An agent for a real estate company wanted to predict the monthly rent for apartments based on the size of the apartment. the data for a sample of 25 apartments is available below. perform a t test for the slope to determine if a significant linear relationship between the size and the rent exists. a. at the 0.05 level of significance, is there evidence of a linear relationship between the size of the apartment and the monthly rent?

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.

60: 45 =12: 9 =4: 3 so the answer is 4: 3

i think the answer is a p = 78

step-by-step explanation:

there are 6 sides of a hexagon, multiply 13 x 6

answer: 24

step-by-step explanation:

7x2=14

5x2=10

10+14=24
