Answer:
Can you show a picture? Or like tell us the options?
36/40 would be close to 1
Answer:
Step-by-step explanation:
Let t represent the number of teachers.
We have been given that Noor gave 1/3 of a sheet to each of the 45 students at recess.
Let us find the number of sheets given to students by Noor by multiplying the total number of students by the part of sheet given to each student.
So, Noor gave 15 sheets to 45 students.
We have been given that Noor wants to give 
sheet to each teachers, so the number of sheets given to t teachers will be 
.
As Noor has bought 21 sheets, so the number of sheets given to students and t teachers will be less than or equal to 21.
We can represent this information in an inequality as:
Therefore, the inequality represents the number of teachers ,t, Noor could give sheets of stickers too.
To evaluate the given probability we proceed as follows:
The z-score is given by:
z=(x-μ)/σ
where:
μ-mean
σ-standard deviation
from the question:
mean=272, sig=15
but the sample is n=36, thus we shall have:
√σ/n
=15/√36
=2.5
thus the z-score will be as follows:
x=272
z=(272-272)/2.5=0
x=274
z=(274-272)/2.5==0.8
thus
P(272<x<274)
=P(z<0.8)-P(z<0)
=0.7881-0.5
=0.2881
Hence the answer is 0.2881
Answer:
AC = 3x + 3 (answers may vary)
Step-by-step explanation:
AB = 6x + 2
Answers may vary for this question,
Let's say that,
B = 4x + 1
So that means that,
A = 2x + 1
BC = 5x + 3
Since we chose
B = 4x + 1,
we must subtract B from BC to get C,
C = x + 2
Now we add A and C to get AC,
A = 2x + 1
C = x + 2
AC = 3x + 3
