Answer:

$12,060

Step-by-step explanation:

LET selling price be rep by x

since he made a profit of 12%, we then add to 100%

100% + 12% = 112%.

to find the selling price, we multiply cost price  by 112%

112% x $10768 =

112 / 100  x $10,768

=  1.12 x $10,768  = 12,060

selling price = $12,060.

Answer: 1/18

Step-by-step explanation:

the probability that you roll a 4 on a standard die is 1/6 because there is 6 sides then the probability of rolling a 1 or a 3 is 2/6 or one third. then multiply 1/3 by 1/6 and you get the final answer of 1/18 :)

Step-by-step explanation:

y = ax^n + bx^(n-1) ... + z

(0, 1) tells us that the constant term z = 1.

because x = 0 eliminates all other terms. and as the sum is 1, that means z = 1.

for the other pairs I strongly suspect

(-1, 3) : 2×(-1)² + 1 = 2×1 + 1 = 3

(-2, 9) : 2×(-2)² + 1 = 2×4 + 1 = 9

so, the fitting equation is

y = 2x² + 1

Anna spends $20 less than her father on the 500 km trip.

Given: Anna's car uses 5 Liters per 100 km

Her father's car uses 7 Liters per 100 km

Cost of petrol is $2 per Liter

Anna spends less than her father on a 500 km trip. To find by how less Anna had spent than her father.

Let's solve the question:

According to the question Anna's car uses:

5 Liters per 100 km or

100 km is travelled with 5 Liters of petrol.

Then 1 km is travelled by 5 / 100 Liters of petrol.

1 km is travelled by 1 / 20 Liters of petrol by Anna.

According to the question Anna's father car uses:

7 Liters per 100 km or

100 km is travelled by 7 Liters of petrol.

Then 1 km is travelled by 7 / 100 Liters of petrol.

1 km is travelled by 7 / 100 Liters of petrol by Anna's father.

Now 500 km is travelled by:

        500 × 1 / 20 Liters of petrol = 25 Liters of petrol.

        Therefore 500 km is travelled by 25 Liters of petrol.

        500 × 7 / 100 Liters of petrol = 35 Liters of petrol

        Therefore, 500 km is travelled by 35 Liters of petrol.

Cost of petrol is $2 per Liter.

Anna: She consumes 25 Liters of petrol for the 500 km journey.

Her cost is 25 × 2 = 50

Anna's cost = $50

Anna's father: He consumes 35 Liters of petrol for the 500 km journey

His cost is 35 × 2 = 70

Anna's father cost = $70

Therefore, the difference in cost = (Anna's father cost - Anna's cost) = ($70 - $50) = $20.

Hence Anna spends $20 less than her father on the 500 km trip.

Anna spends $20 less than her father on the 500 km trip.

fuel used by Anna =  5 Liters per 100 km

Fuel used by father = 7 Liters per 100 km

Cost of petrol = $ 2 per Liter

we need to find by how less Anna had spent than her father.

By using the unitary method, we get that:

Anna:

500 × 1 / 20 Liters of petrol = 25 Liters of petrol.

500 km is travelled by 25 Liters of petrol.

Father:

500 × 7 / 100 Liters of petrol = 35 Liters of petrol

500 km is travelled by 35 Liters of petrol.

Anna:

Cost =  25 × 2 = $ 50

Anna's father:

Cost = 35 × 2 = $ 70

Difference in cost = $ 70 - $ 50 = $ 20.

Therefore, Anna spends $20 less than her father on the 500 km trip.

Step-by-step explanation:

Transformation is a method required to resize or change the orientation of a given shape or figure. The required answer is:

i. Statements b and d would map Shape l onto Shape II

​ii. Statements a, c, e, and f does not map Shape l onto Shape II​

Transformation is a method required to resize or change the orientation of a given shape or figure. The types of transformation are translation, reflection, rotation, and dilation. The translation is a method that requires moving every point in a given shape in the same direction and same unit.

Reflection is a method that involves flipping a given figure about a given reference point or line. Rotation is a method that required turning a given figure at an angle about a reference point. Dilation is a method in which the length of the sides of the figure is either increased or decreased. Thus the answers to the question are listed as follows:

a. a reflection across the y-axis, followed by a 90° clockwise rotation about the origin, and then a translation left 6 units. Does not Map Shape l onto Shape II

EXPLANATION:

Given;

We are given a parallel pair of lines m and n, and a transversal that cuts both lines.

