I got zero, but that’s wrong.

Answer:

Expected value is 4,000

Step-by-step explanation:

To find expected value ⇒ multiply the value by it's probability

40% × ( -25,000 ) = - 10,000

Breaking means neither add nor subtract a given amount

20% × 0 = 0

35% × 40,000 = 14,000

∴ Expected value = -10,000 + 14,000 = 4,000

LOSS:                   -10,000

BREAK EVEN:       0

WIN:                       14,000

Expected value is 4,000

<em>hope this helps....</em>

Can someone help with this please? Will mark brainliest

Answer:

25 slugs

Step-by-step explanation:

If this is a physics-based problem, which it appears to be, then the formula for finding mass is

w = mg, where w is the weight, m is the mass, and g is acceleration due to gravity.  We have our weight and our gravity, so

800 = m(32) so

m = 800/32 and

m = 25 slugs

This answer does not include significant digits.  If it needed to, then your answer would be 30 slugs.

Can someone help me thank youuu!!!

Answer:

D.

Step-by-step explanation:

cos is positive and sin is negative

=>

it must be in quadrant IV.

you remember, 1 = sin² + cos²

1 = sin² + (3/5)² = sin² + 9/25

25/25 = sin² + 9/25

16/25 = sin²

sin = 4/5 or -4/5

and as sin of this angle is < 0, our solution is -4/5
