Answer: 16
Step-by-step explanation:
In a student survey, fifty-two part-time students were asked how many courses they were taking this term. The (incomplete) results are shown below: Please round your answer to 4 decimal places for the Relative Frequency if possible. # of Courses Frequency Relative Frequency Cumulative Frequency 1 20 Correct .3846 Correct 20 2 19 0.3654 39 Correct 3 13 0.25 52 What percent of students take exactly one courses? 51.61 Incorrect%
Answer:
The percentage of students taking exactly one courses is 38.46%.
Step-by-step explanation:
The frequency distribution table provided for the number of courses taken by part-time students is as follows:
# of Courses Frequency Relative Cumulative
Frequency Frequency
________________________________________________
1 20 0.3846 20
2 19 0.3654 39
3 13 0.2500 52
TOTAL 52 1.0000
The relative frequency is actually the probability or chance of the particular class or category of a frequency distribution.
The probability of students taking exactly one courses is 0.3846.
Then the percentage of students taking exactly one courses is:
0.3846 × 100% = 38.46%
Thus, the percentage of students taking exactly one courses is 38.46%.

Find the exact trigonometric ratios for the angle x whose radian measure is given. (If an answer is undefined, enter UNDEFINED.) −7π
Answer:
sin(x) = tan(x) = 0
cos(x) = sec(x) = -1
cot(x) = csc(x) = UNDEFINED
Step-by-step explanation:
An angle of -7π is co-terminal with an angle of π (or 180°). Its trig ratios are ...
sin(x) = tan(x) = 0
cos(x) = sec(x) = -1
cot(x) = csc(x) = UNDEFINED

What are some methods for finding the distance between points A and B? You can use the pen tool to explore different options on the number line?
Answer:
Ok, the straightforward thing you can do, when you have a number line like in this situation, you can just "count" the number of units that are between A and B.
Now, a more correct way:
First, A is located at the value -3, then we can write:
A = -3.
And B is located at the value 5, then:
B = 5.
Now, the distance between A and B is equivalent to the difference between A and B:
D = B - A = 5 - (-3) = 8
The distance between A and B is 8 units.

the surface area of a sphere whose radius is 0.5 cm is
Answer: The answer is 3.14 (also known as π)
Step-by-step explanation: The formula for the surface area of a sphere is:
A = 4πr^2
A = 4π (0.5)^2
A = 4π (0.25)
A = (4 x 0.25) π
A = 1π
A = π or A = 3.14

What is the base of the rate is 16.1% and the portion is 454
The rate is 16.1% and the base is the final portion with the rate added on to it.
Chance the percentage into a decimal.
16.1% / 100 = 0.161
Multiply.
454 * 0.161 = 73.094
Add.
454 + 73.094 = 527.094 or 527.09
Therefore, the final base is roughly 527.09

14 + (-12)-8-5
FAST PLEASE ALSO PLEASE SHOW THE STEPS!!!
Answer:
-11
Step-by-step explanation:
start with PEMDAS (parenthesis, exponents, multiplication, division, addition, subtraction)
so you would first start with 14 + (-12) so the + and - become a negative so it becomes 14 - 12 which is 2
so then do -8-5 which is -13
so then you combine them and get 2-13 which is -11

Polynomial Roots Calculator is a set of methods aimed at finding values of a for which F(a)=0
Rational Roots Test is one of the above mentioned tools. It would only find Rational Roots that is numbers a which can be expressed as the quotient of two integers
The Rational Root Theorem states that if a polynomial zeroes for a rational number P/Q then P is a factor of the Trailing Constant and Q is a factor of the Leading Coefficient
In this case, the Leading Coefficient is 7 and the Trailing Constant is 1.
The factor(s) are:
of the Leading Coefficient : 1,7
of the Trailing Constant : 1

What percentage of the data in a standard normal distribution lies between x = .09 and x = 1.2?
Answer:
The percentage is [tex]P(0.09 < \mu < 1.2 ) = 34.9\%[/tex]
Step-by-step explanation:
From the question we are told that
The random number is [tex]x_1 = 0.09 \ and \ x_2 = 1.2[/tex]
Generally the mean of standard normal distribution is [tex]\mu = 0[/tex]
The standard deviation of a standard normal distribution is [tex]\sigma = 1[/tex]
The percentage of the data in a standard normal distribution lies between
[tex]x_1 = 0.09 \ and \ x_2 = 1.2[/tex] is mathematically represented as
[tex]P(x_1 < \mu < x_2 ) = P(\frac{x_1 - \mu}{\sigma } <\frac{X - \mu}{\sigma } < \frac{x_2 - \mu}{\sigma } )[/tex]
[tex]P(0.09 < \mu < 1.2 ) = P(\frac{0.09 - 0}{1 } <\frac{X - \mu}{\sigma } < \frac{1.2 - 0}{1 } )[/tex]
[tex]P(0.09 < \mu < 1.2 ) = P(0.09 <\frac{X - \mu}{\sigma } < 1.2 )[/tex]
The [tex]\frac{X - \mu}{\sigma } = Z(The \ standardized \ value \ of \ X )[/tex]
[tex]P(0.09 < \mu < 1.2 ) = P(0.09 <Z < 1.2 )[/tex]
[tex]P(0.09 < \mu < 1.2 ) = P (Z < 1.2 )- P( Z<0.09)[/tex]
From the z-table
[tex]P (Z < 1.2 )= 0.88493[/tex]
[tex]P( Z<0.09) = 0.53586[/tex]
So
[tex]P(0.09 < \mu < 1.2 ) = 0.88493 - 0.53586[/tex]
[tex]P(0.09 < \mu < 1.2 ) = 0.349[/tex]
Hence the percentage is
[tex]P(0.09 < \mu < 1.2 ) = 34.9\%[/tex]

solve the equation 6 over x + 1 over 2 equals to 2
Answer:
x = 4
Step-by-step explanation:
6/x + 1/2 = 2
x(6/x + 1/2) = 2*x
x*6/x + x*1/2 = 2x
6 + x/2 = 2x
6 = 2x - x/2
6 = 4x/2 - x/2
6 = 3x/2
6*2/3 = x
12/3 = x
x = 4
probe:
6/4 + 1/2 = 2
3/2 + 1/2 = 4/2

a)250cm =______ mm.
b)5000m = ____ km.
c) 200km =______cm.
Answer:
a = 2500mm
b = 5km
c = 2e+7
Step-by-step explanation:
Answer:
a)
1cm = 10mm
250cm = 250*10 = 2500mm
b)
1km = 1000m
5000m = 5000/1000 = 5km
c)
1km = 1000m
1m = 100cm
1km = 1000*100 = 100000cm
200km = 200*100000 = 20000000cm
