2 weeks = 14 day

A taxi service offers a ride with an $5 surcharge and charges $0.50 per mile. How many miles can a customer travel and spend at
hram777 [196]

Charges 0.50 per mile with a 5 dollar surcharge. Spending at most 30 dollars, the equation would be:

0.5x+5\leq30

To find how many miles they can travel/the solution, solve the inequality:

0.5x+5\leq30

Subtract 5 from both sides.

0.5x\leq25

Divide both sides by 0.5.

x\leq50

They can travel (at most) 50 miles.

Hope this helps :)

The following describes a sample. The information given includes the five number summary, the sample size, and the largest and s
lys-0071 [83]

Answer:

L= Q_1 - 1.5*IQR = 210 -1.5*40 =150

U= Q_3 + 1.5*IQR = 250 +1.5*40 =310

And if we analyze the info provided we have 500 values

Tails: 160,165,167,171,175,...,268,269,269,269,270,270

So as we can see on the tails any values is <150 or >310 so then for this case we cannot consider as outliers any of the values on the tails of the distribution.

Step-by-step explanation:

For this case we have the 5 number summary

(160,210,220,250,270)

So then we have:

minimum = 160 , Q1 = 210, Q2= Median=220, Q3 = 250, Max=270

If we find the interquartile range we got:

IQR = Q_3 -Q_1 = 250-210 =40

For this case we need to find the lower and upper limit with the following formulas:

L= Q_1 - 1.5*IQR = 210 -1.5*40 =150

U= Q_3 + 1.5*IQR = 250 +1.5*40 =310

And if we analyze the info provided we have 500 values

Tails: 160,165,167,171,175,...,268,269,269,269,270,270

So as we can see on the tails any values is <150 or >310 so then for this case we cannot consider as outliers any of the values on the tails of the distribution.

Gold in the form of solid cylinders will be molded into solid blocks. Each cylinder has a diameter of 6.18 cm and a height of 6
MrMuchimi
The formula for the volume of a cylinder is
V = pi*h*(d/2)^2
The volume of one cylinder has V = 3.14159*6*(6.18/2)^2 =179.98 cm3
To get the number of cylinder, 360/179.98 = 2 cylinders

I need help finding domain and range
kow [346]

9514 1404 393

Answer:

  • domain: [2, 6]
  • range: [6, 18]

Step-by-step explanation:

The domain is the horizontal extent of the graph. When end points are involved, you have to be able to tell if they are included in the function definition, or not. Here, the solid dots mean both end points are included.

The graph extends horizontally from 2 to 6. You read this from the "x" scale at the bottom. As an inequality, the domain is written ...

  2 ≤ x ≤ 6

In interval notation, it is [2, 6]. Square brackets are used to indicate the end point values are included.

__

The range is the vertical extent of the graph. This one extends from y=6 to y=18. You read this from the "f(x)" scale on the left. The range can be written as ...

  6 ≤ y ≤ 18

  [6, 18]
