

P(0) = 0.05

P(5) = 0.1

0.15 + 0.05 + 0.1 = 0.3

What is FJ for brainliest
Likurg_2 [28]
Hiiii i just commented but it works now!

THE ANSWER IS: 9

let the length FJ be x

since the triangles are similar, set up a ratio that matches the corresponding sides
so the longest side of the triangle over the shortest side of the triangle

set the ratios equal to each other

to solve for 16+x, multiply 15x15 then divide by x
rewrite that as 225/x = 16+x

solve for x
you’ll get two answers: -25 and 9
since the side length can’t be negative, the answer is 9

boys= 8

girls= 4
