Answer:

0.24

Step-by-step explanation:

120 x 0.002 = 0.24

The correct answer is 0.24.

To find the product of 120 ×(0.002).

The zeroes are multiplied by the power of 10 which is 1/10 in particular.

For example.

The product of a whole number and a decimal number less than 1 will be greater than the whole number multiplied into. For this theorem to be proven. Let us state the mathematical expression into numbers such that

1.  N x 0.1 = N/0.1 < N

2.  1 x 0.5 = 0.5

3.  2 x 0.1 = 0.2

4.  100 x 0.55 = 55  

120 ×(0.002) = 0.24.

Therefore, the 120 × 0.002 = 0.24

Answer:

The mean of the sampling distribution of the proportion of downloaded books is 0.03 and the standard deviation is 0.0197.

Step-by-step explanation:

Central Limit Theorem

For a proportion p in a sample of size n, the sampling distribution of the sample proportion will be approximately normal with mean [tex]\mu = p[/tex] and standard deviation [tex]s = \sqrt{\frac{p(1-p)}{n}}[/tex]

3% of books borrowed from a library in a year are downloaded.

This means that [tex]p = 0.03[/tex]

SRS of 75 books.

This means that [tex]n = 75[/tex]

What are the mean and standard deviation of the sampling distribution of the proportion of downloaded books

By the Central Limit Theorem

Mean: [tex]\mu = p = 0.03[/tex]

Standard deviation: [tex]s = \sqrt{\frac{p(1-p)}{n}} = \sqrt{\frac{0.03*0.97}{75}} = 0.0197[/tex]

The mean of the sampling distribution of the proportion of downloaded books is 0.03 and the standard deviation is 0.0197.

Answer:

[tex]A = (\frac{80}{3},9)[/tex]

[tex]B = (5,2.5)[/tex]

The slope is 0.3

Step-by-step explanation:

Given

[tex]y = 0.3x + 1[/tex]

[tex]A = (-,9)[/tex]

[tex]B = (5,-)[/tex]

Required:

Fill in the gap and calculate the slope

In [tex]A = (-,9)[/tex]

[tex]y = 9[/tex] and x is ??

Substitute 9 for y in [tex]y = 0.3x + 1[/tex]

[tex]9 = 0.3x + 1[/tex]

Collect Like Terms

[tex]0.3x = 9 - 1[/tex]

[tex]0.3x = 8[/tex]

[tex]x = \frac{8}{0.3}[/tex]

[tex]x = \frac{80}{3}[/tex]

So:

[tex]A = (-,9)[/tex]

[tex]A = (\frac{80}{3},9)[/tex]

In [tex]B = (5,-)[/tex]

[tex]x = 5[/tex] and y is ??

Substitute 5 for x in [tex]y = 0.3x + 1[/tex]

[tex]y = 0.3 * 5 + 1[/tex]

[tex]y = 1.5 + 1[/tex]

[tex]y = 2.5[/tex]

So:

[tex]B = (5,-)[/tex]

[tex]B = (5,2.5)[/tex]

Calculating the slope (m)

[tex]m = \frac{y_2 - y_1}{x_2 - x_1}[/tex]

[tex]m = \frac{2.5-9}{5 - \frac{80}{3}}[/tex]

[tex]m = \frac{-6.5}{\frac{15- 80}{3}}[/tex]

[tex]m = \frac{-6.5}{\frac{-65}{3}}[/tex]

[tex]m = \frac{-6.5*3}{-65}[/tex]

[tex]m = \frac{-19.5}{-65}[/tex]

[tex]m = 0.3[/tex]

Answer:

c p = -86.4

aww man I got to explain too I used this app called math - way they will explain it

Answer:

1.68 Meters

Step-by-step explanation:

Hello I think I can help with this.

Well basically the way it is represented as a fraction is a portion of a whole like a percent :

For example : 21%

So basically we just need to turn this into a decimal and then add to find how long the books would be together.

How I would go about doing this is first looking at the 21/100 and remember that in decimals 1.00 is a whole just like the 100. So in this case the 100 in 21/100 would be 1.00.

So knowing this, we can take the 21 in 21/100 and say that 0.21/1.00 is equal to 21/100 because the 21 is representing how much of a meter the books are while 100 is the whole meter.

Now, we know we have eight books and each are .21 long. So we can do :

.21 x 8

=

1.68

While this is the answer we can write it in two ways. Either in fraction form like it started or in decimal form which I think is how they want you to write the answer.

For fraction :

168/100 Meters

We can simplify this :

1 68/100 Meters

EDIT :

We can simplify this even more :

Lets divide both sides by 2 :

34/50

AND we can do it again :

So divide by 2 on both sides :

17/25

And don't forget to add the 1 back into it :

1 17/25

And for the decimal form it is just what we found already :

1.68 Meters

I hope this helps!

Answer:

The vertex of f(x) is at (-5,-10).

The function g(x) is decreasing at a rate of 5%.

The zeros of h(x) are at x = -3 and x = 1.

Step-by-step explanation:

Vertex of a quadratic function:

Suppose we have a quadratic function in the following format:

[tex]f(x) = ax^{2} + bx + c[/tex]

It's vertex is the point [tex](x_{v}, f(x_{v})[/tex]

In which

[tex]x_{v} = -\frac{b}{2a}[/tex]

If a<0, the vertex is a maximum point, that is, the maximum value happens at [tex]x_{v}[/tex], and it's value is [tex]f(x_{v})[/tex]

Decaying exponential function:

A decaying exponential function has the following format:

[tex]A(x) = A(0)(1-r)^{x}[/tex]

In which A(0) is the initial quantity and r is the decay rate.

Zeros of a function:

Given a polynomial f(x), this polynomial has roots [tex]x_{1}, x_{2}, x_{n}[/tex] such that it can be written as: [tex]a(x - x_{1})*(x - x_{2})*...*(x-x_n)[/tex], in which a is the leading coefficient.

Vertex of f:

The function f is given by:

[tex]3(x+5)^2 - 10[/tex]

Expanding the calculations to place at the correct format:

[tex]3(x+5)^2 - 10 = 3(x^2 + 10x + 25) - 10 = 3x^2 + 30x + 75 - 10 = 3x^2 + 30x + 65[/tex]

Which means that

[tex]a = 3, b = 30, c = 65[/tex]

The x-value of the vertex is:

[tex]x_{v} = -\frac{30}{2*3} = -5[/tex]

The y-value of the vertex is:

[tex]f(-5) = 3(-5+5)^2 - 10 = -10[/tex]

The vertex of f(x) is at (-5,-10).

Decreasing rate of g(x).

We have that:

1 - r = 0.95

So

r = 1 - 0.95 = 0.05

Which means that the decreasing rate is of 5%.

The zeros of h(x) are

The zeros are

x + 3 = 0 -> x = -3

x - 1 = 0 -> x = 1

So

The zeros of h(x) are at x = -3 and x = 1.
