Formula for the Minimum Sample size n=(\frac{z}{E})^2\hat{p}\hat{q}

The least biased estimate for p and q is 1/2.

z_{\frac{\alpha }{2}}=z_{{0.01}{2}}=2.58

Thus

n=(\frac{2.58}{0.08})^2*0.5*0.5

n=260.015

n\approx260

Convert these unlike fractions to equivalent like fractions and add them. You must use the LCD to get the answer correct. If pos
Gnoma [55]

The converted fractions are 3/12 and 5/12 and the sum is 2/3

<h3>How to convert the fractions?</h3>

From the question, the fractions are given as

1/4 and 5/12

The denominators of these fractions are

4 and 12

So. we start by calculating the LCD of the denominators

So, we have

4 = 2* 2

12 = 2 * 2 * 3

This gives

LCD = 2 * 2 * 3

Evaluate

LCD = 12

This means that the common denominator must be 12

So, we have

1/4 and 5/12

Multiply 1/4 by 3/3

This gives

3/12 and 5/12

When the fractions are added, we have

3/12 + 5/12 = (3 + 5)/12

Evaluate

3/12 + 5/12 = 8/12

Reduce fraction

3/12 + 5/12 = 2/3

Hence, the sum of the fractions is 2/3

Jayden is blocking off several rooms in a hotel for guests coming to his wedding. The hotel can reserve small rooms that can hol
miv72 [106K]

Answer:

  • 12 large rooms
  • 8 small rooms

Step-by-step explanation:

If all were small rooms, 40 guests could be accommodated. Each large room accommodates 1 more guest, so there must be 52 -40 = 12 large rooms. The remaining 20 -12 = 8 rooms are small rooms.

Jayden reserved 12 large and 8 small rooms.

__

If you can't think without an equation, let x represent the number of large rooms. Then the number of guests accommodated is ...

  3x + 2(20-x) = 52

  x + 40 = 52

  x = 52 -40 = 12 . . . . . . .number of large rooms

  (20-x) = 20-12 = 8 . . . . number of small rooms
