Answer:
distributive property
Step-by-step explanation:
Distributive property says that x(y + z) = (x*y) + (x *z)
Answer:
there are no choices
Step-by-step explanation:
Answer:
H(x) = 0.85x -2.00
Step-by-step explanation:
The original price of an item, x dollars, is discounted by 15%.
Let x be the original price of an item
15% =0.15 discount , so discounted amount is 0.15x
Now we subtract discounted amount from original amount
x - 0.15x = 0.85x
A coupon for $2.00 off is applied to the discounted price.
$2.00 is off, so we subtract 2
Function becomes H(x) = 0.85x -2.00
Answer:
It would take the balloon 2 seconds to hit the ground
Step-by-step explanation:
They give you the actual formula of the height of the ballon as a function of time in seconds, with all the initial conditions specified in the equation, therefore all you need to do is find the time that it takes for the balloon to reach a height of zero (0) feet, making h=0 and solving for t in a quadratic equation:
where we have factored out the trinomial as a product of two simple binomials. For such product to be zero, either t=2 seconds or t=-3 seconds. Since the time cannot be a negative number, the only viable solution we found is t=2 seconds.
Answer:
Step-by-step explanation:
Let x be a random variable representing the number of registered voters in the congressional district. This is a binomial distribution since the outcomes are two ways. It is either a randomly selected registered voter is a conservative or not. The success would be that a randomly selected voter is a conservative. The probability of success, p = 60/100 = 0.6
The probability of failure, q would be 1 - p = 1 - 0.6 = 0.4
Given n = 10, we want to determine P(x = 4)
From the binomial distribution calculator,
P(x = 4) = 0.11
