Answer:
The probability that the next color will be red is: 
Step-by-step explanation:
The probability of an event is defined as:
Probability=(Total number of favourable outcomes)/(Total number of outcomes )
Here we have to find the probability that the next colour is red is given by:
<em>The recordings are given as:</em>
B R Y R R R R Y R B R R
Number of outcomes that red will come up=8
Total number of outcomes=12
Hence the probability is given by:
Answer:
3.6 in³
Step-by-step explanation:
If each cube is 1/5 inch:
15 cubes along the length = 15÷5 = 3 inches
5 cubes along the height = 5÷5 = 1 inch
6 cubes along the width = 6÷5 = 1.2 inches (1 and 1/5)
V=lwh=3*1*1.2= 3.6 in³
3/5*3/3=9/15
1/3*5/5=5/15
15 is a common denominator.
9514 1404 393
Answer:
- 3 ounces of 75%
- 7 ounces of 45%
Step-by-step explanation:
Let x represent the number of ounces of 75% silver needed. Then (10-x) is the number of ounces of 45% silver. The total silver required is ...
0.75x +0.45(10 -x) = 0.54(10)
0.30x +4.5 = 5.4
0.30x = 0.9
x = 0.9/0.3 = 3 . . . . . ounces of 75% silver
10-x = 7 . . . . . ounces of 45% silver
Luis needs 7 ounces of 45% silver and 3 ounces of 75% silver.
