Answer:

615,000

Step-by-step explanation:

When you "round to the nearest _____" regardless of what goes in the blank the steps are nearly always the same:

Identify which place value you are rounding to. The smaller the place value, the more accurate the final result will be.

Look to the next smallest place value, the digit to the right of the place value you're rounding to. For example, if you want to round to the nearest ten you'd look at the ones place.

If the digit in the next smallest place value is less than five (0, 1, 2, 3, or 4), you leave the digit you want to round to as-is. Any digits after that number (including the next smallest place value you just looked at) become zeros, or drop-off if they're located after the decimal point. This is called rounding down.

If the next smallest place value is greater than or equal to five (5, 6, 7, 8, or 9), you increase the value of the digit you're rounding to by one (+1). Just like before, any remaining digits before the decimal point become zeros, and any that are after the decimal point are dropped. This is called rounding up.

If the number is greater than or equal to 5, then we round up. If it is less than or equal to 4, we round down.

9 is greater than 5. We would round up.

The probability of x being greater than 18 (p(x > 18)) is equal to the probability of x being less than 18 (p(x < 18)) in a normal distribution.

In a normal distribution, the probability of an event happening to the left of the mean (μ) is equal to the probability of the event happening to the right of the mean. This means that if we know the probability of x being less than 18 (p(x < 18)), we can use the property of symmetry to determine the probability of x being greater than 18 (p(x > 18)).

Since the probability distribution of x is symmetric around the mean, the area under the probability density function (PDF) to the left of the mean is the same as the area to the right of the mean. Therefore, we can say:

p(x > 18) = p(x < 18)

In other words, the probability of x being greater than 18 is equal to the probability of x being less than 18 in a normal distribution.

The statement "P implies Q" is false under the following conditions: a) P is true and Q is false, and d) P is false and Q is true.

The statement "P implies Q" can be expressed as "if P, then Q." It is a conditional statement where P is the antecedent (the condition) and Q is the consequent (the result).

To determine when the statement is false, we need to identify cases where P is true but Q is false, or when P is false but Q is true.

Option a) states that both P and Q are true. In this case, the statement "P implies Q" holds true because if P is true, then Q is true.

Option b) states that both P and Q are false. In this case, the statement "P implies Q" is considered true because the antecedent (P) is false.

Option c) states that P is true and Q is false. Under this condition, the statement "P implies Q" is false because when P is true, but Q is false, the implication does not hold.

Option d) states that P is false and Q is true. In this case, the statement "P implies Q" is true because the antecedent (P) is false.

Therefore, the conditions under which the statement "P implies Q" is false are a) P is true and Q is false, and d) P is false and Q is true.

The correct comparison of the shapes of the distributions would be D. Northview HS is symmetric, and Southdale HS is negatively skewed.

A symmetric shape is a shape that is the same on both sides of an axis of symmetry. The axis of symmetry can be a line or a point, and it divides the shape into two identical halves. This is how Northview HS looks.

On the other hand, a negatively skewed shape is a shape in which the values on the right side of the average (mean) are more spread out than the values on the left side of the average. This is how Southdale looks.

Answer: 15) 97

16) 16

17) 24

Step-by-step explanation:

15) (x-75) + (x-52)+ 293=360

x - 75 + x - 52 + 293 = 360

2x - 127 + 293 = 360

2x + 166 = 360

        2x  = 194           [Subtract 166 from both side]

          x  = 97             [Divide by 2 from both side]

16) (4x+15)+(5+6x)=180         The angle of a straight line is 180.

4x + 15 + 5 + 6x = 180

10x + 20 = 180

        10x = 160            [Subtract 20 from both side]

            x = 16               [Divide by 10 from both side]

17) (x+17)+(2x+1)= 90               These two angle combined equal to 90.

x + 17 + 2x + 1 = 90

3x + 18 = 90          

3x = 72                         [Subtract 18 from both side]

x = 24                           [Divide by 3 from both side]

Answer:

20÷(-10)=-2 is the answer

If 5x + 8 - 10 is simplified for some value of x, we can express it as 5x - 2. Now, if we substitute the same value of x into 10x + 16, we can simplify it to obtain the value of 10x + 16 based on the value of x given.

We can simplify 5x+8-10 to 5x-2.

If we know the value of x, we can substitute it into 5x-2 and evaluate the expression.

For example, if x = 3, then 5x-2 = 5(3)-2 = 13.

To find the value of 10x+16 for the same value of x, we can use the same value of x and substitute it into 10x+16.

Continuing the example from above, if x = 3, then 10x+16 = 10(3)+16 = 46.

Therefore, if 5x+8-10 is 5x-2 for some value of x, then 10x+16 is 10x+16 for the same value of x.

Profitability index is 1.387. Thus, the correct option is (c) 1.387.

The formula for calculating the profitability index is:

P.I = PV of Future Cash Flows / Initial Investment

Where,

P.I is the profitability index

PV is the present value of future cash flows

The initial investment in the project is $30 million. The cash flow at the end of the first year is $2.85 million.

The present value of cash flows can be calculated using the formula:

PV = CF / (1 + r)ⁿ

Where,

PV is the present value of cash flows

CF is the cash flow in the given period

r is the discount rate

n is the number of periods

For the first-year cash flow, n = 1, CF = $2.85 million, and r = 11%.

