Answer:
7mn
Step-by-step explanation:
because 7 goes into both. but there is only one letter in each if you took more you would be in debt which you can't do with gcf
Answer:
Option b
Step-by-step explanation:
Given that the time that a skier takes on a downhill course has a normal distribution with a mean of 12.3 minutes and standard deviation of 0.4 minutes.
If X is the time that the skier takes then
X is N(12.3,0.4)
To convert this to Z score we can use the following
![z=\frac{x-12.3}{0.4}](https://tex.z-dn.net/?f=z%3D%5Cfrac%7Bx-12.3%7D%7B0.4%7D)
The probability that on a random run the skier takes between 12.1 and 12.5 minutes
=![P(12.1](https://tex.z-dn.net/?f=P%2812.1%3CX%3C12.5%29%5C%5C%3D%20P%28%7Cx-12.3%7C%3C0.2%29%5C%5C%3DP%28%7Cz%7C%3C0.5%29%5C%5C)
=0.383
Option b is right.
M = y2 - y1/x2 - x1
m = 4 — -4/6 - 8
m = 8/-2
m = 4/-1
m = -4
Parallel slopes are the same
m = -4
b = ?
Replace x and y values of the point into slope intercept formula
y = mx + b
-9 = -4(2) + b
-9 = -8 + b
-9 + 8 = b
b = -1
Write final equation
y = -4x - 1
Equation 1
Subtracting 5 from both sides we have
|2x - 3| = -1 - Since an absolute values must be positive this equation has no solutions.
Equation 2:-
|5x + 3| - 10 = 3
|5x + 3| = 13
either 5x + 3 = 13 or 5x + 3 = -13
so x = 2 or x = -16/5 = -3.2
The correct choice is B
All you have to do is addition. 2+5+4=11. Or you can break it down and go 2+5=7 and then 7+4=11. Or 5+4=9 then 9+2=11. Or 4+2=6 then 6+5=11.
