There are currently 3 people signed up for the debate club. The school will not recognize the club officially until it has more than 5 members. Which of the following graphs includes the possible values for the number of people who still need to sign up to make the club "official?" Number line with closed circle on 2 and shading to the left. Number line with closed circle on 2 and shading to the right. Number line with open circle on 2 and shading to the left. Number line with open circle on 2 and shading to the right. Question 2(Multiple Choice Worth 4 points) (07.06) A retirement community has a sign at its main entrance that says "Residents over the age of 55 welcome." Which of the following inequalities best represents the age of residents welcome in the retirement community? z > 55 z 9 a 12 k ≤ 12 k ≥ 12 pls answer all bc I'm giving a lot of points

1. Number line with open circle on 2 and shading to the right.

2. z > 55

Step-by-step explanation:

Question 1

It is > 2, so is the number line with open circle on 2 and shaded to the right

Question 2

over the age of 55  ⇔ z > 55

answer: idk

step-by-step explanation:

the largest number of the four options is 1.8 x 10-2

you have it in scientific notation.

1.80 x 10-6   = 0.00000180

1.80 x 10-4   = 0.000180 (bigger, or "less small", than the former one)

so

1.8 x 10-2       = 0.0180. as you see. the "less small", or the biggest one of them all.

as you have negative exponent, it means you are dividing 1.8 by 100 (i.e. moving the dot towards left, two times).

if you had positive exponent for the scientific notation, power of tenths, you would be multiplying times 100 (moving the dot towards right) as below:

1.8 x (10)2 = 180

so. if you have negative exponent in scientific notation, move the dot toward left. if it is positive, toward right as many times the exponent tells you.
