Answer: Option 'C' is correct.

Step-by-step explanation:

Since we have given that

Mean score = 96

Sample size = 100

We need to find the distribution of the test scores is likely to be :

In negatively skewed, the mean is to the right side.

It also shows that the tail on the left side is longer than the tail on the right side.

And the bulk value lies in the right of the mean.

In our situation, mean is to the right side and tail is to the left side.

Hence, it is negatively skewed.

Therefore, Option 'C' is correct.

Crank

Answer:

Step-by-step explanation:

Yes, it's reasonable.

What you are doing is solving the question by rounding. You come up with an answer. Suppose you loose the decimal somewhere and you get 0.36? Is that reasonable? Do you just write the answer in the provided blank and move on. What now?

You get it wrong?!!

But your estimate should be about 9/3 = 3. Now you look at your calculator with great misgivings, because it made a mistake. Did it or did you? Well ultimately you did, but you have to blame something. So the calculator takes the heat.

Who  knows? Maybe the decimal doesn't work. It's stuck or something. In any event you should be aware that there's no way the answer could be 0.36 when you estimate it to be 3.

Gwar [14]

Answer:

a) t₀ =  1.73205 s

b) 1.0 C

Step-by-step explanation:

(A)

The time dilation (t) observed by an observer at rest relative to the time (t₀) measured by observer in motion is;

t = \frac{t_0}{\sqrt{1 - \frac{V^2}{C^2}}}

t_0 = t \sqrt{1 - \frac{V^2}{C^2}} time measured by captain

⇒ t_0 = 2.0 \sqrt{1 - \frac{0.5^2C^2}{C^2}}             V = 0.5 c

⇒ t₀ =  1.73205 s

(B)

Speed of the light never exceeds by its real value. The speed of the light in any frame of reference is constant.

∵ It will be "1.0C" or just "C"

Find the slope of the line passing through the points (-5,3) and (-7,5).
Alekssandra [29.7K]

Step-by-step explanation:

points (-7,5) and (5,-3)?

This would mean to subtract the y coordinates:

5 - (-3) = 8

Then subtract the x coordinates in the same order:

-7 - 5 = -12

Then divide the y result by the x result for the slope:

8/-12 is the slope.

In simplest form, this is equivalent to -2/3
