Naeem ate 14/24 of the pizza in total.

To find out how much pizza Naeem ate, let's work step by step.

First, let's calculate how much pizza Naeem had left on Sunday. On Saturday, he had 5/12 of the pizza left after dinner.

To find out how much he ate on Sunday, we need to find 2/5 of the amount left on Saturday.

To do this, we multiply 5/12 by 2/5. Multiplying the numerators (2 * 5) gives us 10, and multiplying the denominators (12 * 5) gives us 60. So, Naeem ate 10/60 of the pizza on Sunday.

To simplify this fraction, we can divide both the numerator and denominator by their greatest common divisor, which is 10. So, 10/60 simplifies to 1/6.

Therefore, Naeem ate 1/6 of the pizza on Sunday.

To find out how much pizza Naeem ate in total, we add the amount he ate on Saturday (5/12) to the amount he ate on Sunday (1/6).

To add fractions, we need a common denominator. The least common multiple of 12 and 6 is 12.

Multiplying the numerator and denominator of 5/12 by 2 gives us 10/24.

Adding 10/24 to 1/6 gives us 10/24 + 4/24, which equals 14/24.

Therefore, Naeem ate 14/24 of the pizza in total.

Answer:

3/4 is the answer to ur question

'A study that compares standardized test scores before and after a course is taken' is  most likely to be dependent samples.

The most likely dependent samples are those in which the measurements are taken from the same individual or group of individuals in different conditions. Based on this, the answer is:

'a study that compares standardized test scores before and after a course is taken'

In this case, the same individuals are being measured twice (before and after taking the course), and their scores are being compared. The scores are dependent because they are being measured from the same individuals in both conditions.

The other options are less likely to involve dependent samples:

a) In comparing wait times at two different emergency rooms, the measurements are independent because they are taken from different individuals at different locations.

b) In comparing salaries earned by men and women in the same job position, the measurements are independent because they are taken from different individuals.

c) In comparing weight gain for puppies who eat two different brands of food, the measurements are independent because they are taken from different individuals (puppies) who are being exposed to different conditions (different brands of food).

To evaluate the integral, let's break it down step by step.

\(\int\limits^2_0 {(2/6)sec(x)} \, dx\)

First, let's simplify the expression:

\(\int\limits^2_0 (1/3)sec(x) dx\)

To evaluate this integral, we can use the formula for the integral of the secant function:

∫sec(x)dx = ln |sec(x) + tan(x)| + C

Applying this formula to our integral, we get:

\((1/3)\int\limits^2_0 {sec(x)} \, dx\)

= (1/3)[ln |sec(2) + tan(2)| - ln |sec(0) + tan(0)| ]

Since sec(0) = 1 and tan(0) = 0, the second term becomes zero:

(1/3)[ln |sec(2) + tan(2)| - ln(1)]

= (1/3) ln |sec(2) + tan(2)|

Therefore, the exact value of the integral is (1/3) ln |sec(2) + tan(2)|.

The required differential equation is x'' + 0.67x' + 2.33x = 0.

The standard differential equation, which we use to represent a damped spring-mass system is written as:

m(d²x/dt²) + c(dx/dt) + kx = 0,

where m is the mass, c is the damping coefficient, k is the spring constant, x is the d²splacement, and the equation has been derived with respect to time t.

In the question, the

mass m = 3 kg,

spring constant k = 7 N/m,

damping constant c = 2N-s/m.

Differentiating x with time t, we take (d²x/dt²) = x'', and (dx/dt) = x'.

Substituting all the values in the standard differential equation, we get:

3x'' + 2x' + 7x = 0,

or, x'' + (2/3)x' + (7/3)x = 0 {Dividing by 3},

Step-by-step explanation:

she was the one who made it faster to do the work!!

The reciprocal of the time it takes to do the work together is the sum of

the reciprocal of the time it takes to do the work individually.

