We can use proportion to solve it
135 berries -------------15min
486 berrier --------------x
Our x is equal to =x= \frac{486*15}{135} =54min
Its our result

Tamiku [17]

Answer: The lenght of the missing side is 4 cm

Step-by-step explanation:

The correct question is:

<em>The perimeter of the rectangle is 20cm . One side is 6cm. What is the length of the missing side?</em>

So, to answer it we have to apply the next formula:

Perimeter of a rectangle = 2 width + 2 length

Replacing with the values given: (assuming that the side given is the length of the rectangle)

20 = 2(6) + 2x

Solving for x:

20 =12 +2x

20-12 =2x

8 =2x

8/2 =x

4=x

The length of the missing side is 4 cm

For the events "shower gel” and "scented” to be independent, what must be shown to be true? P(lotion) = 42% P(scented) = 42% P(s
madreJ [45]
Hi, I was able to find the full context for this one from another source:

<span>"Juanita has a storage closet at her shop with extra bottles of lotion and shower gel. Some are scented and some are unscented. If she reaches into the closet and grabs a bottle without looking, she has a 42% chance of grabbing a bottle of shower gel."

For the "shower gel" and "scented" to be independent given the situation above, we need to show that P(A | B) = P(A). You can get this equation from the definition of "independence" where P(A </span>∩ B) = P(A)*P(B) and the formula for conditional probability P(A | B).

We only have the given P(shower gel) = 42% therefore the event "shower gel" must be the variable A.

ANSWER: To show independence of the two events, P(shower gel | scented) = 42% must be true.