Substituting the values, we get:

PV = 2.85 / (1 + 0.11)¹ = $2.56 million

To calculate the present value of all future cash flows, we can use the formula:

PV = CF / (r - g)

Where,

PV is the present value of cash flows

CF is the cash flow in the given period

r is the discount rate

g is the constant growth rate

For the subsequent years, CF = $2.85 million, r = 11%, and g = 3.85%.

Substituting the values, we get:

PV = 2.85 / (0.11 - 0.0385) = $39.90 million

The total present value of cash flows is the sum of the present value of the first-year cash flow and the present value of all future cash flows.

PV of future cash flows = $39.90 million + $2.56 million = $42.46 million

Profitability index (P.I) = PV of future cash flows / Initial investment

= 42.46 / 30

= 1.387

Therefore, the correct option is (c) 1.387.

The inequality given by 69.50 + 5x ≤ 90 and the maximum gigabyte he can buy is 4.1.

What is inequality?

Inequalities are mathematical expressions where neither side is equal. In inequality, as opposed to equations, we compare two values. Less than (or less than or equal to), greater than (or greater than or equal to), or not equal to signs are used in place of the equal sign in between. Sometimes it can be about a "not equal to" relationship, where one thing is more than the other or less than. In mathematics, an inequality is a relationship that results in a non-equal comparison between two numbers or other mathematical expressions.

Let the number of gigabytes consumed be x,

The total cost per month will be 69.50 + 5x

accoding to the question the bill would not exceed $90.

So the inequality,

69.50 + 5x ≤ 90

Simplification for the maximum gigabyte he can buy,

5x ≤ 90 - 59.90

5x ≤ 20.5

x ≤ 4.1

Hence, the required inequality is given by 69.50 + 5x ≤ 90 and the maximum gigabyte he can buy is 4.1.

We notice the y-coordinates of point B and C are the same, indicating the line is horizontal. Its equation is y = 2.

The line perpendicular to the horizontal line y = 2 will be a vertical line. Its equation will be of the form ...

  x = c

where c is some constant.

We want this line to go through the point (4, 6), which has an x-coordinate of 4. That means the constant in the equation must be 4:

y(t) = 2e^(sin(t) + t) is the antiderivative of the function dy/dt = y cos(t) + y, and satisfies the initial condition y(0) = 2.

This is a first-order linear differential equation, which can be solved by the separation of variables. To do so, we can start by writing:

dy/dt = y cos(t) + y

We can divide both sides by y:

dy/dt / y = cos(t) + 1

Now, we can integrate both sides with respect to t, using the property that d(ln y)/dt = 1/y:

∫(dy/dt / y) dt = ∫(cos(t) + 1) dt

ln|y| = sin(t) + t + C

Where C is the constant of integration. To find its value, we can use the initial condition y(0) = 2:

ln|2| = sin(0) + 0 + C

C = ln|2|

Therefore, the solution of the initial value problem is:

y(t) = 2e^(sin(t) + t)

This is the antiderivative of the function dy/dt = y cos(t) + y and satisfies the initial condition y(0) = 2.

The property which guarantees that a twice-differentiable function has a relative minimum at x =c is the statement that f(c) = 0 and f''(c) > 0. Hence, option B is the correct answer.

Explanation:According to the second derivative test, if f''(c) > 0 and f(c) = 0, then the function f has a relative minimum at x = c. We're given that f is a function with two continuous derivatives. If f(c) = 0 and f(c) is less than zero, it is still possible for f to have a relative minimum, but only if the second derivative is negative and changes to positive at x = c.If f(0) = 0 and f(c) is less than zero, then we cannot conclude that f has a relative minimum at x = c since the second derivative is not guaranteed to be greater than zero at x = c. We can rule out f(x) > 0 for x since this is not a property that has anything to do with relative minima.

Step-by-step explanation:

The area of a triangle is base \(b\) times height \(h\) divided by \(2\). You can use the first triangle to solve for the height: \(9\cdot h/2=27\) means that \(h=6\). The larger triangle is proportional to the smaller one. In fact, it is \(1.\bar3\) times larger. This means that the height of the larger triangle is \(6\cdot1.\bar3=8\). Putting all of this together, you can then calculate the area: \(12\cdot8/2=48\).

The standard deviations of the four distributions are 5, 10, 15, and 20. The standard deviation increases as the data becomes more spread out.

The standard deviation measures the amount of variability or spread in a set of data. In this case, the four distributions have different amounts of spread, resulting in different standard deviations. The first distribution has the smallest spread, so its standard deviation is the smallest at 5. The second distribution has a larger spread than the first, resulting in a larger standard deviation of 10. The third distribution has an even larger spread, resulting in a standard deviation of 15. Finally, the fourth distribution has the largest spread, resulting in the largest standard deviation of 20. This makes sense because as the data becomes more spread out, there is more variability and the standard deviation increases.

The standard deviation increases as the data becomes more spread out. This is demonstrated in the four distributions with standard deviations of 5, 10, 15, and 20, which have increasing amounts of variability.
