Change one to 5/5 because that is equal to one and then subtract the top numbers to get 4/5. Hope this helped.

You have to get both parts (the number and fraction) in the form of a fraction with the same denominator. Since anything divided by itself is equal to one (3/3, 5/5, 19/19, etc) we can write the number 1 as the denominator of the fraction divided by itself. Here's what I mean:
1 - 1/5 = 5/5 - 1/5 = (5-1)/5 = 4/5

And then for the next one:
1 - 3/5 = 5/5 - 3/5 = =(5-3)/5 = 2/5

On a December day, the probability of snow is 0.30. The probability of a "cold" day is 0.50. The probability of snow and "cold"

Margarita [4]

Answer:

Yes, snow and cold weather are independent.

Step-by-step explanation:

We are given the following in the question:

C: Cold weather

S: Snow

P(C) = 0.50

P(S) =0.30

$P(S\cap C) = 0.15$

We have to check whether snow and cold whether are independent events.

If the events A and B are independent then,

$p(A\cap B) = P(A)\times P(B)$

Checking,

$p(S\cap C) = P(S)\times P(C)\\0.15 = 0.30\times 0.50$

Thus, the two events are independent.

For mutually exclusive events

$P(A\cap B) = 0$

Thus, the given events are not mutually exclusive.

Unknown g (x) = ax + b and g (g (x)) = 16x - 15. Calculate the value of a and b.

goblinko [34]

G(g(x))=16x-15
means that when you subsituted g(x) for x in g(x), you got 16x-15

a(ax+b)+b=16x-15
distribute
xa^2+ab+b=16x-15d
we look at the x terms
therefor
xa^2=16x
a^2=16
a=-4 or 4
we will find out

look a constant terms
ab+b=-15
undistribute b
b(a+1)=-15

if a is -4 then
b(-4+1)=-15
b(-3)=-15
b=5

if a=4 then
b(4+1)=-15
b(5)=-15
b=-3

so
g(x)=-4x+5 or
g(x)=4x-3

if a=-4, b=5
if a=4, b=-3
