Answer: 3.078139077

Step-by-step explanation:

Use the 1st digit 2 from dividend 2367800.

Since 2 is less than 769231, use the next digit 3 from dividend 2367800 and add 0 to the quotient.

Use the 2nd digit 3 from dividend 2367800.

Since 23 is less than 769231, use the next digit 6 from dividend 2367800 and add 0 to the quotient.

Use the 3rd digit 6 from dividend 2367800

Since 236 is less than 769231, use the next digit 7 from dividend 2367800 and add 0 to the quotient.

Use the 4th digit 7 from dividend 2367800.

Since 2367 is less than 769231, use the next digit 8 from dividend 2367800 and add 0 to the quotient.

Use the 5th digit 8 from dividend 2367800.

Since 23678 is less than 769231, use the next digit 0 from dividend 2367800 and add 0 to the quotient.

Use the 6th digit 0 from dividend 2367800.

Since 236780 is less than 769231, use the next digit 0 from dividend 2367800 and add 0 to the quotient.

Use the 7th digit 0 from dividend 2367800.

Find closest multiple of 769231 to 2367800. We see that 3×769231=2307693 is the nearest. Now subtract 2307693 from 2367800 to get reminder 60107.

Add 3 to quotient.

Quotient: 3

Answer:

Rolling a six-sided number cube 24 times and recording if a 4 comes up

Step-by-step explanation:

Answer:

80 m

Step-by-step explanation:

From the question;

Initial velocity, u, = 20m/s

Time = 15 s

deceleration= -2.5 m/s² ------negative acceleration

The formula to apply is;

v²=u²+2as

where v is the final velocity = 0m/s and s is the total distance travelled.

Applying the formula as;

v²=u²+2as

0²=20²+ 2*-2.5*s

0=400+ -5s

0=400-5s

5s= 400

s= 400/5 = 80

s= 80 m

The total distance travelled is  80 m.

Step-by-step explanation: Reflection across x axis only flips the sign of y coordinate

"What is the total number of miles that the teacher ran last week and this week, if he ran a total of 5 3/4 miles last week and 4/5 of that distance this week?" is 10 13/20 miles.

To find the total number of miles that the teacher ran last week and this week, we need to:

Determine how many miles the teacher ran this week.

Add that number to the total number of miles the teacher ran last week.

Let's start by finding out how many miles the teacher ran this week:

The teacher ran 4/5 of the total number of miles he ran last week, which means he ran:

(4/5) x 5 3/4 miles = 4 3/5 miles

Next, we can add the number of miles the teacher ran last week to the number of miles he ran this week to find the total number of miles he ran:

5 3/4 miles + 4 3/5 miles = 10 13/20 miles

Therefore, the teacher ran a total of 10 13/20 miles last week and this week combined.

Step-by-step explanation:

I think this is it but 6*8 is 48....I used a little logic so hopefully this is right

Answer:

4030

Step-by-step explanation:

if 9× 7 = 3545 then it 7 × 5, 9× 5 which gives 3545

4x3 = 3× 5, 4×5 which gives 1520

so 6× 8 will give 8×5, 6×5 = 4030

Answer:

(x^3 + 3x^2 - 2x + 7)/x- 2

Expand the numerator in the above expression

(x^3 + 5x^2 - 2x^2 + 8x - 10x - 16 + 23)/(x - 2)

Rearrange the terms of the numerator in the above expression

(x^3 + 5x^2 + 8x - 2x^2 - 10x - 16 + 23)/(x- 2)

Factorize the numerator in the above expression

[x(x^2 + 5x + 8) - 2(x^2 + 5x + 8) + 23]/(x - 2)

Factor out x^2 + 5x + 8

[(x -2)(x^2 + 5x + 8) + 23]/(x - 2)

Split the fractions

(x -2)(x^2 + 5x + 8)/(x - 2) + 23/(x - 2)

Divide the common factors

(x^2 + 5x + 8) + 23/(x - 2) hope this help btw your welcome

Depends on the specific data and coefficients of the quadratic regression model used.

