Answer 2

Answer:

The best prediction is that you will pick a green marble approximately 7 times and an orange marble approximately 5 times.

Step-by-step explanation:

If there are 5 orange marbles and 7 green marbles out of a total of 48 marbles, the best prediction for the number of times you will pick a green or an orange marble would still be proportional to the ratio of green and orange marbles.

The ratio of green marbles to the total number of marbles is 7/48, and the ratio of orange marbles to the total number of marbles is 5/48.

To predict the number of times you will pick a green marble, you can multiply the total number of selections (48) by the ratio of green marbles:

48 * (7/48) = 7

Similarly, to predict the number of times you will pick an orange marble:

48 * (5/48) = 5

Therefore, the best prediction is that you will pick a green marble approximately 7 times and an orange marble approximately 5 times.

Answer:

A = plane

B = whale

C = sunken ship

Step-by-step explanation:

The given vertical number line is modelling the positions of objects and animals in relation to sea level.

Sea level is the average height of the surface of the world's oceans, which we use as a reference point to measure the elevation and depth of land and water features on Earth.

From inspection of the given number line:

Position A is above sea level.Position B is just below sea level.Position C is the furthest below sea level.

We have been told that a plane is flying at 8,500 feet above sea level. Therefore, as position A is the only position above sea level, A = plane.

We have been told that a sunken ship is resting at 3,000 feet below sea level, and that directly above the ship, a whale is swimming 1,960 feet below sea level. Therefore, the whale is above the ship. As position B is above position C, this means that B = whale and C = sunken ship.

A is plane b is whale c is sunken ship

Answer:

88 times

Step-by-step explanation:

If the spinner has only green inside the circle, it means that every spin will result in landing on green. Therefore, the best prediction for the number of times it will land on green would be 88, as you spin the spinner 88 times.

88 times

The circle is 100% green so the probability would be 100%

Answer: 4x^3y^2(4 - 6xy^2)

Explanation:
To find the greatest common factor, or GCF, you have to find the number that all of the coefficients can be divided by and all the exponents can be subtracted by (and result in a non-negative exponent.)

In this case, the lowest exponent for x is 3, the lowest exponent for y is 2, and the GCF of -24 and 16 is 4.

Divide the whole equation (still meaning to subtract the exponents if you remember exponent rules) by 4x^3y^2. You then get 4 - 6xy^2.

Always remember to include the GCF on the outside.

So the answer is 4x^3y^2(4 - 6xy^2)

answer : 4x^3y^2 hope this helps for simply : ( 4 - 6xy^2 ) :))

You select a marble without looking and then put it back. If you do this 25 times, what is the best prediction possible for the number of times you will pick a marble that is not blue?

LOOK AT IMAGE

Answers

Answer:

Step-by-step explanation:

Green is 3/5 of the set.

3/5 of 25 is 15.

Answer:

15 times

Step-by-step explanation:

Assuming that you are picking the marbles without replacement, the probability of picking a marble that is not blue is 3/5. This is because there are 3 green marbles and 2 blue marbles in the bag, so out of 5 possible outcomes, 3 of them are not blue.

To find the best prediction for the number of times you will pick a marble that is not blue in 25 trials, you can multiply the probability by the number of trials. This gives you 3/5 x 25 = 15. So, the best prediction is that you will pick a marble that is not blue 15 times out of 25.

Answer:

1/2 or 0.5.

Step-by-step explanation:

To calculate the probability of two cards chosen not including T, we need to determine the number of favorable outcomes (cards not including T) and the total number of possible outcomes.

From the provided sample space table:

The favorable outcomes for two cards not including T are:

P, M

P, P

P, R

P, M

R, M

R, P

R, R

R, T

There are 8 favorable outcomes.

The total number of possible outcomes is the number of cells in the table, which is 16.

Therefore, the probability of two cards chosen not including T is 8/16, which simplifies to 1/2 or 0.5.

Answer: 9/16

Step-by-step explanation:

hopefully (i think)

16 total options

9 don't include a T

so 9/16 don't include T

9/16 also don't include M, so they have equal probabilities, which makes sense since there are an equal number of each letter card

As amended, Sharma’s answer is correct. Other writers (Warda) claimed they could choose any value for x, but the problem states that the altitude (the shorter leg) must be x. First of all that requires that x > 0. Secondly, not every triple of integers (x, 2x+2, 2x+3) is a Pythagorean triple, including x = 11 ((11, 24, 25) is not Pythagorean). As the problem was given, it was not necessary for the solutions to be integers, or even rational numbers, and so, being a Pythagorean triple (of integers) is neither necessary nor sufficient to solve the problem. It is merely the setup of the problem that coincidentally makes it one (the author probably worked backwards to produce integer solutions). I actually was hoping the answer would involve square roots. Or that there be no real solution. An interesting add-on to the problem would be to ask what requirements would there be on the length of the hypotenuse 2x + a that would guarantee a single real solution?

If you spin the spinner 48 times, what is the best prediction possible for the number of times it will not land on yellow?

LOOK AT IMAGE

Answers

Answer:

20 times

Step-by-step explanation:

To determine the best prediction for the number of times the spinner will not land on yellow, we need to calculate the probability of the spinner not landing on yellow in a single spin and then multiply it by the total number of spins.

In this case, there are a total of 12 sectors on the spinner (4 greens + 7 yellows + 1 blue). The probability of the spinner not landing on yellow in a single spin is given by the sum of the probabilities of landing on green or blue:

P(not landing on yellow) = P(green) + P(blue) = 4/12 + 1/12 = 5/12.

Therefore, the probability of the spinner not landing on yellow in a single spin is 5/12.

To predict the number of times it will not land on yellow in 48 spins, we multiply the probability of not landing on yellow by the number of spins:

Prediction = (5/12) * 48 = 20.

Hence, the best prediction for the number of times the spinner will not land on yellow after 48 spins is 20.

It will land 20 times

If you spin the spinner 4 times, what is the best prediction possible for the number of times it will not land on green?

Answer: 2

Step-by-step explanation:

Probability of not green: 1/2

0.5*4=2

Answer:

2 times

Step-by-step explanation:

The spinner is divided into 2 sections one being yellow, one being green. This implies a 1/2 or 50% chance of landing on yellow.

Spinning it 4 times means a 2/4 chance of landing on yellow, which is equal to 1/2. This means that the prediction is that you will land on yellow 2 out of the 4 total times

First, we need to convert the mixed number of hours to an improper fraction:
2 (1)/(2) hours = 2 + 1/2 = (4/2) + 1/2 = 5/2 hours

Next, we calculate the fraction of a picture painted per hour:
Fraction painted per hour = (3)/(4) / (5)/(2) = (3)/(4) * (2)/(5) = (6)/(20) = (3)/(10)

Now, we can calculate the number of pictures painted in 5 hours:
Pictures painted in 5 hours = (3)/(10) * 5 = (15)/(10) = 1.5

The answer is : 1.5 picture

You select a marble without looking and then put it back. If you do this 32,000 times, what is the best prediction possible for the number of times you will pick an orange marble?

LOOK AT THE IMAGE QUICKLYYY

Answers

Answer:

12,000 times

Step-by-step explanation:

The probability of selecting an orange marble in each individual selection is given by:

P(Orange) = Number of orange marbles / Total number of marbles

P(Orange) = 3 / 8 = 0.375

To determine the best prediction for the number of times you will pick an orange marble, we can multiply the probability of selecting an orange marble by the total number of selections:

Best prediction for the number of times you will pick an orange marble = P(Orange) * Total number of selections

Best prediction for the number of times you will pick an orange marble = 0.375 * 32,000

Best prediction for the number of times you will pick an orange marble = 12,000

Therefore, the corrected best prediction possible for the number of times you will pick an orange marble is also 12,000.

the answer is 12,000 times
