ezz multiply and see what it s if its wrong then txt me
Step-by-step explanation:
To find the median, place the given numbers in order of their value and find the middle number.
Here we have:
57, 61, 58, 54, 68, 51, 49, 64, 50, 48, 65, 52, 56, 46, 47, 55, 42, 60, 62, 43, 69, and 70.
Arranging them in order from least to greatest, we have:
42, 43, 46, 47, 48, 49, 50, 51, 52, 54, 55, 56, 57, 58, 60, 61, 62, 64, 65, 68, 69, and 70.
There are 22 numbers total; the median will be the mean of the middle two numbers, which are 55 and 56.
To find the mean, add the numbers together and divide the sum by 2.
55 + 56 = 111
111 / 2 = 55.5
The median of the ages of the US Presidents at the time of their inauguration is 55.5 years.
-2x + 4y = 22
-2x - 3y = 8
Subtract 2nd from 1st equation,
7y = 14
y = 14/7 = 2
Substitute it in 1st equation,
-2x + 4(2) = 22
-2x = 22 - 8
x = -14/2
x = -7
In short, Your Answer would be (-7, 2)
Hope this helps!
Answer:
R $ 3855
Step-by-step explanation:
João comprou uma TV por R $ 2400,00; um celular por R $ 1350,00 e um tênis por R $ 130,00 qual o valor total da compra?
O preço total de compra é calculado como:
Custo da TV + Custo do Celular + Custo do Tênis
R $ 2400,00 + R $ 1350,00 + R $ 130,00,
= R $ 3855
