There were 680 gallons of water ALREADY in a 1600-gallon pool. Water is being pumped into the pool at the rate of 320 gallons per hour. Let x represents the number of hours. Find how many hours it will take to fill the pool.
Answers
Answer:
2 7/8 hours
Step-by-step explanation:
Answer:
2hrs 12 mins
Step-by-step explanation:
5hrs = 5x = 1600 question asks us to find 680
2 1/2x + 680-640 =-x + 2.8hrs
2x + 40 = x + 2.8hrs
2x + 40 = 680
Then use the 2.8 to convert into hrs : minutes ie) 0.8 x 60
0.8 * 60 = 48 minutes
Then go back to x + 2.8hrs = x + 2hrs 48mins
2x + 48 = 60
2x + 48 = 60
2x+ 60 - 48
x = 2:12 hours
suppose that rosa's favorite is sausage and onion, but her mom can't remember that, and she is going to randomly choose 222 different toppings. what is the probability that rosa's mom chooses sausage and onion?
Answers
The probability of choosing sausage and onion by Rosa's mom from the given 8 different toppings as per given condition is equal to
(1/ ⁸C₂).
As given in the question,
Total number of different toppings = 8
Number of different toppings choose by Rosa's mom randomly = 2
Possibility of choosing sausage and onion (any one) = 1
Total number of outcomes = ⁸C₂
Number of favorable outcomes = 1
Probability of choosing sausage and onion ( exactly ) one topping
= ( Number of favorable outcomes ) / ( Total number of outcomes )
= ( 1/⁸C₂ )
Therefore, the probability when Rosa's mom chooses sausage and onion out of 8 toppings is equal to ( 1/⁸C₂ ).

Answers
The 95% confidence interval for a person's weight gain, measured in pounds, is approximately -6.22 to 25.60 pounds.
To determine the 95% confidence interval for weight gain, we can use the given equation: Whighi = (-94.4395) + (3.7430 × 140.ghtR). Here, Whighi represents weight gain in pounds and 140.ghtR represents the weight measured in lehes.
First, let's calculate the standard error (SE) using the formula: SE = √[(2.0425)² × (0.2945)²]. Plugging in the values, we get SE ≈ 0.609.
Next, we can calculate the margin of error (ME) by multiplying the SE with the critical value corresponding to a 95% confidence level. As the equation provided does not explicitly state the critical value, we'll assume it to be 1.96, which is commonly used for a 95% confidence level. Therefore, ME ≈ 1.96 × 0.609 ≈ 1.196.
Now, we can construct the confidence interval by adding and subtracting the ME from the mean weight gain. The mean weight gain can be found by substituting the given weight measurement of 140.ghtR into the equation Whighi = (-94.4395) + (3.7430 × 140.ghtR). Calculating the mean weight gain, we get ≈ 25.60 pounds.
Thus, the 95% confidence interval for a person's weight gain is approximately -6.22 to 25.60 pounds. This means we are 95% confident that the true weight gain for a person lies within this interval.

Answers
Answer:
2/16
Step-by-step explanation:
First you need to find a common multiple of 4 and 8. Let's do sixteen.
Since we have changed the denominator, we need to change the numerator aswell
3/4 turns to 12/16 because to get sixteen, 4 is multiple by four, so we do the same to the 3 (multiply it by 4)
5/8 turns in 10/16, because we multiplied the 8 (denominator) by 2, so we have to do the same to the 5 (numerator).
12/16-10/16=2/16,
you can also simplify it to 1/8, if you want.
The distribution of results from a cholesterol test has a mean of 180 and a standard deviation of 20. A sample size of 40 is drawn randomly. Find the probability that the sum of the 40 values is less than 7,100. (Round your answer to four decimal places.)
Answers
Using the normal distribution, there is a 0.2148 = 21.48% probability that the sum of the 40 values is less than 7,100.
Normal Probability DistributionThe z-score of a measure X of a normally distributed variable with mean \(\mu\) and standard deviation \(\sigma\) is given by:
\(Z = \frac{X - \mu}{\sigma}\)
The z-score measures how many standard deviations the measure is above or below the mean. Looking at the z-score table, the p-value associated with this z-score is found, which is the percentile of X.By the Central Limit Theorem, the sampling distribution of sample means of size n has standard deviation \(s = \frac{\sigma}{\sqrt{n}}\).For this problem, these parameters are given as follows:
\(\mu = 180, \sigma = 20, n = 40, s = \frac{20}{\sqrt{40}} = 3.1623\)
A sum of 7100 is equivalent to a sample mean of 7100/40 = 177.5, which means that the probability is the p-value of Z when X = 177.5, hence:
\(Z = \frac{X - \mu}{\sigma}\)
By the Central Limit Theorem:
\(Z = \frac{X - \mu}{s}\)
\(Z = \frac{177.5 - 180}{3.1623}\)
Z = -0.79
Z = -0.79 has a p-value of 0.2148.
There is a 0.2148 = 21.48% probability that the sum of the 40 values is less than 7,100.

