Answer:
28
Step-by-step explanation:
2x + 7 = 4x - 7
14 = 2x
x = 7
BC = 4x = 4(7) = 28
1) 1ml % 6 marbles = about 0.17ml so the volume per marble is 0.17ml 2) 10-(0.17x4) = 9.32 so that is the original volume 3) then 9.32 + (0.17 x 13) = 11.53ml 4) it is linear because for every marble placed inside the cylinder the volume increases by about 0.17ml the slope means amount of marbles placed vs. volume in cylinder
Answer:
0.3573 = 35.7%
Step-by-step explanation:
We roll a pair of dice 10,000 times so the mean and standard deviation is,
μ = 10000/36 =277.7 σ = ![\sqrt{10000*\frac{35}{36^{2} } } =16.4](https://tex.z-dn.net/?f=%5Csqrt%7B10000%2A%5Cfrac%7B35%7D%7B36%5E%7B2%7D%20%20%7D%20%7D%20%3D16.4)
= (280 - 277.7)/16.4 = .14
= (300 - 277.7)/16.4 = 1.35
Probablity (range)
0.3573
Z(low)=0.14 0.555766357
Z(upper)=1.36 0.91304644

Answer: y = x - 1
Step-by-step explanation:
The yellow points are located at the points (1, 0) and (8, 7)
For a linear equation that pases trough the points (x1, y1) and (x2, y2), the slope is:
s = (y2 - y1)/(x2 - x1)
Then, for our equation, the slope is
s = (7-0)/(8-1) = 1
Then our linear equation is
y = 1*x + b
where b is the y-axis intercept.
To find b, we can use that when x = 1, y = 0
0 = 1*1 + b
b = -1
Then our equation is y = x - 1
