Answer:
y+4=-5/2(x-3)
Step-by-step explanation:
m=(y2-y1)/(x2-x1)
m=(6-(-4))/(-1-3)
m=(6+4)/-4
m=10/-4
m=-5/2
y-y1=m(x-x1)
y-(-4)=-5/2(x-3)
y+4=-5/2(x-3)

Answer:
Answer:
B
Step-by-step explanation:
First to find the sample mean
Xbar= summation x/n= 40/4= 10
The sample standard deviation is:
S= √summation(x-xbar)²/ n-1
=√6/3= 1.4142
The degrees of freedom
df= N-1= 4-1= 3
For 95% confidence level, critical value of t
t= 3.182
The 95% confidence interval is:
=Xbar plus or minus t' *8/√n
= 10 plus or minus 3.182(1.4142/√4)
= 10plus or minus 2.25
So 7.75 or 12.25
whatever% of anything is just (whatever/100) * anything.
so the socket set has a 40% off, what is 40% of 36? well, is just (40/100) * 36, or 14.4, that's the discount, so the sale price is 36 - 14.4, or 21.6.
plus the 8.25% taxation, what is 8.25% of 21.6? well, is just (8.25/100) * 21.6, or 1.782.
so the total price is 21.6 + 1.782, or 23.382, or about 23 bucks and 38 cents.
