Answer:
a) the temperature is y = 16° C at 9 AM.
b) The probability of selecting 2 vowels at the same time is 2.8%
Step-by-step explanation:
a)
Temperature = y=?
Time = x = 9 A.M
The given equation is:
Putting x = 9 and solving
So, the temperature is y = 16° C at 9 AM.
b)
WORD CLEMSON
Total Words = 7
Vowels = e, o = 2
Probability of selecting 2 vowels at the same time = P(2 Vowels) =?
We will use the formula of combinations nCr = n! / r! (n-r)!
As we are selecting three letter out of 7, the sample space will be 7C3
And
As there are only two vowels in the given word, and we have to find the probability of selecting two vowels so our event space will be 2C2.
P(2 Vowels) = 2C2 / 7C3
= 1/35
= 0.028 = 2.8%
So, The probability of selecting 2 vowels at the same time is 2.8%
