Answer:
Hello your question is incomplete attached below is the complete question
answer : 192.15 pounds
Step-by-step explanation:
Given :
weight = - 99.41 + 3.94*Height
R^2 = 0.81
SER = 10.2
<em><u>Determine the regression weight prediction</u></em>
Height of man = 74 inches
Hence : weight = - 99.41 + 3.94 * 74 = 192.15
therefore the regression weight prediction = 192.15 pounds
Answer:
3
Step-by-step explanation:
Answer:
f(x) = -4x + 80
Step-by-step explanation:
You are given two points,
(5, 60) and (10, 40)
in order to get the equation, let's use the form slope-intercept form
m = (y1 - y2) / (x1 - x2)
m = (60 - 40) / (5 - 10)
m = 20/-5
m = -4
Get the x intercept
y = mx + b
60 = (-4)(5) + b
b = 60+20
b = 80
so the equation is
y = -4x + 80
f(x) = -4x + 80
Answer B
Step-by-step explanation:
2x+1+14
Kiri walks : 4 km per week
0.5 × 5 + 0.75 × 2 = 2.5 + 1.5 = 4 km per week.
WHY?
Because 0.55 is close to 0.5 and 1.4 is closer to 1.5
