The selling price for houses in a neighborhood in West Richland, WA have an approximately normal distribution with a mean sellin
Liula [17]

The probability that the average selling price of the 35 homes will be within $2000 of the true mean is 0.5753

First, we need to find the z-score and this is expressed according to the formula;

z=\dfrac{x-\mu}{\sigma}

x is the sample space

\mu is the mean value

\sigma is the standard deviation

Given the following parameters

Mean = $275,000

Standard deviation = $10,500

If the true mean is $273,000, then;

z=\dfrac{273,000-275000}{10,500} \\z = \frac{-2000}{10500}\\z= -0.1905

If the true mean is $277,000

z=\dfrac{277,000-275000}{10,500} \\z = \frac{2000}{10500}\\z= 0.1905

This means that the z-score is between -0.1095 and 0.1095

Pr( -0.1095 ≤ z ≤ 0.1095)

According to the z table, the probability that the average selling price of the 35 homes will be within $2000 of the true mean is 0.5753

Find c to complete the perfect trinomial<br><br> x2 + 4x + c
sladkih [1.3K]

Answer:

4

Step-by-step explanation:

I assume that is supposed to be x squared. A perfect trinomial is the product of a perfect square, (x times a number) squared. With these trinomials, you can look at them as: ax squared times bx + c. When a is 1, the fastest way to get c to make a perfect square is to divide b by 2. In this case, it's 4/2 = 2. The last step is to square that number. 2 squared = 4.

Plz help me with dis its one question
tatiyna

Answer:

Alix does. See below.

Step-by-step explanation:

Givens

<em><u>Jenny</u></em>

  • b1 = 90 cm
  • b2 = 80 cm
  • height = 23 cm

<em><u>Alex</u></em>

  • b1 = 90 cm
  • b2 = 70 cm
  • height = 27 cm

Formula

For both territories the answer is based on the formula

  • Area = (b1 + b2)*h/2

Solution

<em><u>Jenny</u></em>

  • Area = (90 + 80)23/2
  • Area = 170 * 23 / 2
  • Area = 85 * 23
  • Area = 1955 units.

<em><u>Alex</u></em>

  • Area = (70 + 90)*27/2
  • Area = 160*27 / 2
  • Area = 80* 27
  • Area = 2160

Alix does by 205 cm
