Tom has 12 cards with the numbers 1 to 12 on them.
Anna71 [15]

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.

The function y = x 2 - 10x + 31 has a ____
katrin [286]

Answer:

Option B. minimum is correct for the first blank

Option C. 6 is correct for second blank.

Step-by-step explanation:

In order to find the maxima or minima of a function, we have to take the first derivative and then put it equal to zero to find the critical values.

Given function is:

f(x) = x^2-10x+31

Taking first derivative

f'(x) = 2x-10

Now the first derivative has to be put equal to zero to find the critical value

2x-10 = 0\\2x = 10\\x = \frac{10}{2} = 5

The function has only one critical value which is 5.

Taking 2nd derivative

f''(x) =2

f''(5) = 2

As the value of 2nd derivative is positive for the critical value 5, this means that the function has a minimum value at x = 5

The value can be found out by putting x=5 in the function

f(5) = (5)^2-10(5)+31\\=25-50+31\\=6

Hence,

<u>The function y = x 2 - 10x + 31 has a minimum  value of 6</u>

Hence,

Option B. minimum is correct for the first blank

Option C. 6 is correct for second blank.
