A bakery sells, on average, 100 special breads per day and collects with these sales, on average, R $ 300.00. It was found that the quantity of special breads sold daily increases if the price is reduced, according to the equation q = 400 - 100p, in which q represents the quantity of special breads sold daily and p, its price in reais. In order to increase the flow of customers, the bakery manager decided to run a promotion. To do so, it will modify the price of special bread so that the quantity to be sold daily is as large as possible, without decreasing the average daily collection on the sale of this product. The price p, in reais, of the special bread in this promotion should be in the range

a) R $ 0.50 p b) R $ 1.50 p c) R $ 2.50 p d) R $ 3.50 p e) R $ 4.50 p

i) 4 more gallons of petrol will be needed to complete the journey.

ii) The cost of the petrol for the 420 km journey is GH¢55.00.

i) To determine the number of gallons of petrol needed to complete the journey, we can calculate the total distance that can be covered with the available petrol and then subtract it from the total distance of the journey.

Given that the car consumes 1 gallon of petrol for every 30 km, we can calculate the distance that can be covered with 10 gallons of petrol by multiplying 10 (gallons) by 30 (km/gallon):

Distance covered with 10 gallons = 10 * 30 = 300 km

To find the remaining distance that needs to be covered, we subtract the distance covered with the available petrol from the total distance of the journey:

Remaining distance = Total distance - Distance covered with available petrol

Remaining distance = 420 km - 300 km = 120 km

Since the car consumes 1 gallon of petrol for every 30 km, we can determine the additional gallons of petrol needed by dividing the remaining distance by 30:

Additional gallons needed = Remaining distance / 30 = 120 km / 30 km/gallon = 4 gallons

Therefore, the driver will need 4 more gallons of petrol to complete the journey.

ii) To calculate the cost of the petrol for the journey of 420 km, we need to multiply the total number of gallons used for the journey by the cost per gallon.

Given that a gallon of petrol costs GH¢5.50, and the total number of gallons used for the journey is 10 (given in the problem), we can calculate the cost using the formula:

Cost of petrol = Total gallons used * Cost per gallon

Cost of petrol = 10 gallons * GH¢5.50/gallon = GH¢55.00

Therefore, the cost of the petrol for the journey of 420 km is GH¢55.00.

Answer:

1/32

Step-by-step explanation:

Assuming that each question is independent, the probability of Yasmine answering a question correctly is 1/2, since each question has two possible answers (true or false) and she has a 50/50 chance of guessing correctly. Therefore, the probability of her answering all five remaining questions correctly is:

(1/2)^5 = 1/32

So the probability of Yasmine answering the five remaining questions correctly is 1/32, or approximately 0.03125, or about 3.125%.

Answer:

100%

Step-by-step explanation:

We know

She has answered 15 of her 20 questions correctly.

What is the probability that she will answer the five remaining questions correctly?

We take

15/15 = 100%

So, 100% she will answer the five remaining questions correctly.

Answer:

a). r = \(\frac{6}{7}\)

b). At least 5 terms should be added.

Step-by-step explanation:

Formula representing sum of infinite geometric sequence is,

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

Where a = first term of the sequence

r = common ratio

a). If the sum is seven times the value of its first term.

    \(7a=\frac{a}{1-r}\)

    \(7=\frac{1}{1-r}\)

    7(1 - r) = 1

    7 - 7r = 1

    7r = 7 - 1

    7r = 6

    r = \(\frac{6}{7}\)

b). Since sum of n terms of the geometric sequence is given by,

    \(S_{n}=\frac{a(1-r^{n})}{1-r}\)

If the sum of n terms of this sequence is more than half the value of the infinite sum.

