I think its b , but iam not sure
Answer:
B) -420
Step-by-step explanation:
Step 1: Plug in 432 as the w variable. Then, the equation becomes 3√4(432) - 432.
Step 2: Multiply 4 and 432 together. The product should be 1,728.
Step 3: Find the cubic root of 1,728. 3√1,728 is 12.
Step 4. Subtract 432 from 12. 12 - 432 is -420.
Answer:
Barett Sold 88 Tickets
Step-by-step explanation:
To Start off we are told that the Total of tickets sold between Amelia (A) and Barrett (B) was 137.
Total = 137
Since Barett Sold 10 less than twice as many tickets as Amelia, we can make the following equation, where Barett is B and Amelia is A.
A + B = 137
A + (2A-10) =137 (Barett equalls 10 less than twice Amelia)
Now we can solve the equation for A
A + (2A-10) =137
3A - 10 = 137 (Combine Like Terms)
3A = 147 (add 10 on both sides)
A = 49 (divide by 3 on both sides)
Now that we have the amount of tickets that Amelia sold we can plug it in for B to find out how many tickets Barett Sold
(2A-10) = B
(2*49) - 10 = B
(2A-10) = B
98 - 10 = B
88 = B
Experimental probability of the name Alex being drawn is 4/10
This is because out of the ten times a name was drawn, Alex was drawn four times.
If the experiment was repeated 1,000 times, Ella's name could be expected to be drawn 200 times.
This is because of the ten names drawn, Ella's name was drawn twice which is 20% and 20% of 1,000 is 200.
Start with the given 4x + 1 = 6x - 2.
Combining like terms, we get 3 = 2x, from which we later get x = 3/2.
Where the question mark appears, write, "Reverse the order of 3/2 = x to obtain x = 3/2."
