The answer is Demographic data

The researcher includes the following material in a research report: The seven males varied in age from 32 to 45 (M = 38), had a high school education (two had high school diplomas, one had an associate degree, three had an undergraduate degree, and one had a master's degree), and had yearly incomes ranging from $20,000 to $100,000 (M = $52,000). Demographic data refers to information on the characteristics of the individuals being investigated.

What is Demographic data?

  • Demographic analysis is the examination of a population's characteristics such as age, ethnicity, and gender.
  • Demographic data is a statistical representation of socioeconomic information such as employment, education, income, marriage rates, birth and death rates, and so on.
  • Age, race, ethnicity, gender, marital status, income, education, and occupation are some examples of demographic information. With survey questions, you may quickly and efficiently collect this sort of information.

A pancake recipe requires 1 & 2/3 cups of flour to make 20 pancakes and you have 9 cups of flour. How many pancakes can you
wolverine [178]

Answer: 108 pancakes

Step-by-step explanation:

if you make 20 pancakes with  1 and 2/3 of flour,

with 9 cups you will make

(20*9)/ 1 &2/3

1  2/3= 5/3 we enter the whole in the fraction

(180)/(5/3)= 180*3/5=108 pancakes

Find the measure of angle 1
nikklg [1K]

Answer:

Angle 1, 2, 4 = 45 degrees

Step-by-step explanation:

2x+15 = x+30

-15 both sides

2x = x+15

-x both sides

x = 15

Plug x = 15 into x+30 or 2x+15

15+30 = 45

2(15)+15 = 45

Which quadratic relation has a y-intercept of 8?
Tpy6a [65]

Answer:

y = 0.5 (x^2 -2x + 16) has a y-intercept of 8.

Step-by-step explanation:

The x-coordinate of every y-intercept is zero.  To determine which of the four quadratics given here has a y-intercept of 8, we need only substitute 0 for x in each; if the result is 8, we've found the desired quadratic.

O y = 0.5(x + 2)(x + 4) becomes y = 0.5(2)(4) = 4 (reject this answer)

O y = 0.5 (x - 2)(x + 8) becomes y = 0.5(-2)(8) = -8 (reject)

O y = 0.5(x2 -2x - 16) becomes y = 0.5(-16) = -8 (reject)

<em>O y = 0.5 (x2 -2x + 16) becomes y = 0.5(16) = 8 This is correct; that '8' represents the y-intercept (0, 8).</em>

What is the greatest common factor of 48, 24, and 45?
pshichka [43]

Answer:

3

Step-by-step explanation:

Let's write the factors:

48's factors are = 1, 2, 3, 4, 6, 8, 12, 16, 24 and 48.

24's factors are = 1, 2, 3, 4, 6, 8, 12, 24.

45's factors are =1, 3, 5, 9, 15 and 45.

The greatest number that is in all three of these lists of factors is 3!

So, 3 is the greatest common factor between all three numbers!

Trucks in a delivery fleet travel a mean of 120 miles per day with a standard deviation of 18 miles per day. The mileage per day
kvv77 [185]

The probability that a truck drives between 150 and 156 miles in a day is 0.0247. Using the standard normal distribution table, the required probability is calculated.

<h3>How to calculate the probability distribution?</h3>

The formula for calculating the probability distribution for a random variable X, Z-score is calculated. I.e.,

Z = (X - μ)/σ

Where X - random variable; μ - mean; σ - standard deviation;

Then the probability is calculated by P(Z < x), using the values from the distribution table.

<h3>Calculation:</h3>

The given data has the mean μ = 120 and the standard deviation σ = 18

Z- score for X =150:

Z = (150 - 120)/18

   = 1.67

Z - score for X = 156:

Z = (156 - 120)/18

  = 2

So, the probability distribution over these scores is

P(150 < X < 156) = P(1.67 < Z < 2)

⇒ P(Z < 2) - P(Z < 1.67)

From the standard distribution table,

P(Z < 2) = 0.97725 and P(Z < 1.67) = 0.95254

On substituting,

P(150 < X < 156) = 0.97725 - 0.95254 = 0.02471

Rounding off to four decimal places,

P(150 < X < 156) = 0.0247

Thus, the required probability is 0.0247.
