16 points

Hi there !

What is his  score?

6×4 - 4×2 =

= 24 - 8

= 16 points

Good luck !

Answer:

marks awarded for each correct answer = 4

marks awarded for each incorrect answer = -2

No.of Sunil's correct answer = 6

therefore, mark of Sunil's correct answer = 6 x 4 = 24

No.of Sunil's incorrect answer = 4

therefore, mark of Sunil's incorrect answer = 4 x -2 = -8 (here + and - is                                                                                                                  multiplied therefore the final answer will be -)

Sunil's total score = 24(positive marks) - 8(negative marks)

                               =24-8 = 16

This also is an integer question right?       ^_^                                                                                                                                                                  

There were 1706 people living in the village in 2005

The equation of the function is given as:

y = 110x + 56

Where

x is the number of years since 1990

When there were 1706 people living in the village. it means that:

y = 1706

So, we have:

110x + 56 = 1706

Subtract 56 from both sides

110x = 1650

Divide both sides by 110

x = 15

So, the year is

year = 15 + 1990

Evaluate

Year = 2005

Hence, there were 1706 people living in the village in 2005

Answer:

She has to get a 5

Step-by-step explanation:

So basically you have the numbers 4, 4, and 3.

To get a mean is the average, so we need to balance out the 3.

To balance it out, we add a 5.

We would have to get 16 points for it to be a mean of 4, 4 + 4 + 3 + 5 = 16.

Therefore, the equation for the LSRL is: Y = 0.018x + 29.82 and  (a)Y = 0.9175x + 22.49 is not the LSRL for the given data.

To find the least squares regression line (LSRL) for the given data, we need to calculate the slope and intercept of the line. The formula for the slope is:

b = r * (Sy / Sx)

where r is the correlation coefficient between x and y, Sy is the standard deviation of y, and Sx is the standard deviation of x. The formula for the intercept is:

a =Y - b *X

where Y is the mean of y, and X is the mean of x.

Using the given data, we can calculate the values of r, Sy, and Sx as follows:

x: 4 4 7 12 13 20

y: 23 28 30 40 28 41

Mean of x, X = (4+4+7+12+13+20)/6 = 10

Mean of y,Y= (23+28+30+40+28+41)/6 = 30

Sx = sqrt([∑(x-X)^2]/(n-1)) = sqrt([((4-10)^2 + (4-10)^2 + (7-10)^2 + (12-10)^2 + (13-10)^2 + (20-10)^2)]/5) = 6.615

Sy = sqrt([∑(y-Y)^2]/(n-1)) = sqrt([((23-30)^2 + (28-30)^2 + (30-30)^2 + (40-30)^2 + (28-30)^2 + (41-30)^2)]/5) = 7.989

r = ∑(x-X)(y-Y)/sqrt([∑(x-X)^2][∑(yY)^2])

= ((-67) + (-6-2) + (-30) + (210) + (3*-2) + (1011))/sqrt([((-6)^2 + (-6)^2 + (-3)^2 + (2)^2 + (3)^2 + (10)^2)][(7^2 + 2^2 + 0^2 + 10^2 + 2^2 + 11^2)])

= 0.015

Plugging in these values, we can calculate the slope of the LSRL as:

b = 0.015 * (7.989 / 6.615) = 0.018

And the intercept as:

a = 30 - 0.018 * 10 = 29.82

Therefore, the equation for the LSRL is:

Y = 0.018x + 29.82

for #7, all we have to do is -8+(-6), since again it says sum so we add. the sum of these values are -14. for the second part, because it says "product" this means we multiply! and when we multiply -2 by 4, we get -8. this would lead us to believe that the sum is 4 less than. we can check it by subtracting positive 4 from the  negative 8, or -8-4, which would give us -12.

for #11, all i really did was plug it into a calculator, and for the first one, i got 4, and for the second one i got -4. this would give us a difference of 8, and to check all we would have to do is add the 8 to the negative 4, or -4+8=4.

The rate of bacterial population increase is related to the size of the current population. If there were initially 4,000 people present, there will be 8,000 people present in 60 minutes. The number of bacteria will reach 63,000 after 4 hours.

1. There are 4000 bacteria in the initial population.

2. The number of bacteria doubles to 8000 after 60 minutes.

3. There are 16000 bacteria after two hours.

4. There are 32000 bacteria after three hours.

5. There are 63000 bacteria after 4 hours.

A particular kind of virulent bacteria's rate of growth in a culture is being investigated. It has been noted that the bacterial population's growth rate is related to the quantity present. It is possible to compute that 63,000 bacteria will be present after 4 hours if the starting population of 4000 bacteria quadrupled during the first 60 minutes. The original population can be multiplied by 2 every hour to determine this. The population will double to 8,000 after the first hour. By the end of the second hour, there will be 16,000 people living there. The population will double to 32,000 after the third hour. By the end of the fourth hour, there will be 63,000 people living there. Consequently, there will be 63,000 germs total in the environment after 4 hours. As the population of the bacteria in the culture doubles every hour, this demonstrates their exponential growth rate.

