Answer:

175

Step-by-step explanation:

It is much easier if you use the unit rate, so we'll convert the first senta\ence into a ratio. 2 cubic feet:90lb. you need to get 1 cubic foot, so divide both sides my 2, 1 cubic foot:35 pounds. now, to get five cubic pounds(See where this is going?) you multiply both sides by 5.  5 cubic feet:175lb

(these idoits make you go back and forth in solving problems)

Liz flips a coin 30 times. The coin lands heads up 21 times and tails up 9 times. Complete each
SSSSS [86.1K]

Answer:

Pr = 0.50

Step-by-step explanation:

Given

n = 30

H = 21

T = 9

See attachment for complete question

Required

P(H)

The question requires that we calculate the theoretical probability of landing on the head.

This means that, we have to ignore the given data, and we use the following

S =\{H,T\} --- sample space

n(S) = 2 --- sample size

n(H) = 1 --- occurrence of Head

So, the theoretical probability is:

Pr = n(H)/n(S)

Pr = 1/2

Pr = 0.50
