In an anonymous survey 34 students reported the hours they studied for a statistics final exam. The histogram below shows the re

sults of the survey. histogram Which statement below is the most accurate description of the center of the distribution?
A. The median should be used to describe the center, because the values on the horizontal axis can be spit exactly in the middle.
B. The mean should be used to describe the center because it may produce a decimal value, which is more accurate than the median.
C. The mean should be used to describe the center because the data is roughly symmetric.
D. The median should be used to describe the center because, since the data is skewed, the middle outcome may more accurately describe a typical value in the distribution.

Solve for ddd: d+\left(-5.004\right)=2.826d+(−5.004)=2.826d, plus, left parenthesis, minus, 5, point, 004, right parenthesis, eq
sergij07 [2.7K]

Answer:

The value of 'd' is 7.83.

Step-by-step explanation:

Given:

d+(-5.004)=2.826

We need to solve for 'd' .

Solution:

d+(-5.004)=2.826

Now we know that;

By the rule  of Addition and subtraction for positive and negative numbers

when a positive and negative signs are met then the result is negative.

So we can say that;

d-5.004=2.826

Now Adding both side by 5.004 using addition property of equality we get;

d-5.004+5.004=2.826+5.004\\\\d= 7.83

Hence The value of 'd' is 7.83.

A cyclist is travelling at an average speed of 15km/HR. How long will it take to travel a distance of 52 1/2km
vitfil [10]

Answer:

3.5hour

Step-by-step explanation:

Average speed = Distance/Time

Given

Distance = 52 1/2 km

Speed = 15km/hr

Required

Time

Substitute the given values in the formula

Time = (52 1/2)/15

Time= 105/2 * 1/15

Time = 105/30

Time  = 3.5hour

hence it will take 3.5hr to travel a distance of 52 1/2km

A shipping company uses an inclined conveyor belt to load or unload packages. The dock is 15 feet above ground. The base of the
alexgriva [62]
Hey there! :D

Think of this like a triangle. The dock is 15 feet above ground. It is the side of the triangle. The line connecting the bottom of the dock to the base of the conveyor belt is 40 feet. This is like the base. 

The conveyor belt itself is at a diagonal, and should be the hypotenuse. 

Use the Pythagorean theorem. 

a^2+b^2=c^2

15^2+40^2= c^2 

225+1,600= c^2

Add the values together. 

1,825= c^2

Find the square root of 1,825. 

c= 42.7 (rounded to the nearest tenth) 

The conveyor belt is 42.7 feet long.

I hope this helps!
