in the year 1918 a flu like disease occurred in Spain and spread to the rest of the world. This year 2000 another similar flu like disease has occurred in China and is spreading in the whole world Researchers have found that the likelihood of the disease Occurring again is 0. 01. Determine the overage number of flus in the next 300 years and the likelihood that in the next 300 years, the disease will occur at most five times (6marks)​

step-by-step explanation:

6.48/4 4 goes into 6.48 1.62 times

i don't know, but that looks pretty bad. my school passed us unless we failed in all the subjects, but idk abt ur school's rules.

the answer is

d.

5.3066 m2

step-by-step explanation:

x^2 + 81

we can factor this using difference of square binomials.

rewrite the equation:

x^2 - (-81)

factor:

(a^2 - b^2) = (√a^2 + √b^2)(√a^2 - √b^2)

(x^2 - (-81) = (x + √-81)(x - √-81)

we can remove the - from under the radical by multiplying it by i.

(x^2 - (-81) = (x + i√81)(x - i√81)

(x^2 - (-81) = (x + 9i)(x - 9i)

we can check our answer by using foil:

x^2 - 9ix + 9ix - 81i^2

x^2 - 81^2

i^2 = -1

x^2 + 81
