Answer:
Step-by-step explanation:
Let "x" be the number.
Product of 6 and x (6*x), increased by 4 =
Product of 12 and x, (12*x), decreased by 20 = .
Set both expressions equal to each other and solve for x as shown below:
(equation)
Subtract 12 from both sides
Subtract 4 from both sides
Divide both sides by -6
Answer:
yes
Step-by-step explanation:
If this is a parabolic motion equation, then it is a negative parabola, which looks like a hill (instead of a positive parabola that opens like a cup). Your equation would be h(t)= -16t^2 + 20t +3. That's the equation for an initial velocity of 20 ft/s thrown from an initial height of 3 ft. And the -16t^2 is the antiderivative of the gravitational pull. Anyway, if you're looking for the maximum height and you don't know calculus, then you have to complete the square to get this into vertex form. The vertex will be the highest point on the graph, which is consequently also the max height of the ball. When you do this, you get a vertex of (5/8, 9.25). The 9.25 is the max height of the ball.
Answer:
B. 0.132
Step-by-step explanation:
For each time the dice is thrown, there are only two possible outcomes. Either it lands on a five, or it does not. The probability of a throw landing on a five is independent of other throws. So we use the binomial probability distribution to solve this question.
Binomial probability distribution
The binomial probability is the probability of exactly x successes on n repeated trials, and X can only have two outcomes.
In which is the number of different combinations of x objects from a set of n elements, given by the following formula.
And p is the probability of X happening.
Timothy creates a game in which the player rolls 4 dice.
This means that
The dice can land in 6 numbers, one of which is 5.
This means that
What is the probability in this game of having exactly two dice or more land on a five?
In which
So the correct answer is:
B. 0.132