\(\frac{a[1-(\frac{6}{7})^{n}]}{1-\frac{6}{7}}\) >  \(\frac{7a}{2}\)

\(\frac{1-(\frac{6}{7})^{n}}{1-\frac{6}{7}}> \frac{7}{2}\)

\(\frac{1-(\frac{6}{7})^{n}}{\frac{1}{7}}> \frac{7}{2}\)

\(1-(\frac{6}{7})^{n}> \frac{7}{2}\times \frac{1}{7}\)

\(1-(\frac{6}{7})^{n}> \frac{1}{2}\)

\(-(\frac{6}{7})^{n}> -\frac{1}{2}\)

\((\frac{6}{7})^{n}< \frac{1}{2}\)

\((0.85714)^{n}< (0.5)\)

n[log(0.85714)] < log(0.5)

-n(0.06695) < -0.30102

n > \(\frac{0.30102}{0.06695}\)

n > 4.496

n > 4.5

Therefore, at least 5 terms of the sequence should be added.

Veremos que la velocidad un minuto despues es 1,200 m/s.

Sabemos que la aceleración del cohete es constante, y es de 20 m/seg^2 (asumimos que el cohete tiene esta aceleración teniendo en cuenta la aceleración gravitatoria, es decir, 20m/seg^2 es la aceleración neta).

a(t) = 20m/seg^2.

Para obtener la velocidad, integramos la cantidad de arriba:

v(t) = (20 m/seg^2)*t + V

Donde V es la velocidad inicial del cohete, que sabemos es igual a cero.

v(t) = (20 m/seg^2)*t.

The difference between ANOVA and Z-test Hypothesis is the Z-test is employed to contrast the averages of single or dual populations, whereas ANOVA is utilized for assessing the means across three or more clusters.

The Z-test becomes possible in  the comparison of the mean of a sample to that of the population. It evaluates if there is statistical relevance in the difference between the mean of a sample and the mean of the whole population

In contrast, ANOVA is employed to contrast the averages of three or more separate groups. This assesses if there is a noteworthy distinction in the averages of said groups. The F-statistic in ANOVA is computed by assessing the disparity in variability between groups and the variability within groups.

The central angle measure, x, for the Baseball slice in the circle graph is 50.4 degrees.

Given that, a survey was conducted in which 2400 people were asked to name their favorite sport to watch and the table below shows their answers: Sport percentage of people are:

Football 29%

Soccer 9%

Baseball 14%

Basketball 8%

Hockey 8%

Other 32%

We need to find the central angle measure, x, for the Baseball slice in the circle graph.

For this, we need to use the formula that gives the central angle measure in degrees for a sector of a circle:

Central angle measure = (Percentage/100) × 360°

Now, using the above formula, we can calculate the central angle measure for each sport as shown below:

Football: (29/100) × 360° = 104.4°

Soccer: (9/100) × 360° = 32.4°

Baseball: (14/100) × 360° = 50.4°

Basketball: (8/100) × 360° = 28.8°

Hockey: (8/100) × 360° = 28.8°

Other: (32/100) × 360° = 115.2°

The sum of all central angle measures should be 360°, which is the measure of a full circle.

So we can check if the calculations are correct: 104.4° + 32.4° + 50.4° + 28.8° + 28.8° + 115.2° = 360°

We see that the sum is indeed 360°, so the calculations are correct. The central angle measure for the Baseball slice is 50.4°.

Therefore, the central angle measure, x, for the Baseball slice in the circle graph is 50.4 degrees.

Answer:

The work done to stretch or compress the spring is stored in the spring as elastic potential energy. The elastic potential energy of a spring is one half the product of its spring constant multiplied by the square of its deformation.

Step-by-step explanation:

0.05 Joule energy is stored in a spring with an elastic constant of 1000N/m when it is compressed 10cm.

Elastic potential energy is stored in the spring as a result of the work required to stretch or compress it. A spring's elastic potential energy is equal to one-half the sum of its spring constant times its deformation squared.

It is given that, a spring with an elastic constant of 1000N/m is compressed 10cm.​

The energy stored in the spring is,

E= 1/2Kx²

Where E is the energy stored, K is the spring constant and x is the spring compression.

Substitute the given value as

E =  1/2(1000)(0.01)²

E= 0.05 J

Thus, 0.05 Joule energy is stored in a spring with an elastic constant of 1000N/m when it is compressed 10cm.
