Answer:
0.249874
Step-by-step explanation:
After every 4 digits, n squared is divisible by 8 so we have 1989/4= 497 numbers divisible by 4 after squaring
probability n=497/1989= 0.249874
Probability n=0.249874
$57.50-$8= $49.50 because she already has $8 so she doesn't need to save those and then
$49.50÷ $4.50=11 weeks and u do this to give u the number of weeks so
she would have to save $4.50 for 11 weeks
so the answer is h) 11 weeks
Answer:
There is no x value, as there is no solution
Step-by-step explanation:
we have
2x+y=1
Isolate the variable y
y=-2x+1 -----> equation A
4x+2y=-1 ---> equation B
Solve the system of equations by substitution
Substitute the equation A in the equation B and solve for x
4x+2(-2x+1)=-1
4x-4x+2=-1
2=-1 ------> is not true
therefore
The system has no solution
Equation A and equation B are parallel lines with different y-intercepts
