Find the mode of the following number of countries randomly selected travelers visited in the past two years. 13,13,15,7,8,4,4,7

Aliun [14]

Answer:

The mode of the following number of countries randomly selected travelers visited in the past two years is 13.

Step-by-step explanation:

The mode of a data-set is the value that appears the most commonly, the most frequently.

In this data-set:

13 appears 3 times

7 and 4 twice

The others once

So 13 is the mode.

You run at a pace of 8.5 minutes per mile in a 26.2 mile marathon. How many minutes will it take finish?

algol [13]

8.5 minutes per mile is equivalent to

17 minutes
----------------
2 miles

and the reciprocal of that is

2 miles
-----------
17 min

Now multiply 26.2 miles by

17 min (17 min)* (26.2 mi)
------------ , obtaining ---------------------------
2 miles 2 mi

This simplifies to (17)(26.2)/2 minutes = 222.7 minutes,

or

222.7 minutes 1 hr
-------------------- * ------------ = 3.7 hours
1 60 min

Which statement(s) could describe the graph of a nonproportional relationship? Select all that apply

Solnce55 [7]

Answer:

A. The positive y-intercept.

D. The y-intercept is negative.

Step-by-step explanation:

The proportional relationship is defined by the graph passing through the origin i.e. the y-intercept is equal to zero.

The equation of y proportional to x relationship is y = kx, which again denotes that the graph passes through the origin (0,0).

Now, the statements that can describe the graph of a non-proportional relationship are

A. The positive y-intercept.

D. The y-intercept is negative. (Answer)

1. Determine a rule that could be used to explain how the volume of a

Eva8 [605]

Answer:

See explanation

Step-by-step explanation:

Solution:-

- We will use the basic formulas for calculating the volumes of two solid bodies.

- The volume of a cylinder ( V_l ) is represented by:

$V_c = \pi *r^2*h$

- Similarly, the volume of cone ( V_c ) is represented by:

$V_c = \frac{1}{3}*\pi *r^2 * h$

Where,

r : The radius of cylinder / radius of circular base of the cone

h : The height of the cylinder / cone

- We will investigate the correlation between the volume of each of the two bodies wit the radius ( r ). We will assume that the height of cylinder/cone as a constant.

- We will represent a proportionality of Volume ( V ) with respect to ( r ):

$V = C*r^2$

Where,

C: The constant of proportionality

- Hence the proportional relation is expressed as:

V∝ r^2

- The volume ( V ) is proportional to the square of the radius. Now we will see the effect of multiplying the radius ( r ) with a positive number ( a ) on the volume of either of the two bodies:

$V = C*(a*r)^2\\\\V = C*a^2*r^2$

- Hence, we see a general rule frm above relation that multiplying the result by square of the multiple ( a^2 ) will give us the equivalent result as multiplying a multiple ( a ) with radius ( r ).

- Hence, the relations for each of the two bodies becomes:

$V = (\frac{1}{3} \pi *r^2*h)*a^2$

&

$V = ( \pi *r^2*h)*a^2$
