There are four scores.
So to find the mean or average, you add all four scores and then divide by 4.
I get 119, then divide by 4, to get 29 and 3/4 or 29.75.
Answer:
1.235%
Step-by-step explanation:
Paso 1
Calculamos el costo de envío
= $ 1620 - $ 1600
= $ 20
Paso 2
¿Cuál es el porcentaje de mi compra que me cobraron por los gastos de envío?
Esto se calcula como:
(Costo de envío / Cargos totales) × 100
= 20/1620 × 100
= 1.2345679012%
= Aproximadamente = 1.235%
29 36 39 45 49 51
39 + 45 = 84
84 ÷ 2 = 42
Answer: Median is 42.
The part of the quadratic formula that dictates whether the function is factorable or not is B. b^2 - 4ac. This determines the number of real, imaginary, negative and positive roots.
In the equation <span>2x^2 + 7x + 3,
we use the quadratic formula
x = -b +- sqrt (b2 -4ac) /2a = -7 +- </span><span>sqrt (49 -24) /4
the answers are x1 =-0.5 and x2 = -3.</span>
