Answer:
red over blue
Step-by-step explanation:
Set the function to equal zero:
To find the zeros, or solutions, to this problem, we will use the quadratic formula:
Plug the values into the equation:
Solve for both plus and minus:
The question cannot use a negative value for x, as the diver cannot dive a negative distance from the board.
The answer is
'<span>
x = 5; the diver hits the water 5 feet away horizontally from the board', because x represents the horizontal distance away from the board.</span>
Answer:
a = - 25
Step-by-step explanation:
Given that:
4a+6+16=-9(2+12a)-10(1-11a)
By simplifying:
- Adding like terms and multiplying constants into the bracket
- Negative sign will change the signs in the brackets
4a + 22 = -18 - 108a- 10 +110a
4a + 22 = -28 + 2a
- Taking terms with "a" to left side and others to right
- Signs of transferred terms will be changed
4a - 2a = -28 - 22
- Both terms on right side have negative sign so they wil be added and answer will have negative sign.
2a = -50
- Dividing both sides by 2 we get
a = -50/2
- Reducing to lowest term (dividing both by 2)
a = -25/

Answer:
Hence the probability that she paid cash is 0.105
Step-by-step explanation:
P(cash) = 0.3
P(credit card ) = 0.3
P(debit card ) = 0.4
P ( more than $50 | cash ) = 0.2
P (more than $50 | credit card ) =0.9
P (more than $ 50 |debit card ) = 0.6
P ( more than $50) = P ( more than $50 | cash )* P (cash) + P (more than $50 credit card ) * P(credit card ) + P (more than $ 50 |debit card )* P(debit card )
= 0.2 * 0.3 + 0.9 * 0.3 + 0.6* 0.4
= 0.57
P ( more than $50) = P ( more than $50 | cash )* P (cash) / P ( more than $50)
= 0.2* 0.3 / 0.57
= 0.105
