A box contains balls numbered 1 through 5. You are to draw a ball from the box and you will be paid 12 chips if the number is even. However, you are going to pay 7 chips if the number is odd. What is the standard deviation of the possible results?

false

step-by-step explanation:

false.   two legs of the trapezoid would be congruent, but the other two would not.   were all the legs congruent, then we'd have a square; were the 2 shorter sides congruent and the 2 longer sides also congruent, we'd have a rectangle.

answer: first option i.e. 'a' is correct.

step-by-step explanation:

since we have given that

number of minutes to wrap a small gift box = 4 minutes

we need to find the number of gifts to be wrapped in 5 minutes

since there is a direct variation, as the number of minutes will increase with   number of gifts to be wrapped.

so, let the number of gifts to be wrapped in 5 minutes be x.

so, it becomes,

hence, first option 'a'   is correct.

i'm assuming that it's c.)   volcanoes built the mountains and earthquakes tore them down.

and?