Reasons

Let R represent the number of days it will take Rohan, S, the number of

days it would take Sohan, and M, the number of days it would take Mohan

to do the work alone, we have;

\(\displaystyle \frac{1}{30} = \mathbf{ \frac{1}{R} + \frac{1}{S}}\)...(1)

\(\displaystyle \frac{1}{24} = \mathbf{ \frac{1}{M} + \frac{1}{S}}\)...(2)

\(\displaystyle \mathbf{ \frac{1}{40}} = \frac{1}{R} + \frac{1}{M}\)...(3)

Subtract equation (1) from equation (2) and add the result to equation (3), we have;

\(\displaystyle \frac{1}{24} - \frac{1}{30} =\displaystyle \left( \frac{1}{M} + \frac{1}{S} \right) - \left(\frac{1}{R} + \frac{1}{S}\right) =\displaystyle \left( \frac{1}{M} - \frac{1}{R} \right)\)

\(\displaystyle \frac{1}{24} - \frac{1}{30} + \frac{1}{40} =\displaystyle \left( \frac{1}{M} - \frac{1}{R} \right) + \frac{1}{R} + \frac{1}{M} = \frac{2}{M}\)

\(\displaystyle \mathbf{\frac{1}{24} - \frac{1}{30} + \frac{1}{40}} = \frac{1}{30} = \frac{2}{M}\)

M = 2 × 30 = 60

\(\displaystyle \frac{1}{24} = \mathbf{\frac{1}{M} + \frac{1}{S}}\)

\(\displaystyle \frac{1}{24} = \frac{1}{60} + \frac{1}{S}\)

\(\displaystyle \frac{1}{24} - \frac{1}{60} =\frac{1}{40} = \frac{1}{S}\)

\(\displaystyle \frac{1}{S} = \frac{1}{40}\)

\(\displaystyle \frac{1}{40} = \frac{1}{R} + \frac{1}{M}\)

(x - 5)(x - 5)

Step-by-step explanation:

\( {x}^{2} - 10x + 25 \: is \: the \: expansion \\ of \: {(x - 5)}^{2} \\ {(x - 5)}^{2} = (x - 5)(x - 5)\)

The complete factorization of the quadratic expression x² - 10x + 25 is (x - 5)(x - 5). Hence the first option is the right choice.

A quadratic expression of the form ax² + bx + c is factored by using the mid-term factorization method, which suggests that b should be broken in such two components that their product = ac. After this, we can factorize using the grouping method.

In the question, we are asked to factor the quadratic expression x² - 10x + 25 completely.

Comparing x² - 10x + 25 to ax² + bx + c, we get a = 1, b = -10, and c = 25.

To factor the expression we will use the mid-term factorization method, and try to break b in such two numbers whose product = ac.

Now, ac = 1 * 25 = 25. b = -10, which can be broken as -5, and -5.

Therefore, we can write the given expression as:

x² - 10x + 25

= x² - 5x - 5x + 25, mid-term factorization

= x(x - 5) -5(x - 5), grouping

= (x - 5)(x - 5), grouping.

Therefore, the complete factorization of the quadratic expression x² - 10x + 25 is (x - 5)(x - 5). Hence the first option is the right choice.

The general solution of the system is:

x(t) = Ae^(4t) + Be^(14t)

y(t) = Ce^(4t) + De^(14t)

To find the general solution of the given system:

x' = 7x + 3y

y' = 3x + 11y

We can start by finding the eigenvalues of the coefficient matrix:

|7-λ   3 |

|3    11-λ|

Setting the determinant of the matrix equal to zero, we get:

(7-λ)(11-λ) - (33) = 0

Expanding this equation and simplifying, we get:

λ^2 - 18λ + 56 = 0

Factoring this quadratic equation, we get:

(λ-14)*(λ-4) = 0

Therefore, the eigenvalues are λ1 = 14 and λ2 = 4.

Next, we can find the eigenvectors associated with each eigenvalue. For λ1 = 14, we need to solve the equation:

|7-14   3 |   | -7   3 |   |1|

|3    11-14| * |  3  -3 | = |0|

Simplifying this equation, we get:

-7x + 3y = 1

3x - 3y = 0

Solving these equations simultaneously, we get:

x = -1/2, y = -1/2

Therefore, the eigenvector associated with λ1 = 14 is:

v1 = (-1/2, -1/2)

Similarly, for λ2 = 4, we need to solve the equation:

|7-4   3 |   | 3   3 |   |1|

|3    11-4| * |-1   1 | = |0|

Simplifying this equation, we get:

3x + 3y = 1

-x + y = 0

Solving these equations simultaneously, we get:

x = 1/6, y = 1/6

Therefore, the eigenvector associated with λ2 = 4 is:

v2 = (1/6, 1/6)

Using these eigenvectors, we can find the general solution of the system:

x(t) = c1v1exp(λ1t) + c2v2exp(λ2t)

y(t) = c1v1exp(λ1t) + c2v2exp(λ2t)

