Answer:
can't help sorry try chrome plz I hope it help you good
Step-by-step explanation:
1. 1/4(x + 12)=2 - first isolate X'
- 12 -12
2. 1/4(x) = -10 - 1/4 since its a fraction, you'll have to subtract not divide
-1/4 - 1/4
3. x = -10.25
Andre did the first step correctly, but on the second step he just divided 1.4 by -10, instead of subtract 1/4 from both sides.
Answer:
B. 733 customers
Step-by-step explanation:
15+30+45=90
since 30 people select a black frame, 1/3 of the customers picked black frames. If this data is consistent through the month (which we have to assume it is) then that means 1/3 of customers select a black frame on average. 1/3 of 2,200 is about 733, so we can assume, using the data given, that about 733 customers selected black frames! :)
Answer:
Step-by-step explanation:
We know that when two events A and B are independent , then the probability of getting A and B will be :-
In a fair dice,total outcomes =6
Number of 2's =1
Then, the probability of getting a 2 =
If you roll one die two times, then the probability of getting a 2 on the first roll and a 2 on the second roll will be:-
Hence, the probability of getting a 2 on the first roll and a 2 on the second roll=
Just write a equation then plus 10 on each side, then it will be 2x=16 and then find x, so it will be 8 because 2 times 8 equal 16
