Answer:
0.1052 = 10.52%
Step-by-step explanation:
The question missing the number of red marbles, it should be 5.
You select 2 marble randomly without replacement. The word without replacement show that you pick the marble at different times, so the order is important. There are 5 red, 8 green, 4 blue, 3 yellow which means the total marble is 8+4+3= 16 marbles. The chance to pick red marble then a green marble will be:
5/20 * 8/19= 2/19= 0.1052 = 10.52%
Answer:
Length of base DE = 24 units
Step-by-step explanation:
Given:
In given triangle, right angle at D
SO,
Perpendicular of given triangle = 32 unit
Hypotenuse of given triangle = 40 unit
Find:
Length of base DE
Computation:
Using Pythagoras theorem
Base = √Hypotenuse² - Perpendicular²
Length of base DE = √Hypotenuse of given triangle² - Perpendicular of given triangle²
Length of base DE = √40² - 32²
Length of base DE = √1,600 - 1,024
Length of base DE = √576
Length of base DE = 24 units
X = -4/3

Answer:
Step-by-step explanation
Hello!
3x/4 + 6=42
3x/4=42-6 = 36
3x = 36*4
3x = 144
x= 144/3 =48
3/4 of 48 = (48*3) / 4 =36
36+6=42
the original number is 48
