Answer:

A.) 0.0426

B) 0.073121

C.) 0.96958

D.) 1.2 seconds

E.) 1.689 < x < 6.785

Step-by-step explanation:

Given a normal distribution :

Mean download time (m) = 4.237 seconds

Standard deviation (s) = 1.3 seconds

A.) Probability that download time is less than 2 seconds :

P(x < 2)

Obtain standardized score (Z) :

Z = (x - m) / s

Z = (2 - 4.237) / 1.3

Z = −1.720769

P(Z < - 1.7208) = 0.0426 (Z probability calculator)

B.) Between 1.5 and 2.5 seconds :

1.5 < z < 2.5

((x - m) / s) < z <((x - m) / s)

((1.5 - 4.237) / 1.3) < z < ((2.5 - 4.237) / 1.3)

−2.105384 < z < −1.336153

P(Z < - 2.10538) = 0.017629

P(Z −1.336153) = 0.09075

0.09075 - 0.017629 = 0.073121

C.) Above 1.8 seconds

P(x > 1.8)

Obtain standardized score (Z) :

Z = (x - m) / s

Z = (1.8 - 4.237) / 1.3

Z = −1.874615

P(Z > −1.874615) = 0.96958 (Z probability calculator)

D.) 99% of the download times are slower (higher) than how many seconds?

P(Z > x) = 99% = 0.99

Z value corresponds to -2.326

Z = (x - m) / s

-2.326 = (x - 4.237) / 1.3

-2.326 * 1.3 = x - 4.237

−3.0238 = x - 4.237

−3.0238 + 4.237 = x

x = 1.2132

x = 1.2 seconds

E. 95% of the download times are between what two values, symmetrically distributed around the mean?

For symmetric distribution around the mean ;

P(-Z<x<Z) = 0.95

Corresponds to a z value of 1.96

-1.96 * 1.3 = x - 4.237

-2.548 = x - 4.237

x = - 2.548 + 4.237

x = 1.689

1.96 * 1.3 = x - 4.237

2.548 = x - 4.237

x = 2.548 + 4.237

x = 6.785

1.689 < x < 6.785

sum of internal angles of any triangle = 180 degrees

sum of an exterior angle and an interior angle = 180 degrees

Answer:

[tex]a=180-2.50d[/tex]

Step-by-step explanation:

If Penny starts with a balance of $180, and [tex]a[/tex] represents the account left in her account after [tex]d[/tex] days. we can start modeling an incomplete equation:

[tex]a=180[/tex]

We are then told that she spends $2.50 each ([tex]d[/tex]) day. This can be represented as:

[tex]2.50d[/tex]

Let's now include the expression into the incomplete equation. Remember that since she is spending, the [tex]2.50d[/tex] will be subtracted from her balance of $180:

[tex]a=180-2.50d[/tex]

Answer:

31.4 cm

Step-by-step explanation:

it says [tex]c =\pi d[/tex]

d stands for the diameter and to find d, just add the radius by itself.

So to find d, you would add 5 + 5 which would be 10 and multiply 3.14 which stands for pi. And the answer you would get is 31.4

A ≈ 380.13in²

Or A= 379.94in²

Step-by-step explanation:

Formula for area:

A = π r²

A=π ·11² ≈ 380.13in²

If π is used as 3.14 then

A=3.14·11² = 379.94

Answer:

n > -4

Step-by-step explanation:

1) Combine like terms.

13 + n > 9

2) Isolate n. (subtract 13 from both sides)

n > -4

The only expression of that can represent polynomial p as a function on a graph having four zeros at -4, -2/3, 0, and 9 is: A. [tex]\mathbf{-3x(x + 4)(3x + 2)(x - 9)}[/tex]

Given the four zeros of the graph of p are at:

From the options given, the expression in option A will represent a function of a polynomial p with zeros at -4, -2/3, 0, and 9.

