What is the Next number in this series 7 11 19 35?
Answer:
67
Step-by-step explanation:
we have a gap between 1st and 2nd terms of 4. a gap between 2nd and 3rd of 8. 16 for next gap. the gap doubles every time.
so we expect gap between 4th and 5th terms to be 2 X 16 = 32.
35 + 32 = 67. that is the next number in the sequence.
How do you write an equation in slope intercept form for a parallel line?
Parallel slope intercept form is a form of linear equation that describes a line parallel to a given line with slope m.
The equation for a line parallel to the line with equation y = mx + b is y = mx + b + c, where c is any constant.
1. Start with the equation of the original line in slope-intercept form, y = mx + b
2. To make a parallel line, add a constant c to the y-intercept, so the equation is y = mx + b + c
3. That's it! You now have an equation for a parallel line in slope-intercept form.

Find f(a), f(a + h), and the difference quotient f(a + h) − f(a) h , where h ≠ 0. f(x) = 6x2 + 4
f(a) = ?
f(a + h) = ?
f(a + h) − f(a) =
All f(a), f(a + h), and the difference quotient f(a + h) − f(a) h is equal to 2.
The continuity of a function at a point requires that the limit of the function exists and is equal to the function value at that point.
So, to define f(3) to be 2 in order to ensure that f is continuous at x = 3, we need to check if the limit of f as x approaches 3 exists and is equal to 2.
Let's assume that f is defined on an open interval containing x = 3. Then, we need to check if the limit of f(x) as x approaches 3 is equal to 2. In other words, we need to check if:
lim (x → 3) f(x) = 2
If this limit exists and is equal to 2, then we can define f(3) to be 2 and f will be continuous at x = 3.
However, if the limit does not exist or is not equal to 2, then we cannot define f(3) to be 2 to ensure continuity at x = 3.

To find the volume generated by rotating the region bounded by the curves y = 9e^(-x^2), y = 0, x = 0, and x = 1 about the y-axis, we can use the method of cylindrical shells.
The volume of each cylindrical shell is given by the formula V = 2πrhΔx, where r represents the distance from the axis of rotation to the shell, h represents the height of the shell, and Δx represents the thickness of the shell.
In this case, we will integrate with respect to x since the curves are defined in terms of x. The radius r of each shell is the x-coordinate, and the height h is given by the difference in y-values between the two curves: h = 9e^(-x^2) - 0 = 9e^(-x^2).
To calculate the volume, we integrate the expression 2πx(9e^(-x^2)) with respect to x from x = 0 to x = 1:
V = ∫[0,1] 2πx(9e^(-x^2)) dx
Evaluating this integral will give us the volume of the region generated by the rotation.

If gasoline costs $ 3.77 per gallon when you pay with a credit card, but $0.08 per gallon less if you pay with cash, how much do you save by filling up a 8-gallon tank and paying for it with cash?
Answer:
$0.64
Step-by-step explanation:
Cost for 8 gallons of gas
Credit Card at $3.77/gal
Cash at $(3.77 - 0.08)/gal: $3.69/gal
(8 gal)*($3.77/gal) = $30.16

Stephen curry has attempted 813 shots so far this season. of those shots 460 have been attempts at 3-point shots. if steph takes a shot, what is the
probability that it will be a three-point shot?
The probability that Stephen Curry's shot will be a three-point shot is approximately 0.566 or 56.6%.
What is the probability that Stephen Curry's shot will be a three-point shot if he has attempted 460 three-point shots out of a total of 813 shots this season?To calculate the probability of an event, you divide the number of favorable outcomes (in this case, the number of three-point shot attempts) by the total number of possible outcomes (the total number of shot attempts).
In this scenario, Stephen Curry attempted 460 shots from three-point range out of a total of 813 shots.
By dividing these two values, we get the probability of approximately 0.566 or 56.6%. This means that there is a 56.6% chance that Stephen Curry's shot will be a three-point shot.

An independent basic service set (IBSS) consists of how many access points?
An independent basic service set (IBSS) does not consist of any access points.
In an IBSS, devices such as laptops or smartphones connect with each other on a peer-to-peer basis, forming a temporary network. This type of network can be useful in situations where there is no existing infrastructure or when devices need to communicate with each other directly.
Since an IBSS does not involve any access points, it is not limited by the number of access points. Instead, the number of devices that can be part of an IBSS depends on the capabilities of the devices themselves and the network protocols being used.
To summarize, an IBSS does not consist of any access points. Instead, it is a network configuration where wireless devices communicate directly with each other. The number of devices that can be part of an IBSS depends on the capabilities of the devices and the network protocols being used.

You pick a card at random without putting the 1st card back you pick a second card at random what is the probability of picking a 7 and then picking a 7
Given:
There are four cards numbered as
\(6,\text{ }7,\text{ }8,\text{ and }9.\)Required:
We have to find the probability of picking a 7 and then picking a 7.
Explanation:
When you pick the first card there are four possibilities out of which only one card is numbered as 7.
Therefore, the probability of picking a 7 is
\(\frac{1}{4}\)Before picking the second card you have put back the first card. So when you pick the second card there are four possibilities out of which only one card is numbered as 7.
Therefore, the probability of picking a 7 is
\(\frac{1}{4}\)Hence the probability of picking a 7 and then picking a 7 is
\(\frac{1}{4}\times\frac{1}{4}=\frac{1}{16}\)Final answer:
Hence the final answer is
\(\frac{1}{16}\)
the weights of bags of cement are normally distributed with a mean of 53 and a standard deviation of 2 a. what is the likelihood that a randomly selected individual bag has a weight greater than 50
The likelihood that a randomly selected bag of cement weighs more than 50 is approximately 93.32%
When dealing with normally distributed data, we use the mean and standard deviation to determine the likelihood of certain events occurring. In this case, the mean weight of bags of cement is 53 with a standard deviation of 2.
To find the likelihood that a randomly selected bag has a weight greater than 50, we need to calculate the z-score for 50. The z-score tells us how many standard deviations away a particular value is from the mean.
z = (X - μ) / σ
where X is the value we're interested in (50), μ is the mean (53), and σ is the standard deviation (2).
z = (50 - 53) / 2 = -1.5
A z-score of -1.5 means that a weight of 50 is 1.5 standard deviations below the mean. To find the likelihood of a bag weighing more than 50, we can use a z-table or a calculator to find the area to the right of this z-score.
Looking up a z-score of -1.5, we find that the area to the left is approximately 0.0668, which means the area to the right (the likelihood of a bag weighing more than 50) is:
1 - 0.0668 = 0.9332
Thus, the likelihood that a randomly selected bag of cement weighs more than 50 is approximately 93.32%.

why is the answer false?
Answer True or False. The sum of quadratic functions is also a quadratic function.
The answer is False. The sum of quadratic functions is not always a quadratic function.
A quadratic function is a function of the form f(x) = ax^2 + bx + c, where a, b, and c are constants. When you add two quadratic functions together, the resulting function may not have the same form as a quadratic function.
For example, consider the quadratic functions f(x) = x^2 and g(x) = -x^2. If you add these two functions together, you get h(x) = f(x) + g(x) = x^2 + (-x^2) = 0. The resulting function is a constant function, which is not a quadratic function.
Therefore, the sum of quadratic functions is not always a quadratic function, making the statement false.
