You would do 0.25x (x is the unknown total number)=19. It is because of is a multiply sign, so 0.25*x=19. Divide both sides by 0.25 and you get 76 as your answer.
To get the probability that at least 8 of the words on the test are words that students know we need to do the following calculations.
<span>=[C(16,8)*C(10,2) + C(16,9)*C(10,1) + C(16,10)*C(10,0)] / C(26,10)
</span>
=0.132
Hey there! :)
When teachers ask you for the standard form in math, they are asking you to find the simplest form an equation with variables can be in.
Ax + By = C
Example : put y=2x -3 into standard form.
Subtract 2x from both sides.
-2x + y = -3 —> standard form.
Hope this helped! :)
Answer is 8 because you divide 30 by 5 then you get 6 and when you get 6 you add 2 and the answer is 8
Answer:
Exact form : - 1/5
Decimal form : -0.2
Step-by-step explanation: Substitute the value of the variable into the equation and then simplify.
Hope this helps you out. If not, comment and let me know. Good luck, mate! ☺
