Answer:
It is unlikely to have thunderstorms tomorrow
Step-by-step explanation:
20% chance mean 20/100 = 0.2
The probability of having the even is 0.2
Remember of the probability of having an even is 0 -0.5 then the event is unlikely to happen
if the probability is 0.5 we have a 50% chance of the even happening
If the probability is 0.5 to 1 then the event is likely to happen
If the probability is 1, that event will happen
A point, and nothing more
Answer:
there are 12 red marbles
Step-by-step explanation:
Answer:
(- 3, 0 ) and (1, 0 )
Step-by-step explanation:
Given
y =2x² + 4x - 6
To find the x- intercepts let y = 0, that is
2x² + 4x - 6 = 0 ← divide all terms by 2
x² + 2x - 3 = 0 ← in standard form
(x + 3)(x - 1) = 0 ← in factored form
Equate each factor to zero and solve for x
x + 3 = 0 ⇒ x = - 3
x - 1 = 0 ⇒ x = 1
The x- intercepts are (- 3, 0 ) and (1, 0 )
Given the proportion 7/5=x/3, you can cross-multiply to find the value of x.
21=5x.
Divide both sides by 5.
x=4.2.
Hope this helps!
