Relative frequency is frequency relative to some quantity, usually the marginal or total frequency. The needed relative frequencies are: 14/50, 15/50, and 44/50 respectively.
How to find the relative frequency?Relative frequency is the ratio of the considered sub group's count to the total count. (so its frequency of the considered sub group relative to the total frequency).
The two way table given is:
Alaska Not Alaska Total
Hawaiii 6 15 21
Not Hawaii 8 21 29
Total 14 36 50
Calculating the needed relative frequencies one by one:
Case 1: The relative frequency for students who have been to Alaska
Total students who went to Alaska= 14Total number of students in survey = 50Thus, the relative frequency for students who have been to Alaska (relative to total count) is 14/50
Case 2: The relative frequency for students who have been to Hawaii but not Alaska
Total students who went to Hawaii but not Alaska= 15Total number of students in survey = 50Thus, the relative frequency for students who have been to Alaska (relative to total count) is 15/50
Case 3: The relative frequency for students who have not been to Alaska or Hawaii
Total students who haven't been to Alaska or Hawaii = total students's count - those who have been to both Hawaii and Alaska = 50 - 6 = 44Total number of students in survey = 50Thus, the relative frequency for students who have been to Alaska (relative to total count) is 44/50
Thus, the needed relative frequencies are: 14/50, 15/50, and 44/50 respectively.

Answer:
(- [tex]\frac{1}{5}[/tex] , 0 )
Step-by-step explanation:
to find where the line crosses the x- axis, let y = 0 in the equation and solve for x
5x - 2(0) + 1 = 0
5x - 0 + 1 = 0
5x + 1 = 0 ( subtract 1 from both sides )
5x = - 1 ( divide both sides by 5 )
x = - [tex]\frac{1}{5}[/tex]
the line crosses the x- axis at (- [tex]\frac{1}{5}[/tex], 0 ) or ( - 0.2, 0 )
Answer:
(-1/5, 0).
Step-by-step explanation:
Where the line crosses the axis the value of y = 0.
5x - 2y + 1 = 0
Let y = 0, then:
5x - 2(0) + 1 = 0
5x + 1 = 0
5x = -1
x = -1/5.
So the point is (-1/5, 0).

1. Given: LMN ~ QPR, find RQ.
Answer:
C. 27
Step-by-step explanation:
If those two triangles are similar then look at how much one side is being increased to the other triangle. ML is similar to PQ and it increases by 1.5 to get there.
So find the side similar to RQ which is LN
1.5(x+7)=2x+5
1.5x+10.5=2x+5
5.5=0.5x
x=11
Then plug in 11 for x to find RQ which will be 27

What is an inequality?In mathematics, "inequality" refers to a relationship between two expressions or values that are not equal to each other. To solve the inequality, you may multiply or divide each side by the same positive number, add the same amount to each side, take the same amount away from each side, and more. You must flip the inequality sign if you multiply or divide either side by a negative number.
Given:
An inequality,
x − y < z.
To solve for x:

 Which of the following side lengths do not make up a right triangle?
A. 3,4,5
B. 5,12,13
C. 7,22,25
D. 8,15,17
Answer:
C. 7,22,25
Step-by-step explanation:
A. 3,4,5
=> p² + b² = h²
=> 3²+4² = 5²
=> 9+16 = 25
=> 25 = 25
B. 5,12,13
=> 5² + 12² = 13²
=> 25 + 144 = 169
=> 169 = 169
C. 7,22,25
=> 7² + 22² = 25²
=> 49 + 484 = 625
=> 533 ≠ 625
D. 8,15,17
=> 8² + 15² = 17²
=> 64 + 225 = 289
=> 289 = 289
so, the side that lengths do not make up right triangle is C. 7,22,25

Answer:
b
Step-by-step explanation:
Use the method of elimination to solve the pair of simultaneous equation 2x+5y=4,2x-2y=18
[tex]2x+5y= 4~~~...(i)\\\\2x-2y = 18~~~...(ii)\\\\(ii) -(i):\\\\~~~~~2x-2y -2x -5y= 18 -4\\\\\implies -7y = 14\\\\\implies y = -\dfrac{14}7\\\\\implies y= -2\\\\\text{Substitute}~ y=-2~ \text{ in eq (i):}\\\\~~~~~~2x+5(-2) = 4\\\\\implies 2x-10 = 4\\\\\implies 2x = 10+4\\\\\implies 2x =14\\\\\implies x = \dfrac{14}2\\\\\implies x =7\\\\\text{Hence}~ (x,y) =(7,-2).[/tex]
Answer:
y = -2
x = 7
Step-by-step explanation:
Solving simultaneous equation
2x + 5y = 4 ---------------(I)
2x - 2y = 18 -----------(II)
Now, multiply equation (II) by (-1) and then add the equations. So that, 'x' will be eliminated and we can find the value of 'y'
(I) 2x + 5y = 4
(II)*(-1) -2x + 2y = - 18 {Now add}
7y = -14
y = -14/7 {on dividing both sides by 7}
[tex]\sf \boxed{y= -2}[/tex]
Now plugin y = -2 in equation (I)
2x + 5*(-2) = 4
2x - 10 = 4
2x = 4 + 10 {on adding 10 to both sides}
2x = 14
x = 14/2 {Divide both sides by 2}
[tex]\sf \boxed{x = 7}[/tex]

Value of x is 36 (El valor de x es 36)Step-by-step explanation:
In this question we have given with an equation that is -6x + 71 = -4x - 1 . And have to find the value of x .
( En esta pregunta hemos dado con una ecuación que es -6x + 71 = -4x - 1 . y hay que encontrar el valor de x )
Solution : -
( Soluciones : - )
[tex] \quad : \implies - 6x + 71 = - 4 - 1[/tex]
Step 1 : Subtracting 71 on both sides :
( Paso 1 : Restando 71 en ambos lados: )
[tex]\quad : \implies - 6x + \cancel{71} - \cancel{71} = - 4x - 1 - 71[/tex]
On calculating further, We get :
( Al calcular más, obtenemos : )
[tex]\quad : \implies - 6x = - 4x - 72[/tex]
Step 2 : Adding 4x on both sides :
( Paso 2 : Sumando 4x en ambos lados: )
[tex]\quad : \implies - 6x + 4x = - \cancel{4x} + \cancel{4x } - 72[/tex]
On calculating further, We get :
( Al calcular más, obtenemos : )
[tex]\quad : \implies \cancel{-} 2x = \cancel{-}72[/tex]
Step 3 : Dividing by 2 on both sides :
( Paso 3 : Dividiendo por 2 en ambos lados: )
[tex]\quad : \implies \frac{ \cancel{2}x}{ \cancel{2} } = \cancel{\frac{72}{2} }[/tex]
On calculating further , We get :
( Al calcular más, obtenemos : )
[tex]\quad : \implies \: \green{ \boxed{ \frak{x = 36}}}[/tex]
Therefore , value of x is 36 . ( Por lo tanto , el valor de x es 36 . )Verifying : -
( Comprobación :- )
We are verifying our answer by substituting value of x in given equation. So ,
( Estamos verificando nuestra respuesta al sustituir el valor de x en la ecuacióndada. Asi que, )
-6x + 71 = -4x - 1 -6 ( 36 ) + 71 = -4 ( 36 ) - 1-216 + 71 = -144 - 1-145 = -145L.H.S = R.H.S (Lado izquierdo = Lado derecho )Hence, Verified. ( Por lo tanto, Verificado. )Therefore, our solution is correct.

A bakery sells mocha cupcakes and chocolate cupcakes. One day it sold 238 mocha and 42 chocolate. What percent of the cupcakes sold that day were mocha?
Answer:
35%
Step-by-step explanation:
The required percentage of the mocha cupcakes that were sold that day is 85%.
Given that,
A bakery sells mocha cupcakes and chocolate cupcakes. One day it sold 238 mochas and 42 chocolate. What percent of the cupcakes sold that day were mocha is to be determined.
The percentage is the ratio of the composition of matter to the overall composition of matter multiplied by 100.
Here,
Number of mocha cupcakes = 238
Number of chocolate cupcakes = 42
Total cupcakes = 238 + 42 = 280
Percentage of mocha sold = 238/280 = 0.85 or 85%
Thus, the required percentage of the mocha cupcakes that were sold that day is 85%.

Answer:
ummmm..... let's see..
Step-by-step explanation:
using "Almighty formula"
{Y = –x +/– √b^2 – 4ac / 2a}
so we name all the values behind the coefficients which are; –1^2, 8 and 11
so let's assign a,b,c to these values:
a =–1, b =8, c = 11
all you just do now is to add these values to the formula
you should be having Y =1 +/– √8^2 – 4×–1×11

2×–1
Y =1 +108
———— or Y = 1–108
