Answer:

Slope is positive for all x, so always increasing

Step-by-step explanation:

Increasing/decreasing depends on the slope of the function, which is f'

f'(x) = 9x² + 18x + 25

If f'(x) > 0 for all x, then his claim is correct (increasing for all x)

If there's even 1 x-value for which f'(x) is not positive, his claim is incorrect

f'(x) is a quadratic function.

9x² + 18x + 25

9(x² + 2x) + 25

9(x² + 2(x)(1) + 1² - 1²) + 25

9(x + 1)² - 9 + 25

9(x + 1)² + 16

Since the minimum value of f' is 16, it's always positive.

Hence, the claim is correct

Answer: 2/9 or 0.22

Step-by-step explanation:

Probability = number of possible outcomes/ number of total outcomes

From the given question, total number of outcomes is 18, which the the sum of all the horses in the stable.

P(brown) = number of brown horses/ total number of horses

= 4/18, simplified to 2/9 as s fraction

= 0.22

I hope this helps.

At a museum cafe you can get a pre-made boxed lunch with a sandwich, fruit, and drink for only $3.
Anastasy [175]

Given that sandwiches are made with either turkey or ham.

Prob for turkey or ham = 1/2

The fruit can be either apple or orange. Hence p(apple) = p(orange) =12

Drinks can be either bottled water or juice

P(water) = P(juice) = 1/2

We find that sandwiches, fruits, and drinks are mutually independent of each other.

Hence the probability you will get an orange and not get juice in your box

Prob (you get an orange and bottled water)

= Prob (orange) *Prob (bottled water) (since the two are independent

= 1/2 (1/2)= 1/4

Hence answer is 0.25
