Alex73 [517]

Answer:

a. A researcher wants to compare the hand–eye coordination of men and women. She finds a random sample of 100 men and 100 ​women, and measures their hand–eye coordination = paired samples

b. A researcher wants to know whether professors with tenure have fewer office hours than professors without tenure. She observes the number of office hours for professors with and without tenure. =  independent samples

Explanation:

Paired-samples t tests compare scores on two different variables but for the same group of cases; independent-samples t tests compare scores on the same variable but for two different groups of cases.

PLEASE HELP ME SOMEONE
n200080 [17]

Answer:

Option 2: 27 is the correct answer.

Step-by-step explanation:

Given functions are:

f(x) = x^2-2\\g(x) = 4f(x) - 1

As we can see that the function g(x) in written in terms of f(x), first of all we have to find g(x) by putting the value of f(x) in g(x)

So putting f(x) = x^2-2 in g(x)

g(x) = 4(x^2-2)-1\\= 4x^2-8-1\\=4x^2-9

As g(-3) has to be found, putting x=-3 in g(x)

g(-3) = 4(-3)^2-9\\= 4(9)-9\\=36-9\\=27

Hence

Option 2: 27 is the correct answer.

Determine if a triangle can be formed with the given lengths. If it can, classify it as acute,
lisabon 2012 [21]

Answer:

steps below

Step-by-step explanation:

1. It can be formed a triangle: sum of any two sides is greater than the 3rd side

2. It can't be an obtuse triangle: 5² + 7² = 74 < 10²

   the triangle is an obtuse-angled triangle if  the square of the longest side (c²) is greater than the sum of the square of other two sides (c²>a²+b²)

A group of people were asked if they had run a red light in the last year. 456 responded "yes", and 304 responded "no". Find the
Amiraneli [1.4K]

Answer:

The probability that if a person is chosen at random has run to red light in the last year is 60%.

Step-by-step explanation:

Since a group of people were asked if they had run a red light in the last year, and 456 responded "yes", and 304 responded "no", to find the probability that if a person is chosen at random, they have run a red light in the last year, the following calculation must be performed:

456 + 304 = 760

760 = 100

456 = X

456 x 100/760 = X

45600/760 = X

60 = X

Therefore, the probability that if a person is chosen at random has run to red light in the last year is 60%.
