true
Step-by-step explanation:
Answer:
$122.28
Step-by-step explanation:
Give the following :
Insurance worth = $240,000
Price sold = $225
P(survival) = 0.999572
P(death) = 1 - 0.999572 = 0.000428
If she survives, insurance firm makes $225
If she dies, insurance firm pays $240,000, hence the company losses :
$(225 - 240,000) = $−239775
Expected value (E(x)) = sum of P(i) * X(i)
E(x) = (P(survival) * profit made) + (P(death) * loss incurred)
E(x) = (225 * 0.999572) + (0.000428 * −239775)
= 224.9037 - 102.6237
=$ 122.28

Answer:
A altura máxima é 5
Step-by-step explanation:
Matematicamente, a altura máxima pode ser obtida
A altura máxima é simplesmente o vértice da parábola
Começamos diferenciando a função Isso será -8x
Agora, defina -8x como 0
Isso significa que x = 0
Agora, substitua x = 0 de volta na equação temos
f (0) = -4 (0) ^ 2 + 5
f (0) = 5
A altura máxima é 5
