Obtaining a measure of intelligence from a group of college students would likely yield a somewhat normal distribution (that is,
ki77a [65]

Answer:

C. Mean

Step-by-step explanation:

We have been given that obtaining a measure of intelligence from a group of college students would likely yield a somewhat normal distribution (that is, there shouldn't be any extreme outliers).

We know that median is best measure of central tendency with extreme outliers, while mean is the best measure of central tendency when the data is normally distributed.

Mode is used when data are measured in a nominal scale.

Since the measure of intelligence from a group of college students yield a somewhat normal distribution, therefore, mean will be the best measure of central tendency.

Suppose that a large pumpkin empty a swimming pool in 40 hours and that a small pumpkin empty a pool and 70 hours working togeth
Norma-Jean [14]

Answer:

Total 25.45 hours will be taken to empty the pool.

Step-by-step explanation:

Time taken by large pumpkin to empty the pool=40 hours

Time taken by the smaller pumpkins to empty the pool=70 hours

Amount of pool emptied by large pumpkin in one hour=\frac{1}{40}

Amount of pool emptied by small pumpkin in one hour=\frac{1}{70}

Amount of pool emptied in one hour if both pumpkins work together=

\frac{1}{40}+ \frac{1}{70}

=\frac{11}{280}

Therefore, the no. of days will be the reciprocal of the amount of work done in one hour ie . \frac{280}{11}

Total 25.45 hours will be taken to empty the pool.

Determine whether y varies directly with x. If so, find the constant of variation k.
kumpel [21]
Direct variation is y=kx, inverse variation is y=k/x....

-5y=-2x divide both sides by -5

y=2.5x

So this is a direct variation with a constant of 2.5
