Answer:

The percent of people, who either lives or eats on campus is 34 %.

Step-by-step explanation:

Let the total number of people be 100.

<em>Let set A be people who live in campus =</em><em> 56</em>

<em>Let set B be people who participate in meal = </em><em>62</em>

<em>Let set C(A∩B) be people who do both = </em><em>42</em>

According to set theory,

(A∪B) = A + B - (A∩B) = 56 + 62 - 42 = 76

Then either lives or eats is given by,

= (A∪B)-(A∩B) = 76 - 42 = 34

Thus, the percent of people, who either lives or eats on campus is 34 %.

If Professor Wilson found that the test scores of his students had a variance of 4.4, what is the standard deviation? Type a num
malfutka [58]

Answer:

The standard deviation will be: 2.1        

Step-by-step explanation:

We know that standard deviation is basically the square root of variance.

Using the formula to calculate the standard deviation

s=\sqrt{s^2}

As

  • The variance =  s² = 4.4

so the standard deviation can be calculated as:

standard deviation =\sqrt{s^2}

                                 =\sqrt{\left(4.4\right)^}

                                  =2.1

Therefore, the standard deviation will be: 2.1

Write down the first three terms of the sequence whose nth term is given by 2n-5
likoan [24]

Answer:

- 3, - 1, 1

Step-by-step explanation:

To find the first 3 terms substitute n = 1, 2, 3 into the formula

a₁ = 2(1) - 5 = 2 - 5 = - 3

a₂ = 2(2) - 5 = 4 - 5 = - 1

a₃ = 2(3) - 5 = 6 - 5 = 1

The first 3 terms are - 3, - 1, 1
