The first step to change a fraction to a percent is to ...
A. Multiply the numerator by the denominator
B. Change the fraction to a decimal
C. Move the decimal point to the right
Answer:
a
Step-by-step explanation:
i am smart
Answer:
B
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 is to be conducted using a random sample of citizens in a town,
asking them if they support raising taxes to increase funding for the public school. Write the question in a way that is likely to bias the results toward more yes answers. Write the question in a way that is likely to bias the results toward more
no answers.
Answer:
yes i do
Step-by-step explanation:
A survey that asks readers to return the survey would result in voluntary-response bias
What is 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.

Find the circumference of the circle
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

Jim walks 6/7 of a mile every day. Russell walks 1/4 of a mile. How much farther does Jim work than Russell.
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

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:
1×1 = 12×2 = 43×3 = 94×4 = 165×5 = 256×6 = 3625 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:
1×1 = 12×2 = 43×3 = 94×4 = 165×5 = 256×6 = 3636 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:
1×1 = 12×2 = 43×3 = 94×4 = 1616 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.

The speed at which you can log into a website through a smartphone is an important quality characteristic of that website. In a recent test, the mean time to log into the JetBlue Airways website through a smartphone was 4.237 seconds. Suppose that the download time is normally distributed, with a standard deviation of 1.3 seconds. What is the probability that the download time is:
A. Less than 2 seconds?
B. Between 1.5 and 2.5 seconds
C. Above 1.8 seconds
D. 99% of the download times are slower (higher) than how many seconds?
E. 95% of the download times are between what two values, symmetrically distributed around the mean?
F. Suppose that the download times are uniformly distributed between 1 and 9 seconds. What are your answers to A through C?
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

enumerated articles

Answer:
B. 4/3
Step-by-step explanation:
The slope is rise over run or the change in y over the change in x. To find the slope count how many units y increases by then divide that by how many units x increases. In this graph y goes up by 4 and x increases by 3, so 4/3. Another way to find slope is the slope formula which is [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex], then plug in any two points and solve them.

The polynomial p is a function of x. The graph of p has four zeros at -4, -2/3, 0, and 9
Select all the expression that could represent p.
A
-3x(x + 4)(3x + 2)(x - 9)
B
3x(x – 4) (x + 3)(x +9)
с
3x(x + 4)(2x - 3)(x -9)
D
- x(x + 4) (x + })(x – 9)
E
-3x(x + 4)(3x + 2)(x - 9)2
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:
-4, -2/3, 0, and 9From 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]
