Answer:a right angle

Step-by-step explanation: The rectangle has right angles. When the angles are diagonals the angles are bisected therefore what was 90 is now 90/2=45. A triangle of any kind should equal 180 so lets check it 90+45+45=180.

A: y=1/3x+5

B: y=-2x+9

C: y=-3

D:y=2x+9

E: y=-10x+80

F:y=x-2

#1 rodney's error for

y=30x+10 is that he started off at 30 but he had to start off at 10 so it starts at (0,10) (1,40) (2,70) and keep going on by adding one to the x value and 30 to the y value

#2 rodneys error for

y=-1/2x+5 is that he went up by 1/2 instead of going down. it's a negative 1/2 so he had to go down

#3 Rodneys error for

y=x-2 is that he didn't start at (0.-2)

A juice drink filling machine, when in perfect adjustment, fills the bottles with 12 ounces of drink on an average. Any overfill

ozzi

Answer:

d. The average is equal to 12 ounces.

Step-by-step explanation:

In this problem, the drink filling machine must be perfectly calibrated at 12 ounces since it needs to be shut down in cases of overfilling (mean > 12 ounces) and underfilling (mean < 12 ounces). Therefore, the correct approach would be to test if the mean is 12 ounces and the correct set of hypothesis would be:

$H_0:\mu=12\\H_a:\mu\neq 12$

The correct alternative is d. The average is equal to 12 ounces.
