If the re-expressed regression line is ln y = 8.7 + 0.23x, what is the value of y when x is 12?
Sauron [17]

Answer:

y=11.46

Step-by-step explanation:

y = 8.7 + 0.23x \\ y = 8.7 + 0.23(12)

y = 8.7 + 0.23 \times 12 \\ y = 8.7 + 2.76

y = 11.46

to \: multiply \: 0.23 \times 12 \\ you \: convert \: the \: decimal

= 23 \ \times  12 \div 100 \\  = 276 \div 100

Please explain how to do this.
damaskus [11]

Step-by-step explanation:

let the eqn be y = mx + b.

m = 200/(900 - 700) = 1

sub (700, 0):

0 = 700 + b

b = -700

therefore eqn is y = x - 700

The number line shows the distance in meters of two birds, A and B, from a worm located at point X:
Svetlanka [38]

The image of the number line is missing, so i have attached it.

Answer:

5 metres

Step-by-step explanation:

From the attached image, we can see that point A is at -2.5 while point B is at 2.5.

Thus,distance between points A and B is; 2.5 - (-2.5). Where -2.5 is the additive inverse of 2.5.

Minus outside bracket when multiplied by minus inside the bracket will yield a positive sign.. Thus: distance = 2.5 + 2.5 = 5 m
