Answer:

265.65

Step-by-step explanation:

6.25*8 =50

6.25/2=3.13

50+3.13=53.13

53.13*5=265.65

Answer:

$265.63 or ($265.625)

Step-by-step explanation:

So we wanna find out the total money bob would make :P

First we wanna see how much bob makes in a day

Bob works 8.5 hours a day and get 6.25 every hour:

With this info we can make the expression: 8.5 * 6.25 which equals 53.125

Then we wanna find out how much he makes in a 5 day week so:

We can make the equation 53.125 * 5 which equals 265.625

We can round 265.625 to <em>265.63</em>

You would cross multiply and get 140=10h and you divide both sides by 10 and get 14=h. So the flagpole is 14 feet tall.

In your own words, describe to someone who knows only a little statistics how to recognize when an observation is an outlier. Wh

erik [133]

Answer:

Step-by-step explanation:

In statistics, an outlier is a data point that differs significantly from other observations.

This can happen because of different reasons: it may be due to variability in the measurement or it may indicate an actual experimental error. If it is an actual experimental error then it can create problems when doing the statistical analysis.

A) We can say that this is true, the outliers are observed values far from the other data, however we can make a much deeper analysis of this.

B) This is the right answer, since we don't know what is really causing the outlier, we need to take a closer look to see if they are just mistakes (and therefore be removed). If they are not mistakes we need to do the analysis with and without them to reach correct conclusions.

C) this is wrong because although the part of the histogram is true. It is not true that they should be ignored.

d) The outliers differ significantly from the other data but this doesn't make them the minimum and maximum values in a data set and therefore they should not be treated as such.

Therefore, the correct answer is B)

What is the slope-intercept form of the function that contains the point (8, 12) and has a slope of _2?

Crank

The function has a slope : m = - 2 and contains the point ( 8, 12 ).
y = m x + b
12 = ( - 2 ) * 8 + b
12 = - 16 + b
b = 12 + 16
b = 28
The slope-intercept form of the function is:
y = - 2 x + 28

A shop in the mall is 8 yards by 12 yards. How much would it cost to recarpet the shop with carpet that costs $2.69 per square y

valentinak56 [21]

Answer:

Step-by-step explanation:

You will first have to find the area to find the price of each square yard.

Area is 8*12 = 96. Multiply this by 2.69.

It will cost 258.24 dollars to recarpet the shop.

Let me know if this helped

A discuss moves from P1 (4,8) to P2 (15,17). What is the lincar displacement in the horizontal and vertical directions? What is

Yakvenalex [24]

Answer:

The horizontal displacement is 11 units, the vertical displacement is 9 units, and the projection angle is 39.3 degrees.

Step-by-step explanation:

We can start using the definition of displacement in one dimension between any 2 points which is the difference between them, so we have

$\Delta s = s_2-s_1$

And apply it to get the horizontal and vertical displacements.

Once we have found them, we can use trigonometric functions to find the projection angle with respect the horizontal.

Linear displacements.

Using the definition of displacement, we can write the horizontal displacement as

$\Delta x = x_2-x_1$

So we can use the given points $P1:(x_1,y_2) \text{ and } P_2: (x_2,y_2)$ on the displacement formula

$\Delta x = 15-4\\\Delta x = 11$

In the same manner we can look at the y components of those points to find the vertical displacement

$\Delta y = 17-8\\\Delta y =9$

Thus the horizontal displacement is 11 units and the vertical displacement is 9 units.

Projection angle.

The projection angle with respect the horizontal is the angle that is made between the line that connects the points P1 and P2 and the horizontal, so we can use the linear displacements previously found to write

$\tan(\theta) = \cfrac{\Delta y}{\Delta x}$

Solving for the angle we get

$\theta = \tan^{-1}\left(\cfrac{\Delta y}{\Delta x}\right)$

Replacing values

$\theta = \tan^{-1}\left(\cfrac{9}{11}\right)$

Which give us

$\theta = 39.3^\circ$

So the projection angle is 39.3 degrees.
