Answer:
y= 1/4x+5
Step-by-step explanation:
y=mx+c
to calculate gradient: change in y/change in x
-3/-12 = 0.25
y = 1/4x+c
4 * 1/4 = 1
6-1 = 5
c= 5
Totally:
y= 1/4x+5
I would answer but I’m in 6th grade and I don’t know how to
Answer: 0.701
Step-by-step explanation:
Formula :
, where
significance level ,
Population standard deviation, n= sample size.
As per given, n= 22
![\sigma = 2](https://tex.z-dn.net/?f=%5Csigma%20%3D%202)
Critical z- value for 90% confidence level : ![z_{\alpha/2}=1.645](https://tex.z-dn.net/?f=z_%7B%5Calpha%2F2%7D%3D1.645)
Then,
![EBM =(1.645)\dfrac{2}{\sqrt{22}}\\\\=(1.645)\dfrac{2}{4.690416}\\\\\approx0.701](https://tex.z-dn.net/?f=EBM%20%3D%281.645%29%5Cdfrac%7B2%7D%7B%5Csqrt%7B22%7D%7D%5C%5C%5C%5C%3D%281.645%29%5Cdfrac%7B2%7D%7B4.690416%7D%5C%5C%5C%5C%5Capprox0.701)
Hence , error bound (EBM) of the confidence interval with a 90% confidence level= ± 0.701
In a trapazoid the diagonals are the same so therefore the two equations equal echother
3x+7=5x-11 solve for x by combining like terms
18=2x then divide to unto multiplication
9=x
9 is the value of x
I hope I've helped!
We need slope of all lines ?
