The average age of all students at a certain college is 22 years and the standard deviation is 2 years. What is the probability
Marianna [84]

Answer:

The probability that the average age of a randomly selected sample of 100 students will be less than 21.8 years is 0.159

Step-by-step explanation:

According to the given data we have the following:

mean = μ= 22

standard deviation = σ = 2

n = 100

μx = 22

σx=σ/√n=2/√100=0.2

Therefore, P( x < 21.8)=P(x-μx)/σx<(21.8-22)/0.2

=P(z<-1)

= 0.159

The probability that the average age of a randomly selected sample of 100 students will be less than 21.8 years is 0.159

Nth term of this sequence please 18, 16, 14, 12
Annette [7]

Answer:

\boxed{\sf -2n+20}

Step-by-step explanation:

Let’s find the common difference.

The common difference can be found by subtracting a term in the sequence with the previous term.

\sf d=16-18\\d=-2

Apply formula for the \sf n^{th} term of an arithmetic sequence.

\sf a_n=a_1+dn-d

\sf a_1 is the first term of the sequence.

\sf d is the common difference.

\sf a_n=18+-2n-(-2)

\sf a_n=18+-2n+2

\sf a_n=-2n+20

1 over 4a = 2 over 3. Which of the following equals a in this equation?
dlinn [17]

Answer:

3/8

Step-by-step explanation:

The equation is given as:

1/4*a=2/3

We can simply the equation by getting rid of the denominators which is 4a and 3. Therefore we can multiply both sides with 3*4*a:

(1/4*a)3*4*a=(2/3)*3*4*a

On the left hand side 4a cancels with 4a and on the right hand side 3 cancels with 3. We are left with:

3=2*4*a

∴ After simplying

a=3/8
