Change the red fraction so both fractions will have the same denominator

2/3 change to 14/21

Add blue and red together

14/21 + 4/21 = 18/21

Then subtract it from the total to get the white beads

21/21 - 18/21 = 3/21

Simplify it to get 1/7

Ans : 1/7

Fraction of white beads used is 1/7.

A number expressed as a quotient, in which a numerator is divided by a denominator.

Given:

red beads used = 2/3 = /1

The height of the drop is 295 feet.

Answer:

295 hope this helps!!

Step-by-step explanation:

For this system of equation I used substitution:

Step 1: Every time you see a y in the equation y = 2x - 1 replace it with -4x - 19

-4x - 19 = 2x - 1

Step 2: Isolate x

(-4x + 4x) - 19 = (2x + 4x) - 1

-19 = 6x - 1

-19 + 1 = 6x + (- 1 + 1)

-18 = 6x

x = -3

Step 3: To solve for y replace x in the equation y = 2x - 1 with -3

y = 2(-3) - 1

y = -6 - 1

y = -7

(-3, -7)

Check:

-7 = -4(-3) - 19

-7 = 12 - 19

-7 = -7 --------------------------------> Correct!

-7 = 2(-3) - 1

-7 = -6 - 1

-7 = -7 --------------------------------> Correct!

Find the attached

Step-by-step explanation:

We are given the following linear equation;

-3y = 2x - 7

In order to graph it, we need to determine at least 3 pairs of points that lie on the line;

we first solve for y by dividing both sides of the equation by -3;

y = (-2/3)x + 7/3

let x be 3;

y = (-2/3)*3 + 7/3

y = 1/3

(3, 1/3)

let x be 6;

y = (-2/3)*6 + 7/3

y = -5/3

(6, -5/3)

let x be 9;

y = (-2/3)*9 + 7/3

y = -11/3

The probability that we will get a lead role, given that we are chosen to be in the play is 0.5.

Probability is the ratio that shows the likelihood of an event occurring from a given set of possible events.

The probability that we will be chosen for the play is 0.4.

The probability that we will get the lead role is 0.1.

We have to find the probability that we get a lead role, given that we are already chosen to be in the play.

In this situation, the probability can be found by adding the probability of being chosen and the probability that we will get the lead role.

This can be done as shown below:

The probability that we get a lead role, given that we are already chosen to be in the play = The probability that we will be chosen for the play + The probability that we will get the lead role

= 0.4 + 0.1

= 0.5

The probability of us getting a lead role given that we have already been chosen for the play is found to be 0.5. The correct answer is option D.

The amount of Thorium-228 left after 22.8 years of decay from an initial 50 gram sample, given its half-life of 1.9 years, is 0.124 grams.

In this problem of thorium -228 decay, we apply the formula for exponential decay which is A=A0e^-kt. 'A0' represents the initial amount, which in this case is 50 grams. 'A' is the final amount after 't' years, and 'k' is the decay constant. To find the decay constant first, we note that thorium-228 decays to 50% of its initial quantity in 1.9 years. Therefore, we can write the equation 0.5=A0e^-1.9k. Solving for 'k', we get k = ln(2)/1.9, which allows us to derive the time constant for the decay.

Now we use this value of 'k' to find out the amount of thorium-228 left after 22.8 years. Plugging the values into our formula, we get: A = 50e^((ln2/1.9)*-22.8). Solving this yields a value of 0.124 grams, which means option C is correct.

To find the amount of thorium-228 remaining after 22.8 years, we can use the formula A = A0e -kt. The correct answer is B) 30.32 grams.

To solve this problem, we can use the formula A = A0e-kt where A is the amount of the substance at a given time, A0 is the initial amount, k is the decay constant, and t is the time elapsed.

In this case, we are given that thorium-228 decays 50% every 1.9 years.

