Answer: its probably 5
Step-by-step explanation:
simplify the fraction=
(
). Then cancel the common factor of 4=
, then evaluate the exponent = 5
Add up the number of students within the random sample data:
32+26+28+22 = 108
We can then use proportional fractions / cross-multiply to answer the question.
In a sample size of 108 students, 32 of them preferred Movie A.
There are 900 students in total.
32*900 = 28800
108*x = 108x
108x = 28800
x =
or 
In decimal form that is approximately 266.667 and round that to the nearest whole number, you get 267 students who would prefer Movie A.
Answer:
12
Step-by-step explanation:
13.5 + 0.5n =19.5
0.5n=19.5 - 13.5
0.5n=6
n=6/0.5
n=12
Step-by-step explanation:
We know that
Volume of square pyramid = a² × h/3
=> (12)² × 8/3
=> 144 × 8/3
=> 48 × 8
=> 384 in³
Now,
We need to find ratio for finding the times of the volume
=> 3456/384
=> 9
Hence,
Volume of pyramid B is 9 times greater than the volume of pyramid A
For this question first you should find the area of the triangle so you should say:
3*6/2 = 18/2 = 9 ft
now you should find the area of the rectangular so you should say:
16*8 = 128 ft
now you should add them together so you will have:
128 + 9 = 137 square foot :)))
i hope this is helpful
have a nice day
