Step-by-step explanation:

there is answer in the image above

The price of the next model will be $59,964, and the price increase will be $2,964.

To calculate the amount of the price increase, we need to multiply the current price by the percentage increase:

Price increase = 5.2% * $57,000

Price increase = 0.052 * $57,000

Price increase  = $2,964

So, the price of the next model will be:

Next model price = $57,000 + $2,964

Next model price  = $59,964

Hence, the price of the next model will be $59,964, and the price increase will be $2,964.

Based on the calculation, it appears that Matti had approximately 94 bottles of 0.5 litres and 11 bottles of 0.7 litres in the last patch of moonshine that he sold.

To solve the problem using the determinant method (Cramer's rule), we need to set up a system of equations based on the given information and then solve for the unknowns, which represent the number of 0.5 litre bottles and 0.7 litre bottles.

Let's denote the number of 0.5 litre bottles as x and the number of 0.7 litre bottles as y.

From the given information, we can set up the following equations:

Equation 1: 0.5x + 0.7y = 16.5 (total volume of moonshine)

Equation 2: 8x + 10y = 246 (total earnings from selling moonshine)

We now have a system of linear equations. To solve it using Cramer's rule, we'll find the determinants of various matrices.

Let's calculate the determinants:

D = determinant of the coefficient matrix

Dx = determinant of the matrix obtained by replacing the x column with the constants

Dy = determinant of the matrix obtained by replacing the y column with the constants

Using Cramer's rule, we can find the values of x and y:

x = Dx / D

y = Dy / D

Now, let's calculate the determinants:

D = (0.5)(10) - (0.7)(8) = -1.6

Dx = (16.5)(10) - (0.7)(246) = 150

Dy = (0.5)(246) - (16.5)(8) = -18

Finally, we can calculate the values of x and y:

x = Dx / D = 150 / (-1.6) = -93.75

y = Dy / D = -18 / (-1.6) = 11.25

However, it doesn't make sense to have negative quantities of bottles. So, we can round the values of x and y to the nearest whole number:

x ≈ -94 (rounded to -94)

y ≈ 11 (rounded to 11)

Therefore, based on the calculation, it appears that Matti had approximately 94 bottles of 0.5 litres and 11 bottles of 0.7 litres in the last patch of moonshine that he sold.

Question

Matti is making moonshine in the woods behind his house. He’s selling the moonshine in two different sized bottles: 0.5 litres and 0.7 litres. The price he asks for a 0.5 litre bottle is 8€, for a 0.7 litre bottle 10€. The last patch of moonshine was 16.5 litres, all of which Matti sold. By doing that, he earned 246 euros. How many 0.5 litre bottles and how many 0.7 litre bottles were there? Solve the problem by using the determinant method (a.k.a. Cramer’s rule).

Answer:

A, C, and D

Step-by-step explanation:

A) (4x + 3) (2x + 6) is equal to 8x² + 30x + 18 because when you multiply two binomials, you use the distributive property. The distributive property states that for any numbers a, b, and c, a(b + c) = ab + ac. So, (4x + 3) (2x + 6) can be rewritten as (4x)(2x) + (4x)(6) + (3)(2x) + (3)(6). This can further be simplified to 8x² + 24x + 18.

C) 2(4x² + 15x + 9) is equal to 8x² + 30x + 18 because when you multiply a number by a binomial, you use the distributive property. The distributive property states that for any numbers a, b, and c, a(b + c) = ab + ac. So, 2(4x² + 15x + 9) can be rewritten as 2(4x²) + 2(15x) + 2(9). This can further be simplified to 8x² + 30x + 18.

D) 4(2x² + 7x + 4) is equal to 8x² + 30x + 18 because when you multiply a number by a binomial, you use the distributive property. The distributive property states that for any numbers a, b, and c, a(b + c) = ab + ac. So, 4(2x² + 7x + 4) can be rewritten as 4(2x²) + 4(7x) + 4(4). This can further be simplified to 8x² + 28x + 16.

Answer:

For #5: There are 3 children and 4 adults.

Step-by-step explanation:

Let x= number of children

y= number of adults

y = x + 1

x + y = 7

x + (x+1) = 7

x + x + 1 = 7

2x + 1 = 7

2x = 7 - 1

2x = 6

x = 6/2

x = 3

y = x + 1

y = 3 + 1

y = 4

Therefore, the number of children is 3 and the adults are 4.

The histogram in Figure 2.16 shows that the distribution of waiting times is skewed to the right and not symmetrical.

Histograms are visual representations of the distribution of a dataset.

In order to determine whether the empirical rule is appropriate for describing the distribution of bank customer waiting times, we need to examine the histogram in Figure 2.16.

Looking at the histogram, we can see that the distribution of waiting times is not perfectly symmetrical.

The shape of the histogram is not exactly bell-shaped, which is what we would expect if the data were normally distributed. Instead, it is skewed to the right.

In conclusion, the histogram in Figure 2.16 indicates that the empirical rule is not appropriate for describing the distribution of bank customer waiting times. This is because the waiting times are not normally distributed and do not follow a symmetrical, bell-shaped curve.

One hose can fill a small swimming pool in 75 minutes. Two hoses will fill the pool in 30 minutes when working together.

Given, the volume ( the space occupied by an solid object)  per minute

Smaller hose fills  the pool in 75 minutes. (1/75)

A larger one can fill the pool in 50 minutes. (1/50)

So, together they will fill = (1/ 75 ) + (1/50) , the lcm of 75 and 50 is 150

                                            =  (2/150) + (3/150)

What is binomial probability?

In an experiment with twο pοssible οutcοmes, the likelihοοd οf exactly x successes οn n repeated trials is knοwn as the binοmial prοbability (cοmmοnly called a binοmial experiment).

Given that ,

p = 0.5

1 - p = 0.5

n = 10

Using binomial probability formula ,

P(X = x) = (n C x) * px * (1 - p)n - x

P(X = x) = (10 C x) * 0.5x * (0.)510 - x

p1= P(X = 6)

= (10 C 6) * 0.56 * (0.)510 - 6

= 0.2051        

p2=P(X = 6)

= P( 5.5< x <6.5 )

= P((5.5 - 5)/ 1.5811) < (x -μ ) / σ< (6.5 - 5) / 1.5811 )

The density in g/cm³ of an object that has a mass of 2.60 x 10⁶ mg and a volume of 0.095 Liters (L) is A 27.4.

We know that 1 Kg = 1000 g

Let's convert the mass in mg to grams.

(2.60 x 10⁶) mg = 2.60 x 10³ g

Now, we need to find the density of the object in g/cm³.

Density (p) = Mass (m) / Volume (V)

In g/cm³, the density can be given as

p = m / V

The mass is given as 2.60 x 10³ g and the volume is given as 0.095 L

p = (2.60 x 10³ g) / (0.095 L) = 27368.42105 g/L

We know that 1 L = 1000 cm³

Let's convert the density from g/L to g/cm³ by dividing it by 1000.

p = 27368.42105 / 1000 = 27.37 g/cm³ (approx)
