Hatshy [7]

Answer:

t=\frac{x}{v} = \frac{234 miles}{70 miles/h} = 3.34 h

t= 03:21 h

Step-by-step explanation:

A constant speed means that it does not change over a period of time and direction of motion. A simple formula, for this case (constant speed)

v =\frac{x -xo}{t-to} where x is distance and t time. The subtract is final value minus initial value

If xo=0 miles and to=0 h, then

v=\frac{x}{t}

We have distance, and speed so we need to calculate the time (how long)

t=\frac{x}{v} = \frac{234 miles}{70 miles/h} = 3.34 h

t= 03:21 h

The distribution of exam scores (ranging from 0 - 100%) where the mean score is 75%, the standard deviation is 12%, and the medi
AnnyKZ [126]

Answer:

Right skewed

Step-by-step explanation:

A skewed right distribution by definition is "one in which the tail is on the right side".Or on simple words when we have the following property:

Mode

Or equivalently:

Mean> Median>Mode

A skewed left distribution by definition is "one in which the tail is on the left side". Or on simple words when we have the following property:

Mode>Median>Mean

Or equivalently:

Mean< Median

And for this case we can see that Mean =75> Median =78

So on this case the best description for this distribution is right skewed.
