Which is the marginal relative frequency for the people who do not like cantaloupe? startfraction 25 over 91 endfraction startfraction 66 over 200 endfraction startfraction 91 over 200 endfraction startfraction 66 over 91 endfraction
The marginal relative frequency for the people who do not like cantaloupe is 0.455.
What is Marginal Relative Frequency?This refers to the addition of the joint relative frequencies in a row or column of a data table.
Hence, we would make a representation of the table from the result of the survey of 200 random people is:
Watermelon Not watermelon Total
Cantaloupe 93 16 109
Not cantaloupe 66 25 91
Total 159 41 200
So, the marginal relative frequency for the people who do not like cantaloupe is 0.455.

Answer:
x = -5/6
Step-by-step explanation:
Since it is on the unit circle
x^2 + ( -sqrt(11)/6)^2 = 1 ^2 (pythagorean theorem)
x^2 = 1 - 11/36
x^2 = 25 /36
x = +-5/6 since x is in Q III it is the negative

What is the best approximation for the perimeter of a semicircle with a diameter of 35 inches?
Use 3.14 to approximate pi.
Answer:
Circumference shares the same concept with perimeter.
First, let's use the formula for the circumference of a full circle.
C = 2πr
Where 'π' stands for pi(22/7 or 3.14) and 'r' stands for the radius.
or
C = πd
Where 'π' represents pi(22/7 or 3.14) and 'd' stands for the diameter.
But, we are trying to find a semi-circle's circumference. So, what you would do is that you would divide the whole product of the formula by 2.
For this, I'll be using this formula C = πd. Though, since we are dividing by 2 we can apply that to the diameter and make it a radius in our formula.
So the 'd' in the formula will be 'r'.
Now, let's find the radius.
D/2 = R
So,
35/2 = 17.5
Use this in our formula:-
C = πr
C = 3.14(17.5)
C = 54.95 inches.

Step-by-step explanation:
Monica is a professional musician who practices clarinet for the same amount of
time every day. After she practices clarinet for 45 min on Wednesday, she has
finished 18% of her daily clarinet practice. How many more minutes does Monica
practice clarinet on Wednesday? Show your work.
Answer:
205 minutes
Step-by-step explanation:
If Monica has already practiced 18% of her time, we know that she has practiced [tex]\frac{18}{100}[/tex]. If this 18% corresponds to 45 min, we can have the following equation: [tex]\frac{18}{100} = \frac{45}{x}[/tex]. We can rearrange the equation to find the value of x by doing [tex]x = \frac{45 \cdot 100}{18} = 250[/tex], so she practices 250 min every Wednesday. If we subtract the time she has already practiced (45 min) we find out she still has to practice more 205 min.

If a coin is tossed, a die is rolled, and a candy is taken from
of 14 candies, 7 of which are red, what
8 the probability of getting a red candy, a heads, and an odd number on the die?
Answer:
⅛
Step-by-step explanation:
There are two sides of a coin which means that the profanity of getting one side of the coin is ½.
There are 14 candies in total of which 7 are red, meaning that the probability of getting a red candy is 7/14, which is the same as ½.
There are 6 sides to a die, of which 3 sides contain the odd numbers 1,3 and 5. This would mean that the probability of getting an odd number on the die is 3/6, which is the same as ½.
Now to work out the probability of getting a red candy, a heads and an odd number on the die, you have to times the probability of each together to get you final answer.
So it will be, ½×½×½=⅛

Answer:
1. x = 3
2. s = 11
3. z = 14
4. y = 2
Step-by-step explanation:
1. x + 9 = 12
12 - 9 = x
⇒ x = 3
2. s - 1 = 10
10 + 1 = s
⇒ s = 11
3. 3 = z - 11
z - 11 = 3
11 + 3 = z
⇒ z = 14

Answer:
a = 8 2/3.
Step-by-step explanation:
The y coordinate of the point is 5, andthe x coordinate is a so substituting for these in the given equation:
3a - 4(5) = 6
3a - 20 = 6
3a = 26
a = 26/3

here , we've been given a point with coordinates ( a , 5 ) and an equation ( 3x - 4y = 6 ).
To determine - the value of aCoordinate geometry deals with parameters related to points over cartesian plane , where a points , say G , has two coordinates x and y.
the coordinates are written as ( x , y ) , where x is the x coordinate or abcissa and y is the y coordinate or ordinate.
for getting the solution to the question asked , let us think of x as a and y as 5.
Now ,
substituting the values of x and y in the equation ,
[tex]3x - 4y = 6 \\ \implies \: 3(a) - 4(5) = 6 \\ \implies \: 3a - 2 = 6 \\ \implies \: 3a = 6 + 20 \\ \implies \: 3a = 26 \\ \implies \: a = \frac{26}{3} [/tex]
let's once check , if we've arrived at the correct result or no.
This can be done , by putting value of x as [tex]\frac{26}{3}\\[/tex] which is the value of a.
So ,
[tex]3x - 4y = 6 \\ \\ \implies \: \cancel3 (\frac{26}{\cancel3} ) - 4(5) = 6\\ \\ \implies26 - 20 = 6 \\ \\ \implies \: 6 = 6[/tex]
hence , verified !
Therefore ,
[tex]\bold\red{a = \frac{26}{3} }\\ [/tex]

The glass part of a window is 32 1/2 inches wide. Including the frame on the left and right sides, the total width is 42 inches. If the left and right frames are equal, what is the width of each side of the frame?
The glass part of the frame is an illustration of fractions
The width of each side of the frame is 5 1/4 inches
How to determine the width of each side?The given parameters are:
Total width = 42 inchesGlass part = 32 1/2 inchesRepresent the width of each side with x.
So, we have:
Glass part + 2x = Total width
Substitute known values
31 1/2 + 2x = 42
Subtract 31 1/2 from both sides
2x = 10 1/2
Divide both sides by 2
x = 5 1/4
Hence, the width of each side of the frame is 5 1/4 inches
