11<br> The 7th term of Ap is 27 and the 12th term is 47.what is the sequence

inessss [21]

Answer:

3, 7, 11, 15, 19, 23, 27,.......

Step-by-step explanation:

Let the first term and the common difference of the AP be a and d respectively.

$a_7 = 27 .....(given)$

Therefore,

a + (7- 1) d = 27

a + 6d = 27

a = 27 - 6d...... (1)

$a _{12} = 47.....(given)$

Therefore,

a + (12 - 1) d = 47

a + 11d = 47......(2)

From equations (1) & (2)

27 - 6d + 11d = 47

24 + 5d = 47

5d = 47 - 27

5d = 20

d = 20/5

d = 4

Plug d = 4 in equation (1) we find:

a = 27 - 6*4

a = 27 - 24

a = 3

Therefore,

$a_1 = a = 3$

$a_2 = a_1 + d= 3 + 4 = 7$

$a_3 = a_2 + d= 7 + 4 = 11$

$a_4 = a_3 + d= 11 + 4 = 15$

$a_5 = a_4 + d= 15 + 4 = 19$

$a_6 = a_5 + d= 19 + 4 = 23$

$a_7 = a_6 + d= 23 + 4 = 27$

Thus, the sequence is: 3, 7, 11, 15, 19, 23, 27,.......

I need help I don’t understand this

Andrei [34K]

See the explanation

<h2>Explanation:</h2>

Hello! here we need to match the statements on the left-hand side to the reasons on the right-hand-side.

So this is as follows:

Statements: Reasons:

Segment Addition Postulate $AB+BC=AC$

Substitute the given values $5x+1+15=7x$

Simplify $5x+16=7x$

Subtract 5x from both sides $16=2x$

Divide both sides by 2 $16/2=2x/2$

Simplify $AC=7x$

Substitute 8 for x $AC=7(8)$

Simplify $AC=56$

So what we did here is to find the measure of segment AC by finding the x-value first. In other words, we have proven that AC = 56 by following logical arguments organized in an structured manner.

For a sample size of 115 and a population parameter of 0.1,what is the standard deviation of the normal curve that can be used t

Helga [31]

Answer:

A) 0.028

Step-by-step explanation:

Given:

Sample size, n = 115

Population parameter, p = 0.1

The X-Bin(n=155, p=0.1)

Required:

Find the standard deviation of the normal curve that can be used to approximate the binomial probability histogram.

To find the standard deviation, use the formula below:

$\sigma = \sqrt{\frac{p(1-p)}{n}}$

Substitute figures in the equation:

$\sigma = \sqrt{\frac{0.1(1 - 0.1)}{115}}$

$\sigma = \sqrt{\frac{0.1 * 0.9}{115}}$

$\sigma = \sqrt{\frac{0.09}{115}}$

$\sigma = \sqrt{7.826*10^-^4}$

$\sigma = 0.028$

The Standard deviation of the normal curve that can be used to approximate the binomial probability histogram is 0.028

Pavlova-9 [17]

Answer:

True

Step-by-step explanation:

We know Billy is paid $32 for 8 hours of work.

All we have to do is divide 32 by 8 to see if whether he gets paid 4 dollars an hour,

32/8

==> 4

This is true
