Answer:

each student gets 1 sheet. There are 73 sheets left.

Step-by-step explanation:

Each student only needs 1 sheet and so you just do 80-7 and you get 73

The steps are given below.

Given that an expression,

(8)(x) = (-8)(x-12)

x = 6

16x = 96

8x + 8x = -8x + 96 + 8x

8x = -8x + 96

16x/16 = 96/16

We need to put the steps in order to solve equation,

​The steps to solving the problem are as follows, in the right order:

1. Begin with the following equation: (8)(x) = (-8)(x-12)

2. Simplify the problem on both sides: 8x = -8(x-12)

3. Divide the terms between the parenthesis by -8: 8x = -8x + 96

4. On the right side of the equation, combine like terms: 8x + 8x = -8x + 96 + 8x

5. Simplify both sides by incorporating comparable terms: 16x = 96

6. 16x/16 = 96/16 is used to multiply both sides of the equation by 16.

7. Rephrase the formula as x = 6

Consequently, x = 6 is the answer to the equation.

Step-by-step explanation:

1. Since we know that Lila wants to use 1 cup of pretzels, we can multiply 1/2 x 1/2, which is 1.

2. Now that we multiplied 1/2 by 1/2, we have to multiply 1 1/4 by 1/2.

So 5/4 x 1/2 is 5/8.

3. Lila will need 5/8 cups of raisins.

The required probability that she'll use a cab exactly one time is  4/9.

probability is a part of math that arrangements with figuring out the probability of the event of an occasion.

Elizabeth lives in San Francisco and works in Mountain View.

In the first part of the day she has 3 transportation choices  (bus, cab, train) to work, and at night she has similar 3 options for her outing home.

All transportation  (bus, cab, train) are comparably liable to be chosen, and 1 of them should be chosen in the first part of the day and night, so we get:

P (bus) = P (taxi) = P (train) = 1/3.

We additionally have P(no taxi in night) = P(no taxi at morning) = 2/3

Presently, P(using taxi precisely once) = P(cab at morning and no taxi at night) + P(no taxi at morning and taxi at night)

= P(cab, no taxi) + P(no taxi, taxi)

= 1/3 × 2/3 + 2/3 × 1/3

= 2/9 + 2/9

= 4/9

Consequently, the probability that Elizabeth utilizes a taxi just once is 4/9.

Hi!

We can use point-slope form to solve this.

\(y-y_{1} =m(x -x_{1})\)

\(y_{1}\) and \(x_{1}\) will be from one of the points.

First, we have to find \(m\), the slope. We can use the slope equation to get this.

\(\frac{y_{1} -y_{2} }{x_{1} -x_{2} }\)

Plug in your points:

\(\frac{4-0}{8-(-8)} =\frac{4-0}{8+8} =\frac{4}{16} =\frac{1}{4}\)

Your slope is \(\frac{1}{4}\)

Now plug points and slope into point-slope equation. We will use (8, 4).

\(y-4=\frac{1}{4} (x-8)\)

Now, if you want to get it into y = mx + b form, you have to solve for y:

\(y-4=\frac{1}{4} (x-8)\)

\(y-4=\frac{1}{4} x-2\)

\(y=\frac{1}{4} +2\)

Your equation is \(y=\frac{1}{4} +2\)

The volume of the solid obtained when the region under the curve y = 5 arcsin(x), x ≥ 0, is rotated about the y-axis is 0.

To find the volume of the solid obtained by rotating the region under the curve y = 5 arcsin(x) about the y-axis, we can use the disk/washer method and integrate the cross-sectional area of the resulting disks or washers.

The cross-sectional area can be expressed as A(y) = πr^2, where r is the distance from the y-axis to the curve y = 5 arcsin(x). Since x = sin(y/5), we can express r as r = x = sin(y/5).

Using the formula for the volume of a solid of revolution, we have:

V = ∫[a to b] A(y) dy

= ∫[a to b] π(sin(y/5))^2 dy

To determine the limits of integration, we need to find the values of y where the curve intersects the y-axis. When x = 0, we have y = 0, so the lower limit of integration is a = 0. To find the upper limit of integration b, we solve the equation y = 5 arcsin(x) for x = 0:

0 = 5 arcsin(0)

0 = 5(0)

0 = 0

Since the curve intersects the y-axis at y = 0, the upper limit of integration is b = 0.

Now we can calculate the volume:

V = ∫[0 to 0] π(sin(y/5))^2 dy

= π∫[0 to 0] sin^2(y/5) dy

Using the identity sin^2θ = (1/2)(1 - cos(2θ)), we can rewrite the integral as:

V = π∫[0 to 0] (1/2)(1 - cos(2y/5)) dy

Integrating the above expression will give us the volume of the solid. However, since the limits of integration are both 0, the resulting volume will be zero.

Therefore, the volume of the solid is zero.

The point at which the two lines intersect should be labeled as point A.This is how perpendicular lines can be constructed using a point on the line.

