Step-by-step explanation:
The given equation is y = 23.67x + 13.12, where y is the value of the stock ABC and x is the number of days. The r-value of 0.9957 indicates a strong positive correlation between the two variables, which suggests that the equation is a good fit for predicting the value of the stock.
To find the value of the stock ABC at x = 28 days, we need to substitute x = 28 into the equation and solve for y:
y = 23.67(28) + 13.12
y = 663.76 + 13.12
y = 676.88
Therefore, the predicted value of the stock ABC at x = 28 days is $676.88.
The closest answer option is D. 675.88, but the correct answer is actually slightly higher at $676.88.
We are given a linear equation y = 23.67x + 13.12, where 'x' is the number of days and 'y' is the stock value.
Now, we need to predict the stock value for 'x' equals to 28 days. To do so, we substitute x = 28 into the equation.
Start by multiplying the given value of x with the slope:
23.67 times 28 equals 662.76.
Next, add the y-intercept to the result from the first step. So you take 662.76 and you add 13.12.
The sum is 675.88.
So, according to our calculation, the ABC stock would be worth 675.88 on the 28th day.
So, the answer is
Answer: D. 675.88.
Enter the trigonometric equation you would use to solve for x in the following right triangle. Do not solve the equation.

Solve for f(5).
f(x) = 2x - 4
f(5) = [?]
Answer & Explanation Included:
f(x)= 2x - 4
f(5)= 2(5) - 4
f(5)= 10 - 4
f(5)= 6
Answer: 16
Step-by-step explanation: f(x) = 2x - 4 means that if we put an x into our function, a 2x - 4 comes out.
So if we want to find f(5), we're putting a 5 into our function which means that a 2(5) - 4 comes out which simplifies to 10 - 4 or 6.
So f(5) = 6 or the value of the function at 5 equals 6.
factorise 4p + 6pq
step by step
answer fully please, thank you.
Answer:
2p(2+3q)
Step-by-step explanation:
Find the Greatest Common Factor (GCF).
GCF = 2p2p
Factor out the GCF. (Write the GCF first. Then, in parentheses, divide each term by the GCF.)
2p(4p/2p + 6qp/2p)
simplify each term in parentheses.
2p(2+3q)
Your answer is 2p(2 + 3q).
First we can start by finding common factors in the coefficients, 4 and 6. 4 and 6 are both divisible by 2, so we can pull this out as our first factor:
2(2p + 3pq)
Now we can look for common factors regarding p and q. Both terms include p, but only one includes q, which means we can also pull the p out as another factor:
2p(2 + 3q)
The expression inside the parentheses cannot be factored anymore, so this is the final factorisation.

6x – 4y = –10
one solution: (–0.6, –1.6)
one solution: (–0.6, 1.6)
no solution
infinite number of solutions
Answer:
one solution: (–0.6, 1.6)Step-by-step explanation:
Given the system of equation,
y = [tex]\frac{2x}{3}+2[/tex]...(1)
6x – 4y = –10 ...(2)
Substituting equation 1 into 2 we have;
6x - 4(2x/3 +2)= -10
6x -8x/3 -8 = -10
Multiplying through by 3;
18x-8x-24=-30
10x=-30+24
10x = -6
Dividing both sides by 10
10x/10 = -6/10
x = -0.6
Substituting x = -0.6 into equation 1 to get the value of y we have;
y = 2(-0.6)/3 + 2
y = -1.2/3 + 2
y = -0.4+2
y = 1.6
This shows that the linear equation has only one solution. The solution is
x = -0.6 and y = 1.6

Each of two urns contains green balls and red balls. Urn I contains 10 green balls and 14 red
balls. Urn II contains 4 green balls and 11 red balls. If a ball is drawn from each urn, what is
P(red and red)?
A.1/9
B.25/39
C.79/60
D.77/180
The probability of drawing a red ball from both urns is found by multiplying the probability of drawing a red ball from Urn I by the probability of drawing a red ball from Urn II. After simplification, the probability is [tex]\(\frac{77}{180}\)[/tex], which corresponds to answer choice D.
To calculate the probability of drawing a red ball from each of two urns, we must first determine the probability of drawing a red ball from Urn I, and then multiply that by the probability of drawing a red ball from Urn II. In Urn I, there are 14 red balls and a total of 24 balls (10 green + 14 red). So, the probability of drawing a red ball from Urn I is [tex]\(\frac{14}{24}\)[/tex].
In Urn II, there are 11 red balls and a total of 15 balls (4 green + 11 red). Hence, the probability of drawing a red ball from Urn II is [tex]\(\frac{11}{15}\)[/tex].
The joint probability of two independent events is the product of their individual probabilities, so to find the probability of drawing a red ball from both urns (P(red and red)), we multiply the two probabilities:
[tex]\(P(red \,\text{from Urn I}) \times P(red \,\text{from Urn II}) = \frac{14}{24} * \frac{11}{15}\)[/tex].
To simplify the calculation:
Simplify [tex]\(\frac{14}{24}\) to \(\frac{7}{12}\)[/tex].Multiply [tex]\(\frac{7}{12}\) by \(\frac{11}{15}\)[/tex].[tex]\(\frac{7}{12} \times \frac{11}{15} = \frac{77}{180}\)[/tex].Therefore, the correct answer is D. 77/180.

