Answer:

0.8315 = 83.15% probability that a randomly selected gas station in France charges more than $5.30 per gallon

Step-by-step explanation:

Normal Probability Distribution:

Problems of normal distributions can be solved using the z-score formula.

In a set with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the z-score of a measure X is given by:

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the p-value, we get the probability that the value of the measure is greater than X.

The average price for a gallon of gasoline in France is $5.54. The standard deviation is $.25.

This means that [tex]\mu = 5.54, \sigma = 0.25[/tex]

What is the probability that a randomly selected gas station in France charges more than $5.30 per gallon?

This is 1 subtracted by the pvalue of Z when X = 5.30. So

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

[tex]Z = \frac{5.3 - 5.54}{0.25}[/tex]

[tex]Z = -0.96[/tex]

[tex]Z = -0.96[/tex] has a pvalue of 0.1685

1 - 0.1685 = 0.8315

0.8315 = 83.15% probability that a randomly selected gas station in France charges more than $5.30 per gallon

Answer:

523.3

Step-by-step explanation:

The volume of a cone is 1/3 hB where h is the height and B is the area of the base.

Step 1: Find the area of the base (B). The base of a cone is a circle so use the formula pi*r^2. Plug in numbers. 3.14*10^2. 3.14*100=314

Step 2: Plug into the formula. 1/3(5*314) --> 1/3(1570)=523.3

Answer:

35/5 =7 dollars

Answer: 220 miles

Step-by-step explanation:

Let's write the equations for each case:

A Hertz Rent-a Car:

Charges a fixed amount of $40, plus a $0.10 per mile.

Then if you drive x miles, we get a total cost of:

C(x) = $40 + $0.10*x

Enterprise Rent-A-Car:

Chares a fixed amount of $18 plus $0.20 per mile, so if you drive x miles, the cost is:

K(x) = $18 + $0.20*x

Now, we want to find how many miles you can drive such that you would pay the same in both companies.

Then we need to find x such that:

C(x) = K(x)

$40 + $0.10*x = $18 + $0.20*x

Let's solve this for x.

$40 - $18 = $0.20*x - $0.10*x

$22 = ($0.20 - $0.10)*x

$22 = $0.10*x

$22/$0.10 = x

220 = x

So if you drive exactly 220 miles, you would pay the same in both companies.

Answer:

7 hours and 15 minutes.

Step-by-step explanation:

Draw a timeline for this question.

8.30 + 7 hours = 3.30pm or 15 30

3.30 + 0.15 minutes = 3.45 or 15 45

7 hours + 0.15 minutes = 7 hours and 15 minutes.

Answer:

P-E-M-D-A-S

Step-by-step explanation:

Ok, so start with what i call "P-E-M-D-A-S"

P: parentheses | Also known as these: ( )

E: exponents | Its a small number by another number, like the 3 on your screen

M: Multiply | Also Known as   x or a dot

D: Divide | i forgot how to make it

A: Add | also known as +

S: Subtract | also known as -

now go in order to solve it, it makes it much more easy!

Answer:

49 is your answer

Step-by-step explanation:

let's do b-pemdas

brackets

parentheses

e(I forgot the name for it but it's basically a small number next to the big number)

Multiply

Divide

Add

Subtract

you do the equation in that order

so

2+8•7-(3^2)

we focus on (3^2)

that's 3•3 which equals to 9

so now the equation is

2+8•7-9

Now we focus on 8•7 which equals to 56

the equation now looks like

2+56-9

you then add 56 to 2 which equals to 58 and then subtract 9 from it so it should look like this

2+56=58

58-9= 49

and 49 is your answer

hope this help!!!

Answer: The rate of change of the distance between the bottom of the rod and the base of the wall when the height is 35 inches = 1.02675 inches per second.

Step-by-step explanation:

Let h = height, x= distance between the bottom of the rod and the base of the wall.

Given: [tex]\dfrac{dh}{dt}[/tex] = 5 inches per second

Consider the diagram (given in the attachment below):

By Pythagoras theorem, we have

[tex](174)^2=h^2+x^2\ \ (i)\\\\$$30276=35^2+x^2 \ \ \ [h=35 \ in.]\\\\ 30276=35^2+x^2 \\\\ 30276=1225+x^2\\\\ x^2=30276-1225\\\\ x^2 = 29051 \\\\ x=\sqrt{29051}\approx170.447 in.[/tex]

Differentiate both sides of (i) w.r.t t, we get

[tex]0=2x\dfrac{dx}{dt}+2h\dfrac{dh}{dt}\\\\\dfrac{dx}{dt}=\dfrac{-h}{x}\dfrac{dh}{dt}[/tex]

[tex]\dfrac{dx}{dt}=\dfrac{-35}{170.44}(-5)=1.02675\text{ inches per second }[/tex]

Hence,  the rate of change of the distance between the bottom of the rod and the base of the wall when the height is 35 inches = 1.02675 inches per second.

Answer:

since g:B→C is onto

suppose z∈C,there exists a pre-image in B

Let the pre-image be y

Hence y∈B such that g(y)=z

similarly f:A→B is onto

suppose y∈B,there exists a pre-image in A

Let the pre-image be x

Hence x∈A such that f(x)=y

Now gof(x)=g(f(x))=g(y)=z

So for every x in A,there is an image z in C
