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)
Answer:
364000
Step-by-step explanation:
Answer:
no solution
Step-by-step explanation:
y = x+1 and y = x + 2 don't touch because they are parallel
if you don't know what parallel means, just search it up, but i can explain it to you:
parallel means same slope or same steepness of line
this triangle is obtuse meaning the degree it's currently at is 270°
Answer:
The 29th term is
<h2>243</h2>
Step-by-step explanation:
The above sequence is an arithmetic sequence
For an nth term in an arithmetic sequence
U(n) = a + ( n - 1)d
where n is the number of terms
a is the first term
d is the common difference
From the question
a = - 121
d = -108 -- 121 = - 108 + 121 = 13
Since we are finding the 29th term
n = 29
The 29th term of the sequence is
U(29) = - 121 + ( 29 - 1) 13
= -121 + 28(13)
= -121 + 364
The final answer is
<h2>243</h2>
Hope this helps you
