Remark

What a wonderful problem. I've never seen one quite like it.

Red to Yellow

The Red to Yellow ratio is given as 3:5

The total number of Red and yellow is something to 8. You get that just by adding the ratio. Let's check it out.

The reds are 3 to 8 and the yellows are 5 to 8.

Does that make sense? 3/8 + 5/8 = 8/8. All the cubes are accounted for.

Small to Large

The given ratio is 4:9

The smalls are 3/13 and the large are 9/13

3/13 + 9/13 equal 13/13 and all the cubes are accounted for.

What is the least possible number that will accomplish this?

8 * 13 is the very least number that will accomplish this. How come?

Because you have two conditions that must be met -- size and color. No other number will work.  Any other number will leave a remainder when you put color and size together. So the smallest number you can use is 104,

Last question: Least Number of Large Yellows

The color yellow is 5/8

The size is Large 9/13

So the calculation is

5/8 * 9 / 13 * 104

= 5 * 9

= 45

Notice that the 8 and 13 cancel out. You are left with the number of Yellows and Large =45

Note

I'll leave the other 3 combinations to you. They should add up to 104.

3/8 * 9/13 * 104 = 27

5/8 * 4/13 * 104 = 20

3/8 * 4/13 * 104 = 12

Answer:

35%

Step-by-step explanation:

The percent error can be found using the

|Experimental value - Theoretical value| divided by |Theoretical value| and multiplied by 100.

I hope this helps

Here, the experimental probability is 1/4 and theoretical probability is 1/18.Then the percent difference between the theoretical probability and the experimental probability is 56%.

The probability is a measure of chances that an event to take place.

Given that,

red marbles = 3

blue marbles =1

yellow marbles = 2

Then.

theoretical probability of selecting a blue marble followed by a yellow marble is:

P(blue and yellow) = P(blue) x P(yellow) = (1/6) x (2/6) = 1/18

Since the marbles are replaced after each draw, the probability of this event is the same for every draw.

The experimental probability of selecting a blue marble followed by a yellow marble after 40 attempts is:

(3/6) x (2/6) x (40 attempts) = 10

Therefore, the experimental probability is 10/40 = 1/4

The percent difference between the theoretical probability and the experimental probability is:

| (experimental probability - theoretical probability) / theoretical probability | x 100%

= | (1/4 - 1/18) / (1/18) | x 100%

= 0.583 x 100%

= 58.3%

Therefore, the percent difference between the theoretical probability and the experimental probability is approximately 58.3%, which is closest to the option 56%.

Answer:

Step-by-step explanation:

The angle is between 3pi/2 and 2pi so it is in the fourth quadrant where both sin and tan are negative.

Given cos(θ) = sqrt(2)/2

cos^2(θ) + sin^2(θ) = 1

sine^2(θ) = 1 - 2/2^2 = 1 - 1/2 = 1/2

sin(θ) = +/1 sqrt(2)/2

As we know sin(θ) is negative,

sin(θ) =  -sqrt(2)/2; the second answer

tan(θ) = sin(θ)/cos(θ) = -1

Answer:

Step-by-step explanation:

using (cosθ)^2 + (sinθ)^2 = 1

2/4 + (sinθ)^2 = 1

sinθ = [tex]\sqrt{2}/2[/tex]

or -[tex]\sqrt{2} /2[/tex]

By C-A-S-T, sinθ is -ve

sinθ = -[tex]\sqrt{2}/2[/tex]

tanθ = sinθ/cosθ = -1

Answer:

You would receive $13.75

Step-by-step explanation: What i did was divided 7.50 by 6 so it would give me the price of 1 bagel(1.25).I subtracted 11 and 6 which would give me 5 so I know how much I need to calculate with the discount. Then I multiplyed 5 times 1.25 (6.25) so I could get the price for 5 bagels. After I added 7.50 and 6.25 which would give you your answer of $13.75.

answer:10×2=20

5×3=15

Answer:

y = 7.5

Step-by-step explanation:

Given y varies directly with x then the equation relating them is

y = kx ← k is the constant of variation

To find k use the condition y = 10 when x = 20

10 = 20k ( divide both sides by 20 )

[tex]\frac{1}{2}[/tex] = k

y = [tex]\frac{1}{2}[/tex] x ← equation of variation

When x = 15 , then

y = [tex]\frac{1}{2}[/tex] × 15 = [tex]\frac{15}{2}[/tex] = 7.5

Answer:

the initial investment is $1,200

Step-by-step explanation:

The computation of the initial investment is shown below:

As we know that

Let us assume the investment be 100

So, the investment increased be 72

So,

Simple interest = Principal × rate of interest × time period

72 = Principal × 3% × 2 years

So, the principal is

= 72 ÷ 3% × 2

= $1,200

hence, the initial investment is $1,200

Answer:

The numerator of this fraction is b^(-11).  The -11 is the sum of -4 and -7.  

The denominator is b^(-5).

Recall that b^a / b^c = b^(a - c).  Thus, b^(-11) / b^(-5) = b^(-6)

Answer:

The grade you receive on a test is a discrete random variable with probability mass function

[tex]f_X(x)=P(X=x)=\begin{cases}0.4&\text{for }X=4\text{ (i.e. scoring an A)}\\0.2&\text{for }X=3\text{ (B)}\\0.15&\text{for }X=2\text{ (C)}\\0.25&\text{for }X=1\text{ (D)}\\0&\text{otherwise}\end{cases}[/tex]

where the probability of getting a D is 25% because there are only 4 possible grades, and the probabilities must sum to 1 :

0.4 + 0.2 + 0.15 + 0.25 = 1

The expected test score/GPA is then

[tex]\displaystyle\sum_x x\,f_X(x)=\sum_{x=1}^4 x\,P(X=x)=1\cdot0.25+2\cdot0.15+3\cdot0.2+4\cdot0.4=\boxed{2.75}[/tex]

so your average would fall between a B and a C.