To construct perpendicular lines using a point on the line, the following steps should be followed:

Step 1: Draw a line. This line is the line that needs to have a perpendicular line.

Step 2: Choose a point on the line. This point will be the starting point of the perpendicular line.

Step 3: Draw a straight line from the chosen point perpendicular to the first line. This line is the perpendicular line.

Step 4: Label the intersection of the two lines as point A.The key term to keep in mind here is perpendicular lines. Perpendicular lines are lines that intersect at a 90-degree angle.

When constructing perpendicular lines, it is important to have a point on the line to start with, as this will be the starting point of the perpendicular line. By drawing a straight line from the chosen point perpendicular to the first line, the perpendicular line is formed, intersecting the first line at a 90-degree angle.

The probability that a second call will not arrive in the next 20 seconds is approximately 0.2636 or 26.36%.

Poisson probability is a mathematical concept that describes the probability of a certain number of events occurring in a fixed interval of time or space, given a known average rate of occurrence. The Poisson probability distribution is named after French mathematician Siméon Denis Poisson, who introduced it in the early 19th century to model the occurrence of rare events, such as errors in counting or measurement, accidents, or phone calls.

The Poisson probability distribution is a discrete probability distribution that gives the probability of a certain number of events (x) occurring in a fixed interval (t), when the average rate of occurrence (λ) is known. The Poisson probability distribution assumes that the events occur independently and at a constant average rate over time or space. The formula for Poisson probability is:

P(x; λ) = (\(e^{-\lambda}\)) * λˣ) / x!

where:

P(x; λ) = the probability of x occurrences in a given interval, when the average rate is λ

e = a mathematical constant e (approximately 2.71828)

λ = it is the average rate of occurrence in the given interval

x = it is number of occurrences in the given interval

Given that calls for dial-in connections arrive at an average rate of four per minute and follow a Poisson distribution, we can use the Poisson probability formula to solve this problem. The Poisson probability formula is:

P(x; λ) =  (\(e^{-\lambda}\)) * λˣ) / x!

where:

P(x; λ) = the probability of x occurrences in a given interval, when the average rate is λ

e = a mathematical constant e (approximately 2.71828)

λ = the average rate of occurrence in the given interval

x = it is the number of occurrences in the given interval

In this problem, we are interested in finding the probability that a second call will not arrive in the next 20 seconds, given that a call has already arrived at the beginning of a one-minute interval. Since we are given the average rate of calls per minute, we need to adjust the interval to 20 seconds, which is 1/3 of a minute. Therefore, the average rate of calls per 20 seconds is:

λ = (4 calls/minute) * (1/3 minute) = 4/3 calls/20 seconds

Using the Poisson probability formula, we can calculate the probability of no calls arriving in the next 20 seconds:

P(0; 4/3) = ( \(e^{-4/3}\)* (4/3)⁰) / 0! = \(e^{-4/3}\) ≈ 0.2636

The standard normal curve, also known as the standard normal distribution or the z-distribution, is a specific probability distribution that follows a bell-shaped curve. The area under the standard normal curve to the right of z = 3 is approximately 0.0013.

For the area under the standard normal curve to the right of z = 3, we need to calculate the cumulative probability from z = 3 to positive infinity.

The standard normal distribution, also known as the z-distribution, has a mean of 0 and a standard deviation of 1. It is a symmetric bell-shaped curve that represents the distribution of standard scores or z-scores.

Using statistical tables or software, we can find the cumulative probability associated with z = 3, which represents the area under the curve to the left of z = 3.

The cumulative probability for z = 3 is approximately 0.9987.

For the area to the right of z = 3, we subtract the cumulative probability from 1.

Therefore, the area to the right of z = 3 is approximately 1 - 0.9987 = 0.0013.

In conclusion, the area under the standard normal curve to the right of z = 3 is approximately 0.0013.

This means that the probability of randomly selecting a value from the standard normal distribution that is greater than 3 is approximately 0.0013 or 0.13%.

The value of x that makes 25x^2 + 70x + c a perfect square trinomial is c = 1225.

To make the quadratic expression 25x^2 + 70x + c a perfect square trinomial, we need to determine the value of c.

A perfect square trinomial can be written in the form (ax + b)^2, where a is the coefficient of the x^2 term and b is half the coefficient of the x term.

In this case, a = 25, so b = (1/2)(70) = 35.

Expanding (ax + b)^2, we have:

(25x + 35)^2 = 25x^2 + 2(25)(35)x + 35^2

= 25x^2 + 70x + 1225.

We want to check that we can't solve this equation with x and y integers, to see that, we can start by isolating one of the variables:

2x^2 + 5y^2 = 14

5y^2 = 14 - 2x^2

y^2 = (14 - 2x^2)/5

y = ±√((14 - 2x^2)/5)

Now, trivially:

(14 - 2x^2)/5

Is not an integer for any integer value of x, and this happens because 5 is not a factor of 14, thus, for any integer value of x the value of y that we get is non integer, then there aren't two integers that solve the quadratic equation.
