A student researcher works at ski resort. For a student project, they would like to know whether the proportion of skiers on a p

articular day is about the same as the proportion of snowboarders. They take a stratified random sample, looking at each of the 3 chair lifts and randomly selecting every other chair of people to mark whether they are a skier (1) or a snowboarder (0). Which test is most appropriate to test whether the proportion of skiers is not 0.50?

Answer:

One sample test of proportions

Step-by-step explanation:

Which test is most appropriate to test whether the proportion of skiers is not 0.50?

Since the test says to test whether the proportion of skiers is not 0.50, then here we will be studying just only the promotion of skiers without the comparison with snowboarders.

We have been given an hypothesized promotion and the test says to test against this proportion, so the appropriate test to use here is the one sample test of proportions

Solve tan(3x)=1 if -pi≤x≤pi.
levacccp [35]
Tan(3x) = 1

x = (pi/4)/3 = pi/12 or (-3pi/4)/3 = -pi/4
Therefore, x = pi/12 or -pi/4

Describe 2 real world situation that could be modeled by a quadratic function
Naya [18.7K]

Solution:

1. Consider two trees which are 5 m apart. Suppose one tree is located at a distance of 45 m from my house and another tree is located 50 m from my house. Represent , distance of two trees from my house in terms of Quadratic function.

Solution:

Let location of my house when map of planet earth is drawn or on  globe=x

⇒(x-45)(x-50)=0

⇒ x² - 45 x - 50 x +45 × 50 =0

⇒ x² - 95 x + 2250=0

2. Suppose age of me and my brother is 6 and 10 years. The Product of  difference between age of me and my mother who is x years old and my brother and mother is 780.Find my mother's age.

Solution:  Age of my mother = x years

→(x-6) × (x-10)= 780,

if you will solve it , the value of x= 36 years
