2. The applicable rules of exponents are ...

  (a^b)(a^c) = a^(b+c)

  a^b = 1/a^-b

__

  \dfrac{4^8}{(4^2)^{-3}}\div 4^4=\dfrac{4^8}{4^{-6}\cdot4^4}=\dfrac{4^8}{4^{-2}}\\\\=4^8\cdot4^2=4^{10}

21/2 or 10 1/2
Explanation:
8 3/4 is the same as 35/4

so Darcy harvests 35/4 per 5/6 hours
to figure out how much is harvested in one hour, you divide the amount harvested by the amount of hours taken to harvest it.
35/4 ÷ 5/6 =35/4 × 6/5

35/4 × 6/5 = 7/2 × 3/1 = 21/2

so the answer is 21/2 or 10 1/2

A dart is to be thrown at a target. The probability the dart will hit the target (yes or no) on a single attempt is 0.20. Each t
MArishka [77]

Answer:

0.04

Step-by-step explanation:

Given that a dart is to be thrown at a target. The probability the dart will hit the target (yes or no) on a single attempt is 0.20

Each throw is independent of the other throws.

Let x be the no of times the target is hit in the trial of 4 throws

Since each outcome is independent of the other X is binomial with n =4 and p = 0.20

Required probability

=  the probability that it will take less than or equal to 4 throws to hit the target on both successful target hits

=P(X=2 when n =2) + P(x=2 when x =3) + P(x=2 when x =4)

= (0.2)^2 + 3C2 (0.2)^2(0.98)+4C2 (0.2)^2 (0.98^2)\\=0.04