Y is inversely proportional to the cube of x when x=1/2,y=24 find the formula for y in terms of x
Answers
The formula for y in terms of x is y = 3/x³.
Inversely Proportional:
When two variables are inversely proportional to each other, then the value of one quantity increases with respect to decrease in other or vice-versa.
So, it can be written as,
y = k/x
where,
y is inversely proportional to x and k is the constant of proportionality.
Given,
Y is inversely proportional to the cube of x.
Here we need to find the formula for y in terms of x.
We know that, y is inversely proportional to the cube of x.
So, it can be written as
=> y = k / x³
Where k is the constant.
To find the formula of y,
First we need to find the value of k,
By applying the value of x and y,
So,
=> 24 = k / (1/2)³
=> 24 = k / 1/8
=> 24/8 = k
=> k = 3
Therefore, the formula for y in terms of x is,
=> y = 3/ x³

40% of x is 35.
a) Write an equation that shows the relationship of 40%, x, and 35.
x=87.5
b) Use your equation to find x. Show your reasoning.
Answers
The equation 0.4x = 35 shows the relationship between 40% of x and 35.
What is equation?
An equation is a statement in mathematics that shows that two expressions are equal. It has two sides separated by an equal sign, which can contain variables, constants, and mathematical operations like addition, subtraction, multiplication, and division.
a) The relationship between 40% of x and 35 can be expressed as:
0.4x = 35
b) To solve for x, we can isolate x by dividing both sides of the equation by 0.4:
0.4x/0.4 = 35/0.4
x = 87.5
Therefore, x is equal to 87.5.
We can check our answer by substituting x=87.5 in the original equation:
0.4(87.5) = 35
35 = 35
The equation is true, which confirms that our solution is correct.

Find a recursive formula for the arithmetic sequence 24, 32, 40, 48… multiple choice in picture
Answers
To find the recursive formula for the arithmetic sequence 24, 32, 40, 48..., we need to identify the common difference between consecutive terms. In this case, we can see that the common difference is 8, since each term is obtained by adding 8 to the previous term.
Now, we can write the recursive formula for this sequence as follows:
a(n) = a(n-1) + 8
where a(n) represents the nth term in the sequence, and a(n-1) represents the previous term. This formula tells us that each term in the sequence can be obtained by adding 8 to the previous term.
The recursive formula for the arithmetic sequence 24, 32, 40, 48... is a(n) = a(n-1) + 8, where a(n) represents the nth term in the sequence and a(n-1) represents the previous term. This formula tells us that each term in the sequence can be obtained by adding 8 to the previous term.In this sequence, the common difference is 8 (32 - 24 = 8, 40 - 32 = 8, and so on). So, the recursive formula for this arithmetic sequence can be represented as:
a_n = a_(n-1) + 8, where a_n is the nth term and a_(n-1) is the previous term.

Consider the function f : R2 → R given by f(x1, x2) = x1 ^2+ x1x2 + 4x2 + 1. Find the Taylor approximation ˆf at the point z = (1, 1). Compare f(x) and ˆf(x) for the following values of x: x = (1, 1), x = (1.05, 0.95), x = (0.85, 1.25), x = (−1, 2). Make a brief comment about the accuracy of the Taylor approximation in each case.
Answers
The Taylor approximation of the function f at the point (1, 1) is obtained by finding the first and second partial derivatives of f with respect to x1 and x2. Using these derivatives.
the Taylor approximation is given by ˆf(x) = 3 + 4(x1 - 1) + 5(x2 - 1) + (x1 - 1)^2 + (x1 - 1)(x2 - 1) + 2(x2 - 1)^2. Comparing f(x) and ˆf(x) for different values of x shows that the Taylor approximation provides a good estimate near the point (1, 1), but its accuracy decreases as we move farther away from this point.
The Taylor approximation of a function is a polynomial that approximates the function near a given point. In this case, we find the Taylor approximation of f at the point (1, 1) by calculating the first and second partial derivatives of f with respect to x1 and x2. These derivatives provide information about the rate of change of f in different directions.
Using these derivatives, we construct the Taylor approximation ˆf(x) by evaluating the derivatives at the point (1, 1) and expanding the function as a polynomial. The resulting polynomial includes terms involving (x1 - 1) and (x2 - 1), representing the deviations from the point of approximation.
When comparing f(x) and ˆf(x) for different values of x, we can assess the accuracy of the Taylor approximation. Near the point (1, 1), where the approximation is centered, the approximation provides a good estimate of the function. However, as we move farther away from this point, the approximation becomes less accurate since it is based on a local linearization of the function.
In summary, the Taylor approximation provides a useful tool for approximating a function near a given point, but its accuracy diminishes as we move away from that point.
