Answer: 0.089
Step-by-step explanation:
Number of combinations of n things taking r at a time :-
Given : A box has eight green marbles, five red marbles, and seven blue marbles.
Total marbles = 5+8+7=20
We choose three marbles from the box at random without looking.
Number of ways to choose 3 marbles with same color :-
(1)
Total ways to select 3 marbles from 20 marbles :-
(2)
Now, the required probability (divide (1) by (2)):-
Hence, the required probability : 0.089
Answer:
A. 105°
Step-by-step explanation:
∠4 + ∠5 = 150
∠4 ≅ ∠5
150 ÷ 2 = 75
∠4 = 75
∠5 = 75
180 - 75 = 105
∠1 = 105
Answer:
1x+ 1y =11
10x + 5y = 80
x = the cost of a taco = $5
y = the cost of a burrito = $6
Step-by-step explanation:
x = the cost of a taco
y = the cost of a burrito
1x+ 1y =11
10x + 5y = 80
rearange 1st equation as y = 11 -x and plug in into the 2nd one for y:
10x + 5( 11-x) = 80 distribute left side
10x + 55 - 5x = 80 combine like terms
10x - 5x = 5x
5x + 55 = 80 subtract 55 from both sides
5x = 80 - 55
5x = 25 divide by 5
x = 5
plug in for y in 1st equation y = 11--x =11-5 = 6
I believe that 30% is greater than 0.4
