<h2>Value of f(-10) is 1100</h2>

Step-by-step explanation:

Given that f(x) = x² - x³

Here we need to find f(-10).

f(-10) = (-10)² - (-10)³

f(-10) = 100 - (-1000)

f(-10) = 100 + 1000

f(-10) = 1100

Value of f(-10) is 1100

A bag contains 3 red marbles and 4 blue marbles.

vazorg [7]

The probability of getting two marbles of the same colour is 25/49.

<h3>What is defined as the probability?</h3>

Probability is simply the likelihood of something occurring. When we are uncertain about the outcome of an event, we can discuss the probabilities of various outcomes—how likely they are.
Statistics is the study of events governed by probability.

The formula for finding the probability is;

Probability(event) = favourable outcome/total outcome

Total red marbles in the bag = 3.

Total blue marbles in the bag = 4.

Total marbles = 7.

As, the case is with replacement total marble will remain same after the drawn of first marble.

The probability that first marble be red = 3/7

The probability that first marble be red = 3/7

The combine probability getting red marble = 3/7 × 3/7 = 9/49

The probability that first marble be blue = 4/7

The probability that first marble be blue = 4/7

The combine probability getting blue marble = 4/7 × 4/7 = 16/49.

The condition for OR either red or blue marble be drawn.

Thus,

The combine probability getting marble of same colour = 9/49 + 16/49.

Therefore, the combine probability getting marble of same colour = 25/49.

A car rental costs a fee of $150 plus $35 per

lutik1710 [3]

Answer:

5 hours

Step-by-step explanation:

We know that Joey spent a total of $325. He first paid the fee of $150. Let's subtract $150 from $325.

$325 - $150 = $175

Now, we know that it costs $35 per hour to rent the car. So, we divide $175 by $35 to find out how many hours Joey rented the car for.

$175 ÷ $35 = 5 hours

A motorboat takes 40 minutes to travel 20 miles downstream. The return trip takes 60 minutes. What is the speed of the current?

FromTheMoon [43]

Let b be the speed of the boat, and c be the speed of the current. Then:
20/b+c=2/3 hr
20/b-c=1 hr
2/3b+2/3c=20
b-c=20
Then:
b+c=30
b-c=20
2b=50
b=25 mph
c=5 mph

A grocery store has received a shipment of apples.There are 15 boxes of apples,and each box contains 17 bags of apples. Each bag

gogolik [260]

Answer:

There are 3060 apples in the shipment.

Step-by-step explanation:

Given:

Number of boxes of apples = 15

Each boxes contains = 17 bags of Apples

hence 15 boxes will contains = Number of bags of apples in 15 boxes.

By Using Unitary Method we get;

Number of bags of apples in 15 boxes = $15\times 17= 255 \ bags \ of \ apples$

Hence 15 boxes contains = 255 bags of apples.

Also Given:

Each bag contains = 12 apples

255 bags contains = Number of apples in 255 bags

By Using Unitary Method we get;

Number of apples in 255 bags = $255\times12= 3060 \ apples$

Hence 255 bags of apples contains = 3060 apples.

Hence There are 3060 apples in the shipment.