This means that the decay constant k = ln(2)/1.9. We can substitute the values into the formula and solve for A: A = 50 * e(-ln(2)/1.9)*22.8 = 30.32 grams.

Therefore, the correct answer is B) 30.32 grams.

Answer:

8 laps

Step-by-step explanation:

Assuming in the equation given than n represents the number of laps run and t represents the time in minutes, when we plug in 16 in for t and simplify we get:

n=5/10*16

n=1/2*16 (Simplify the fraction by dividing top and bottom by 5)

n=16/2 (Multiply the fractions together by writing 16 as 16/1 and multiplying straight across)

n=8

Answer:

8

Step-by-step explanation:

This question is a bit of a guess. You have to assume that n is in laps and that t  is in minutes.

n = (5/10) * t Reduce 5/10 to 1/2

n = 1/2 * 16

n = 8

So if the assumptions are correct, he should be able to do 8 laps.

Step-by-step explanation:

(x-10)+(x-5)+(x)=3x-15

3x - 15

Simply add the different container sizes together. The first container holds x - 10 liters, the second holds x - 5 liters, and the third holds x liters.

(x - 10) + (x - 5) + x

Because of the associative property of Addition, we can remove the parentheses.

x - 10 + x - 5 + x

Because of the communicative property of addition, we can reorder the terms so that the like terms are next to each other.

x + x + x - 10 - 5

Now, combine the x’s.

3x - 10 - 5

Finally, subtract -10 minus - 5.

The answers are already in order, so it makes this more simple to solve. To find the mean of all those numbers, you must add all the numbers up, then divide by the numbers that is given. In which this problem, it gives 6 numbers. 

So, 1+35+36+37+37+38= 184. Then, divide it 184/6= 30.6. The mode is the number that occurs the most in that set of numbers. In this case, it would be 37. The median is basically the number in the middle when the set of numbers is ordered from least to greatest. 1,35,36,37,37,38 (here's a hint: cross it off on each side) If there is no obvious middle number, in this case because we have an even set of numbers, we can calculate the median by taking the mean of the 2 middlemost terms and: 36, 37. 

36+37= 73

After that, divide by 2. 

73/2= 36.5

Answer:

Mean=30[tex]\frac{2}{3}[/tex]    Median= 36.5     Mode= 37

i) P(A) ; The probability that event A occurs

ii) P(AB) ; The probability that both event A  and event B occur

iii) P(AUB) ; The probability that either event A  or event B occurs

iv) 1 - P(ANB) ; The probability that both events A  and B do not occur                                 together, but either  may occur by itself

v) 1- P(AUB) ; The probability that neither event A  or event B occurs

vi) P(AIB) ; The probability that event A occurs  given the fact that event B occurs

Step-by-step explanation:

i)

P(A) simply represents the probability that an event A will occur. This event could be passing an examination, having snow in summer, arriving to work on time and so forth.

ii)

P(AB) is simply the probability that both event A  and event B do occur. This is usually given by the product of the individual probabilities. Event A could be rolling a 6 in one throw of a fair die while B could be the event that a fair coin lands heads in a single toss.

iii)

P(AUB) refers to the probability that either event A  or event B occurs. This is read out as the probability of A union B. This is usually given by the sum of the individual probabilities.

iv)

1 - P(ANB) is the probability that both events A  and B do not occur                                 together, but either  may occur by itself. P(ANB) is the probability that both events A  and B occur together. This is read out as the probability of A intersection B. Therefore implying that 1 - P(ANB) is simply the probability that either event A or B occurs but A and B can not occur together.

v)

1- P(AUB) refers to the probability that neither event A  or event B occurs. Earlier we defined P(AUB) as the probability that either event A  or event B occurs. 1- P(AUB) simply the complement of P(AUB).

vi)

P(AIB) refers to the probability that event A occurs  given the fact that event B occurs. This is a conditional probability event which evaluates the likelihood of an event A occurring given that an associated event B has already occurred
