The outcomes on rolling a 5-sided die are : {1,2,3,4,5,6}
The factors of these outcomes are:
1 = 1 x 1
2 = 1 x 2
3 = 1 x 3
4 = 2 x 2
5 = 1 x 5
6 = 2 x 3
1 is not a prime number. So the numbers which have 2 prime factors are 4 and 6.
Thus, number of favorable outcomes = 2
The probability of rolling a number with exactly 2 prime factors = 2/6 = 1/3
Answer:
20 blue fish
Step-by-step explanation:
Number of blue fish = x
Number of red fish = x+10
Red fish = 60% of total = 0.6
Total fish = x+x+10 = 2x+10
0.6 = (x+10)/(2x+10)
Solve for x:
1.2x+6 = x+10
0.2x = 4
x = 20
Hope this helps!

Answer:
4050 sq. feet.
Step-by-step explanation:
Fencing is done on three sides of the rectangular area.
Given that there are 180 feet of fence available.
Then 2L + W = 180 ........(1), where L = length and W = width, of the rectangular plot.
Now, the area of the plot is given by A = LW
Now, from equation (1), we ger A = L (180 - 2L) ..... (2)
Then differentiating with respect to L in the both sides we get,
{Since condition for Area to be maximum is
}
⇒ L = 45 feet.
Now, from equation (2), we have
square feet.
2.8 millimeter to meters is .0028 but to tell you, you didn't word the question correctly at there no such thing as expanded form
Answer:
1 and 3/8 of pizza
Step-by-step explanation:
5/8 + 3/4
3/4 x 2 to get the same denominator as 5/8
5/8 + 6/8 = 11/8
11/8 = 1 3/8
