Answer:
A quadratic equation
....[1] where, a, b and c are coefficient.
Then the solution is given by:
....[2]
As per the statement:
Given the equation:
![x^2=5-x](https://tex.z-dn.net/?f=x%5E2%3D5-x)
⇒![x^2+x-5 = 0](https://tex.z-dn.net/?f=x%5E2%2Bx-5%20%3D%200)
On comparing with [1] we have;
a =1, b = 1 and c = -5
Then substitute these in [2] we have;
![x = \frac{-1 \pm \sqrt{1^2-4(1)(-5)}}{2(1)} =\frac{-1 \pm \sqrt{1+20}}{2} =\frac{-1 \pm \sqrt{21}}{2}](https://tex.z-dn.net/?f=x%20%3D%20%5Cfrac%7B-1%20%5Cpm%20%5Csqrt%7B1%5E2-4%281%29%28-5%29%7D%7D%7B2%281%29%7D%20%3D%5Cfrac%7B-1%20%5Cpm%20%5Csqrt%7B1%2B20%7D%7D%7B2%7D%20%3D%5Cfrac%7B-1%20%5Cpm%20%5Csqrt%7B21%7D%7D%7B2%7D)
Therefore, the values of x are:
,
First do parenthesis
12.3*108=1328.4
1.06*10-7= 3.6
multiply them together
1328.4*3.6=4,782.24
So 4,782.24 is the answer
Each section of the tree diagram (in this case the branches that say vanilla chocolate and strawberry) must add up to 1
so to answer you should do 0.45+0.35= 0.8
then 1-0.8 =0.2
so Z is 0.2
Answer:
the answer is below
Step-by-step explanation:
The equation of the line will have the form y=Ax+B where A, B are constants to be found. Since we want the slope to be 3 we have that A=3. Since we want the line to pass through the point (6,-8) we have that -8=3(6)+B or B=-26. Thus, the equation of the line is y=3x-26.
Step-by-step explanation:
The probability of choosing a digestive will be 0.5/2
The probability of choosing a chocolate will be 1.5/2
