The answer is yes, every 5 dollars there is an extra 0.35$ tax so it’s a straight line which means that it is proportional
Answer:
El 40% de los estudiantes reprobaron la asignatura.
Step-by-step explanation:
Dado que sabes el número total de estudiantes y cuántos aprobaron la asignatura, puedes restar el número de estudiantes que aprobaron del total de estudiantes para encontrar los estudiantes que reprobaron la asignatura:
50-30=20
Ahora puedes calcular el porcentaje dividiendo el número de estudiantes que reprobaron entre el total de estudiantes y multiplicando el resultado por 100:
20/50*100=40%
De acuerdo a esto, la respuesta es que el 40% de los estudiantes reprobaron la asignatura.
Answer:
b = 53
c = 53
Step-by-step explanation:
Alright so we already know that b and c are going to have the same angle measures. We can find b by subtracting 180 degrees to 127. Why you may ask? Its because when b and 127 are added together its obvious that it creates a straight line (supplementary angle). This means that two angles will sum up to 180 degrees. We can create an easy equation and solve for b.
127 + b = 180
b = 53 and c = 53
Best of Luck!
Do you have an equation that I can use?
Answer: If it is probability, there is a 40% chance that a school will receive a defective calculator if the selections are random.
If the calculators are tested and sorted, there can be 3 selections of 4 calculators sent to schools once the 8 defective ones are removed.
Step-by-step explanation: The question is unclear. Is it about subtracting the bad ones and dividing the good ones? Or is it about Taking chances with the selection of calculators to be sent?
If they subtract: 20-8= 12 left 12÷4= 3 sets of good ones.
If they take chances 8/20 = .4 so there is a 40% chance that a bad calculator will be included in the selection.