Substituting the given values of λ1, λ2, v1, and v2, we get:

x(t) = c1*(-1/2, -1/2)exp(14t) + c2(1/6, 1/6)exp(4t)

y(t) = c1(-1/2, -1/2)exp(14t) + c2(1/6, 1/6)*exp(4t)

Simplifying this expression, we get:

x(t) = (-c1/2)*exp(14t) + (c2/6)*exp(4t), y(t) = (-c1/2)*exp(14t) + (c2/6)*exp(4t)

Therefore, the general solution of the system is:

x(t) = Ae^(4t) + Be^(14t)

y(t) = Ce^(4t) + De^(14t)

Main Answer: The point estimate for the true proportion of interested patrons  is 0.5660 and the true proportion of patrons interested in attending the showing of Puppet Master is between 0.4241 and 0.7079.

Supporting Question and Answer:

How is the margin of error calculated in constructing a confidence interval for a proportion?

The margin of error is calculated by multiplying the z-score corresponding to the desired confidence level by the standard error of the proportion, which is determined by the formula sqrt((p ×q) / n)

where p is the point estimate of the proportion, q is 1 - p, and n is the sample size.

Body of the Solution:

a) The point estimate for the true proportion of interested patrons can be calculated by dividing the number of patrons who said they would come (30) by the total number of patrons surveyed (53):

Point Estimate = Number of interested patrons / Total number of patrons = 30 / 53

≈ 0.5660 (rounded to four decimal places)

b) To construct a 95% confidence interval for the true proportion of interested patrons, we can use the following formula:

Confidence Interval = Point Estimate ± Margin of Error

The margin of error depends on the desired level of confidence and is calculated using the standard error formula:

Standard Error = √((p × (1 - p)) / n)

Where:

p= Point estimate of the proportion (0.5660)

n = Sample size (53)

Let's calculate the standard error:

Standard Error = √((0.5660 ×(1 - 0.5660)) / 53)

≈ 0.0724 (rounded to four decimal places)

The margin of error is determined by multiplying the standard error by the appropriate z-score for the desired level of confidence. For a 95% confidence level, the z-score is approximately 1.96.

Margin of Error = 1.96 × Standard Error

= 1.96 × 0.0724 ≈ 0.1419 (rounded to four decimal places)

Now we can calculate the confidence interval:

Confidence Interval = Point Estimate ± Margin of Error

= 0.5660 ± 0.1419

≈ 0.4241 to 0.7079

Interpreting the confidence interval: "We are 95% confident that the true proportion of patrons interested in attending the showing of Puppet Master is between 0.4241 and 0.7079.

Final Answer:  

a)The point estimate for the true proportion of interested patrons  is 0.5660

b)The true proportion of patrons interested in attending the showing of Puppet Master is between 0.4241 and 0.7079.

What is rate?

A rate is a measure of the amount of change of one quantity with respect to another quantity, typically expressed as a ratio.

The derivative of a function represents its rate of change at a particular point. In this case, S represents the monthly sales of Bluetooth headphones, and its derivative S' represents the rate of change of sales. If S' is increasing, it means that the rate of change of sales is getting larger over time.

Mathematically, this means that the second derivative S" (which represents the rate of change of the rate of change) is positive, since an increasing slope of the original function (S') corresponds to a positive value for the second derivative.

Therefore, S" > 0 indicates that the rate of change of sales is increasing.

Answer:

93.75 pounds

Step-by-step explanation:

Set up a proportion where x is the weight of a person on Earth:

\(\frac{200}{32}\) = \(\frac{x}{15}\)

Cross multiply and solve for x

32x = 3000

x = 93.75

So, the person would weigh 93.75 pounds on Earth

On Earth, a person weighing 93.75 pounds would weigh around 15 pounds on the moon.

A mathematical assessment of two numbers is called a proportion. If two sets of provided numbers rise or fall in the same relation, then the ratios are said to be directly proportional to each other.

If a person who weighs 200 pounds on Earth would weigh about 32 pounds on the moon, we can set up the following proportion to find the weight of a person on Earth who would weigh 15 pounds on the moon:

200 pounds : 32 pounds = x pounds : 15 pounds

200 pounds / 32 pounds = x pounds / 15 pounds

⇒ 200/32 = x/15

Apply the Cross-multiplication operation, we get:

⇒ 200 × 15 = 32 × x

Solving for x, we get:

⇒ x = (200 × 15) / 32

⇒ x = 3000/32

Apply the division operation

⇒ x = 93.75 pounds

Therefore, a person who weighs 93.75 pounds on Earth would weigh about 15 pounds on the moon.
