D. (x + y, 3x-2y) = (7,11)​
siniylev [52]

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

What happens to the probability of making a Type II​ error, beta​,as the level of​ significance, alpha​,​decreases? Why?
andrew-mc [135]

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.

HELP PLEASE I WILL MARK YOU AS A BRAINLIEST!!
stepan [7]

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.