Actually, the statement √3² = 4 is not correct. The square root of 3 squared (√3²) is equal to 3, not 4.

The square root (√) of a number is a mathematical operation that gives you the value which, when multiplied by itself, equals the original number. In this case, the number is 3 squared, which is 3 multiplied by itself.

When we take the square root of 3², we are essentially finding the value that, when squared, gives us 3². Since 3² is equal to 9, we need to find the value that, when squared, equals 9. The positive square root of 9 is 3, which means √9 = 3.

Therefore, √3² is equal to the positive square root of 9, which is 3. It is essential to recognize that the square root operation results in the principal square root, which is the positive value. In this case, there is no need for trigonometric substitution as the calculation involves a simple square root.

Using trigonometric substitution is not necessary in this case since it involves a simple square root calculation. The square root of 3 squared is equal to the absolute value of 3, which is 3.

Therefore, √3² = 3, not 4.

According to Siegler, the pattern of learning math concepts involves a gradual development and refinement of strategies. Siegler's theory, known as the overlapping waves model, suggests that learners use multiple strategies simultaneously and gradually shift towards more efficient ones over time. This process allows for a better understanding and application of math concepts, ultimately leading to improved problem-solving skills.

According to Siegler, the pattern of learning math concepts involves a gradual progression from using counting strategies to more efficient and accurate strategies. Children initially rely on counting strategies to solve math problems, such as counting fingers or objects. As they progress, they begin to use more advanced strategies, such as decomposition or mental math, which allow them to solve problems more quickly and accurately. Siegler also emphasizes the importance of practice and repetition in developing math skills and the role of feedback and instruction in promoting learning. Overall, Siegler's theory suggests that children's math skills develop through a combination of innate abilities and environmental factors, including exposure to math concepts and opportunities for practice and instruction in time.

Using standard heats of formation,the standard enthalpy change for the given reaction is -124.5 kJ/mol.

The standard enthalpy change for the reaction NH4NO3(aq) → N2O(g) + 2H2O(l) can be calculated using the standard heats of formation.

First, we need to identify the standard heats of formation for each compound involved in the reaction. The standard heat of formation (ΔHf°) is the enthalpy change that occurs when one mole of a compound is formed from its elements in their standard states at a given temperature and pressure.

The standard heats of formation for NH4NO3(aq), N2O(g), and H2O(l) are as follows:
- NH4NO3(aq): -365.5 kJ/mol
- N2O(g): 81.6 kJ/mol
- H2O(l): -285.8 kJ/mol

Next, we need to determine the stoichiometric coefficients of the compounds in the balanced equation. From the equation, we can see that 1 mole of NH4NO3(aq) produces 1 mole of N2O(g) and 2 moles of H2O(l).

Now, we can calculate the standard enthalpy change using the formula:
ΔH = Σ(nΔHf° products) - Σ(mΔHf° reactants)

Plugging in the values, we have:
ΔH = (1 mol × 81.6 kJ/mol) + (2 mol × -285.8 kJ/mol) - (1 mol × -365.5 kJ/mol)
   = 81.6 kJ/mol - 571.6 kJ/mol + 365.5 kJ/mol
   = -124.5 kJ/mol

Therefore, the standard enthalpy change for the given reaction is -124.5 kJ/mol.

There are 144 ways to list the digits {1, 1, 2, 2, 3, 4, 5} such that two identical digits are not in consecutive positions.

We have to list the digits {1, 1, 2, 2, 3, 4, 5} so that two identical digits are not in consecutive positions. We can use the knowledge of permutations and combinations to solve this problem. We can start by selecting the positions for the distinct digits, i.e., (3, 4, 5). There are 3 distinct digits, so there are 3! = 6 ways to arrange them.

Once we have placed the distinct digits, we can place the two 1's and two 2's in the remaining positions such that no two identical digits are in consecutive positions. To do this, we can use the following approach:

We can start by placing one of the 1's. There are 4 positions available for the first 1.

We can then place one of the 2's. There are 3 positions available for the first 2.

We can then place the second 1. There are 2 positions available for the second 1.

We can then place the second 2. There are 1 positions available for the second 2.

Therefore, the total number of ways to list the digits {1, 1, 2, 2, 3, 4, 5} such that two identical digits are not in consecutive positions is:
