Step-by-step explanation:
The group that had the highest percentage of students that like Sports is group B.
The group that had the less percentage of students that like English is group A.
the percentage of students like Math in group A is 30% and 10% in group B
<h3>What are the percentages?</h3>
A pie chart is a graph that displays information in a circle. The circle is divided into slices which represent a numerical proportion. The sum of angles in a pie chart is 360 degrees
Percentage of students that like sports in:
- Group A = [20 / (20 + 15 + 5 + 10)] x 100 = 40%
- Group B = [22 / (5 + 4 + 9 + 22)] x 100 = 55%
Percentage of students that like English in:
- Group A = [5 / (20 + 15 + 5 + 10)] x 100 = 10%
- Group B = [5 / (5 + 4 + 9 + 22)] x 100 = 22.5%
Percentage of students that like Maths in:
Group A = [15 / (20 + 15 + 5 + 10)] x 100 = 30%
- Group B = [4 / (5 + 4 + 9 + 22)] x 100 = 10%

Answer:
x = negative 9/4
Step-by-step explanation:
-2x-11=6x+7
-2x-11+11=6x+7+11
-2x=6x+18
-2x-6x=6x+18-6x
-8x=18
The number of permutations of the 4 different letters, taken two at a time, is given by:
Answer:
7.30167%
Step-by-step explanation:
Usando la fórmula de puntuación z
z = (x-μ) / σ, donde x es la puntuación bruta, μ es la media de la población y σ es la desviación estándar de la población
Para x <0.20 pulgadas
z = 0.20 - 0.25 / 0.02
z = -2.5
Valor de probabilidad de Z-Table:
P (x <0.20) = 0.0062097
Para x> 0.28 pulgadas
z = 0.28 - 0.20 / 0.02
z = 1.5
Valor de probabilidad de Z-Table:
P (x <0.28) = 0.93319
P (x> 0.28) = 1 - P (x <0.28) = 0.066807
La probabilidad de que se produzcan tornillos defectuosos cuando el tornillo se considera defectuoso si su diámetro es inferior a 0.20 pulgadas o superior a 0.28 pulgadas es
P (x <0.20) + P (x> 0.28)
= 0.0062097 + 0.066807
= 0.0730167
Conversión a porcentaje
= 0.0730167 × 100
= 7.30167%
El porcentaje de tornillos defectuosos producidos es
7.30167%
