Answer:

maybe the first one sorry if its wrong

Step-by-step explanation:

Step-by-step explanation:

%decrease = 1800 - 500 * 100

__________

1800

%decrease = 1300/1800 * 100

% decrease = 72.2%

Average attendance in 2003 = 1800

Average attendance in 2004 = 500

Decrease in attendance = 1800 - 500 = 1300

Decrease percentage in attendance

[tex] = \frac{1300}{1800} \times 100[/tex]

[tex] = \frac{13}{18} \times 100[/tex]

[tex] = \frac{13}{9} \times 50[/tex]

=72.22

Answer:

x=19.5 or 19 1/2

Step-by-step explanation:

To find what x is we need to get x on one side of the equal sign with the numbers on the other side, but first, we need to add the same variables and numbers together.

Add:

4x+12=90

Move the 12 to the other side by subtracting 12 on both sides (You use the inverse of what you want to move to the other side)

4x+12-12=90-12

4x=78

Divide:

You need to divide 4x by 4 (Since 4x is the same thing as 4*x you need the inverse of multiplication to reverse it which is division)

x=19.5 or 19 1/2 (Since 1/2 is the same thing as 0.5)

Answer:

[tex]8 \le f(4) - f(2) \le 10[/tex]

Step-by-step explanation:

Given

[tex]4 \le f'(x) \le 5[/tex]

Required

Determine the minimum and maximum value of f(4) - f(2)

This question will be answered using the following mean value theorem.

[tex]f'(x) = \frac{f(b) - f(a)}{b - a}[/tex]

In this case: [tex]b = 4[/tex] and [tex]a = 2[/tex]

So, we have:

[tex]f'(x) = \frac{f(4) - f(2)}{4 - 2}[/tex]

[tex]f'(x) = \frac{f(4) - f(2)}{2}[/tex]

Make f(4) - f(2), the subject:

[tex]f(4) -f(2) = 2 * f'(x)[/tex]

From the given range: [tex]4 \le f'(x) \le 5[/tex]

We have that; f'(x) is at minimum at 4

So, the minimum of f(4) - f(2) is:

[tex]f(4) -f(2) = 2 * 4[/tex]

[tex]f(4) -f(2) = 8[/tex]

We have that; f'(x) is at maximum at 5

So, the maximum of f(4) - f(2) is:

[tex]f(4) - f(2) = 2 * 5[/tex]

[tex]f(4) - f(2) = 10[/tex]

Hence, the minimum and maximum values can be expressed as:

[tex]8 \le f(4) - f(2) \le 10[/tex]

Find the slope m.

Use the point-slope formula.

Answer:

1. E. All of the above

2. A. Confirmation bias

Step-by-step explanation:

Data is collected for different reasons by various individuals and groups. Collecting data consumes time and can be very costly. In most cases, human error can lead to error in the dataset collected and bias in the information given.

Hypothesis testing is the theory or process of comparing a hypothesis with a null hypothesis. The null hypothesis is rejected only if the probability of the fall below the specified level of significance, thereby accepting the hypothesis which is said to be in the level of significance.

Answer:

y = -2x - 3

Step-by-step explanation:

First, find slope (m) of the line using two points (0, -3) and (1, -5):

[tex] slope (m) = \frac{y_2 - y_1}{x_2 - x_1} = \frac{-5 -(-3)}{1 - 0} = \frac{-2}{1} = -2 [/tex]

The line intercepts the y-axis at y = -3. Therefore the y-intercept (b) of the line = -3.

To write the equation that represents the line, substitute m = -2, and b = -3 into y = mx + b.

Thus:

y = -2x + (-3)

y = -2x - 3

I believe that her goal is 20 pages because 75% of 20 is 15.

Step-by-step explanation:

Answer:

The zeros are:

[tex]x =4, x=2, x = 5[/tex]

Hence, option (B) is true.

Step-by-step explanation:

Given the expression

[tex]h\left(x\right)=\left(x-4\right)^2\left(x^2-7x+\:10\right)[/tex]

Let us determine the zeros of the function by putting h(x) = 0 and solving the expression

[tex]0=\left(x-4\right)^2\left(x^2-7x+10\right)[/tex]

switch sides

[tex]\left(x-4\right)^2\left(x^2-7x+10\right)=0[/tex]

as

[tex]x^2-7x+\:10=\left(x-2\right)\left(x-5\right)[/tex]

so

[tex]\left(x-4\right)^2\left(x-2\right)\left(x-5\right)=0[/tex]

Using the zero factor principle

so

[tex]x-4=0\quad \mathrm{or}\quad \:x-2=0\quad \mathrm{or}\quad \:x-5=0[/tex]

[tex]x =4, x=2, x = 5[/tex]

Thus, the zeros are:

[tex]x =4, x=2, x = 5[/tex]

It is clear that there are three zeros and all the zeros are distinct real numbers.

Therefore,

Hence, option (B) is true.
