The y-term is -2y. We know this is the y-term because it is a multiple of the variable y and is not multiplied with any other variables.
A coefficient is a number that a variable is multiplied by. When there is a number followed by a variable, the number is the coefficient.
In this case, the coefficient of the y-term is -2. The coefficient is negative because 2y is being subtracted, meaning the 2 is negative rather than positive.
Hope this helps!
Answer:
y= 3/5x + 1
Step-by-step explanation:
Slope intercept form is modeled by the equation y=mx+b.
M = slope, while B = y-intercept.
The y-intercept in this scenario equals (0, 1) or just simply 1.
The slope equals 3/5. This can be found with rise/run or y/x.
Answer:
I guess you want the y intercept form is so the answer is:
y = 
x - 4
Step-by-step explanation:
3x - 2y = 8
subtract 3x from both sides
-2y = -3x + 8
divide -2 from both sides
y = x - 4
and done
Answer:
Step-by-step explanation:
(2-3)⁴ *4 - 9 + 3 = (-1)⁴ *4 - 9 + 3
= 1*4 - 9 +3
= 4 - 9 + 3
= - 5 + 3
= - 2
Answer:
We don´t have at 95% of confidence, evidence to reject the publisher´s claim
Step-by-step explanation:
Population mean p₀ = 58 % or p₀ = 0,58
Hypothesis Test:
Null Hypothesis H₀ p = p₀
Alternative Hypothesis Hₐ p < p₀
For a significance level α = 0,05 means that CI = 95 % or CI = 0,95
z(c) = - 1,64
MOE = z(c)* √(p*q)/n
p - p₀ / √(p*q)/n = z(s)
And that z(s) is in the acceptance region
|z(s)| < |z(c)|
|z(s)| < 1,64
Then if that so we fail to reject H₀ . We don´t have evidence to reject the publisher´s claim
