It is given here that there is 1/3 probability of professional baseball player will get a hit. Hence if at least three hits are gained out of 5 attempts, the calculation goes: 5C3* (1/3)^3*(2/3)^2 + 5C4* (1/3)^4*(2/3)^1 +5C5 *<span>(1/3)^5*(2/3)^0 equal to 0.21. </span>
Answer:
x= -6
Step-by-step explanation:
Isolate the variable by subtracting 4 from both sides
5x - 14 = 8x + 4 -4
5x - 18 = 8x -5x
-18 = 3x /3
-6 = x
Answer: get the 2 perfums in the size 50ml
Step-by-step explanation:
80ml is 55 pound
50 ml is 45 pound
2nd is half of 45 pound which is 22.5
the 2 perfum in the size 50 ml with the special price is: 45 + 22.5 = 67.5 now per ml is 0.675 pound per ml i found the price per pound by dividing the ml by the price
for the 80ml the price per ml is 0.6875
2(3.14)(14)=87.92
answer is 88
To solve this problem, we can write an equation letting the variable x represent the number of bottles in a box of water (this means that the expression x-1 represents the boxes that have one fewer bottle than a full box).
This allows us to create the following equation:
9 original bottles + 3x (3 full boxes) + 2(x-1) (two boxes with one fewer bottle) = 67 total bottles
OR
9 + 3x + 2(x-1) = 67
Now, we can begin to solve this equation by using the distributive property to get rid of the parentheses on the left side of the equation.
9 + 3x + 2x - 2 = 67
Next, we can combine like terms on the left side of the equation (meaning add the variable terms together and subtract the constant terms).
7 + 5x = 67
Now, we should subtract 7 from both sides of the equation to get the variable term alone on the left side of the equation.
5x = 60
Next, we should divide both sides by 5 to isolate the variable x on the left side of the equation.
x = 12
Therefore, your answer is that there are 12 bottles in a full box.
Hope this helps!
