Answer:
1/4
Step-by-step explanation:
8 blue chips 9 pink chips 1 white chip = 18 chips
P( pink) = pink/total = 9/18 = 1/2
Replace
8 blue chips 9 pink chips 1 white chip = 18 chips
P( pink) = pink/total = 9/18 = 1/2
P(pink, replace, pink) = 1/2 * 1/2 = 1/4
Answer:
+4

The values of x and y are ⇒ x = 4 and y = 9
Step-by-step explanation:
In a parallelogram
1. Each two opposite sides are equal and parallel
2. Each two opposite angles are equal
3. Its two diagonals bisect each other
In parallelogram ABCD
∵ Its diagonal AC and BD intersect each other at point E
∵ AC and DE bisect each other at E
∴ E is the mid-point of AC
∴ AE = EC
∴ E is the mid-point of BD
∴ DE = EB
∵ AE = x + 5
∵ EC = y
∵ AE = EC
∴ x + 5 = y ⇒ (1)
∵ DE = 2x + 3
∵ EB = y + 2
∵ DE = EB
∴ 2x + 3 = y + 2
- Subtract 2 from both sides
∴ 2x + 1 = y ⇒ (2)
Substitute y in equation (2) by equation (1)
∵ 2x + 1 = x + 5
- Subtract x from both sides
∴ x + 1 = 5
- Subtract 1 from both sides
∴ x = 4
Substitute the value of x in equation (1) to find y
∵ x + 5 = y
∵ x = 4
∴ 4 + 5 = y
∴ y = 9
The values of x and y are ⇒ x = 4 and y = 9

Answer:
the number of pints of blue paint did she use for painting her bedroom walls is 1.875 pints
Step-by-step explanation:
The computation of the number of pints of blue paint did she use for painting her bedroom walls is shown below:
= Total pint × blue paint
= 7.5 × (1 - 3 ÷ 4)
= 7.5 × 1 ÷ 4
= 1.875 pints
Hence, the number of pints of blue paint did she use for painting her bedroom walls is 1.875 pints
