Answer:
x=−16/7
Step-by-step explanation:
happy to help ya :)
R(7)=????
r(n)=0.009n s0 n=7
r(7)=0.009(7)
r(7)=0.063
So if there are 5 choices and only one is correct, there is a 1/5 chance of being correct. since there was 2 questions, you need to multiply 1/5 by 1/5 to get 2/25 of getting both questions correct.
i hope this helps!!
Your answer would be 3.4
Anything under 5 it stays the same and anything over 5 it goes up one
To solve an addition problem, you simply add one number to the other. For example,
If I want to add 4 to 5, I would write the equation 4 + 5 = 9.
To solve a subtraction problem, you simply take a number away from another. For example,
If I want to take 5 away from 9, I would write the equation 9 - 5 = 4.
Hope I helped! :)
