Answer:
a)45/125
b)25/125
c)80/125
d)45/125
e)10/35
Step-by-step explanation:
hope it is correct
The statements which are correct are B, C and E.
What is Relative Frequency?Relative frequency is defined as the ratio of the frequency by the total count of the data values.
We have to find the relative frequency in each option.
A) Frequency of "like snowmobiles" and "like skateboards" = 80
Total count = 160
Relative frequency of "like snowmobiles" and "like skateboards" = 80 / 160 = 0.5 = 50%
B) Frequency of "like snowmobiles" and "do not like skateboards" = 25
Total count = 160
Relative frequency of "like snowmobiles" and "do not like skateboards" = 25 / 160 = 0.15625 = 15.6%
C) Frequency of "like snowmobiles" and "like skateboards" = 80
Total row frequency = 105
The row conditional relative frequencies of "like snowmobiles" and "like skateboards" = 80 / 105 = 0.7619 = 76.19% ≈ 76.2%
D) Frequency of "do not like snowmobiles" and "like skateboards" = 45
Total row frequency = 55
The row conditional relative frequencies of "do not like snowmobiles" and "like skateboards" = 45 / 55 = 0.81818 = 81.82%
E) Frequency of "do not like snowmobiles" and "do not like skateboards" = 10
Total column frequency = 35
The column conditional relative frequencies of "do not like skateboards" and "do not like snowmobiles" = 10 / 35 = 0.2857 = 28.57% ≈ 28.6%
Hence the correct statements are B, C and E.

but he learns 2 each week. How many weeks (w) will it
be before Aiden knows as many songs as John?
Answers
Answer:
8 weeks
Step-by-step explanation:
Let
w = number of weeks
John = 12 + w
Aiden = 4 + 2w
How many weeks (w) will it be before Aiden knows as many songs as John?
Equate both John and Aiden expression
John = Aiden
12 + w = 4 + 2w
Collect like terms
12 - 4 = 2w - w
8 = w
w = 8 weeks
It will take 8 weeks before Aiden knows as many songs as John

Step-by-step explanation:
The various forms of the expression use the relation ...
-5 1/4 = -5 + -1/4 = -(6 -3/4) = -6 +3/4
Of course, the minus sign in a product can be moved around according to the associative and commutative properties of multiplication.
(8)(-5 1/4)
= (8)(-5 + -1/4)
= 8(-5) +8(-1/4)
= 8(-5) -8(1/4)
= 8(-6 +3/4)

Una muestra de 800 gramos de avellana con cáscara tiene 500 gramos de grano. ¿cuántosgramos de grano habrá en 2,4 kg de avellana con cáscara?
Answers
Answer:
1500 grams of grain
Step-by-step explanation:
How many grams of grain will there be in 2.4 kg of shelled hazelnuts?
Step 1
Convert kg to g
1 kg = 1000g
2.4 g = x
Cross Multiply
x = 2.4 × 1000g = 2400g
Step 2
An 800 gram sample of shelled hazelnuts has 500 grams of grain.
Hence,
800g hazelnuts = 500 gram of grain
2400g hazelnuts = x
Cross Multiply
800x = 2400g × 500g
x = 2400g × 500g/800
x = 1500 grams of grain

Which equation represents the graph ?
Answers
Answer:
The equation of the line is;
y + 4 = 3(x + 4)
Step-by-step explanation:
The general equation of a line is;
y = mx + b
where m is the slope and b is the y-intercept
To get the equation, let us look at the given intercepts
We have the intercepts at the point (0,5) and (-2,-1)
We have the slope of the line as follows;
m = (y2-y1)/(x2-x1) = (-1-5)/(-2-0) = -6/-2 = 3
So we have the equation as;
y = 3x + b
recall, we have the y-intercept as 5
so the complete equation is;
y = 3x + 5
Now, we can rewrite this as;
y+ 4 = 3(x + 3)

