Answer:
x = 5, y =2
Step-by-step explanation:
I guess the question is saying x+y = 7 and 3x-2y = 11?
then there are multiple ways but
I will multiply the first one by 2 so 2x+2y = 14
you add the equations to get 5x = 25 so x = 5 plug x into the first equation you get y = 2
if that isn't what the question means just comment and I'll change it
18/97 to the nearest hundreth is 0.18
Answer:
Lowering the level of significance, α increases the probability of making a Type II error, β.
Step-by-step explanation:
Lowering the level of significance, α increases the probability of making a Type II error, β.
This is because the region of acceptance becomes bigger, and it makes it less likely for one to reject a null hypothesis, when it is false, the type II error.
Answer:
Bike, family vehicle, bus
Step-by-step explanation:
Since the bike fraction is 12/100 that will be the least.
Then, the family vehicle fraction is 19/100 that will be in the middle.
Lastly, the bus fraction is 5/20. So, you multiply the numerator and denominator by 5 to get 25/100, so that will be the greatest.
Here is the answer I hope it helps
