At the Hula Factory, the assembly line produces 212 leis in a batch. The leis are packaged in boxes with 30 each. If 14 batches are made in one day, how many leis will be leftover at the end of it?

Therefore , the solution of the given problem of ratio comes out to be

CD:DE = 1:2. and AB:BC = 2:1 .

Use the simple formula "a / b" to create a group of linked variables "a" and "b," where "b" may also be higher than zero. One ratio is created by combining two equation ratios. If there were only one man and three ladies, the ratio would be 1:1. There are 1/4 males and 3/4 girls in the group. A division between two or more objects, a number, or even a portion of a component's volume are all examples of parts.

Here,

Ratio 1: AB:BC = 2:1

Let's use the midpoint formula to find the coordinates of point C, which is the midpoint of line segment AB:

C = ((5+x)/2, (0+y)/2) = ((5+x)/2, y/2)

Since AB:BC = 2:1, we know that the distance from A to B is twice the distance from B to C. Using the distance formula, we can write:

2 * BC = AB

2 * √((x+1)² + y²) = √((x-5)^2 + y^2)

Simplifying this equation, we get:

4 * (x+1)² + 4y² = x² - 10x + 25 + y²

Simplifying further, we get:

3x²+ 8x - 16y² - 75 = 0

Ratio 2: CD:DE = 1:2

Let's use the midpoint formula to find the coordinates of point E, which is the midpoint of line segment CD:

E = ((p-1)/2, (q-4)/2)

Since CD:DE = 1:2.

Therefore , the solution of the given problem of ratio comes out to be

CD:DE = 1:2. and AB:BC = 2:1 .

Answer:

526.68

To find out how much the price went up, you first want to find what 32% of 399 is.

32% of 399 = 127.68

The price will go up $127.68.

Now, just add that to the original price:

127.68 + 399 = 526.68

The price of the game system will now be $526.68

A. X is a discrete random variable

B. The conditions are satisfied.

C. The expected value of X is 15.25

A. X is a discrete random variable because it can only take on specific values (0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16) and not any value in an interval.

B. To show that the probability distribution is valid, we need to check if the following conditions are satisfied:

1. P(X=x) ≥ 0 for all x in the set of possible values of X

2. The sum of all probabilities equals 1

From the information given, it appears that these conditions are satisfied.

C. The expected value of X can be calculated as the weighted average of all possible values of X, where the weights are their corresponding probabilities.

E(X) = Σ[x * P(X=x)]

E(X) = (14*0.15) + (15*0.55) + (16*0.20) + (17*0.10) = 15.25

The expected value of X, which is 15.25, represents the mean or average number of credits taken by a randomly selected first-year student at the large state university.

D. The standard deviation measures the amount of variation or dispersion of a set of data values. A low standard deviation indicates that the values are close to the mean (expected value), while a high standard deviation indicates that the values are spread out over a wider range. In this context, a standard deviation of 0.829 means that the number of credits taken by first-year students at the university is spread out over a range of approximately 0.829 units on average.

E. The event "taking at least 16 credits" can be expressed as X ≥ 16. To find its probability, we can sum up the probabilities of all the values that are greater than or equal to 16.

P(X ≥ 16) = ΣP(X = x)

P(X ≥ 16) = 0.20 + 0.10 = 0.30

Answer: $252 for 120 ft

Step-by-step explanation: Divide the money by the feet value in order to find dollars per foot. Since 252/120 = 2.1 $/ft and 285/150 = 1.9 $/ft, it would be better value to go with the 1.9 $/ft option.

The value of k that makes the probability distribution valid is given as follows:

k = 4.

To obtain the value of k, we must consider that the integral assumes a value of 1 over it's entire domain, that is:

[tex]\int_{-1}^{1} F(x) dx = 1[/tex]

The function F(x) is given as follows:

F(x) = (x + 2)/k.

Considering 1/k as a constant, the integral is given as follows:

1/k[0.5x² + 2x].

At x = 1, the integral is given as follows:

0.5 + 2 = 2.5.

At x = -1, the integral is given as follows:

0.5 - 2 = -1.5.

Applying the Fundamental Theorem of Calculus, the result of the integral is given as follows:

1/k[2.5 - (-1.5)] = 4/k.

As the result of the integral must be of one, the value of k is obtained as follows:

4/k = 1

k = 4.

The cost of printing x business cards can be represented by the linear function C(x) = 0.05x + 20.  The cost of printing 950 business cards is $67.50.

The cost of printing business cards is a linear function, C(x) = mx + b, where C(x) is the cost of printing x business cards, m is the rate at which the cost increases as the number of cards increases, and b is the constant term or the cost of printing zero business cards. In this case, m = 0.05 and b = 20.

The equation C(x) = 0.05x + 20 represents the cost of printing x business cards, where x is the number of cards printed. The term 0.05x represents the cost of printing x cards at a rate of $0.05 per card, and the term 20 represents a fixed cost of $20, regardless of the number of cards printed.

To find the cost of printing 950 business cards, we simply substitute x = 950 into the equation:

C(950) = 0.05 * 950 + 20

C(950) = 47.5 + 20

Z = 2P - 4  ---- (2)

N + P + Z = 94  ---- (3)

Put (1) and (2) in (3):

P+2 + P + 2P-4 = 94

4P -2 = 94

4P = 94 + 2

The value has now surpassed $10,000, the car was worth more than $10,000 from year 3 until year 2, or 1 year.

Rounding to the nearest hundredth, the interval is 1 year.

Using the following formula, we can determine the car's value each year:

value = 20000 * [tex](1 - 0.15)^year[/tex]

We're looking for the years where the value exceeds $10,000.

Let's start by determining the car's value after 1 year:

value = 20000 * [tex](1 - 0.15)^1[/tex] = 20000 * 0.85 = 17000

We need to keep lowering the value since it will eventually exceed $10,000 because the value after one year is less than $10,000.

After 2 years:

value = 20000 * (1 - 0.15)² = 20000 * 0.85² = 14525

Still less than $10,000.

After 3 years:

value = 20000 * (1 - 0.15)³ = 20000 * 0.85³ = 12318.75

Since the value has now surpassed $10,000, the car was worth more than $10,000 from year 3 until year 2, or 1 year.

For which the parameters are given as follows:

The function has a maximum value of 6 and a minimum value of 0, for a difference of 6 units, hence the amplitude is obtained as follows:

2A = 6

A = 3.

Without vertical shift, a function with amplitude of 3 would oscillate between -3 and 3, while this one oscillates between 0 and 6, hence the vertical shift is given as follows:

[tex]w = \frac{75(\sqrt{2} - 5)}{(\sqrt{2} + 5)(\sqrt{2} - 5)}[/tex]

Step-by-step explanation:

The equation of the line in slope-intercept form is given by y = mx + b, where m is the slope and b is the y-intercept.

With a slope of -2.5 and a point (2,1.5) on the line, we can use the point-slope formula to find the equation of the line:

y - 1.5 = -2.5 (x - 2)

Expanding the right-hand side, we get:

y - 1.5 = -2.5x + 5

Adding 1.5 to both sides, we get:

y = -2.5x + 6.5

So the equation of the line in slope-intercept form is y = -2.5x + 6.5.
