A mean is an arithmetic average of a set of observations. The average time taken by Shiho to complete the track is 3.7 seconds.

<h3>What is Mean?</h3>

A mean is an arithmetic average of a set of observations. it is given by the formula,

\rm Mean=\dfrac{\text{Sum of all obervation}}{\text{Number of observation}}

The reading of the 5 trials of Shiho is 3.3 seconds, 3.8 seconds, 4.1 seconds, 4.1 seconds, and 3.1 seconds. Therefore, the average or the meantime of Shiho can be written as,

\rm \text{Average Time} = \dfrac{\text{Sum of all observations}}{\text{Number of trials}}\\\\\text{Avrage Time} = \dfrac{3.3+3.8+4.1+4.1+3.1}{5}=\dfrac{18.4}{5}= 3.68\approx 3.7\ seconds

Hence, the average time taken by Shiho to complete the track is 3.7 seconds.

In the standard (x, y) coordinate plane, if the x-coordinate of each point is 2 times the y-coordinate, what is the slope of the
aleksklad [387]

Answer:

the slope is 1/2

Work:

if the x-coordinate is two times the y-coordinate, that means you are going up one over two each time

slope= y2-y1/x2-x1

so you can pick two points, like (2, 1) and (4,2) and use the formula

slope= 2-1/4-2= 1/2

Pls helpPLSSSSSSSSSS
velikii [3]

Answer: $60.00


Step-by-step explanation: First the solution: (Start form the end!!) $40.00 (the ending total) minus the $10.00 he added on, $40-$10=$30 which is half of the original total so now you have to multiply by two to get the starting balance ($60.00)!

Now for the inequality, since we don't know the beginning balance of the gift card that will be our variable.

g

Then, since he spent half of this buying coffee we would have to split our variable in half.

g/2

After that, Peter added an additional $10.00 to said  gift card.

g/2 + 10 = 40

Going off of that the final inequality would be $60.00 = g/2 + 10 = 40


BAMM!! GOOD LUCK IN MATH CLASS!!!
