Answer:
5/ 19 ≈ 0.26 = 26%
Step-by-step explanation:
given: student is female. there is a 100% chance that the student is female
probability we want = (favorable outcomes) / (total outcomes)
total outcomes = 19 because there are 19 female students and the student must be female
favorable outcomes = 19 - 14 = 5 females who do not have an A in the class
probability = 5/ 19 ≈ 0.26 = 26%
Answer:
14
Step-by-step explanation:
The law of cosines is a² = b²+c²-2bc(cos A).
We will use s in place of a, since it is the unknown side. This makes b and c 8 and 9.
Angle A will be the angle opposite side a, or in this case side s. This makes it 111.
This gives us
s² = 8²+9²-2(8)(9)(cos 111)
s² = 64+81-2(8)(9)(cos 111)
s² = 145-144(cos 111)
s² = 196.605
Take the square root of each side:
√(s²) = √(196.605)
s = 14.02 ≈ 14
Answer: 16
Step-by-step explanation: 27-11=16
She can create 16 because there’s 4 numbers times the 4 digit code, she have 16 different possibilities of #s
Answer:
40points
Step-by-step explanation:
Given data
Let the total points the team scored be x
so that
20% of x= 8 points
let us solve for x
20/100*x= 8
0.2*x= 8
0.2x= 8
Divide both sides by 0.2
x= 8/0.2
x= 40 points
Hence the time scored 40points
