V (-1,-9)
Y=1(x+1)^2-9
If you’re talking about the value of x in the quadratic equation then it is x=-4 &x=2
Answer:
mode = the most
mean =average of the numbers: a calculated "central" value of a set of numbers. ... add up all the numbers, • then divide by how many numbers there are.
median=The middle number; found by ordering all data points and picking out the one in the middle (or if there are two middle numbers, taking the mean of those two numbers).
<h3>
Mark</h3>
Now we arrange all Mark's test scores first (arrange in a sequence), so it will become :
71, 74, 76, 82, 83, 94, 94
mode = 94
mean = (71 +74+76+82+83+94+94) over 7
= 574 over 7
= 82
median = 82
<h3>
Irina</h3>
Now we arrange all Irina's test scores first (arrange in a sequence too) , so it will become :
79, 79, 82, 83, 89, 95, 95
mode (there are 2 modes in Irina test) which is 79 and 95 because both of them appears twice.
mean = (79+79+82+83+89+95+95) over 7
= 602 over 7
= 86
median = 83

HOPE IT HELP</h3>
Answer:
3 segundos
Step-by-step explanation:
De la pregunta anterior, se nos dice que:
En un evento de natación, Mario hizo el curso en ¾ de minuto
1 minuto = 60 segundos
Por lo tanto = 3/4 de minuto
= 3/4 × 60 segundos
= 45 segundos
David completó el curso en 4/5 de un minuto.
1 minuto = 60 segundos
Por lo tanto = 4/5 de un minuto
= 4/5 × 60 segundos
= 48 segundos
La diferencia entre los dos competidores se calcula como
48 segundos - 45 segundos
= 3 segundos.
Por lo tanto, la diferencia entre los dos competidores = 3 segundos.
