Total marbles = 40 & 1/4 (or 0.25) are, then RED = 40x 0.25 = 10
If RED = 10 then BLUE = 30
P(picking one blue) = 30/40 = 3/4 =0.75

Answer:
We conclude that the expression of the price p of a coat reduced by a 5% discount will be: 0.95 p
Step-by-step explanation:
Let 'p' be the original price
Discount = 5% = 0.05
The discount amount can be calculated by multiplying the original price by 5% or 0.05
Discount Amount = 5% × p
= 0.05 × p
= 0.05 p
Given that the price p of a coat reduced by a 5% discount.
Thus, the price after 5% discount can be calculated by subtracting the discount amount i.e. 0.05 p from the original price p.
Thus,
The expression of the price p after 5% discount = p - 0.05 p
= 0.95 p
Therefore, we conclude that the expression of the price p of a coat reduced by a 5% discount will be: 0.95 p
Answer: The correct option is D.
Explanation:
It is given that the triangle ABC is an isosceles triangle. It is also given that the line BD is the median of triangle ABC.
Since DB is median it means point D divides the line AC in two equal parts.
The The median of an isosceles triangle is always a perpendicular bisector of the opposite side. Since the median is perpendicular on side AC, therefore the sides AB and CB are equal.
In triangle ABD and CBD,
.... (Isosceles triangle)
.... (D is midpoint of AC)
.... (Common Side)
Therefore option D is correct.
