The answer to this is -5 because 2 negatives = a positive
Answer:
12 percent
Step-by-step explanation:
2.5 ÷ 100 = 0.025
2.8 - 2.5 = 0.3
0.3 ÷ 0.025 = 12
You would cross multiply the numbers to get 8x=15.
Then you would take away the 8 from both sides so you would divide it.
You are now left with x=1 7/8
Therefore that is your answer.
Answer:The right answer will be
0. 546875
Step-by-step explanation:
When 6 coins are tossed , the total number of outcomes is 2*2*2*2*2*2= 64
The number of ways of getting two heads are 6!/2!*4!=15.
The probability of getting two heads P(A) is 15/64 .
In the same way, the probability of getting three heads P( B) is 5/16.
Now, P(A)+P(B)= 0.546875
Answer:
0 < y ≤ 72.
Step-by-step explanation:
We are given the maximum length of the tray is 12 inches. This implies that;
x + 5 ≤ 12
x ≤ 7
Therefore, the maximum value of x is 7 inches. The maximum width will thus be;
x - 1 = 7 - 1 = 6 inches.
The maximum area, y, will thus be;
Area = length * width
Area = 12 * 6 = 72
The reasonable domain will thus be;
0 < y ≤ 72.
The area is simply between 0 and 72. The area of any object can not be negative.
