-57 if you keep following the pattern
The length of HI IS 3 since 9-6 is 3
Answer:
0.081,0.2621,0.645,0.919
Step-by-step explanation:
Let X be the average speed of a car driving down freeway
Given that X is normal with mean as 70mph with a standard deviation of 5mph.
To convert to Z score we do
a) the probability that a randomly selected car is driving more than 77mph
b) probability that a randomly selected car is driving between 65 and 69 mph
= 
c) the probability that a randonly selected car is driving between 67 and 77mph
=
d) the probability that a randomly selected car is driving less than 77mph
Answer:
$750
Step-by-step explanation:
We can set up the equation 30x + 50y = z where x = the amount of small dogs, y = the amount of big dogs, and z = the total.
After plugging in the x and y values to solve for z, we are left with the following equation:
30(15) + 50(6) = 750
Answer:
Step-by-step explanation:in standard form y= ax+b
-4y = -3x+28
4y =3x-28
or y= 3/4 x -7
So a= 3/4 = slope and -7 is y intercept ( parallel lines have same slope)
Equation 3 is
y= 3/4x-2
which also has slope = 3/4 and y intercept = -2
Parallel lines have same slope
Similarly a perpendicular line will have slope of - 1/a
For equation
y= ax+b
Perpendicular line is
y=( -1/a) x +c
