Answer:
ive tried working it out and i couldnt seem to get it but my best guess would be C OR B
Step-by-step explanation:
Answer:
the answer will be y=1
Step-by-step explanation:
If you plug in (3x-5) in for y in the 6x+3y=15, you will get 6x+9x-15=15. Add the like terms (6x+9x) and get 15x. Bring the -15=15 down. Add 15 to the other 15 on the other side of the equal sign, bring 15x down and then divide 15 by 30 and get x=2. Plug in 2 for x in the (3x-5) equation, then solve and the answer will be y=1.
Answer:
a) 3.16
Step-by-step explanation:
<u><em>Explanation:-</em></u>
<em>Given sample size 'n' =4</em>
mean of x⁻ = ∑x / n
= 
x⁻ = 16
Given data
x 13 14 17 20
x - x⁻ -3 -2 1 4
(x-x⁻)² 9 4 1 16
∑(x-x⁻)² = 9 + 4 + 1 +16 =30
The sample Variance
S² = ∑(x-x⁻)²/n-1
<em>The standard deviation of the sample </em>
<em> S = √10 = 3.1622 ≅3.16</em>
A) Dependent Variable = Sue's Earning
Independent Variable = Number of hours she work
Y = 6x
B) When, x = 1, y = 6(1) = 6,
when x = 2, y = 6(2) = 12
when x = 3, y = 6(3) = 18
Ordered pairs would be: (1, 6), (2, 12), (3, 18)
C) Equation would be: Y = 6x
Where, y = Earning
x = number of hours
Hope this helps!
