To increase the probability from 1/5 to 1/4, we need to remove 24 blue marbles from the bag.
Explanation:To increase the probability from 1/5 to 1/4, we need to find the number of blue marbles that need to be removed. Let's assume there are x blue marbles in the bag. Initially, the total number of marbles in the bag is 30, and the probability of picking a red marble is 1/5. This means that (30 - x)/30 = 1/5. Solving this equation, we get x = 24. Therefore, 24 blue marbles need to be removed from the bag to increase the probability to 1/4.

Because the initial probability of picking a red marble from 30 marbles is 1/5, there are 6 red marbles in the bag. If we want to increase the probability of drawing a red marble to be 1/4, we need to reduce the total number of marbles in the bag to 24. So, we must remove 6 non-red marbles, which could be blue.
Explanation:The subject of your question is probability in Mathematics. Initially, we have 30 marbles, and the probability of picking a red one is 1/5. So, there are 1/5 * 30 = 6 red marbles in the bag. Thus, the bag also contains 24 non-red marbles, which can be blue or other colors.
Next, we want the probability of picking a red marble to be 1/4. Since the number of red marbles will remain the same, we need to change the total number of marbles in the bag. If 'x' is the number of marbles in the bag, then 6/x = 1/4, which means x = 24. Since initially we had 30, to get to 24 we need to remove 6 marbles.
Therefore, if we remove 6 blue marbles (or any non-red marbles), the probability of picking a red marble will increase to 1/4.

Suppose the Willard gold nugget was turned into 4 equal sized gold bricks. If one of the bricks was sold how many ounces of the Willard nugget would be left?
The number of ounces left after one brick is sold is 591.
What is an expression?An expression is a way of writing a statement with more than two variables or numbers with operations such as addition, subtraction, multiplication, and division.
Example: 2 + 3x + 4y = 7 is an expression.
We have,
Willard gold nuggets = 788 ounces
The number of equal-sized bricks = 4
Now,
The number of ounces in each of the 4 bricks.
= 788/4
= 197 ounces
Number of bricks sold = 1
The remaining ounces.
= 788 - 197
= 591 ounces
Thus,
The number of ounces left is 591.

On a flight New York to London an airplane travels at a constant speed. An equation relating the distance traveled in miles d to the number of hours flying t is t= 1/500d. How long will it take the airplane to travel 800 miles?
Answer:
1.6 hours or 1 hour 36 minutes
Step-by-step explanation:
We have been given an equation [tex]t=\frac{1}{500}d[/tex], where d represents distance traveled in miles and t represents time in hours.
To find the time taken by the flight to travel 800 miles, we will substitute [tex]d=800[/tex] in our given equation as:
[tex]t=\frac{1}{500}\times 800[/tex]
[tex]t=\frac{800}{500}[/tex]
[tex]t=\frac{8}{5}[/tex]
[tex]t=1.6[/tex]
1 hour equals 60 minutes.
0.6 hours = 0.6*60 minutes = 36 minutes.
Therefore, it will take the plane 1.6 hours or 1 hour 36 minutes to travel 800 miles.
Using the equation, it is found that it will take 1.6 hours for the airplane to travel 800 miles.
The equation that relates the time in hours needed to travel d miles is given by:
[tex]t = \frac{1}{500}d[/tex]
In this problem, we want the time needed to travel 800 miles, thus [tex]d = 800[/tex], and:
[tex]t = \frac{1}{500}(800) = \frac{800}{500} = 1.6[/tex]
It will take 1.6 hours for the airplane to travel 800 miles.

Write an equation and solve. Round to the nearest hundredth where necessary. What is 35% of 63?
n = 35 • 0.63; 22.05
n = 0.35 • 63; 22.05
n = 35 • 63; 2,205
n • 0.35 = 63; 180
Answer:
n = 0.35 • 63 = 22.05Step-by-step explanation:
To find the 35% of 63, we first should transform the percentage in a fraction, and then operate.
SO, we know that
[tex]35\%=\frac{35}{100}[/tex]
Multiplying this with 63, we have:
[tex]n=\frac{35}{100}63=0.35(63)=22.05[/tex]
Therefore the right answer is the second choice.

Jones middle school has 850 students and gets 5 new students per month. Roberts Middle School has 985 students and 10 students withdrawal each month. After how many months will Jones Middle School have students than Roberts Middle School
Jones Middle School will have more students than Roberts Middle School after 9 months.
Explanation:To find out after how many months Jones Middle School will have more students than Roberts Middle School, we need to determine the point at which the number of students at Jones Middle School exceeds the number of students at Roberts Middle School. Let's calculate the number of months it takes for this to happen:
Number of students at Jones Middle School = 850 + 5n (n represents the number of months)
Number of students at Roberts Middle School = 985 - 10n (n represents the number of months)
We need to find the value of n when the number of students at Jones Middle School is greater than the number of students at Roberts Middle School:
850 + 5n > 985 - 10n
Simplifying the inequality:
15n > 135
n > 9
Therefore, after 9 months, Jones Middle School will have more students than Roberts Middle School.
