The two plots compare the top 25 home run hitters in 2007 with those in 2008. Which choice is NOT true?

Answer:

The age distribution of a population is shown.

a. The probability that a person chosen at random is at least 15 years old is 14%

b. The probability that a person chosen at random is 25 - 44 years old is 26%

The probability that a person chosen at random is at least 15 years is 80%

The probability that a person chosen at random is 25 - 44 years old is 26%

Probability determines how likely it is that a stated event would occur. This probability lies between 0 and 1.

The probability that a person chosen at random is at least 15 years = sum of percentages of people at least 15 years old : 14 + 13 + 13 + 15 + 12 + 13 = 80%

The probability that a person chosen at random is 25 - 44 years old : 13% + 13% = 26%

The Perimeter of the given figure is 20.56 feet and the area is 25.12 + 12.56 = 37.68 square feet (rounded to two decimal places).

The perimeter and area of the figure is to be determined with the given values. The figure is shown below,In the given figure, a partial circle with center A has a radius of 4 feet.

It can be observed that the given figure is not a circle, but a semi-circle and a quarter of a circle.We know that,For a circle of radius r,Perimeter = 2πrArea = πr²For the semi-circle of radius 4 feet

,Perimeter = πr + 2r= π(4) + 2(4) = 4π + 8 feet= (4 x 3.14) + 8= 12.56 + 8= 20.56 feet (rounded to two decimal places)Area = 1/2 πr²= 1/2 π(4)²= 1/2 x 3.14 x 16= 25.12 square feet (rounded to two decimal places)For the quarter of a circle of radius 4 feet, Perimeter = πr/2 + 2r= π(4)/2 + 2(4) = 2π + 8 feet= 2(3.14) + 8= 6.28 + 8= 14.28 feet (rounded to two decimal places)

Area = 1/4 πr²= 1/4 π(4)²= 1/4 x 3.14 x 16= 12.56 square feet (rounded to two decimal places)

Therefore, the perimeter of the given figure is 20.56 feet and the area is 25.12 + 12.56 = 37.68 square feet (rounded to two decimal places).

Answer:

D) x<0 or x>3

Step-by-step explanation:

x(x-3)>0

either x>0 and x-3>0      .... positive-positive=positive   so x>3

or x<0 and x-3<0    ..... negative-negative=positive  so x<0

if x=0 then x(x-3)=0

The solution to the inequality is x < 0 or x > 3

Inequalities are the mathematical expressions in which both sides are not equal. In inequality, unlike in equations, we compare two values. The equal sign in between is replaced by less than (or less than or equal to), greater than (or greater than or equal to), or not equal to sign.

In an inequality, the two expressions are not necessarily equal which is indicated by the symbols: >, <, ≤ or ≥.

Given data ,

Let the inequality equation be represented as A

Now , the value of A is

Substituting the values in the equation , we get

To solve the inequality x(x - 3) > 0, we can use a sign chart.

First, we can find the critical points of the inequality, which are the values of x that make the expression x(x - 3) equal to zero. These values are x = 0 and x = 3.

Then, we can create a sign chart with these critical points and test intervals between them to determine the sign of the expression x(x - 3) in each interval.

Interval Test Value x(x - 3)

x < 0   -1                Positive

0 < x < 3    1                  Negative

x > 3    4                Positive

From the sign chart, we see that x(x - 3) is positive when x < 0 and when x > 3, and negative when 0 < x < 3.

Hence , the solution to the inequality x(x - 3) > 0 is x < 0 or x > 3

The height the anchor begins to drop is 17.5 m

Since a Naval Carrier dropped anchor off the coast. The massive anchor drops at 3.5 m/s and will be 52.5 meters under the surface of the water after 20 seconds.

Let

The total height the anchor drops is thus H = h + h'

Now, the total height the anchor drops H = vt where

So, equating both equations, we have

vt = h + h'

Making h subject of the formula, we have that

h = vt - h'

Given that

Substituting the values of the variables into the equation, we have that

h = vt - h'

h = 3.5 m/s × 20 s - 52.5 m

h = 70 m - 52.5 m

h = 17.5 m

So, the anchor drops 17.5 m

Answer: \(-\frac{5}{7}\)

Step-by-step explanation:

To find the slope of the line, you want to use the formula \(m=\frac{y_2-y_1}{x_2-x_1}\).

