Answer:
8/3 = 2 2/3
Step-by-step explanation:
(2/7)y + (3 1/7)y = (3 3/7)y = (24/7)y
For y=7/9, this is ...
(24/7)(7/9) = 24/9 = 8/3
The value of the expression for y=7/9 is 8/3.
Answer:
y = 5x
Step-by-step explanation:
X=5 and Y=1
Direct variation can be represented by the equation y=kx.
Therefore,
1 = k(5)
5 = k
Now you use, k = 5 to write the direct variation equation.
Which gives you the answer y = 5x
Answer:
Intervalo de confianza
= (0.294, 0.386)
Step-by-step explanation:
La fórmula para el intervalo de confianza para la proporción se da como
p ± z × √p (1 - p) / n
Donde p = x / n
De donde de la pregunta anterior
x = 136 personas
n = 400 personas
p = 136/400
p = 0.34
z = puntuación z del intervalo de confianza del 95% = 1.96
Por lo tanto,
Intervalo de confianza =
0.34 ± 1.96 × √0.34 (1 - 0.34) / 400
= 0.34 ± 1.96 × √0.34 × 0.66/400
= 0.34 ± 1.96 × √0.000561
= 0.34 ± 1.96 × 0.0236854386
= 0.34 ± 0.0464234596
Intervalo de confianza
= 0.34 - 0.0464234596
= 0.2935765404
= 0.34 + 0.0464234596
= 0.3864234596
Hence:Intervalo de confianza
= (0.294, 0.386)
