y+z=10

x+z=8

x+y=12

(y+z)-(x+z)=10-8

y-x=2

y-x=2

y+x=12

solve simultaneously

x=5, y=7

then substitute to get z=3

hence xyz=573

In this scatterplot the individuals are states. The variable "cig" is the number of cigarettes sold per person in the state in 1
Ipatiy [6.2K]

Answer:

e= -5.41

Step-by-step explanation:

Hello!

In linear regression, a residual value is a distance between the observed values and the regression line.

The residual value (e) is calculated as the difference between the observed value (Y) and the predicted value (^Y).

e= Y - ^Y

e= 15.92 - 21.33 = -5.41

I hope it helps!

Can someone help me on letters B and C?
skelet666 [1.2K]

Step-by-step explanation:

B.

if he is just talking about the length than it is,

4(13x + 8)

of he is talking about overall length he swam than,

4(13x + 8) + 3(7x - 2)

c.

if x = 12

than

perimeter = 2l + 2b

so, after inserting the values we got,

→ 2[13(12) + 8] + 2[7(12) - 2]

→ 2 (156 + 8) + 2(84 - 2)

→ 2 × 164 + 2 × 82

→ 328 + 164

→ 492 ft. ← perimeter

and yeah, according to me

a is wrong as,

formula of perimeter = 2l + 2b or 2(l+b)

so, the answer should be,

2(13x + 8) + 2(7x - 2) or 2 [ (13x + 8) + (7x - 2)
