Answer: 3/8

Step-by-step explanation:

When three coins are flipped, we get 8 total outcomes: (HHH,HHT,HTH,HTT,THH,THT,TTH,TTT)

Two tails and one head is (HTT, TTH, THT)

Probability = number of favorable outcomes/ number of total outcomes

Number of Favorable outcomes = 3

Number of Total outcomes= 8

Therefore, probability of getting 2 tails and one head

= 3/8

A woman bought 50 meters of cloth at 60 cedis . she sold the cloth at 1.50 cedis per meter. Find her percentage profit.

Usimov [2.4K]

Answer:

Which function f (x) , graphed below, or g (x) , whose equation is g (x) = 3 cos 1/4 (x + x/3) + 2, has the largest maximum and

Leya [2.2K]

Answer:

g(x), and the maximum is 5

Step-by-step explanation:

for given function f(x), the maximum can be seen from the shown graph i.e. 2

But for the function g(x), maximum needs to be calculated.

Given function :

g (x) = 3 cos 1/4 (x + x/3) + 2

let x=0 (as cosine is a periodic function and has maximum value of 1 at 0 angle)

g(x)= 3 cos1/4(0 + 0) +2

= 3cos0 +2

= 3(1) +2

= 3 +2

= 5 !

Given the data set (200, 150, 325, 350, 100, 75), Find the range of the data set

andriy [413]

The range is just the distance between the biggest number
and the smallest one.

The biggest number on that list is 350 .
The smallest number on that list is 75 .

The range is from 75 to 350, or a distance of 275 .
