<span>Proportions happen because two events or scenarios are related or associated with one another </span>
So,
Start with 7.
Multiply by 2.
7 * 2 = 14
Multiply by 2.
14 * 2 = 28
Multiply by 2.
28 * 2 = 56
Multiply by 2.
56 * 2 = 112
Multiply by 2.
112 * 2 = 224
Multiply by 2.
224 * 2 = 448
Multiply by 2.
448 * 2 = 896
Multiply by 2.
896 * 2 = 1792
Multiply by 2.
1792 * 2 = 3584
The first ten terms in the pattern are:
7, 14, 28, 56, 112, 224, 448, 896, 1792, 3584
In a function:
f(x) = 2x
In a rule:
S = {x| x/7 = Whole Number}
The range of a function is the set of y-coordinates.
The y-coordinates are 1, 4, 4, 2.
In a set you only put each number once, so the range is {1, 2, 4}.
Answer:
5
Step-by-step explanation:
Tina started with $20, but had to spend $3.25 on the bat.
$20-$3.25 = $16.75, which is all she has left for rounds.
Each round costs $3.00
$16.75 divided by $3.00 comes out to 5.58 rounds, but since she can't play 1/2 a round, that means she could only play 5 rounds
5 rounds X $3.00 per round comes to $15.00
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)
