Answer:
P(n) = 0.5
Step-by-step explanation:
For two events which are independent, we use the multiplication rule which states P (A and B) = P(A) * P(B). Substitute P(m) = 0.4 and P(m and n) = 0.2 into this formula.
P (m and n) = P(m) * P(n)
0.2 = 0.4*P(n)
Divide by 0.4 on both sides.
0.2 / 0.4 = P(n)
0.5 = P(n)
700.000 = 7 . 10 . 10 . 10 . 10 . 10
We know that equal bases sum the exponents, so,
7 . 10^(1 + 1 + 1 + 1 + 1)
7 . 10^5 = 700.000
But we can also say:
(7 . 10) . 10^4
or
(70 . 10) . 10³
or
(700 . 10) . 10²
or
(7000 . 10) . 10
As we can see, the alternative C shows (7 . 10) . 10^4 which can be a correct ans, so, alternative C.
Answer:
25.13cm
Step-by-step explanation:
formula for circumference of a circle is (2r)π with r being the radius
since the problem gave us the diameter already we can change the formula to 8π (2r is equal to the diameter since diameter is twice as long as the radius)
this gives us the circumference of 25.13

Solution:
72 tropical fish and 5/9 sold.
72 / 9 = 8
8 * 5 = 40
72 - 40 = 32
