Answer:
No solutions
Step-by-step explanation:
5(x-2)=5x-7
5x-10 = 5x-7
When you try to solve this equation, you end up cancelling out the 5x on both sides, which means you cannot solve for x, so there are no solutions.
In conclusion, these are two parallel lines, since they have the same slope with different y intercepts.
Answer:
30 bracelets
Step-by-step explanation:
she could make 6 in 1 hour so 18 bracelets in 3 hours plus 12 bracelets in 2 hours which equals 30 bracelets.
6(3+2)=x
x=30
Solution :
Given :
Sample mean,
Sample size, n = 40
Standard deviation, s = 83.2
∴ The null hypothesis is
Alternate hypothesis is
Test statistic :
z = 0.813
Now at α = 0.05, for a right tailed,
Since, , we fail to reject the null hypothesis.
Answer:
Circle B has an area of 200.96 in².
Step-by-step explanation:
π = 3.14
radius of circle A = diameter of circle A/2
= 16 in/ 2 = 8 in.
Area = πr² = (3.14)(8²)
= (3.14)(64)
= 200.96 in²
The answer would be B -- 45
