Answer:
30.0
Step-by-step explanation:
Given our data is normally distribute with 
and 
-Top 7% is given by find the z-value corresponding to p=(1-0.07)=0.93
-We substitute our values in the equation below;
Hence, the minimum score required for the scholarship is 30.0
The sale price of 3 bottles of shampoo is 3s and the regular price is 3r. The amount of money you save will only come in when you buy 3. The cost you save is the difference between the regular price and the sale price. The equation is therefore,
c = 3r - 3s
Answer:
x=4
Step-by-step explanation:
-5x+5-x+1=-18
combine like terms
-6x+6=-18
subtract 6 from both sides
-6x=-24
divide both sides by -6
x=4
Answer:
Solution given:
y=6/7x+7
Comparing above equation with y=mx+c
we get
m=6/7
a What is the slope of a line parallel to it?
Since for parallel slope are equal ,
slope will be 6/7.
b What is the slope of a line perpendicular to it?
Since for perpendicular line slope is reciprocal to another line but negative so
slope of line is-7/6.
