I am sure u have to separate the number with their variables so (4x) (2y -y ) (40+10)
Remember that you have to remove the brackets and u should have 4x - 1y + 50 then 4\4 and 50/4 = four cancles out 4 so we have 1y + 12.5 divide each by one one cancles out 1 = 12.5 round it up to 13 but I suggest u check this with anyone else you can but if my math is correct it should be the closest answer

Which combination of transformations can you use to show that one shape is congruent to another? dilations and reflections/ refl
Ganezh [65]
The correct answer to this is:
ROTATIONS AND TRANSLATIONS

Reflection and rotation can also be used but since their both grouped with dilations, they can't be used. When dilation is used, the size of the shape is changed and congruence won't be possible anymore . That's why the answer is the first option.

You measure 25 turtles' weights, and find they have a mean weight of 31 ounces. Assume the population standard deviation is 12.8
Firlakuza [10]

Answer:

Margin of error = 4.21 ounces  

Step-by-step explanation:

According to the Question,

  • Given That, You measure 25 turtles' weights, and find they have a mean weight of 31 ounces. Assume the population standard deviation is 12.8 ounces

Therefore, Sample mean = 31 ounces  ,  Sample size(n) = 25 , Alpha(α) = 0.10 & Population standard deviation(σ) = 12.8 ounces

  • Thus, Margin of error  = Z_{critical} × σ / √n  (Z_{critical} at α=.010 is 1.645)

Putting The Values, We get

1.645 × (12.8 / √25 ) ⇒ 4.2112 ≈ 4.21

Thus, the maximum margin of error associated with a 90% confidence interval for the true population mean turtle weight is 4.21 ounces
