Answer:

5 Hours

Step-by-step explanation:

8 x 5 = 40.

Heather wants to spend $35 dollars at most. She has a discount for $5 dollars off, so basically we do 40 -5, which equals $35.

The population standard deviation is known to be $11. construct the 98% confidence interval, then the 98% confidence interval for mean (a , b) = ( $16.8 , $16.3 )

A confidence interval is a range of values that describes the uncertainty surrounding an estimate.

Confidence interval can be defined as a range of values so defined that there is a specified probability that the value of a parameter lies within it.

The confidence interval of a statistical data can be written as.

CI = \(x\) ± z \(\frac{r}{\sqrt{n} }\)           (Equation-1)

Where,

CI = Confidence interval

x = sample mean

z = Confidence level value

r = sample standard deviation

n = sample size

Given that,

Mean x = $16.6

Standard deviation r = $11

Number of samples n = 7472

Confidence interval = 98%

z(at 98% confidence) = 2.33

Substituting the values we have equation-1,

= $16.6 ± 2.33 ( \(\frac{11}{\sqrt{7472} }\) )

= $16.6 ± 2.33 ( $\(\frac{11}{86.44}\) )

= $16.6 ± 2.33 ( $ 0.127 )

= $16.6 ± $0.295

= $16.6 + $0.295 ,      $16.6 - $0.295

= ( $16.8 , $16.3 )

Therefore,

The population standard deviation is known to be $11. construct the 98% confidence interval, then the 98% confidence interval for mean (a , b) = ( $16.8 , $16.3 )

Answer:

Step-by-step explanation:

Let the points scores by Denny = x

Point score by Keshawn  = 3 * x = 3x

Total score = 280

x + 3x = 280

   4x   = 280     {Divide both sides by 4}

4x/4  = 280/4

     x = 70

3x = 3*70 = 210

Point scored by Keshawn = 210

If Denny's point total is 70, Keshawn's point is 210

1 foot = 12 inches

56 inches / 12 inches = 4.66 feet = 4 feet and 8 inches

Answer:

4 feet and 8 inches

Step-by-step explanation:

To convert a high number of inches to feet you divide it by 12 since 12 inches makes 1 foot.

So 56÷12 = 4 reminder 8

The remainder we keep it as inches

So our answer is 4 feet and 8 inches.

Circumference of a circle having radius of 27 yard can be found using the formula, π = 2(Area of Circle)/r, which is C = 169.6 yd

Given:

radius of circle = 27 yd

Thus:

Area = πr² = π(27)²

Area = 2,290.2 yd²

Circumference of a circle without using π = 2(2,290.2)/27

= 169.6 yd.

Answer:

Step-by-step explanation:

The z-score corresponding to a sample mean of 78 is -1.20 if distributed population with mu equal to 80 and sigma equal to 10.

Sample (n) = 36

Distributed population = 80

Sigma = 10

We can use the central limit theorem to determine the sampling distribution of the sample mean and normally distributed with a mean a standard deviation equal to the population standard deviation.

To calculate  the z-score to a sample mean of 78, the formula used here is

z = (x - μ) / (σ / √n)

z = (78 - 80) / (10 / √36)

z  = -2 / 1.67

z = -1.20

Therefore, we can conclude that the z-score corresponding to a sample mean of 78 is -1.20.

100 same-day tickets were sold for the cost using equation.

To solve this problem, we can use a system of two equations with two variables. Let x be the number of advance tickets sold and y be the number of same-day tickets sold. Then we have:

x + y = 600   (equation 1: total number of tickets sold)
50x + 30y = 28000   (equation 2: total amount paid for tickets)

We can solve for x and y by using elimination or substitution. Here's one way to do it using substitution:
From equation 1, we have y = 600 - x. Substitute this into equation 2:

50x + 30(600 - x) = 28000

Simplify and solve for x:
50x + 18000 - 30x = 28000
20x = 10000
x = 500

So 500 advance tickets were sold. To find the number of same-day tickets, we can substitute x = 500 into equation 1:

500 + y = 600
y = 100

So 100 same-day tickets were sold.

One of the four fundamental arithmetic processes, or how numbers are combined to create new numbers, is division. The additional processes are multiplication, addition, and subtraction. What is long division? Long division is a common division method in mathematics that can be easily performed by hand and is appropriate for dividing multi-digit Hindu-Arabic numerals (Positional notation). It divides a division issue into several simpler steps.The dividend is divided by the divisor, as is the case in all division problems, and the quotient is the final result. It makes it possible to conduct calculations involving arbitrary large numbers by following a set of easy steps. When the divisor has only one number, short division, the condensed version of long division.

The probability of both rice and carrots being served with dinner is 23.4%.

The probability of Alvin's mother serving rice with dinner can be expressed using the formula P(Rice) = 0.78. This means that the probability of Alvin's mother serving rice with dinner is 78%. The probability of Alvin's mother serving carrots with dinner can be expressed using the formula P(Carrots) = 0.30. This means that the probability of Alvin's mother serving carrots with dinner is 30%. To calculate the combined probability of both rice and carrots being served with dinner, we can use the formula P(Rice and Carrots) = P(Rice) * P(Carrots) = 0.78 * 0.30 = 0.2340.

Step-by-step explanation:

The sum to n terms of a geometric series is

\(S_{n}\) = \(\frac{a(1-r^{n}) }{1-r}\)

Here a = 6144 and r = \(\frac{a_{2} }{a_{1} }\) = \(\frac{3072}{6144}\) = \(\frac{1}{2}\) , then

\(S_{10}\) = \(\frac{6144(1-(\frac{1}{2}) ^{10}) }{1-\frac{1}{2} }\)

The B coordinate vector for \($-1+2t$\) will be:

\(\[\begin{bmatrix}c_1 \\c_2 \\c_3 \\\end{bmatrix}\]\)

What is linear algebra?

Linear algebra is a branch of mathematics that deals with the study of vector spaces, linear transformations, and systems of linear equations. It focuses on the properties and operations of vectors and matrices, as well as their relationships and transformations.

To find the B coordinate vector for a given vector in the standard basis, you need to express that vector as a linear combination of the basis vectors of B. Here's how you can approach it:

1. Given vector:\($-1+2t$\)

2. Write the given vector as a linear combination of the basis vectors of B:

\($-1+2t = c_1(1-2t+t^2) + c_2(3-5t+4t^2) + c_3(2t+3t^2)$\)

3. Equate the coefficients of corresponding terms:

 \($-1 + 2t = c_1 + 3c_2$\\\\ $0t = -2c_1 - 5c_2 + 2c_3$ \\ \\$0t^2 = c_1 + 4c_2 + 3c_3$\)

4. Solve the system of equations to find the values of \(c_1$, $c_2$, and $c_3$.\)

By solving the system of equations, you can find the values of \(c_1$, $c_2$, and $c_3$\) , which will form the B coordinate vector for the given vector \(-1+2t$.\) Substitute the values back into the linear combination equation to obtain the B coordinate vector.

Once you have the values of \($c_1$, $c_2$, and $c_3$,\) the B coordinate vector for \($-1+2t$\) will be:

\(\[\begin{bmatrix}c_1 \\c_2 \\c_3 \\\end{bmatrix}\]\)
