Answer:
1 3.3y
Step-by-step explanation:
Bet...but you really need to learn how to to this bc you use this in all types of math
All you have to do is distribute then combine like terms

You’re given that m=7 (slope is 7), so setup the slope-intercept form with that info: y = 7x + b.
Now you need to find b. Plug in (3,11) for x and y, x=3 and y=11.
11 = 7*3 + b
Notice the only variable left is b, so you’ll find b this way.
11 = 21 + b and then subtract 21 from both sides:
11 - 21 = b
-10 = b
Plug that back into the equation and you have y = 7x -10
Answer:
f and b
Step-by-step explanation:
if you put them in y-intercept form, both slopes are 3
In b. it's easy to see that 3x has a slope of 3.
In f. it's not so obvious. Just solve for y or use the shortcut m = -a/b where a is the coefficient of x and b is the coeff of y.
hence -(6/-2)=3
Answer:
Solution: given that
n = 38
p = 2/5 = 0.4 q = 1-p = 1-0.4 = 0.6
standard deviation = sqrt(n*p*q)
sqrt(38*0.4*0.6) = 3.0199
