Answer:
The required equation is:
Step-by-step explanation:
We need to find equation from the table given
x f(x)
3 -5
7 -2
11 1
15 4
We can write equation in the form of
where m is slope and b is y-intercept.
Finding Slope
We can used the slope formula to find slope:
From the table we have:
Putting values and finding slope
So, we get slope
Now, finding y-intercept
Using the slope and point (3,-5) we can find y-intercept
The y-intercept is
So, the equation having slope and y-intercept will be:
The required equation is:
Answer:
Step-by-step explanation:
x+y=10
x=10-y
x=10-5
x=5
3y= -3x+30
3(10-y)= -3(10-y)+30
30-3y= -30+3y+30
30+30-30=6y
30=6y
y=5
Divide to find the unit rate:
5.25 acres
---------------- = 1.1666... acres/day, or 1 1/6 acres/day.
4.5 days
Answer:
- Initial amount of the material is 67 kg
- Hal-life is 83 hours
<u>The required equation is:</u>
- m(x) = 67 * , where m- remaining amount of the radioactive material, x - number of hours
<u>After 5 hours the material remains:</u>
- m(5) = 67 * = 64.260 (rounded)
The correct answer for the question that is being presented above is this one:
We want to pull 11 (this means not including 12) or less from the bag and there are 100 possibilities
= 11/100
So the probability is <span>11/100</span>