Required;

We are required to find the value of x.

Step-by-step solution;

When a pair of parallel lines are cut by a transversal, the angle formed by the point of intersection of one line and the transversal is equal to that formed by the other line and the transversal when they both lie on the same side of the transversal.

This means on the diagram given;

This means angle 167 on line n is equal to angle 167 on line m. These are called corresponding angles.

The same applies to angle x on the line m and the other angle on line n. They both are also corresponding angles.

Next, take note that angles that lie on either side of a vertex where two lines intersect are called vertically opposite angles (or just opposite angles).

Therefore, angle x = 167 and angle 167 = x.

Answer:

The number of

Quarters = q = 58 quarters

Nickels = n = 32 nickels

Step-by-step explanation:

It is important to note that:

A quarter is worth 25 cents = 0.25q

A nickel is worth 5 cents = 0.05n

George has only Quarters and nickels in his piggy bank.

Let the number of

Quarters = q

Nickels = n

He has a total of 90 coins.

Hence,

q + n = 90.... Equation 1

q = 90 - n

The value of the coins is $16.10.

Hence,

0.25q + 0.05n = 16.10....Equation 2

We substitute 90 - n for q in Equation 2

0.25(90 - n) + 0.05n = 16.10

22.5 - 0.25n + 0.05n = 16.10

Collect like terms

- 0.25n + 0.05n = 16.10 - 22.5

-0.2n = - 6.4

n = -6.4/-0.2

n = 32 nickels

Solving for q

q = 90 - n

q = 90 - 32

q = 58 quarters

Therefore, the number of

Quarters = q = 58 quarters

Nickels = n = 32 nickels

To test the hypothesis H0: σ = 2.1 versus H1: σ > 2.1, where σ is the population standard deviation, we need to calculate the test statistic and determine the p-value.

a. To compute the test statistic, we use the formula: test statistic = (s - σ0) / (s/√n). where s is the sample standard deviation, σ0 is the hypothesized population standard deviation under the null hypothesis, and n is the sample size. Substituting the given values, we have: test statistic = (2.8 - 2.1) / (2.8 / √17) ≈ 1.703

b. To determine the p-value, we use technology such as statistical software or a t-distribution table. Since the sample size is small (n = 17) and the population is assumed to be normally distributed, we use the t-distribution. Using the t-distribution with degrees of freedom (df) = n - 1 = 16 and the test statistic of 1.703, we find the p-value associated with the right-tail probability. From the t-distribution table or using statistical software, the p-value is approximately 0.0545.

c. The researcher decides to test the hypothesis at the significance level α = 0.05. Since the p-value (0.0545) is greater than the significance level, we fail to reject the null hypothesis. There is not enough evidence to conclude that the population standard deviation is greater than 2.1. Therefore, the researcher will not reject the null hypothesis and will accept that the population standard deviation is equal to 2.1, as stated in the null hypothesis.

Answer:

(f o g)(-5) = -53

Step-by-step explanation:

Step 1: Define

f(x) = -2x - 7

g(x) = -4x + 3

Step 2: Find f(g(x))

f(g(x)) = -2(-4x + 3) - 7

f(g(x)) = 8x - 6 - 7

f(g(x)) = 8x - 13

Step 3: Find (f o g)(-5)

(f o g)(-5) = 8(-5) - 13

(f o g)(-5) = -40 - 13

(f o g)(-5) = -53

The pH of the resulting solution, obtained by diluting 10 ml of the acidic solution to a final volume of 1000 ml, is 6.

The dilution equation states that the concentration of a solute remains constant when the volume of the solution changes.

Since the dilution factor is

1000 ml / 10 ml = 100

The concentration of H+ ions in the resulting solution is 1/100 times the concentration in the original solution.

The pH scale is logarithmic, meaning that each whole pH unit represents a tenfold change in the concentration of H+ ions.

Since the pH of the original solution is 4, which represents a concentration of 10^(-4) mol/L, the concentration of H+ ions in the resulting solution is 1

0^(-4) mol/L / 100 = 10^(-6) mol/L.

To calculate the pH of the resulting solution, we take the negative logarithm base 10 of the concentration:

pH_result = -log10(10^(-6))

= -(-6) (logarithm property)

= 6

Therefore, the pH of the resulting solution, obtained by diluting 10 ml of the acidic solution to a final volume of 1000 ml, is 6.

The dilution process has decreased the concentration of H+ ions, resulting in a less acidic solution with a higher pH value.