The coefficient of determination, denoted as R-squared (R2), is used to calculate the percentage of variation in productivity explained by the quadratic regression model. R-squared is a statistical measure that represents the proportion of the variance explained by an independent variable or variables in a regression model for a dependent variable.

R-squared is calculated by comparing the total sum of squares (TSS) and the residual sum of squares (RSS):

TSS = Σ(y - ȳ)^2

RSS = (y - - x - b*x2)2.

where y is the actual productivity value, is the mean of the productivity values, x is the independent variable, and b are the quadratic regression model coefficients.

R-squared can be calculated using the formula:

R2 = 1 minus (RSS/TSS)

We can then convert R-squared to a percentage to get the percentage of variation in productivity explained by the quadratic regression model.

As a result, the answer to this question is dependent on the specific data and quadratic regression model coefficients used.

To determine which expressions have a positive value based on the positions of a and b, we need to consider the signs of a and b and then evaluate each expression:

(-b) is positive if b is negative

(a+b) is positive if both a and b are positive or if a is negative and b is greater than the absolute value of a

(a-b) is positive if a is greater than b

(ab) is positive if both a and b have the same sign (either both positive or both negative)

(-b) is negative if b is positive

(a) is positive if a is positive

So, based on the positions of a and b, the expressions that have a positive value are:

(a+b), if both a and b are positive or if a is negative and b is greater than the absolute value of a

(a), if a is positive

Therefore, the correct answers are:

a+b

a

Para hacer las porciones para 32 personas, multiplique cada cantidad de ingrediente por 4 ya que la receta proporciona 8 porciones y 8 * 4 = 32

Papa seca = \(\frac{1}{2} *4\)

                     = 2 papas secas

Cerdo = \(\frac{1}{2} *4\)

       = 2 kg de carne de cerdo

Cebollas = 1 * 4

            = 4 cebollas grandes

Aji panca = 3 * 4

               = 12 cucharadas de aji panca

Ajo molido = \(1\frac{1}{2} *4\)

                       = \(\frac{3}{2} *4\)

                       = 6 cucharadas de ajo molido

Sal = 1 * 4

The probability is that less than 329 of the selected students use iPhones at a local college, and 80% of all students use iPhones.

Thus, the probability of using an iPhone by a student is p = 0.8 and the probability of not using an iPhone is q = 1 - p = 0.2. Here, the sample size is n = 400. Because the sample size is large, we can use the normal approximation to the binomial distribution.

Therefore, the mean and variance of the number of students using iPhones in the sample of 400 students are as follows:μ = np = 400 × 0.8 = 320σ² = npq = 400 × 0.8 × 0.2 = 64The standard deviation is σ = √σ² = √64 = 8

Now, we can use the standard normal distribution to calculate the probability that less than 329 students use iPhones in the sample of 400 students. We calculate the z-score:z = (x - μ) / σ = (329 - 320) / 8 = 1.125Since we are calculating the probability that less than 329 students use iPhones, we need to find the area under the standard normal curve to the left of z = 1.125.

We can use standard normal distribution tables to find this probability. We find the value of 0.8708. So, the probability that less than 329 students use iPhones is 0.8708.

Therefore, Probability = 0.8708 (correct to four decimal places).

Thus, the probability that less than 329 of the selected students use iPhones is 0.8708.b) Probability that more than 370 of the selected students use iPhone

Here, the sample size is n = 450.

Using the same method, the mean and variance of the number of students using iPhones in the sample of 450 students are as follows:μ = np = 450 × 0.8 = 360σ² = npq = 450 × 0.8 × 0.2 = 72

The standard deviation is σ = √σ² = √72 ≈ 8.49

Now, we can use the standard normal distribution to calculate the probability that more than 370 students use iPhones in the sample of 450 students.

We calculate the z-score:z = (x - μ) / σ = (370 - 360) / 8.49 = 1.177Since we are calculating the probability that more than 370 students use iPhones, we need to find the area under the standard normal curve to the right of z = 1.177. We can use standard normal distribution tables to find this probability.

We find the value of 0.1198.

So, the probability that more than 370 students use iPhones is 0.1198. Therefore, Probability = 0.1198 (correct to four decimal places)Thus, the probability that more than 370 of the selected students use iPhones is 0.1198.