Here's why:

[tex]-3x(x + 4)(3x + 2)(x - 9)[/tex] (option A)

Therefore are four factors in the polynomial above which are:

[tex]3x\\\\(x + 4)\\\\(2x - 3), $ and\\\\(x -9)[/tex]

The zeros of polynomial p will be the following:

[tex]3x = 0\\\\x = \frac{0}{3} \\\\\mathbf{x = 0}[/tex]

[tex](x + 4) = 0\\\\\mathbf{x = -4}[/tex]

[tex](3x + 2) = 0\\\\3x = -2\\\\\mathbf{x =-\frac{2}{3}}[/tex]

[tex](x -9) = 0\\\\\mathbf{x = 9}[/tex]

Therefore, the only expression of that can represent polynomial p as a function on a graph having four zeros at -4, -2/3, 0, and 9 is: A. [tex]\mathbf{-3x(x + 4)(3x + 2)(x - 9)}[/tex]

Answer:

Tanto Pedro como Jorge deberán pintar 1/4 de la habitación cada uno.

Step-by-step explanation:

Dado que el cuarto entero es igual a 1, y que Arturo por ser el mayor de los hermanos tiene que pintar 1/2 de él, la parte que falta pintar es igual a 1/2 restante.

De ese 1/2, los hermanos menores, Pedro y Jorge, deben pintar dicha fracción en partes iguales. Por lo tanto, dado que (1/2) / 2 es igual a 1/4, la fracción que tanto Pedro como Jorge deberán pintar es de 1/4 de la habitación.

Answer:

Jim walked 17/28 for miles than Russel

Step-by-step explanation:

First you turn 6/7 and 1/4 to have the same denominators. In that case you find the least common multiple which is 28.

7: 7, 14, 21, 28

4: 4, 8, 12, 16, 20, 24, 28

Next you multiply the top and the bottom of your fraction my the factor you used to get 28 for your denominator

6/7 x 4/4 = 24/28

1/4 x 7/7 = 7/28

Lastly, you subtract the products you got.

24/28 - 7/28 = 17/28

To change a fraction into a percent you need to turn it into a decimal so you can then move the decimal place 2 times to the right. It looks something like this:

1/2 ------>  0.5 -----------> 50%

To change a percent into a decimal move the decimal place twice to the left. Like so:

85.5% ------> 0.855

A survey that asks readers to return the survey would result in voluntary-response bias

When the response to a survey by a reader is not influenced by the author or the questioner of the survey the response sent by the reader is going to be a voluntary response.

In a voluntary response, the response is void of external influence therefore the reader gives his/her honest opinion without the external/Questioner's bias

Allowing your sample to self-select skews your data and prevents you from getting accurate results that are representative of your entire population, which is what is meant by voluntary response bias.

Hence we can conclude that a survey that asks readers to return the survey would result in voluntary response bias.

Answer:

a in table → b on number line

b in table → c on number line

c in table → a on number line

Step-by-step explanation:

Here, we see the points are square roots. A square root of a number is a value, that when multiplied by itself, gives the number. For example, 4 × 4 = 16, so the square root of 16 is 4.

We can apply this logic easily by simplifying the square root, or multiplying integers with each other (aka "squaring" the integers) and seeing which result is closest to the value inside the square root.

Simplifying the square root won't help here, if we don't know basic values such as √3 or √2. So, we can just multiply an integer with itself and see if that value is closer to the value inside the square root.

For point a, we see the number inside the root is 27. We can start multiplying:

25 is the closest value to 27 here. So, we know the point is somewhere around 5, and since 27 is slightly larger than 25, the point is slightly larger than 5. So, point a in the table is most likely point b on the number line.

For point b, we see the number inside the root is 32. We can start multiplying:

36 is the closest value to 32 here. So, we know the point is somewhere around 6, and since 32 is smaller than 36, the point is lesser than 6. So, point b in the table is most likely point c on the number line.

For point c, we see the number inside the root is 16. We can start multiplying:

16 is right on the dot! That means that the square root of 16 is 4, which leaves us with point a on the number line.
