To graph the line with slope -1 passing through the point (-2,4), we can use the point-slope form of the equation of a line, which is:

where m is the slope of the line, and (x1, y1) is the given point on the line. Substituting the given values, we get:

Simplifying this equation, we get:

Now we can graph this line by plotting the given point (-2,4), and then using the slope of -1 to find one or more additional points on the line. We can do this by starting at the given point and then moving one unit down (since the slope is negative) and one unit to the right (since the slope is -1). This gives us the point (-1,3). We can then connect these two points to graph the line.

If the brain volumes (cm³) of 20 brains have a mean of 1085.2 cm³ and a standard deviation of 125.6 cm³. For such data: it is significantly low for a brain because 1386.4 cm³ is less than the upper limit.

Mean = 1085.2 cm³

Standard deviation = 125.6 cm³

Hence,

Lower limit = Mean - 2 x Standard deviation

Lower limit  =1085.2 - 2 x 125.6

Lower limit =1161.2 - 251.2

Lower limit  =910

Upper Limit = Mean + 2 x Standard deviation

Upper Limit = 1161.2 +  2 x 125.6

Upper Limit =1161.2 +251.2

Upper Limit =1412.4

The limit of values is from 910 to 1412.4.

A value below 910 will be is considered low and a value above 1412.4  will be considered high

Therefore 1386.4 cm³ is less than the upper limit. Thus it is significantly low for a brain.

Answer:

Step-by-step explanation:

The first equation is incorrect.

The second equation is correct.

The third equation is correct.

Let's go through each equation and determine whether it is correct or incorrect:

(b²+7b-9)+(4b-6b²) = -8b² + 14b-9

To determine if this equation is correct, we need to simplify both sides and check if they are equal.

On the left side:

(b²+7b-9)+(4b-6b²) = b² - 6b² + 7b + 4b - 9 = -5b² + 11b - 9

On the right side:

-8b² + 14b - 9

Comparing both sides, we can see that -5b² + 11b - 9 is not equal to -8b² + 14b - 9. Therefore, the equation is incorrect.

(4a+6)-(3a²-9a+1)=-3a²+ 13a +5

Again, we need to simplify both sides of the equation and check if they are equal.

On the left side:

(4a+6)-(3a²-9a+1) = 4a + 6 - 3a² + 9a - 1 = -3a² + 13a + 5

On the right side:

-3a² + 13a + 5

Comparing both sides, we can see that -3a² + 13a + 5 is equal to -3a² + 13a + 5. Therefore, the equation is correct.

(12c-8c²)+(5c²- 10c) = -3c²+2c

Again, let's simplify both sides and compare them.

On the left side:

(12c-8c²)+(5c²- 10c) = 12c - 8c² + 5c² - 10c = -3c² + 2c

On the right side:

-3c² + 2c

Comparing both sides, we can see that -3c² + 2c is equal to -3c² + 2c. Therefore, the equation is correct.

Using arithmetic operation, the total weight of 15 boxes of Cremora is obtained as 5.625 kilograms.

What is arithmetic operation?

A subject of mathematics known as arithmetic operations deals with the study and use of numbers in all other branches of mathematics. Basic operations including addition, subtraction, multiplication, and division are included.

Use the arithmetic operation of division.

If 1 box of Cremora measures 375 grams, then convert that to kilograms by dividing by 1000 -

375 grams = 0.375 kilograms

So, each box of Cremora weighs 0.375 kilograms.

Use the arithmetic operation of multiplication.

To find the total weight of 15 boxes of Cremora, multiply this weight by the number of boxes -

Total weight = 15 boxes x 0.375 kilograms per box

Total weight = 5.625 kilograms

Therefore, the total weight of 15 boxes of Cremora is 5.625 kilograms.

The rules of operations states that we deal with parentheses first. So, inside the parentheses, we have, 2 times 3. Multiply that. That gives us 6. So now, the equation looks like this:

(6)^2 + 5^2

Now we have to work with the exponents. So, square both numbers.

(6)^2 = 36

5^2 = 25

Now we have:

36 + 25

Now we add. 36 + 25 = 61

1. In this case, we want the reliability to be 95%, so the probability of not breaking down is 0.95.

2. Probability of no breakdowns = (reliability of a single machine)^3. Probability of at least one breakdown = 1 - Probability of no breakdowns

1. To determine how often the computer should be scheduled for maintenance, we need to consider the reliability and the desired level of operational condition. Since the duration for trouble-free operation follows a gamma distribution with a mean of 40 days, this means that, on average, the computer can operate for 40 days before a breakdown occurs.

To ensure operational condition with a 95% probability, we can calculate the maintenance interval using the concept of reliability. The reliability represents the probability that the machine will not break down within a certain time period. In this case, we want the reliability to be 95%, so the probability of not breaking down is 0.95.

Using the gamma distribution parameters, we can find the corresponding reliability for a specific time duration. By setting the reliability equation equal to 0.95 and solving for time, we can find the maintenance interval:

reliability = 0.95

time = maintenance interval

Using reliability and the gamma distribution parameters, we can calculate the maintenance interval.

2. To calculate the probability that at least one of the three machines will break down within the first scheduled maintenance time, we can use the complementary probability approach.

The probability that none of the machines will break down within the first scheduled maintenance time is given by the reliability of a single machine raised to the power of the number of machines:

Probability of no breakdowns = (reliability of a single machine)^3

Since the breakdown times between the machines are statistically independent, we can assume that the reliability of each machine is the same. Therefore, we can use the reliability calculated in the first part and substitute it into the formula:

Probability of at least one breakdown = 1 - Probability of no breakdowns

By calculating this expression, we can determine the probability that at least one of the three machines will break down within the first scheduled maintenance time.

Therefore, to the nearest tenth of a year, the person must leave the money in the bank for 3.9 years until it reaches 7600 dollars.

A percent is a way of expressing a number as a fraction of 100. It is represented by the symbol %. Percentages are often used to represent proportions, rates, or changes in values.  Percentages can also be used to compare two quantities. This allows us to compare the relative size of the increase, regardless of the actual dollar amount involved.

Here,

We can use the formula for compound interest to solve this problem. The formula is:

A = P(1 + r/n)*(nt)

where A is the amount of money after t years, P is the principal (the initial amount invested), r is the annual interest rate as a decimal, n is the number of times the interest is compounded per year, and t is the time in years.

In this problem, we know that P = 4500, r = 0.0525 (since the interest rate is 5.25%), n = 365 (since interest is compounded daily), and we want to find t when A = 7600.

Substituting these values into the formula, we get:

7600 = 4500(1 + 0.0525/365)*(365t)

Dividing both sides by 4500, we get:

1.6889 = (1 + 0.0525/365)*(365t)

Taking the natural logarithm of both sides, we get:

ln(1.6889) = ln[(1 + 0.0525/365)*(365t)]

Using the properties of logarithms, we can simplify the right-hand side:

ln(1.6889) = 365t ln(1 + 0.0525/365)

Dividing both sides by 365 ln(1 + 0.0525/365), we get:

t = ln(1.6889) / [365 ln(1 + 0.0525/365)]

Using a calculator, we find that t is approximately 3.9 years (rounded to one decimal place).
