You select a marble without looking and then put it back. If you do this 45 times, what is the best prediction possible for the number of times you will pick a purple marble?
NO WRONG ANSWERS PLEASEE
Answer:
9 times
Step-by-step explanation:
If there are 4 pink marbles and 1 purple marble, the probability of picking the purple marble on any individual trial is 1/5 (since there is one purple marble out of a total of five marbles).
Therefore, the best prediction for the number of times you will pick a purple marble in 45 trials would be:
E = (1/5) × 45 = 9
So, the best prediction is that you will pick a purple marble approximately 9 times out of the 45 trials.
Answer:9
Step-by-step explanation:
(1/5)*45=9

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.

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?

Answer:
bottom right graph
Step-by-step explanation:
Line of best fit is a line that is created on a graph with a bunch of points. This line must fall somewhat close to a majority of the points, or else it wouldn't be of "best fit".
The top left graph has the line maybe going through 2-3 points.
The top right graph has the line going through 0 points.
The bottom left graph goes through none.
So the answer is bottom right.
Hope this helps! :)

You select a marble without looking and then put it back. If you do this 48 times, what is the best prediction possible for the number of times you will pick a green or an orange marble?
LOOK AT THE IMAGE
Step-by-step explanation:
the correcto anwar
es pero que te cirba
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.

An artist’s canvas has sides measuring 3x – 3 and 4x + 1 inches.
What is the area of the canvas? Show all work.
The artist laid the canvas flat on the floor and poured some paint in the center. The paint flows at a rate of r(t) = 4t where t represents time in minutes and r represents how far the paint is spreading on the canvas. The area of the paint can be expressed as A[r(t)]= πr². What is the area of the circle created by the paint?
If the artist wants the circle to be at least 1300 in², will it be that large in 5 minutes? Support your answer with your work.
Step-by-step explanation:
Finding the area of the canvas:
The canvas has sides measuring 3x - 3 and 4x + 1 inches. To find the area, we multiply the lengths of the sides. So, the area of the canvas is given by:
Area = (3x - 3) * (4x + 1)
= 12x^2 + x - 3
Therefore, the correct equation for the area of the canvas is A = 12x^2 + x - 3.
Finding the area of the circle created by the paint:
The rate at which the paint is spreading on the canvas is given by the function r(t) = 4t, where t represents time in minutes and r represents how far the paint has spread. The area of the circle created by the paint can be expressed as A[r(t)] = πr^2, where r(t) is the distance the paint has spread at time t.
Substituting the value of r(t) = 4t into the formula, we get:
A[r(t)] = π(4t)^2
= 16πt^2
Therefore, the area of the circle created by the paint is 16πt^2.
Determining if the circle will be at least 1300 in² in 5 minutes:
To check if the area of the circle will be at least 1300 in² in 5 minutes, we substitute t = 5 into the equation for the area:
A[r(5)] = 16π(5)^2
= 400π
Approximating the value of 400π, we get approximately, 1256.64.
Since 1256.64 is less than 1300, we can conclude that the area of the circle created by the paint after 5 minutes will not be at least 1300 in².

Step-by-step explanation:
The base number (7) is the same, so we can just add the exponents together.
Hope that helped!
To write 7^3 x 7^2 using a singular exponent, you can add the exponents together since the bases (7) are the same. The result is:

You select a marble without looking and then put it back. If you do this 60 times, what is the best prediction possible for the number of times you will pick a blue or a purple marble?
LOOK AT IMAGEEE
Based on the given information, where there are 7 blue marbles and 3 purple marbles, and assuming the selection process is random and each marble has an equal chance of being selected, the best prediction for the number of times you will pick a blue or a purple marble can be calculated as follows:
Out of the 60 selections, we can expect to pick a blue marble approximately 7/10 times (since there are 7 blue marbles out of a total of 10 marbles). Therefore, the best prediction for the number of times you will pick a blue marble is around 60 * (7/10) = 42 times.
Similarly, we can expect to pick a purple marble approximately 3/10 times (since there are 3 purple marbles out of a total of 10 marbles). Therefore, the best prediction for the number of times you will pick a purple marble is around 60 * (3/10) = 18 times.
Hence, the best prediction is that you will pick a blue marble around 42 times and a purple marble around 18 times out of the 60 selections.
~~~Harsha~~~
Answer:
18 times
Step-by-step explanation:
If there are 7 blue marbles and 3 purple marbles, the probability of selecting a blue marble is 7/10, and the probability of selecting a purple marble is 3/10.
Since you're selecting marbles without replacement, the probability will change with each pick. To calculate the best prediction for the number of times you will pick a blue or purple marble, we can multiply the probabilities by the number of picks.
Expected number of blue marbles picked: (7/10) * 60 = 42
Expected number of purple marbles picked: (3/10) * 60 = 18
Therefore, the best prediction is that you will pick a blue marble approximately 42 times and a purple marble approximately 18 times when selecting marbles without looking 60 times.

Answer:
C. $87.00
Step-by-step explanation:
If all shoes at Pearl's Vintage Wear are 25% off, then the sale price of a pair of shoes that originally cost $116 would be:
$116 - (25% x $116) = $87
Therefore, the sale price would be $87. The answer is C.