Answer:
D
Step-by-step explanation:
I'm sorry, but I don't know what option A is.
However, we are asked which expression has a coefficient greater than one. A coefficient is a number in front of a variable. D is the only one with a coefficient GREATER than 1, so that is the answer.

Answer:
n = y/(r+s)
Step-by-step explanation:
(rn+sn) / y = 1
Multiply each side by y
(rn+sn) / y *y= 1*y
rn+sn = y
Factor out n
n(r+s) = y
Divide each side by (r+s)
n(r+s) / (r+s) = y/(r+s)
n = y/(r+s)
In a clothing store, 75% of the customers buy a shirt, 20% of the customers buy a pair of pants, and 15% of the customers by both the shirt and a pair of pants. If a customer is chosen at random what is the probability that he or she buys a shirt or a pair of pants?
Answer:
80%
Step-by-step explanation:
75% + 20% - 15% = 80%
The probability is 80%
The probability that he or she buys a shirt or a pair of pants is 80%.
What is Probability?Probability helps us to know the chances of an event occurring.
[tex]\rm Probability=\dfrac{Desired\ Outcomes}{Total\ Number\ of\ outcomes\ possible}[/tex]
Given that in a clothing store, 75% of the customers buy a shirt, 20% of the customers buy a pair of pants, and 15% of the customers buy both the shirt and a pair of pants.
The percentage of customers who buy only shirt = 75% - 15% = 60%
The percentage of customers who buy only pant= 20% - 15% = 5%
The percentage of customers who buy both = 15%
Now, the probability that he or she buys a shirt or a pair of pants is,
Probability = 60% + 5% + 15% = 80%
Hence, the probability that he or she buys a shirt or a pair of pants is 80%.

(*It would mean a lot if you could answer*)
Answer:
the hotel is four blocks west from the bus; the bus is four blocks east from the hotel.
The bus is 4 blocks east of the hotel.
Since a sightseeing bus picks up a group of tourists at a hotel, and it then travels 2 blocks north, 2 blocks east, 1 block south, 2 blocks east, and 1 block south, to determine where the bus is in relation to the hotel, the following calculation must be carried out:

Iceberg lettuce is grown and shipped to stores for about 50 cents a head, and consumers purchase it for about 120 cents a head. Find the percent increase.
ANSWER FAST PLEASE
Final answer:
The percent increase in the price of iceberg lettuce is 140%.
Explanation:
To find the percent increase, we need to calculate the difference between the price at which iceberg lettuce is grown and shipped and the price at which consumers purchase it, and then divide that difference by the original price and multiply by 100.
Let's start by finding the difference:
Difference = Consumer price - Production price
Difference = 120 cents - 50 cents = 70 cents
Now, let's calculate the percent increase:
Percent Increase = (Difference / Production price) * 100
Percent Increase = (70 cents / 50 cents) * 100 = 140%

Determine which equation is belongs to the graph of the limacon curve below.
[-5,5] by [-5,5]
We have been given graph of a limacon curve. We are asked to choose the equation that represents the given Limacon.
We can see that our given equation represents a cardiod. The equation of a vertical cardiod is in form [tex]r=a\pm a\cdot \text{sin}(\theta)[/tex] and equation of a horizontal cardiod is [tex]r=a\pm a\cdot \text{cos}(\theta)[/tex].
We can see that our given graph is a vertical cardiod, so its equation will be in form [tex]r=a\pm a\cdot \text{sin}(\theta)[/tex] .
The positive sign gives an upside-down cardiod and negative sign orients the cardiod upright.
Since our given graph is upright, so we will have a negative sign between 'a'.
Therefore, the equation [tex]r=2-2\cdot \text{sin}(\theta)[/tex] represents the given graph and option 'd' is the correct choice.

If angle B measures 120 degrees, find
the Q
A.30 degrees
B.60 degrees
C.120 degrees
D.90degrees
Answer:
C. 120°
Step-by-step explanation:
There are two paralell lines, one is part of Angle B, and the other of Angle Q. Then there is a diagonal line, coming at the same angle from B all the way to Q, because the other two lines are paralell. It basically means if you were to slide the flat line which is connected to Q up the diagonal line, it would fit perfectly with it's parallel. So the two angles; Angle B and Angle Q; are the exact same.

The statue of Liberty stands on a 150 ft. pedestal. From a point 250 ft. from the base of the
pedestal, the angle of elevation to the top of Liberty's torch is 50°. Find the height of the Statue
of Liberty
how do i do it?
Answer:
148ft
Step-by-step explanation:
To solve this question, you'll have to imagine the statue makes a right angle triangle with the base since it has an angle of elevation from the base to the top of the torch.
Assuming the height from the pedestal to the top of the torch is y
The height of the statue is x
But we know the height of the pedestal = 150ft
The distance from the observer to the base of the pedestal = 250ft
And the angle of elevation = 50°
See attached document for better illustration.
Tanθ = opposite / adjacent
θ = 50°
Adjacent = 250
Opposite = y
Tan50 = t / 250
y = 50 × tan50
y = 50 × tan50
y = 50 × 1.1917
y = 297.925ft
The height of the statue from the base of the pedestal to the top of the torch is 297.925ft
The height of the statue = x
x = (height of the statue + height of the pedestal) - height of the pedestal
x = y - 150
x = 297.925 - 150
x = 147.925ft
Approximately 148ft
The height of the statue is 148ft
