Tom has 12 cards with the numbers 1 to 12 on them.

Mathematics
1 answer:
Anna71 [15]3 years ago
8 0

Answer:

5/12

Step-by-step explanation:

Given that,

Total no of cards = 12 with numbers 1 to 12

We need to find the probability of getting 5.

Probability = favourable outcomes/total no of outcomes

Favourable outcomes is 5 as it come one time

Total no of outcome = 12 (total no of cards)

So,

P(5)=\dfrac{5}{12}

Hence, the probability of getting 5 is 5/12.

Consider the leading term of the polynomial function. What is the end behavior of the graph? 2x^7-8x^6-3x^5-3
jeyben [28]

Answer:

\lim_{x \to -\infty}y = -\infty\\ \lim_{x \to \infty}y = \infty

Step-by-step explanation:

Due to the fact that the degree of the polynomial is odd, we know one end must go up and the other down. Because the leading coefficient is even, we know that as x approaches negative infinity, y approaches negative infinity as well. As x approaches positive infinity, y approaches positive infinity.

One root of f(x) = x + 10x2 – 25x – 250 is x = -10. What are all the roots of the function? Use the Remainder Theorem.
Natalka [10]

Answer:

-10

-5

5

Step-by-step explanation:

From the answers given, you probably mean f(x) = x^3 + 10x2 – 25x – 250

The Remainder Theorem is going to take a bit to solve.

You have to try the factors of 250. One way to make your life a lot easier is to graph the equation. That will give you the roots.

The graph appears below. Since the y intercept is -250 the graph goes down quite a bit and if you show the y intercept then it will not be easy to see the roots.

However just to get the roots, the graph shows that

x = -10

x = - 5

x = 5

The last answer is the right one. To use the remainder theorem, you could show none of the answers will give 0s except the last one. For example, the second one will give

f((10) = 10^3 + 10*10^2 - 25*10 - 250

f(10) = 1000 + 1000 - 250 - 250

f(10) = 2000 - 500

f(10) = 1500 which is  not 0.

==================

f(1) = (1)^3 + 10*(1)^2 - 25(1) - 250

f(1) = 1 + 10 - 25 - 250

f(1) = -264 which again is not zero
