Answer:
independent, 1/4
Step-by-step explanation:
The events are independent because what occurs on the first flip does not affect the second flip
P(heads) = 1/2
P(heads, heads) = 1/2*1/2 = 1/4
If 4/5 is 2 pounds, wouldn't that mean 2.5 pounds at full?
Answer:
75 total tickets
Step-by-step explanation:
METHOD 1:
We know that 45 children's tickets have been sold, being 60% of the total tickets having been sold.
So, basically, we solve for x:
We have, 60% × x = 45
or, 60/100 × x = 45
Multiplying both sides by 100 and dividing both sides by 60,
we have x = 45 × 100/60
x = 75
If using calculator, enter 45x100/60, which will give you the answer.
------------------------
METHOD 2:
Division is the opposite of multiplication
Start with the formula to calculate the percentage of total
y=value÷ percentage/100
Substitute values in the equation
y=45÷60/100
Simplify and solve
y=45÷0.6
y=75
Both methods give you 75, therefore 75 tickets have been sold
The second 'p' is supposed to be 'e'. With that correction,
those letters can be unscrambled to spell " expand ".
Now it's your turn. Unscramble " Algerba ".
Answer:
1.5q - 5r = 2
Step-by-step explanation:
All you need to do here is negate each term inside the brackets, which allows you to get rid of the minus sign and the brackets.
-(-1.5q + 5r) = 2
is exactly the same as saying:
-1 × (-1.5q + 5r) = 2
And if we multiply each term in the brackets by negative one, we get:
(1.5q - 5r) = 2
And now the brackets can go, leaving you with:
1.5q - 5r = 2
