2/3; 30 €
Explicación paso a paso:
Fracción gastada en ropa = 2/8
Fracción gastada en dulces = 1/12
Fracción restante:
1 - (Fracción gastada en ropa + fracción gastada en dulces)
1 - (2/8 + 1/12)
L. C. M de 8 y 12 = 24
1 - (6 + 2) / 24
1 - 8/24
1 - 1/3
= (3 - 1) / 3
= 2/3
Si la paga era de 45;
Cantidad restante: 2/3 de 45
= 90/3
= 30 €
Answer:
interval = [17.3948 , 20.6052]
Step-by-step explanation:
given,
random sample (n) = 45
average product lifespan = 19 years
standard deviation = 4 years
confidence interval of 99 % = ?
we know,
t* = qt(1.99/2 + 44 ) = qt(0.995,44)
t* = 2.692
so,
interval
interval = [19 - 1.6052 , 19 + 1.6052]
interval = [17.3948 , 20.6052]
$20×.25=$5
$20-$5=$15
$15×.15=$2.25
$15+$2.25=$17.25
$17.25 is your answer
Answer:
46.95 in.²
Step-by-step explanation:
Surface area of the kaleidoscope = surface area of a triangular prism = 2(BA) + P*H
Base area (B) = 2(½*bh) = 2(½*1.5*1.3) = 1.95 in.²
Perimeter of base (P) = 1.5 + 1.5 + 1.5 = 4.5 in.
Height of prism (H) = 10 in.
Plug in the values
Surface area = 1.95 + 4.5*10 = 46.95 in.²