\(m=\frac{-3-2}{3-(-4)} =\frac{-5}{7}\)

Now we know the slope is \(-\frac{5}{7}\).

Let's use x to represent the cost of one orange and y to represent the cost of one lemon. We can then set up a system of two equations:16x + 13y = 9.29 19x + 6y = 9.05 These equations represent the total cost of buying a certain number of oranges and lemons in two different scenarios.

To understand why we need two equations, let's consider the first equation: 16x + 13y = 9.29

This equation tells us that if we buy 16 oranges and 13 lemons, the total cost will be $9.29. But we don't know the individual prices of oranges and lemons yet. That's where the second equation comes in: 19x + 6y = 9.05

This equation tells us that if we buy 19 oranges and 6 lemons, the total cost will be $9.05. Again, we don't know the individual prices yet.

By setting up a system of equations, we can solve for x and y, which represent the prices of oranges and lemons, respectively.

One way to solve this system is by elimination. We can multiply the first equation by 19 and the second equation by -16, which will allow us to eliminate y:

304x + 247y = 176.51
-304x - 96y = -144.8

Adding these two equations together gives: 151y = 31.71
Dividing both sides by 151, we get: y = 0.21
Now we can substitute this value of y into one of the original equations to solve for x. Let's use the first equation:
16x + 13(0.21) = 9.29
16x + 2.73 = 9.29
16x = 6.56
x = 0.41

So the cost of one orange is $0.41 and the cost of one lemon is $0.21.

Step-by-step explanation:

Assume that you mean if c÷d is positive or negative when c > 0 and d < 0

d < 0 means that d is negative

positive divides negative is always negative.

Thus, c÷d is negative when c > 0 and d < 0

The function f(x) = ln(2 + sin(x))) is concave up for the range of x [0,2].

To discover the interval(s) on which f(x) = ln(2 + sin(x)) is concave up, compute the function's second derivative and check its sign.

To begin, compute the first derivative of f(x) with respect to x:

(1 / (2 + sin(x)) = f'(x)cos(x)

The second derivative of f(x) can therefore be found by taking the derivative of f'(x) with regard to x:

f''(x) = -(1/(2 + sin(x))(-sin(x)) cos2(x) + (1/(2 + sin(x))

When we simplify f''(x), we get:

f''(x) = -1/(2 + sin(x))²)sin(x)(sin(x)-2)

To discover the interval(s) where f(x) is concave up, we must first locate the interval(s) where f''(x) is positive. Because sin(x) might vary from -1 to 1, we must solve the inequality:

-(1/(2 + 1))^2(-1)(-1-2)≤f''(x)≤-(1 / (2 - 1))²(1) (1-2)

When we simplify this inequality, we get:

1/9 ≤ f''(x) ≤ -1/4

So, f is never negative at 0 ≤ x ≤ 2, so f is concave up in the range 0 ≤ x ≤ 2.

The rpm of the 10-tooth sprocket when driven by the same chain that drives a 20-tooth sprocket at 10 rpm will be 20 rpm.

The speed of a sprocket is directly proportional to the number of teeth on it. Therefore, if a 20-tooth sprocket is turning at 10 rpm, it means that it covers 200 teeth in one minute. When the same chain drives a 10-tooth sprocket, it means that the sprocket will cover half the distance or 100 teeth in one minute.
Therefore, the rpm of the 10-tooth sprocket will be double that of the 20-tooth sprocket, and it will turn at 20 rpm. This calculation is based on the fact that the chain is of the same length and is connected to the same motor, which provides the same power output. Hence, the speed of the sprocket is determined by the number of teeth on it.
In conclusion, the rpm of the 10-tooth sprocket when driven by the same chain that drives a 20-tooth sprocket at 10 rpm will be 20 rpm.

According to the information provided,

The point of discontinuity of rational functions is at x=7.

When a rational function has a point of discontinuity, it generally occurs when,

The required, expression -7 + 24i with the form a + bi, we can see that the value of b is 24.

To find the value of b in the expression (3 + 4i)^2, we can simply expand the expression and identify the coefficient of the imaginary part.

(3 + 4i)² = (3 + 4i)(3 + 4i)

Using the FOIL method, we can multiply the terms:

= 3 * 3 + 3 * 4i + 4i * 3 + 4i * 4i

= 9 + 12i + 12i + 16i²

Since i² is defined as -1, we can substitute it:

= 9 + 12i + 12i - 16

= -7 + 24i
