X is the input and y is the output, "more" indicates addition, so 11 more than the input equals x + 11. Answer: y = x + 11
We'll let x represent the weight of Ian's dog.
So we can make the formula Ian's dog (x) + Stephen' dog (5x) = 72
So:
x+5x=72
6x=72
x=12
So ian's dog is 12 pounds, but we're trying to find stephen's dog (5x)
We need to multiply x by 5 so:
5(12)=60
Therefore, Stephen's dog is 60 pounds
The <em>correct answer</em> is:
x³ = 27/125; and
x = 3/5.
Explanation:
Reducing the voltage 3 times would result in multiplying the unknown voltage, x, by itself 3 times; this gives us
x³.
The current voltage is 27/125; this gives us the equation
x³ = 27/125.
To solve this, take the cubed root of both sides:
∛(x³) = ∛(27/125)
x = (∛27)/(∛125)
x = (∛(3*3*3))/(∛(5*5*5))
x = 3/5
Answer:
a) true
Step-by-step explanation:
There are 13 heart-suit cards in a 52 card deck.
Since cards are returned to the deck after each pick, all of the 15 events are independent and have the same likelihood of occurring. Therefore, this experiment follows a binomial distribution with the following properties:
Number of events (n) = 15
Probability of success (Picking a heart) = 13/52 = 1/4
Probability of failure (Not picking a heart) = 39/52 = 3/4
In conclusion, the statement provided is true.