Two years ago there were 20 trailer homes on Elm Street with an average age of 18 years. At that time, a group of brand new trailer homes was then added to Elm Street. Today, the average age of all the trailer homes on Elm Street is 14 years. How many new trailer homes were added two years ago?
Answers
Answer:
The number of new trailer homes that were added two years ago is 10
Step-by-step explanation:
Given that
Twenty years ago there are 20 trailer homes having an average age of 18 years
Today, the average of the age is 14 years
We need to find out the number of new trailer homes that would be added two years ago
Since as of now 20 trailer homes would be an average of 20 years and we assume the new trailers be n that are 2 years old
So
20 + n
And, the sum of their ages i.e. (20) ( 20) + 2n
Now the following equation is used
[tex]\frac{400 + 2n}{20 + n} = 14[/tex]
400 + 2n = 14(20 + n)
400 + 2n = 280 + 14n
120 = 12n
n = 10
Hence, the number of new trailer homes that were added two years ago is 10

Cost of electricity = xCost of gas = yBased on the given, we have equations:
300x + 120y = 114290x + 150y = 115.30Multiply the first equation by 29 and the second one by 30, then subtract the first equation from the second:
30*(290x) - 29(300x) + 30(150y) - 29(120y) =30(115.3) - 29(114)4500y - 3480y = 1531020y = 153y = 153/1020y = 0.15The cost per unit of gas is $0.15

Given:
[tex]P(A)=0.4, P(B)=0.7, P(A\text{ and }B)=0.3[/tex]
To find:
The value of [tex]P(A\text{ or }B)[/tex].
Solution:
We know that,
[tex]P(A\text{ and }B)=P(A\cap B)[/tex]
[tex]P(A\text{ or }B)=P(A\cup B)[/tex]
It means, we have [tex]P(A)=0.4, P(B)=0.7, P(A\cap B)=0.3[/tex] and we need to find the value of [tex]P(A\cup B)[/tex].
[tex]P(A\cup B)=P(A)+P(B)-P(A\cap B)[/tex]
[tex]P(A\cup B)=0.4+0.7-0.3[/tex]
[tex]P(A\cup B)=1.1-0.3[/tex]
[tex]P(A\cup B)=0.8[/tex]
Therefore, the value of [tex]P(A\text{ or }B)[/tex] is 0.8.

Suppose that the height (in centimeters) of a candle is a linear function of the amount of time (in hours) it has been burning. After 5 hours of burning, a candle has a height of 21.5 centimeters. After 21 hours of burning, its height is 16.7 centimeters. What is the height of the candle after 15 hours?
Answers
Answer:
The height is 18.5cm
Step-by-step explanation:
Given
Let
[tex]y =height[/tex]
[tex]x = time[/tex]
So, we have:
[tex](x_1,y_1) = (5,21.5)[/tex]
[tex](x_2,y_2) = (21,16.7)[/tex]
Required
The height after 15 hours
First, calculate the slope (m)
[tex]m = \frac{y_2 - y_1}{x_2 - x_1}[/tex]
This gives:
[tex]m = \frac{16.7-21.5}{21-5}[/tex]
[tex]m = \frac{-4.8}{16}[/tex]
[tex]m = -0.3[/tex]
The linear equation is then calculated as:
[tex]y =m(x - x_1) + y_1[/tex]
Where
[tex]m = -0.3[/tex]
[tex](x_1,y_1) = (5,21.5)[/tex]
This gives:
[tex]y =-0.3(x - 5) + 21.5[/tex]
Open bracket
[tex]y =-0.3x + 1.5 + 21.5[/tex]
[tex]y =-0.3x + 23[/tex]
After 15 hours
[tex]x = 15[/tex]
[tex]y =-0.3*15 + 23[/tex]
[tex]y =-4.5 + 23[/tex]
[tex]y =18.5[/tex]
The height is 18.5cm
