Which point represents the outlier? OA. (2,3) O B. (4, 5) O C. (3, 13) OD (8,9)

Mrac [35]

Picture relating to the required graph is attached below

Answer:

C. (3, 13)

Step-by-step explanation:

According to the inspected scatterplot, we could actually observe a possible data trend which is where the majority of the samples are clustered. In a graphical representation of data, data points which deviates away from the trend of the majority of the points are considered as outliers. In the scenario above, the point (3, 13) seems too far off from the actual trend line, thus showing a greater y value than the pattern actually predicts.

I need helpp ..

There are 60 cubic units in the provided three-dimensional figure, and the units are mm³, cm³, and m³.

<h3>What is volume?</h3>

It is defined as a three-dimensional space enclosed by an object or thing.

We have a three-dimensional shape shown in the picture with dimensions.

The total cubic units = 4×3×5 = 60 cubic cm

We can measure the volume with units of mm³, cm³, m³, km³

We can draw a relation between them:

mm³<cm³ <m³< km³

For the first picture, the unit mm³ would be best for measuring the volume.

For the second picture, the unit cm³ would be best for measuring the volume.

For the third picture, the unit m³ would be best for measuring the volume.

Thus, there are 60 cubic units in the provided three-dimensional figure, and the units are mm³, cm³, and m³.

On Friday and Saturday, there were a total of 200 cars in the parking lot of a movie theater. On Friday, 120 cars were in the pa

denpristay [2]

Answer:

(A) 40%

(B) 60%

Step-by-step explanation:

Given:

Total number of cars = 200

Cars in parking lot on Friday = 120

Total number of cars = Total cars on Friday + Total cars on Saturday.

⇒ 200 = 120 + Total cars on Saturday.

⇒ Total cars on Saturday = 200 - 120 = 80

So, 80 cars were in parking lot on Saturday.

(A)

Percentage of cars in parking lot on Friday is given as:

$=\frac{\textrm{Cars in parking lot on Friday}}{\textrm{Total cars parked}}\times 100\\\\=\frac{120}{200}\times 100\\\\=\frac{120}{2}=60\%$

Therefore, 60% of the cars were in the parking lot on Friday.

(B)

Now, since 60% of the cars were parked on Friday, the remaining percent will be on Saturday.

Therefore, percentage of cars in parking lot on Saturday = 100% - 60% = 40%. This can be verified with the same formula used in part (A).

$=\frac{\textrm{Cars in parking lot on Saturday}}{\textrm{Total cars parked}}\times 100\\\\=\frac{80}{200}\times 100\\\\=\frac{80}{2}=40\%$

PLEASE HELP. I need DE AND EF!!!

AlekseyPX

Answer:

DE = about 41.843 (rounded to nearest thousandth)

EF= 34.276 (rounded)

Step-by-step explanation:

For DE, we know that the shorter side (the opposite side) is 24, while the angle across form it is 35°. We can use trigonometry to figure this out. SinФ equals the opposite side (in this case, 24) divided by the hypotenuse. Set sinФ equal to a ratio of the sides like this:

sin(35) = $\frac{24}{x}$

x represents the hypotenuse length, which we don't know; 35 is the angle measure. Next, isolate x so that the equation looks like this:

$\frac{24}{sin(35)}$ = x

You will need a calculator for the next part. (and make sure you're in degree mode!). evaluate sin(35) and divide 24 by that value. That is DE's length. DE = about 41.843 (rounded to nearest thousandth)

For EF, we can just use Pythagorean theorem now that we know the other sides' values.

EF^2 + 24^2 = DE^2

*a calculator might also be useful for this part.

EF= 34.276 (rounded)
