Answer:
Attached file describes the set of 16 possible orders for this experiment
Step-by-step explanation:
<em>Please see attached file for tree diagram</em>
We have to build a tree diagram to represent this solution.
At level 1 we have 2 options: automatic transmission or standard transmission
At level 2, each of the 2 level-1 options split into 2 new options: with air conditioning and without air conditioning. Therefore, at this level, we have 2 x 2 = 4 options.
And, at level 3, each of the 4 level-2 options split into 4 new color options: red, blue, black or white. Therefore, at this final level, we have 4 x 4 = 16 possible orders
Please see the attached tree diagram for a better description of this set of 16 possible orders
Solve the equation for x by finding a, b, and c of the quadratic then applying the quadratic formula.
x=1+or- i square root of 22
Answer:8
Step-by-step explanation: Since the opposing way of solving is division, you divide 72 into 9 and you get 8.
Answer:
You're doing it right. 25^4 would be 25 x 25 x 25 x 25 which equals to 390,625. Hope this helps :)))
X=number of boys.
y=number of girls.
we suggest this system of equation
x/y=9/7
x=y+116
We solve this system of equation by substitution method.
(y+116)/y=9/7
7(y+116)=9y
7y+812=9y
9y-7y=812
2y=812
y=812/2=406
x=y+116
x=406+116=522
answer: At the school there are 522 boys and 406 girls.
to chek.
522/406=1.2857...
9/7=1.2857...
The number of boys (522) is equal to 406+116=522.
