Answer:
8.5 bags are needed.
Step-by-step explanation:
Given : Number of bags needed 

To Find : how many bags he needs?
Solution :



Now we are given that Number of bags needed 
Substitute the value of x


Hence 8.5 bags are needed.
Answer: b. 0.8413
Step-by-step explanation:
Given : The average time taken to complete an exam, X, follows a normal probability distribution with
and
.
Then, the probability that a randomly chosen student will take more than 30 minutes to complete the exam will be :-
[using z-value table]
Hence, the probability that a randomly chosen student will take more than 30 minutes to complete the exam = 0.8413
60/100 of a mile because if in three seconds it goes 3/100 it would mean 1/100 would be one second and one minute is 60 seconds so it would be 60/100 of a mile
These lines are perpendicular because y = -6 is a horizontal line with a slope of 0 and x = 6 is a vertical line with an undefined slope
Answer:
a 270° rotation about point P
Step-by-step explanation:
Because after transformation MK and M'K 'are at 90°, that implies that MK is rotated as 90 ° clockwise around P or 270 ° counterclockwise around P.
Therefore the transformation composition that maps
to
K"L"M",
So, for this composition, the first transformation is 270° is the 270° rotation i.e to be counterclockwise about point P.
While the transformation of the second would be down translation that goes to the right.
hence, the last option is correct
