Write a rule for the nth term of the sequence 15, 19, 23, 27
Mkey [24]

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

Find the value of the variable and GH if H is between G and I. GI=5b+1, HI=4b-5, HI=7
fgiga [73]

Answer:

The value of the variable 'b' is 3 and GH is 9

Step-by-step explanation:

Given:

GI = 5b+1\\\\HI=4b-5\\ \\HI=7

H is between G and I

Such that G - H - I

To Find:

GH = ?

Solution:

On Substituting HI we get

4b-5=7\\\\\therefore 4b=7+5=12\\\\b=\dfrac{12}{4}=3

Substituting 'b' in HI and GI we get

HI=4\times 3 -5=12-5=7\\\\\therefore HI = 7

GI=5\times 3 +1=15+1=16\\\\\therefore GI = 16

Now, by Line Addition Property we get

GI=GH+HI

Substituting 'HI' and 'GI' we get

16=GH+7\\\\\therefore GH=16-7=9

The value of the variable 'b' is 3 and GH is 9

A biased coin has a probability of 0.4 of coming up heads. What is the probability that when flipped one hundred times it comes
inn [45]

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
