I toss a coin 20 times. comes up "Heads" 7 times. What is the 1 point
relative frequency of getting a "Head"?
Someone help please I have to finish this quickly—
Answer in fraction form = 7/20
Answer in decimal form = 0.35
Answer in percent form = 35%
These are three ways to say the same thing.
======================================================
Explanation:
To get the relative frequency, you divide the number of times heads comes up out of the number of tosses total. Reduce the fraction as much as possible. In this case, 7 and 20 have no factors (other than 1) in common. So the fraction 7/20 cannot be reduced further.
The fraction 7/20 converts to the decimal form 0.35 after using a calculator or long division.
0.35 converts to 35% after moving the decimal over to the right two spots.
Water makes up 3.4 of a person's weight. If a student weighs 100 lbs., how much of his weigh is water?
Answer:
75
Step-by-step explanation:
To determine how much of a persons weight is water, multiply 3/4 by their weight.
weight of water = weight x 3/4
100 x 3/4 0r 100 x 0.75 ( same thing)
75
The student weighs 75 lbs underwater
P.S it's not 3.4 it's 3/4 = 75% of our body is made up of water.
Write
73/50
as a decimal.
Answer:
1.46
Step-by-step explanation:
We know that
[tex]\frac{73}{50}[/tex]
is the same as
73÷50
Then using
Long Division for 73 divided by 50
and rounding to a Max of 3 Decimal Places gives us
=1.46
have a wonderful day
A clerk mixes a 15 pound a 15 pound bag of nuts for a customer. peanuts cost $ 5.50 5.50 per pound pound amd cashews cost $ 7.60 7.60 per pound . Pound . the total cost comes to $ 75.50 write a system of equations to find how many pounds of peanuts and how many pounds of cashew are in the bag
Answer:
[tex]x+y= 15---------------------1\\\\5.5x+7.6y= 75.5----------------2[/tex]
Step-by-step explanation:
Given data
let the number of peanuts be x
and the number of cashew be y
so
x+y= 15---------------------1
and
5.5x+7.6y= 75.5----------------2
Hence the system of equation is given as
[tex]x+y= 15---------------------1\\\\5.5x+7.6y= 75.5----------------2[/tex]
Which sets of ordered pairs show equivalent ratios? (1, 2), (2, 3), (4, 7) (2, 2), (4, 4), (6, 6) (3, 1), (4, 1), (5, 1) (4, 1), (8, 2), (12, 3) (2, 1), (4, 3), (5, 4)
Given:
The different sets of ordered pairs in the options.
To find:
The sets of ordered pairs that show equivalent ratios
Solution:
The set of ordered pairs show equivalent ratios, if
[tex]\dfrac{y}{x}=k[/tex]
Where, k is a constant.
For option 1,
(1, 2), (2, 3), (4, 7)
[tex]\dfrac{2}{1}\neq \dfrac{3}{2}[/tex]
For option 2,
(2, 2), (4, 4), (6, 6)
[tex]\dfrac{2}{2}=\dfrac{4}{4}=\dfrac{6}{6}=1=k[/tex]
The set of ordered pairs (2, 2), (4, 4), (6, 6) show equivalent ratios.
For option 3,
(3, 1), (4, 1), (5, 1)
[tex]\dfrac{1}{3}\neq \dfrac{1}{4}[/tex]
For option 4,
(4, 1), (8, 2), (12, 3)
[tex]\dfrac{1}{4}=\dfrac{2}{8}=\dfrac{3}{12}=k[/tex]
The set of ordered pairs (4, 1), (8, 2), (12, 3) show equivalent ratios.
For option 5,
(2, 1), (4, 3), (5, 4)
[tex]\dfrac{1}{2}\neq \dfrac{3}{4}[/tex]
So, sets of ordered pairs in options 1, 3 and 5 does not show equivalent ratios.
Therefore, the correct options are 2 and 4.

how many units apart are (3.1,-1) and (4.1,-1)
Answer:
The points are 1 unit apart.
Step-by-step explanation:
Given points are:
(3.1,-1) and (4.1,-1)
Distance formula is given by;
Distance between points = [tex]\sqrt{(x_2-x_1)^2+(y_2-y_1)^2[/tex]
Where,
[tex](x_1,y_1)[/tex] = Coordinates of first point
[tex](x_2,y_2)[/tex] = Coordinates of the second point
Putting the values,
Distance = [tex]\sqrt{(4.1-3.1)^2 + (-1-(-1))^2[/tex]
Distance = [tex]\sqrt{(1)^2 + (-1+1)^2[/tex]
Distance = [tex]\sqrt{(1)^2}[/tex]
Distance = 1 unit
Hence,
The points are 1 unit apart.

Use the Pythagorean’s Theorem to find the missing side of each triangle
Answer:
131 is prime. So the answer is A
Step-by-step explanation:
Remark
x is one of the legs. The other one is √65
Equation
x^2 + (√65)^2 = 14^2
Solution
x^2 + 65 = 196 Subtract 65 from both sides
x^2 = 196 - 65
x^2 = 131 Take the square root of both sides.
√x^2 = √131
x = √131

The length of a rectangle is 5(x+2) units. The width of the rectangle measures (2x-1) units. Set up and simplify an alegebraic expression to find the difference between the rectangles length and width.
Answer:
(3x + 11) units
Step-by-step explanation:
The length of a rectangle is 5(x+2) units.
The width of the rectangle measures (2x-1) units.
The difference between the rectangles length and width is given as:
Length - Width
(5(x + 2) - (2x - 1) units
(5x + 10 - 2x + 1) units
(5x - 2x + 10 + 1) units
(3x + 11) units
Therefore, the algebraic expression for the difference between the rectangles length and width is given as:
(3x + 9) units

How to solve step by step the following polynomial factoring problem:
(x + 3) - x(x^{2} + 6x+9)
Answer:
(x + 3) - x(x² + 6x + 9)
= (x + 3) - x(x + 3)²
= (x + 3)[1 - x(x + 3)]
= (x + 3)(1 - x² - 3x)
Step-by-step explanation:
Answer:
[tex](x+3)(1-x^2-3x)[/tex]
Step-by-step explanation:
First, let's factor that quadratic on the right:
[tex]x^2+6x+9[/tex] happens to factor nicely into [tex](x+3)^2[/tex], and putting that into our expression gets us
[tex](x+3)-x(x+3)^2[/tex]
Factoring out an (x + 3) from each term, we get
[tex](x+3)[1-x(x+3)][/tex]
Simplifying that expression on the right:
[tex](x+3)(1-x^2-3x)[/tex]
We can't factor that right-side expression any more, so we can just leave it like that!
Use the diagram below to solve for the missing angles, XYZ. Please help!
Answer:

180-120= 60
60÷2 =30
remaining 2 angles = 30° each
Suppose the postal service charge is $10.30 per pound on a package shipped to England what is this rate in dollars per ounce
Answer: The required rate = 0.64 per pounce.
Step-by-step explanation:
We are given that,
Postal service charge = $10.30 per pound.
As we know, 1 pound = 16 ounces.
So, Postal service charge = $10.30 per 16 ounces.
Postal service charge[tex]=\$\dfrac{10.30}{16}\ \text{ per ounce}[/tex]
[tex]\approx 0.64\text{ per ounce}[/tex]
Hence, the required rate = 0.64 per pounce.
