Answer:

  1 : 48

Step-by-step explanation:

The scale is ...

  3.5 in : 14 ft = 3.5 in : 168 in = 1 : 48

Answer:

At first we need to convert ft into in

1 ft = 12 in

14 × 12 = 168 inches

Ratio = 3.5 : 168

Ratio = 1:48

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:

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]

Answer:

uh wut's the question?

Step-by-step explanation:

Answer:

There is no question here, what did you need help with?

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.

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:

Step-by-step explanation:

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:

n ≥ 50

Step-by-step explanation:

Total pages = 370

Read pages = 20

Number of days remaining = 7

Reading rate per day = n

7n + 20 ≥ 370

7n ≥ 370 - 20

7n ≥ 350

n ≥ 350/7

n ≥ 50 pages per day for the remaining 7 days

Answer:

1/3y-7

Step-by-step explanation:

For these kinds of problems you want to combine like terms. 2/3y and -1/3y are like terms, and when adding them together, or subtracting 1/3y from 2/3y, you get 1/3y. -3 and -4 are like terms, and adding them together gives you -7. The final expression can be written as 1/3y-7.

To write an equivalent expression, we need to simplify the given expression by combining like terms. Like terms are terms that have the same variable and exponent. We can use the distributive property to remove parentheses or other grouping signs to then combine like terms.

The given expression is -3 + 2/3y - 4 - 1/3y. We can see that there are no parentheses or grouping signs, so we can skip that step. We can also see that there are two like terms: 2/3y and -1/3y. We can combine them by adding their coefficients: 2/3 + (-1/3) = 1/3. So, we get:

-3 + 2/3y - 4 - 1/3y = -3 - 4 + (2/3 - 1/3)y = -7 + (1/3)y

This is the simplified expression that is equivalent to the given expression.

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:

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%.
