Answer:
= 7.5x-8
Step-by-step explanation:
Total cost = cost per yard * yard of fabric - coupon
total cost = 7.5 x - 8
y = 7.5x-8
Answer:
31.1% increase
Step-by-step explanation:
% increase= 100 X (final-initial)/initial
Answer:
X : ___ 0 ____ 1 _____ 2 ______ 3
P(X) : _ 6/15 __ 5/15__ 3/15 ____ 1/15
Step-by-step explanation:
From the data, to produce a probability distribution for the data :
X : number of times blood is drawn ;
P(x) : probability that blood is drawn at X times
Hence, the probability distribution table for the data Given goes thus :
X : ___ 0 ____ 1 _____ 2 ______ 3
P(X) : _ 6/15 __ 5/15__ 3/15 ____ 1/15
Probability that blood is drawn 0 times = 6/15
Probability that blood is drawn 1 time = 5/15
Probability that blood is drawn 2 times = 3/15
Probability that blood is drawn 3 times = 1/15
(6/15 + 5/15 + 3/15 + 1/15) = 1
Answer:
x = 5
Step-by-step explanation:
First you distribute
9x - 21 = 24
Add 21 to both sides
9x = 45
Divide both sides by 9
x = 5
Answer:
20.6
Step-by-step explanation:
Since the diameter of each circle is 4, the dimensions of the rectangle is 8x12
The area of the whole rectangle is 96
Now we need to find the area of the circles
The area of 1 circle is 
...
So the area of all 6 circles is 12.56*6= 75.39...
So to find the area of yellow you have to subract the area of circle from the overall area of the rectangle
96-75.4=20.6
