The h(t) at a certain period when the penny is dropped in the ground is zero. Substituting the known values in the equation will give us an expression of,
0 = -4.9t² + 0 + 150
v₀ is zero in the assumption that the dropping is free. Solving for t of the equation,
t = 5.53 seconds

an aeroplane is flying with a help of 300 km per hour who much distance will it cover in 160 minute

uysha [10]

Answer:

800 km

Step-by-step explanation:

Does the plane have a speed of it's own? I don't see it, so will assume the plane is simply travelling at 300 km/h.

(300 km/hr)*(1 hr/60 min) = 5 km/min

(5 km/min)*(160 min) = 800 km in 160 minutes

A certain drug treatment cures 90% of cases of hookworm in children.18 Suppose that 20 children suffer- ing from hookworm are to

Anni [7]

Answer:

Step-by-step explanation:

Here X the no of children suffering from hookworm treated and recovered is binomial because

a) Each child is independent of the other

b) There are only two outcomes

c) The probability for any child to recover is constant as 90% = 0.9

X is Bin (20,0.9)

a) Prob that all 20 will be cured

=P(X=20)= $0.9^{20} \\=0.1216$

b) Prob all but 1 will be cured= $P(x=1) = 20C1 (0.9) (.1)^{19} \\=1.8(10^8)$

c) Prob exactly 18 will be cured

$=P(X=18)\\=20C18 (0.9)^{18} (0.1)^2\\= 0.2852$

d) Prob exactly 90% will be cured.

= $P(X=18)\\=20C18 (0.9)^{18} (0.1)^2\\= 0.2852$
