7(3-x)+1 .. first you're going to distribute
21-7x+1 .. then combine like terms
22-7x .. subtract 22 from both sides to get the variable X alone.
-7x=-22
x=3.14
Answer:
Step-by-step explanation:
Represent Green with G
So,
Required
Determine the probability that 10 out of 16 prefer green
This question is an illustration of binomial distribution and will be solved using the following binomial distribution formula.
In this case:
-- number of people
-- those that prefer green
So, the expression becomes:
Substitute 50% for G (Express as decimal)
Apply law of indices
Solve 16C10
<em>Hence, the required probability is 0.1222</em>
3000 grams because 2 kilograms is 2000 grams and 3000 is greater than 2000
Look at intersecting points of line on x- and y-axis.
The points would be: (8,0) & (0,4)
formula of slope = (y2-y1) / (x2-x1)
(4-0)/(0-8) = -4/8 = -1/2.
Answer:
Step-by-step explanation:
to find the inverse first switch the x and y
y=log(x+3) inverse is x=log(y+3)
then change to exponential form to solve
turns to
a is 10
b is y+3
c is x
subtract 3 from both sides
