Answer:
x= 3/4 or 0.75
Step-by-step explanation:
multiply by 7
-7x+3= 14x-25
3=21x-25
28=21x
x=3/4
Answer: 0.819
Step-by-step explanation:
Given: X is a normally distributed random variable with mean 95 and standard deviation 3.
Then, the probability that X is between 89 and 98 will be:
Hence, the required probability = 0.819
Answer:
37800
Step-by-step explanation:
Prime factorization of the numbers:
180 = 2 × 2 × 3 × 3 × 5
189 = 3 × 3 × 3 × 7
600 = 2 × 2 × 2 × 3 × 5 × 5
LCM (180, 189, 600)
= 2 × 2 × 2 × 3 × 3 × 3 × 5 × 5 × 7
= 37800
Answer:
Answer= 11
Step-by-step explanation:
|7 – (2)| + |3 (2)|

Answer:
125
Step-by-step explanation:
Find the surface area of the table that Raj wants to cover.
Since the side table is a cube each side is identical.
Step 2:
Raj wants to cover 5 sides of the cube. Therefore the total surface area to be covered is 5 · 30 · 30 = 4,500 square inches.
Step 3:
Find the surface area of each tile.
The surface area of each tile is 6 · 6 = 36 square inches.
Step 4:
Find the number of tiles needed to cover the table.
4,500 square inches
36 square inches per tile
= 125 tiles
Raj will need 125 tiles to cover the table.
