$63.54 is the price after the discount and tax
Answer:
aₙ= 4n+11
Step-by-step explanation:
the sequence 15, 19, 23, 27
is AP with the first term 15 and
the common difference 19-15=23-19=27-23= 4
aₙ= a₁+(n-1)d
aₙ= 15+(n-1)*4= 15+4n- 4= 4n+11
aₙ= 4n+11
Great job man!!!!!!!!!!!!
Answer:
The value of the variable 'b' is 3 and GH is 9
Step-by-step explanation:
Given:

H is between G and I
Such that G - H - I
To Find:
GH = ?
Solution:
On Substituting HI we get

Substituting 'b' in HI and GI we get


Now, by Line Addition Property we get

Substituting 'HI' and 'GI' we get

The value of the variable 'b' is 3 and GH is 9
Using the binomial probability relation ; the probability that an head is obtained at least 50 times is 0.0271
<u>Using the binomial probability relation</u> :
- P(x = x) = nCx * p^x * q^(n-x)
- p = probability of success = 0.4
- q = 1 - p = 0.6
- n = number of trials = 100
P(x ≥ 50) = p(x = 50) + p(x = 51) + ...+ p(x = 100)
<u>Using a binomial probability calculator</u> :
P(x ≥ 100) = 0.0271
Therefore, the probability that atleast 50 heads are obtained in the trial is 0.0271
